Life Insurance
Personal insurance protection is the human body, the life span of people. The basic elements of life insurance are: the insured (that is, people buy insurance) to the insurance company to pay a certain amount of insurance premiums, the insured person when the event of death, disability, disease, such as accident insurance, or live to the age of contract, insurance companies to the insured person or their dependents must pay the amount of insurance payments.
Insurance industry would normally be said that life insurance can be
Assist the public to solve the two major life questions: First, people die prematurely in case of questions; are two people live too long in case of questions. Why? This life insurance from the main functions of the two talking about. First of all, life insurance can be insured at the unfortunate deceased person to the bereaved family must be able to obtain financial compensation in order to maintain life and to pay debt; Secondly, life insurance can help people save money for future pension requirements. As played by these two tools, insurance products have one big advantage is that, according to China's tax law, insurance claims may be exempt from personal income tax.
Personal insurance, including life insurance, accident insurance and health insurance in three parts. In personal insurance, life insurance accounted for the vast majority (typically more than 80%).
Life insurance also can be divided into the survival of insurance, death insurance and insurance co-existence. Survive the so-called insurance, that is, if the insurance people to live up to the contract agreement on the age, insurance companies must be paid to the insurance money. Death insurance the contrary, if the insured person in the insurance contract when the unfortunate death of an effective, insurance companies must give the designated beneficiary of the payment. Well, regardless of life and death, want to have from how to do? Co-existence of insurance could meet this demand: the insured person is alive, the survival of insurance companies will pay insurance premiums; unfortunate death of the insured person, insurance companies pay death benefits.

Electric Vehicle repair
1, lubrication and maintenance are an important aspect of electric vehicles should be front axle, the central axis, flywheel, front fork shock absorber components, such as rotating the fulcrum of every six months to a year to conduct a scrub, on-demand add butter or oil.
2, adjust the brake system: The brake wire on the mounting screws loose, and then tightening or relaxing the brake wire, so that both sides of the brake block away from the cars circle the average distance of 1.5mm? D 2mm then tighten screws.
3, the electric line sometimes after a period of time the chain will be loose, adjust as follows:
Release the rear axle nut, screw tight chain will be deployed until the chain of elastic moderate, bearing in mind the rear wheel with the frame in parallel, and then tighten the nut on both sides. If the chain is tight, according to the above-mentioned method of reverse operation. Appropriate chain of elastic (sag 10mm? D15mm).
4, adjusting the level handlebar, the saddle on the attention of the security thread should not be exposed. And pay attention to the core screw fastening torque is not less than 18N.m.

type of CNC machine tools
At present, a lot of varieties of NC machine tools are usually several ways according to the following classification.
First, by way of sports classification
1, point-point control system control system control system are index only tool or machine tool control table, from the point Zonghuai indeed to move to another point, and between points and the trajectories do not need to exercise strict control system. In order to reduce the moving parts of exercise time and location, generally fast-moving first to the finish line near the location, then to low-speed and accurate positioning to move to the end position, in order to ensure good positioning accuracy. Moving the cutting tool is not. The use of such control systems have CNC jig borer, CNC drilling machine, CNC punching machine and so on.
2, point linear control system point linear control systems are control systems not only control the index or table knives and accurately from one point to move to the next point, but also to ensure that the exercise between two points is a straight-line trajectory of the control system. Mobile Tool cutting process can be carried out. Application of such control systems have CNC lathe, CNC drilling machine and CNC milling machine and so on.
3, contour control system control system, also known as contour cutting continuous control systems, control systems are able to index two or more axes simultaneously strictly continuous control system. It is not only moving parts that can be controlled from one point Zonghuai indeed point to move to another, but also control the entire process every point of the speed and amount of displacement will be processed into certain parts of the contour shape. Application of such control systems have CNC milling machine, CNC lathe, CNC machine tools and processing gear center.
Two, by control classification
1, open-loop control of CNC machine tools
Open-loop control system characteristics of the system are not detected feedback devices, one-way information transmission instruction, and instruction is issued, no feedback, so that the open-loop control.
By the stepper motor step accuracy and frequency, as well as transmission of the driving accuracy the impact of open-loop system in terms of speed and accuracy are lower. However, because of the open-loop control structure is simple and debugging easy maintenance, lower cost, are still being widely used on CNC machine tools.
2, semi-closed-loop control of CNC machine tools
Semi-closed-loop control of CNC machine tools is not a direct measurement of the displacement table, instead of using the angle of displacement detection components, measured servo motor or screw corner table projected actual displacement, feedback to the computer in the location of comparison, compared with the margin control. Because there is no feedback loop contains the table, so that semi-closed-loop control.
Semi-closed-loop control closed-loop control accuracy than bad, but good stability, lower cost, easier to debug than the repair, taking into account the open-loop control and closed-loop control characteristics of the two, so the more general application.
3, the closed-loop control of CNC machine tools
Closed-loop control system is characterized by the use of the installation work at the stage of detection components will be the actual table displacement feedback to the computer with the location of instructions required to compare the difference compared with control, until the margin eliminated. Can be seen that the closed-loop control system can eliminate all kinds of mechanical transmission components and workpiece error process generated by the impact of interference, thus greatly improve machining accuracy. The role of speed detection devices are servo motor will be converted into the actual speed signal to the speed control circuit, the feedback correction, guaranteed to keep the motor speed constant. Speed detection devices are commonly used electrical velocimetry.
Closed-loop control is characterized by high precision machining, mobile speed. This type of CNC machine tools using DC servo motor or AC servo motor as the drive components, motor control circuit is rather complicated, expensive detection devices. Debug and repair and therefore more complex and costly.
Three, according to technology use classification

First, by way of sports classification
1, point-point control system control system control system are index only tool or machine tool control table, from the point Zonghuai indeed to move to another point, and between points and the trajectories do not need to exercise strict control system. In order to reduce the moving parts of exercise time and location, generally fast-moving first to the finish line near the location, then to low-speed and accurate positioning to move to the end position, in order to ensure good positioning accuracy. Moving the cutting tool is not. The use of such control systems have CNC jig borer, CNC drilling machine, CNC punching machine and so on.
2, point linear control system point linear control systems are control systems not only control the index or table knives and accurately from one point to move to the next point, but also to ensure that the exercise between two points is a straight-line trajectory of the control system. Mobile Tool cutting process can be carried out. Application of such control systems have CNC lathe, CNC drilling machine and CNC milling machine and so on.
3, contour control system control system, also known as contour cutting continuous control systems, control systems are able to index two or more axes simultaneously strictly continuous control system. It is not only moving parts that can be controlled from one point Zonghuai indeed point to move to another, but also control the entire process every point of the speed and amount of displacement will be processed into certain parts of the contour shape. Application of such control systems have CNC milling machine, CNC lathe, CNC machine tools and processing gear center.
Two, by control classification
1, open-loop control of CNC machine tools
Open-loop control system characteristics of the system are not detected feedback devices, one-way information transmission instruction, and instruction is issued, no feedback, so that the open-loop control.
By the stepper motor step accuracy and frequency, as well as transmission of the driving accuracy the impact of open-loop system in terms of speed and accuracy are lower. However, because of the open-loop control structure is simple and debugging easy maintenance, lower cost, are still being widely used on CNC machine tools.
2, semi-closed-loop control of CNC machine tools
Semi-closed-loop control of CNC machine tools is not a direct measurement of the displacement table, instead of using the angle of displacement detection components, measured servo motor or screw corner table projected actual displacement, feedback to the computer in the location of comparison, compared with the margin control. Because there is no feedback loop contains the table, so that semi-closed-loop control.
Semi-closed-loop control closed-loop control accuracy than bad, but good stability, lower cost, easier to debug than the repair, taking into account the open-loop control and closed-loop control characteristics of the two, so the more general application.
3, the closed-loop control of CNC machine tools
Closed-loop control system is characterized by the use of the installation work at the stage of detection components will be the actual table displacement feedback to the computer with the location of instructions required to compare the difference compared with control, until the margin eliminated. Can be seen that the closed-loop control system can eliminate all kinds of mechanical transmission components and workpiece error process generated by the impact of interference, thus greatly improve machining accuracy. The role of speed detection devices are servo motor will be converted into the actual speed signal to the speed control circuit, the feedback correction, guaranteed to keep the motor speed constant. Speed detection devices are commonly used electrical velocimetry.
Closed-loop control is characterized by high precision machining, mobile speed. This type of CNC machine tools using DC servo motor or AC servo motor as the drive components, motor control circuit is rather complicated, expensive detection devices. Debug and repair and therefore more complex and costly.

Foreign exchange and stock
The distinction between foreign exchange and stock
1) The stock is one-way buy low and sell high, the stock if no one left to buy when it was put over, but do not throw out. And foreign exchange are two sides to you bullish on the buy up, called Zadok, you earned. You buy or put on, called short selling, you also earned. If you look the opposite direction and the actual lost, here is the bar with the short selling of many a battle between people. And want to throw at any time and without any restrictions.
2) the difference between the stock of foreign exchange and foreign exchange transactions are a 24-hour, from 4:00 to 4:00 the next day from Tokyo, London, Frankfurt to New York non-stop 24 hours a day except on weekends and statutory holidays abroad. The shares are 9:00 to 15:00.

Motor Principle
Motor Principle
Stator rotating magnetic field generated by the principle of
Rotating magnetic field: magnetic field refers to the location of the axis of rotation with time of the magnetic field.
At three-phase asynchronous motor stator iron hearts of three groups to place the structure of identical windings U1U2, V1V2, W1W2, each phase winding at each worse Spaces 120 ° electric angle, to the three-phase windings in the access to symmetrical three-phase alternating current, stator and rotor in the air gap to produce a rotating magnetic field.
To the bipolar motor that 2p = 2 as an example, symmetrical three-phase windings U1U2, V1V2, W1W2 assumed to be concentrated winding, three-phase windings into a star then, and pass to three-phase symmetrical currents iA, iB, iC. Such as shown in Animation. Assumed that the current instantaneous value is positive when the windings are the first from the inflow side, the end of the outflow. Current inflow end with "×" that the current outflow end with "" express.
wt = 0 when, iA = 0;
iB is negative, that is, iB inflow from the end of V2, the first outflow of client V1;
iC is positive, that is, iC from the first side W1 inflow, outflow of the end of W2.
Current inflow end with "×" that the current outflow end with "" express.
The use of right-handed helix can be set to determine at wt = 0 instantaneous three-phase current generated by the synthesis of the magnetic field direction, such as animated demo shown.
Synthesis of the magnetic field can be seen are a pair of magnetic poles, magnetic field direction and the vertical axis line direction, the top is the Arctic, the Antarctic are below.
wt = π / 2 when, iA is positive maximum, that is, iA flows from the first end of U1, U2 outflow end;
iB is negative, that is, iB inflow from the end of V2, the first outflow of client V1;
iC is negative, that is, iC from W2 inflow, W1 outflow.
Synthesis of the magnetic field direction can be seen more time wt = 0 when the direction of the needle turned 90o.
Empathy can draw wt = π, wt = 3π / 2, wt = 2π when the synthetic magnetic field, we can see the magnetic field direction by clockwise rotation, a total turn 360o, that is, rotating the week.
To sum up, in the three-phase AC motor stator has the structure of the layout at the same spatial location of the difference between the angle of 120o electric three-phase windings, respectively, access to three-phase alternating current, the stator and rotor in the air generated by the synthesis stator magnetic field is along the inner circle of rotation, it said rotating magnetic field.
Of induction motor working principle said that it should be easy:
When the three stator windings to the symmetry through the three AC, it produced a synchronous speed n1 along the stator and rotor space for inner circle clockwise rotation of the rotating magnetic field. N1 because of rotating magnetic field in order to speed rotation, the start of the rotor conductors are stationary, it will be cutting the rotor conductors in the stator rotating magnetic field generated inductive electromotive force (EMF sensing the direction of right-hand rule used to determine). Derivation because of the conductors at both ends by a short circuit shorted ring, at the role of inductive electromotive force, the rotor conductors and inductive electromotive force will produce basically the same as the direction of the induced current. Rotor current-carrying conductor in the stator magnetic field by the electromagnetic force (the direction of force is determined to use his left hand set). Electromagnetic force on the rotor axis electromagnetic torque, rotor-driven rotating magnetic field along the direction of rotation.
Through the above analysis can be concluded from the motor working principle is: when the motor of the three stator windings (the difference between the 120 degrees angle of electricity), access to the three alternating current will produce a rotating magnetic field, the rotating magnetic field cutting rotor windings, which at the rotor Winding generated induced current (rotor winding pathway are closed), current-carrying conductor of the rotor at the stator rotating magnetic field will produce under the electromagnetic force, which formed in the motor electromagnetic torque shaft, the drive motor rotation, and motor rotation direction with the rotating magnetic field the same direction.

Automotive maintenance and repair
1, the replacement of oil
2, the replacement of air filter, air-conditioning filter, oil filter, petrol filter
3, check whether the green battery in good condition, such as whether to measure voltage.
4, to check the entire vehicle electrical appliances, lights.
5, fastening screws chassis and suspension. Check whether there is any oil shock absorber
6, inspection wheel positioning is good, brake lining wear in the normal range, the remaining brake lining thickness is used to meet demand, otherwise the replacement.
7, each nacelle surface inspection.
8, to find a master craftsman, moving to hear the voices.
9, the replacement of spark plugs
10, change engine oil gear oil, check whether the brake shoe to be replaced, check the entire vehicle lighting electrical equipment, for the whole car add colorectal Wanxiang grease, check the entire vehicle shock absorber system, the direction of control systems, drive systems, as well as the most good cooling system will also replace the coolant tank is the water
11, the so-called vehicle maintenance refers to maintaining and restoring the technical performance of motor vehicles to ensure the car has a good use and reliability. It contains a lot of knowledge, correct and timely maintenance will extend vehicle life, improve safety, save money also taped much trouble repairing a car. However, today "to repair on behalf of Paul," the concept of the driver's team still exists, due to lack of security or maintenance of traffic accidents caused by improper happened frequently. So that timely proper vehicle maintenance is to extend the service life of motor vehicles to ensure road safety and an important element.
We usually said vehicle maintenance, mainly from motor vehicles to maintain a good technical condition, to extend the service life of automotive field. In fact, the broader its contents, including motor vehicles, such as beauty and skin care knowledge, summed up, the principal has the following three aspects:
First, body maintenance. Body maintenance habits also said the car Cosmetology. The main purpose is to remove cars and trucks in vitro in vivo oxidation and corrosion of all kinds, and then to protect the car as much as possible to highlight the "beauty." It mainly includes: Auto Paint maintenance, carpet cushion and maintenance, bumpers, skirts car maintenance, instrument maintenance Units, electroplating processing maintenance, plastic leather maintenance, tires, wheels warranty, windshield repair, chassis maintenance, engine maintenance and appearance.
Second, in-vehicle maintenance. Vehicle maintenance in order to enable the cars are forever young, in-vehicle maintenance purpose is to allow car several 100,000 kilometers without overhaul to ensure the car in the best technical condition. It mainly includes: lubrication system, fuel system, cooling system, brake system, carburetor (injector), such as maintenance.
Three, body renovation. Such as deep scratches on the diagnosis, treatment, multi-material bumper repair, leather, chemical fiber materials renovation, refurbishment, such as the color of the engine. Vehicle maintenance is divided into non-regular maintenance and regular maintenance of two categories, regular maintenance are: day-to-day maintenance, a maintenance, two maintenance; non-regular maintenance are: running-in stage maintenance and seasonal maintenance. The main vehicle maintenance job either cleaning, inspection, tight set, adjustment and lubrication, etc.. However, as science and technology and the development of the automobile industry to a variety of computer-based advanced technology widely used in the car so that the future fleet is gradually moving toward intelligent, and therefore the content of vehicle maintenance has been given a new connotation.
Vehicle maintenance is a relatively high technical complexity of work, I find it difficult to rely solely on the driver completed, the steam required to carry out repair business. Now in our country and also a number of automotive repair and maintenance businesses clinging traditional concept of letting go, and maintenance of obsolete equipment and tools, methods and means for maintenance or old, with this not meet the needs of modern development.

development of motor vehicle insurance
Automotive vehicle insurance, that is, motor vehicle insurance, referred to as auto insurance, refers to motor vehicles as a result of natural disasters or accidents resulting from personal injury or property damage liability insurance as a commercial.
Refers to motor vehicles are motor vehicles, trams, battery cars, motorcycles, tractors, all kinds of special machinery vehicles, special vehicles.
Automobile insurance is a kind of property insurance in the field of property insurance, automobile insurance is a relatively young insurance, which is due to motor vehicle insurance are accompanied by the emergence and popularization of motor vehicles and the emergence and development. At the same time, and the modern motor vehicle insurance are different in the early stages of automobile insurance based on car-based third-party liability insurance risk, and gradually extended to the body, such as the risk of collision damage
Early 20th century, automobile insurance industry in Europe and the United States has been developing rapidly. In 1903, the United Kingdom created a "universal car insurance", and gradually developed into the professionalization of a large automobile insurance companies. ?
In 1906, was founded in 1901 the Auto Union has also set up its own "Auto Union Insurance Companies." ?
To 1913, auto insurance has been expanded to more than 20 countries, automobile insurance rates and underwriting methods are standardized basic. ?
1927 history of the development of motor vehicle insurance are an important milestone. The United States, Massachusetts, developed the world-famous compulsory Motor Vehicles (Liability) Insurance Law promulgation and implementation, indicating that the motor vehicle third party liability insurance to start from voluntary insurance to the statutory compulsory insurance mode. Since then, the statutory motor vehicle third party liability insurance will soon spread to all over the world. Third party liability insurance for a wide range of statutory implementation, greatly promoted the popularity of motor vehicle insurance and development. theft insurance, cargo insurance and other services have also developed

High-voltage inverter
Inverter main circuit can be largely divided into two types: voltage source and current source type. Voltage source is to transform the DC voltage source for the exchange of the inverter, DC loop filter components are capacitors; current source type is to transform the DC current source for the exchange of the inverter, the DC loop filter components are inductors.
2, Why inverter output voltage and frequency changes in proportion?
Asynchronous motor is the motor torque and rotor flux of the current flow resulting from the interaction between the rated frequency, if the voltage must only reduce the frequency, then the magnetic flux on too large, the magnetic circuit saturation, motor current increases, serious motor when burned. Therefore, the frequency and voltage in proportion to change, that is to change the frequency of simultaneous control of inverter output voltage to maintain a certain flux motor to avoid the emergence of the phenomenon of magnetic saturation. This is the definition of VVVF. Here refers to the electric voltage of the line voltage or the RMS phase voltage.
3, motor-driven use-frequency power supply, the voltage drop in the current increase; for inverter-driven, if the frequency when the voltage drop also fell, then whether or not to increase current?
Frequency decreased (low), if the same power output, the current increase in torque under certain conditions, the current is almost unchanged.
4, the use of inverter operation, the motor starting current, starting torque how?
The use of inverter operation, with a corresponding increase in motor speed up the frequency and voltage, starting current is limited to 150% rated current the following (based on different models for 125% ~ 200%). Employment start-up frequency power directly, the starting current for the 6 ~ 7 times, therefore, will have the impact on electrical machinery. Using inverter drive can smoothly start (start-up time longer). Starting current for the rated current of 1.2 ~ 1.5 times starting torque for 70% ~ 120% rated torque; for a torque converter automatic enhancements, starting torque 100% or more, you can start with full load.
5, V / f mode What does this mean?
Frequency when the voltage drop V is also decreased in proportion, this issue has been in answer to 4 shows. Maintain the V / f constant control over asynchronous motor VVVF control the most basic way, it in the control of power frequency electric change at the same time control inverter output voltage, and both the ratio of V / f constant, thus enabling the motor to maintain a constant flux. Rated in the motor running, the motor stator resistance and leakage reactance voltage drop is relatively small, the motor terminal voltage and the induction motor equivalent-potential approximation.

Metal Cutting Machine Tool
Metal-cutting machine to be installed in the corresponding basis, is due to have the weight of machine tool and workpiece, the processing process has dynamic load will result in vibration, impact on equipment accuracy and life expectancy, the impact of product quality. Therefore, in order to ensure that the work of precision machine tools, in addition to guarantee the manufacture of precision machine tools, the basic quality of machine tools is also an important factor. One should consider the basic design of the basic requirements of (1) with the basic equipment required to adapt to the base and to ensure that the equipment installed by a solid and reliable. (2) have a basic enough strength and rigidity, to avoid severe vibration equipment to itself or the surrounding equipment processing accuracy and life expectancy will not be ultra-poor. (3) should have the basic stability and durability, to prevent groundwater and hazardous liquid erosion, does not guarantee the basic deformation or subsidence. Protective layer, if necessary, be added, such as the basic surface of asphalt, asphalt felt, such as mats. (4) based on product technology and easy to use basic elevation decisions to ensure the iron, cooling liquid, such as to facilitate discharge. Electrical equipment as much as possible a separate column under the plant, the frequent use of the area in the province. (5) large-scale equipment for basic, pre-installation of equipment in the best pre-pressure (pre-press equipment and the maximum weight of workpiece weight and 1.25 times). (6) adhere to basic conservation principles of design to maximize the savings of its materials and labor costs. 2 basic design is based on (1) equipment equipment manuals to provide the performance, main technical parameters, the electrical and auxiliary equipment such as pipe layout and fixed conditions. (2) basic equipment to bear all the static and dynamic load data. (3) Process equipment installation site layout plans, construction sites basic geological structure, hydrological conditions and soil type, composition and nature, and its data can be obtained from plant design data at the time of Geological Survey. 3 machine-based design (1) basic foundations are usually not subject to restrictions of natural soil types. Design strength is greater than 1kg/cm2 soil P can be used as basic foundation of general machine tools. (2) light machine (weight of less than 4 t) generally can be directly installed in the 150 ~ 200 mm thick concrete Pingshang. Heavy machine tools (such as vertical lathe, planer gantry, gantry milling machine, etc.), high dynamic load of machine tools (such as the Tau plane), on the ground vibration-sensitive precision machine tools (eg, jig borer, grinding machine, etc.) should be installed in a separate block-type basis.
Modular Machine Tool
Modular Machine Tool is based on generic components, together with the workpiece in accordance with a specific shape and design of a dedicated processing components and fixtures, composed of dedicated semi-automatic or automatic machine tools.
Combination of the use of multi-axis machine tools in general, multi-knives, multi-process, multi-faceted or multi-stage processing means at the same time, production efficiency than general-purpose machine tools to high several times a few times. As the generic components have been standardized and seriation, can be flexible configuration, can shorten the design and manufacturing cycle. Therefore, the combination of both machine tools and high-efficiency low-cost advantages of large, mass production to be widely applied, and which is part of automated production lines.
Combination of machine tool for processing the general Box-type or an extraordinary shape parts. Processing, the workpiece generally does not rotate, the rotary movement by the tool and tool and workpiece relative to the Progressive Movement, to achieve drilling, reaming, countersink holes, Reaming, boring, milling plane, internal and external thread cutting and processing Excircle and face, etc.. Some combination of the first gripping tool used for turning the workpiece so that rotation, by the tool for feed motion, but also realize some rotary parts (such as the flywheel, automotive rear axle, etc.) of the cylindrical and end-processing.
Twenty-first century since the 70s, with the turning tool, Micronesia-tooth milling cutter, Boring tool size automatic detection and automatic compensation technology, combination machine tool machining accuracy is also improved. Milling plane flatness up to 0.05 mm / 1000 mm, surface roughness can be as low as 2.5 ~ 0.63 microns; Boring accuracy IT7 ~ 6 level Distance precision of up to O.03 ~ O.02 micron.
Dedicated machine, with the rise of the automobile industry and developed. The dedicated machine due to the repeated use of certain parts, and gradually developed into a general-purpose components, resulting in a combination of machine tools.
A combination of the first machine is manufactured in the United States in 1911, and for the processing of auto parts. Initially, the machine tool factory GM parts have their own standards. Factories in order to improve different parts of the interchangeability of generic, user-friendly and maintenance of the United States in 1953 Ford Motor Company and General Motors Corporation and the United States machine tool factory in consultation identified a combination of machine tool components standardized general principle that strictly require that all links between components of size, but not provided for the structural components.
GM parts can be classified according to the functions of dynamic components, bearing components, transmission components, control components and auxiliary components of five categories. Driving force for the combination of machine tool components to provide the main movement and feed movement of the parts. Main driving force for me, the cutting head and power slides.
Support for the installation of dynamic components is a slipway with a feeding mechanism of the cutting head or fixtures and other components, has the side base between the base, frame, adjustable frame, column and column base and so on.
Conveyor components for the purpose of transmitting or workpiece spindle box position to processing components, the main rotary table who have degrees, the ring sub-degree rotary table, dividing drum and reciprocating mobile platforms.
Control unit is used to control machine tools, automatic working cycle components have hydraulic station, electrical cabinets and control panel and so on. Auxiliary components have lubrication devices, cooling devices and Chip devices.
In order to enable the combination of machine tools can be applied to small and medium-volume production, it often requires the application of group technology, similar to the structure and process components concentrated in a combination of machine tool processing, in order to improve the utilization of machine tools. This type of machine has two types of commonly available-for-box-type combination of machine tool spindle and turret machine tool portfolio.
