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.
