The most important part of the machine tool is the main part, the main part of the workpiece, the relative movement of the tool, the execution part of the table, the control part that controls the operation of the workpiece and the tool. The three basic parts are the main parts, the spindle parts, the bearing, the servo motor for the table drive. Machine, electric, liquid, gas, and optical components required for the replacement of ball screws and linear guide tools must meet the requirements of advanced machine tool workpieces, tools, motion, positioning, adjustment, compensation, and control. Claim.
In particular, the high-precision machine tools of the machine reach the micron level in terms of precision, and the nanometer level reaches 10,000, 20,000 or even 10,000, 10,000, 10,000, 10,000 r/mi in the spindle speed at fast moving speed. 1Zom/mi, the machine tool failure interval reaches O1-20 million h in the reliability of work. When machining any surface, NU day S (non-uniform rational daily spline interpolation) is needed when the machine is connected and communicates with the outside world. Need to use the network and so on. It has very high requirements on the accuracy, reliability and life of various components of machine, electricity, liquid, gas and light.
Taking the spindle components and bearings as an example, it is necessary to solve the problems of dynamic balance, heat generation, noise, etc. of each component under high-speed operation. Otherwise, vibration, thermal deformation, noise, etc. may cause the machine tool to work normally. Machine tools, automatic lines, FMS, automated workshops, FA (Automation factory) In the operation, if the reliability of the components of the machine tool is often faulty, it will cause serious damage in production. The total technical development direction of the matching machine, electricity, liquid, gas and optical components in the future is: miniaturization, precision, high speed, high reliability, long life, low price, good economy and durability.
