Shanghai Wensha Precision Mechanical Element MFG Co., Ltd

Precision machining technology computer-aided design, finite element analysis techniques, especially the development of ultra-precision machine tools for the optimization of the overall structure of the design provides a convenient means of making the machine stiffness and stability continues to increase. At present the typical structure of single crystal diamond lathe with "T" type layout structure, the spindle is generally mounted on the X to the rail, the tool mounted on the Z-rail. In the past few years, with the rapid development of computer technology, ultra-precision machine tools of some key technologies, such as control technology, feedback systems, servo drives, etc. has made great strides to improve the accuracy of ultra-precision machine processing, At present, ultra-precision machining has been able to direct a surface roughness of 1nm. The development of these key technologies summed up in the following areas: natural granite with a machine bed, which has very high thermal stability and mechanical stability; the use of air spring vibration isolation system; use of liquid or gas hydrostatic guideways the damping increases, the movement is smooth, frictionless; DC linear motor drive system quickly, with good dynamic stiffness; high-speed air spindle, carrying capacity, high stiffness, can improve the precision; open computer numerical control technology (CNC), facilitate the application of third-party control software, improve the precision; high-resolution detection devices that can provide accurate position feedback; using fast servo, micro-macro multi-axis system with technology for processing of complex surfaces; on-line measurement and error compensation, correct measurement of workpiece residual error and eventually eliminate the error.
