The develope for CNC turning lathes.

2. High precision
  The accuracy requirements of automated CNC lathes are now not limited to static geometric accuracy. The movement accuracy, thermal deformation, and vibration monitoring and compensation of machine tools are getting more and more attention.
(1) Improve the control accuracy of CNC system: adopt high-speed interpolation technology, realize continuous feed with small program segments, make CNC control unit refined, and adopt high-resolution position detection device to improve position detection accuracy (Japan has developed and installed 106 pulse/revolution AC servo motor with built-in position detector, its position detection accuracy can reach 0.01μm/pulse), the position servo system adopts feedforward control and nonlinear control methods;
(2) The automatic CNC lathe adopts grid inspection and improves the accuracy of the motion trajectory of the machining center, and predicts the machining accuracy of the machine tool through simulation to ensure the positioning accuracy and repetitive positioning accuracy of the machine tool, so that its performance is stable for a long time and can be operated under different operating conditions. Complete a variety of processing tasks and ensure the processing quality of the parts.
   (3) Adopt error compensation technology: adopt backlash compensation, screw pitch error compensation and tool error compensation technology to comprehensively compensate the thermal deformation error and space error of the equipment. Research results show that the application of comprehensive error compensation technology can reduce processing errors by 60% to 80%;Previous: No InformationNext: Talking about the future development of lathes in the machining industry.
