WMS series CNC cylindrical grinder is suitable for automatic precision grinding of taps, milling cutters and other cutters. The automatic feeding mechanism, NC three-axis manipulator, RB6 six-axis multi-functional robot and on-line measurement and selection of parts designed by Peiping Machine Tool Patent can be used to carry out from small batch production to long-term unmanned automatic grinding. Direct drive/linear motor can be used for workpiece axis and linear axis, and Heidehan/Renishau grating ruler can effectively control the accuracy of machine tool. The choice of marble bed can resist earthquake and reduce the influence of low temperature change. Three-axis linkage can grind non-circular cam surface. Improve the accuracy of grinding interpolation, ensure high precision of conical and circular grinding and surface roughness of parts.
