For various eccentric circle or non-round shape workpieces grinding purpose, PALMARY develop CNC Cylindrical Grinder Cam Type with CAD/CAM software for easily transfer from workpiece drawing to grinding program. The workhead could offer precise angle control upto 0.1 micron resolution due to the C axis has accurate angle encoder. The infeed axis is driven by linear motor with linear guideway & close loop linear scale, it could avoid the backlash in order to reach high machining precision. Also, it could prevent the reaction force causing by linear motor under the large acceleration and deceleration motion, it could stabilize the grinding process.This machine has high-speed algorithm controller execute under PC Based + Windows XP, allowing the 3rd party application and Flash Drive for prompt transfer, its single section processing time could be ≦ 1ms.
