GSK988T Turning Center

GSK988T is a new CNC controller for siant bed CNC Iathe and tuming center, adopt micro processor of 400MHz high performance. and it can control five feeding axes (including C axis), two analog spindles,
real-time comrnunication between GSKLink serial bus and servo unit, the adapted servo motor adapts encoder of absolute type in high resolution, realize position of 0.1um, and satisfy the requirernents of
comibined processing of turning and milling in high precision. GSK988T is equipped with internet interface, and it supports remote monitor and file transmission and satisfies the requirements of internet education and workshop management. GSK988T is the best choice for stant bed CNC lathe and turning center.
