GSK218MC series CNC systems are upgraded products from GSK218M. As the high-speed spline interpolation algorithm is employed in the system, the machining speed and precision and surface fineness are greatly improved. The new-designed interface is user-friendly: The CNC system supports GSK-Link Ethernet bus function and it is much easier to connect; and supports macro programs of statement type (macro B), which makes the programming more concise. The CNC system can be applied in such areas as Milling Machine, Machining Center, high-speed Engraving, Grinding Machine and GearHobbing Machine.
