The CK series of CNC lathes feature a strong cast base and an exclusive slant bed structure which provide excellent rigidity, dampening and convenient chip removal. The high precision through-hole spindle, driven by a powerful A.C. main motor, features stability and low noise during operation. Key parts like the NC system, turret, chuck and bearings on the ball screw and main spindle are products of highly respected international vendors.
