SK40P Series horizontal CNC lathes that spindle speed are changed mechanically in three gears together with control of a frequency changer. The lathe has 4 types (750, 1000, 1500, 2000). Equipped with 4-station (standard)/ 6-station turret (optional), the lathes are available for different cuttings. The sliding door ensures the operator’s safety. CNC systems such as GSK 980T,FANUC 0i TF(5),etc. is provided on request. The lathes can perform internal and external cylindrical turning, arbitrary taper turning, arc turning, facing and threading. They are suitable for various middle or small batch production, especially for complicated and high accuracy workpieces.
