CK61160 CK61180 CK61200 CK61220 CNC Heavy duty lathe

Feature

1.      This series of machine is CNC heavy duty horizontal lathe suitable for roughmachine and finish machine of ferrous and non-ferrous metal workpiece with carbide ceramic and other tools in facing external cylindrical turning internal, taper cutting and curved shape.

2.      Machine bed has three guideway or four guideways on one-piece casting and induction hardened to guarantee high accuracy. Heavy load capacity and long life. Carriage guideways are full protected with metal plate splash guards.

3.      Main spindle drive is DC inverter motor with three step hydraulic shift that brings wide range of speed change of 1:200., two step change headstock has spindle direct connected chuck structure. Main spindle is supported by imported high precision radial backlash adjustable double-row cylinder roller bearing in optimal distance considering supporting distance and chuck diameter to get the best accuracy and stiffness.

4.      X-axis and Z-axis movement is controlled by AC servo motors X-axis adopts imported high precision ball screw and Z-axis adopts imported high precision backlash-free warm-rock structure to guarantee the highest feed accuracy and rapid traverse.

5.      Various types of steady rests, roll chock grinding attachment and milling attachment are available as optional according to customer¡¯s choices
