CNC lathe -CK7663Z
Introduction
CK7663Z lathe is a high efficiency special purpose machine designed for turning outer/inner bearing rings from blank to pre-grinding stage. It is suitable for large batch production and has the following features:
1) 60 degree slant bed type structure provides easy chip removal. Wide span rectangular guide ways used in X-axis and Z-axis ensure high rigidity.
2) High torque and rigid spindle structure ensures high productivity.
3) Comb type tool rest offers fast tool change.
4) Domestic CNC control and frequency inverting spindle meet machining demand with high performance-price ratio.
