four-station and variable speed CK40Y CNC Lathe

1, high efficiency and performance; 2, strong rigidity and easy to operate; 3, reasonable price;

This model is a kind of 6140 economical lathe with low-speed and strong power for its high quality, reasonable price and high rigidity. Being widely used in machinery, electronics, instruments, light industry and other industries especially in motorcycle spare part and auto industry, it is suitable for the large-batch workpieces to do the semifinishing and finishing.

ⅠThe characteristic

1, The lathe bed is flat with a slide guide and whole bed foot. The guile rail of lathe bed be quenching. The guile rail of Sliding base be laminating.

2, The principal axis by frequency control of motor speed ( 3 grade), 21-1600r/min (21-210r/min;80-800r/min;160-1600r/min)

3, Servo drive or stepper, being in possession of thread function.

4, The electronic knife rest with four-station.

5, Manual chuck: you can choose the hydraulic chuck

6, Manual lubrication: you can choose the automatic lubrication

7, Half protection: maneuvering box at right side and sliding door to left side.

8, Control system: GSK, KND, HUAHZONG and RENHE are made in China; FANUC and SIEMENS are imported brands.

9, Standard configuration is succinct and effective. The chosen spare part is more sufficient.
