                                           CK6730CNC Lathe


Features:
1. The integrated base and bed is casted through resin mold,which has undergone a strict aging treatment,so high accuracy and rigidity.

2. The spindle is equipped with high speed hydraulic rotating cylinder and precision draw down collet chuck.It rotates max.5000 rev/min,turning roughness is up to Ra08~04.

3. Precision ball screw is located between guideways,side torque is eliminated. imported bearings especially for screws are used and smooth transmission is ensured. 

4. Feed screws in longitudinal and cross direction are directly connected with AC servo motors through zero clearance shaft couplings. High accuracy is ensured in transmission.

5. The unique dovetail comb type tool block ensure easy setting,quick and precise tool change and less  repeatability.

6. The high performance intermittent centralize lubrication system lubricates the guideways and screws of X/Z-axis in time.

7. The NC controller has color display and USB port, so data transfer is simple.

10. The external electric cabinet is easy to service. The separate rear mounted coolant tank and chip box ensure fluent chip disposal and easy chip removal.

11. The machine is jointly driven mechanically, electrically and pneumatically. Famous brand pneumatic and electric elements used on the lathe operate reliably.

12. Full enclosed stainless steel guard ensures safe and friendly operation.
