China Ck6730 CNC Lathe

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.4000 rev/min,turning roughness is up to Ra08~04.
3. The width of Z to 355mm peak type quenching , plastic guideways , with high rigidity and abrasive resistance.
4. Precision ball screw is locatePneumatic/electric drilling/milling unit
5. 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.
6. The unique dovetail comb type tool block ensure easy setting,quick and precise tool change and maximum repeatability.
7. Turret board equipped with automatic feeding machine,it's convenient achieve the corporation automatic through CNC control system.
8. The high performance intermittent centralize lubrication system lubricates the guideways and screws, making sure the lathe keep the good lubrication sate.
9. 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.
