Features


1. The integrated base and bed casting has undergone a strict aging treatment, so high accuracy and rigidity is ensured.

2. High precision cartridge type spindle is equipped with a linear cylinder and collet chuck; the spindle rotates smoothly at high speed and turning roughness is up to Ra0.8~0.4.

3. Precision hardened dovetail guideways improve the total rigidity of lathe so that the lathe has high precision and runs smoothly.

4. Precision pretensioned ball screw is located between guideways; side torque is eliminated. Imported bearings especially for screws are used and smooth transmission is ensured.

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 ensures easy setting, quick and precise tool change and maximum repeatability.

7. The high performance intermittent centralized lubrication system lubricates the machine bed guideways and X/Z-axis screws in time.

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

9.  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.

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

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