CK40L chinese Computer controlled CNC mill lathe

2)The middle supporting plate together with the whole lathe bed, the middle slip plate and the sliding surface of supporting plate are all adopt the line rail technology of Taiwan, with fast speed, eliminating intermittent creep, high rigidity, low friction, and low noise characteristics. With automatic pressure lubrication, it improves the machine accuracy.

3)The feed of X, Z direction adopts the inner loop preloading large-lead ballscrew with double nut so it is of high feed speed. The drive motor connect with screw straightly via elastic coupling. The feed servo motor passes power to the high precision ball screw directly . It is no gap, and it ensures the accuracy of positioning and synchronization for the lathe

4)The spindle box adopts spindle unit which is of independent type and sleeve structure and it is equipped with high intensity special bearing for spindle. In terms of lubrication, it adopts the Germany special lubricating oil of bearing, which greatly reduces the thermal deformation of spindle unit and improves the thermal stability and accuracy. 

5)It uses a reliable device which is automatic and centralized to lubricate. It can lubricate automatically and intermittently to all lubrication points of CNC lathe. And it can settle lubricating time according to operating conditions.
