Features
- Integrated base and bed made of high grade cast iron is of high rigidity .
- High grade cast iron saddle and slide, plastic-coated ways, small dynamic and static friction force. Wide span saddle and slide ensure large-loaded and heavy cut.
- The spindle runs in precision large diameter angular contact ball bearings and double -row cylindrical roller bearings, driven by heavy servo motor, and ensures extremely stiffness and large torque at low speed.
- Ball screws are used in X and Z axes, which are supported by Japan NSK angular contact bearings especially for screws. Therefore stiffness and heat distortion resistance of screws, and feeding accuracy are greatly improved.
- Well sealed machine electric cabinet together with air conditioner inside the cabinet guarantee correct operation of the control in high temperature and humidity ambient.
- Close attention is focused on edge technology. So machine guard is reliable. No chip, coolants is splashed or flies out when during heavy cut or pressure spraying of coolant.
- The chuck is clamped and unclamped hydraulically. The quill of tailstock is advance out and in. Both of them can be program controlled.
