2. Wheelhead, Spindle System and Feeding Mechanism

Wheelhead spindle system utilizes four-shell dynamic pressure bearings.
Wheelhead feeding system is sub realized by AC servo motor driving ball type lead screw.
The ball type lead screw adopts domestic high-quality products with good rigidity and high motion precision.
Wheelhead guideway adopts flat-V sliding guide way. Guide way surface has been scraped manually so it has good positioning accuracy, abrasion resistance, rigidity and smoothness in low-speed movement.

4.Tailstock

Tailstock center tightens against the workpiece by the spring inside the sleeve. Tightening pressure can be adjusted by the compression of spring. The withdrawal of tailstock center can be controlled by hydraulic or manual operation.
