Product Description
Main Features:
1. We adopt special type plain bearing at the spindle nose.
(the external is conical, the internal is cylindrical) this kind of structure is long serves life.
2. We adopt a motor built-in type motor structure.
3. This structure is compact and excellent rigidity.
4. Worktable longitudinal movement and grinding head cross movement is supported by hydraulic system.
5. They are stepless and variable speed.
