CNC Universal Cylindrical Grinder


Machine Features:

 

★This series of machine tools adopts imported two-axis linkage numerical control system, built-in PLC and liquid crystal display. The machine tool adopts a fully enclosed structure.

★The movement of the grinding wheel frame and the worktable are driven by AC servo motors through ball screws, and the feeding guides of the grinding wheel frame and the worktable are all driven by hydraulic oil

Forced oil supply type flat-V guide rail, accurate and sensitive feeding; equipped with electronic handwheel, easy to operate.

★The grinding wheel spindle bearing adopts integral pad dynamic pressure bearing, which has high rotation precision and good rigidity. Equipped with a dedicated circulating oil supply and cooling system, the temperature rise is low.

★The head frame adopts AC frequency conversion speed regulation device to realize stepless speed regulation. Mechanical step-by-step speed regulation can also be used.

★The tailstock adopts hydraulic telescopic sleeve structure to realize hydraulic advance and retreat and spring clamping functions.

★Equipped with automatic measuring instrument online detection to realize closed-loop automatic grinding cycle.
