CNC High Precision 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 made of hydraulic oil.

Oil-supplied flat-V injection guide rail, accurate and sensitive feeding; equipped with electronic handwheel, easy to operate.

★The grinding wheel spindle bearing adopts large taper dynamic pressure bearing, which has high rotation precision and good rigidity.

★The head frame is controlled by servo motor to realize stepless speed regulation.

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

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