CNC Crankshaft Thrust Surface Grinder
★This machine adopts imported three-axis 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 is driven by the AC servo motor through the ball screw, and the feeding of the grinding wheel frame adopts the
Imported linear rolling guide, accurate and sensitive feed; equipped with electronic handwheel, easy to operate.
★The grinding wheel spindle adopts imported rolling bearing structure or electric spindle structure, which has good rigidity and rotation accuracy.
★The head frame is driven by servo motor to realize stepless speed regulation. With precise circular position parking function.
★The axial positioning of the workpiece adopts an air-tight sleeve structure, which automatically completes the detection function of the workpiece axial position.
★The machine tool adopts CBN grinding wheel and is equipped with a front diamond roller dressing mechanism, which can automatically dress and compensate automatically.
★Equipped with imported anti-collision and air-elimination devices.
