CNC high-speed cylindrical grinding machine
★This machine adopts imported two-axis numerical control system, built-in PLC and liquid crystal display.
★The feed of the grinding wheel frame and the movement of the worktable are driven by the AC servo motor through the ball screw, and the grinding wheel frame feeds
Imported linear guides are used for the guide rails, and the worktables are used
Hydraulic oil forcibly lubricates the flat-V guide rail to ensure accurate and sensitive feeding.
★The grinding wheel frame motor adopts AC frequency conversion speed regulation device, which can basically realize constant linear speed grinding.
★The grinding wheel spindle bearing adopts dynamic and static pressure bearing, which has high rotation precision, good rigidity and can realize wide grinding wheel forming
★The head frame motor adopts AC variable frequency speed regulation device to realize stepless speed regulation.
★The tailstock sleeve has hydraulic telescopic function.
★The machine tool is equipped with a full protective cover, and the operation is safe and reliable.
★Equipped with automatic measuring instrument online detection to realize closed-loop automatic grinding cycle.
