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.
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 and good rigidity, and can realize the forming and grinding of wide grinding wheel.
★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.
