CNC Crankshaft Thrust Surface Grinder
This machine tool is suitable for grinding the thrust surface of automobile engine crankshaft.
★ 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.
Imported linear guide rails are used for the guide rails, and the workbench adopts imported linear guide rails.
Hydraulic oil forcibly lubricates the flat-V guide rail to ensure accurate and sensitive feeding.
★The grinding wheel frame adopts high-rigidity electric spindle to adapt to the high-speed grinding of CBN grinding wheel, and is equipped with AC frequency conversion speed regulation device
Set, the CBN grinding wheel line speed is 80 m/s.
★CBN grinding wheel dressing is realized by using high-speed dressing motorized spindle to drive diamond rollers.
★The machine tool is equipped with grinding wheel dynamic balancing, empty distance and anti-collision device.
★The head frame motor adopts AC frequency conversion 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 on-line detection to realize closed-loop automatic grinding cycle.
