CNC crank grinder
★This machine tool is suitable for eccentric cylindrical grinding of small crank parts in the compressor industry.
★The machine tool adopts an L-shaped bed structure, and the operator performs the operation of loading and unloading the workpiece on one side of the grinding wheel, which is convenient, safe and reliable to operate.
★Adopt imported two-axis numerical control system, built-in PLC and liquid crystal display.
★The head frame motor adopts servo motor to realize stepless speed regulation.
★The grinding wheel spindle bearing adopts the overall large taper forming oil wedge dynamic pressure bearing, which has high rotation precision and high rigidity.
★The movement of the grinding wheel frame and the worktable is driven by AC servo motor through ball screw, and the feed guide of the grinding wheel frame and the worktable adopts imported linear guides to ensure accurate and sensitive feeding.
★Configure independent electrical cabinet, fuel tank and water tank.
★The machine is equipped with a full protective cover, which can automatically open the door and manually close the door for safe operation.
★It is equipped with automatic measuring instrument on-line detection to realize closed-loop automatic grinding work cycle and ensure high grinding dimensional accuracy.
