CNC high-speed cylindrical grinding machine
★This series of machine tools adopts imported two-axis linkage numerical control system, built-in PLC and liquid crystal display.
★The movement of the grinding wheel frame and the worktable is driven by the AC servo motor through the ball screw, and the grinding wheel frame feed guide is adopted.
Imported linear rolling guides are used, and the worktable adopts
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 can adopt AC servo motor to realize stepless speed regulation, and the exact stop position is more accurate.
★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.
