Heavy-Duty Cylindrical Grinding Machine for Cylindrical and Conical Workpieces
The Heavy-Duty Cylindrical Grinding Machine is a reliable precision grinding solution designed for cylindrical surface grinding, conical surface grinding, internal grinding, shaft grinding, sleeve grinding, and high-accuracy metal part finishing. Based on advanced cylindrical grinder designs, this machine provides high cutting precision, strong rigidity, high grinding efficiency, and stable operation for demanding industrial machining applications.
This cylindrical grinder is suitable for grinding cylindrical and conical workpieces such as shafts, sleeves, rollers, pins, hydraulic components, mechanical parts, and other precision metal components. With strong machine rigidity and reliable grinding performance, it is suitable for both heavy-duty grinding and precision finishing tasks.
The workpiece spindle, external cylindrical grinding wheel, internal grinding wheel, oil pump, and coolant pump are driven by independent motors. This design helps improve operational stability, system reliability, and grinding process control during continuous machining.
The longitudinal movement of the machine worktable can be driven by hydraulic stepless variable transmission or operated manually by handwheel. This provides flexible operation for different grinding processes, workpiece sizes, and production requirements. The worktable lubrication system adopts an orifice-compensated unloading structure, helping support smooth movement and stable long-term performance.
