Main Features
- High cutting precision, strong rigidity, and high grinding efficiency. Ideal for cylindrical and conical workpieces.
- All moving components (workpiece, outer and inner grinding wheels, oil and cooling pumps) are driven by independent motors.
- Table longitudinal movement supports hydraulic stepless speed adjustment and manual control. Lubrication is performed via throttling discharge.
- All motion sections are interlocked via electrical, hydraulic, and mechanical safety mechanisms.
