EGH series


Center Hole Grinder EGH-1015
  • The quality of cylindrical grinding will depend on the center hole circular geometrical accuracy.
  • Based on three-axis simultaneous grinding action , grinding out heterogeneous pattern.
  • With exclusive 3D design of synchronized grinding motion ,the machine will be very stable and automatically locates center.
  • Grinding wheel spindle head is a combination of the spindle head, planetary motion mechanism, wheel spindle , dressing device and spindle motion mechanism.
  • Conical type wheel dressing device
  • Automatic workpiece clamping simplify the setting job.(can be based on processing needs and provide different clamping devices)
