JHG-1510 Center Hole Grinding Machine

With exclusive 3D design of synchronized grinding motion, the machine will be very stable and automatically locates center.
1.Grinfing wheel rotation.
2.Planetary motion of grinding wheel spindle
3.Grinding wheel reciprocating motion will be along conical surface.
Based on three-axis simultaneous grinding action, grinding out heterogeneous pattern, with a small oil groove feature, oil film can be formed in a permanent between workpiece and center of cylindrical grinding machine.This is to prevent non-film stuck with the center and can eliminate unnecessary error, in order to facilitate high quality cylindrical grinding.

Grinding wheel spindle head is combination of the spindle head, planetary motion mechanism, wheel spindle, dressing device and spindle motion mechanism.
Rotating of grinding wheel spindle driven by 1/2HP x 2P motor, through the appropriate pressure tension of idler, driving wheel spindle in high speed rotating.The speed can be changed by frequency converter.
Planetary transmission device adopt 1/5HP x 8P motor, which can be simultaneously doing wheel spindle planetary motion and reciprocating motion along on conical surface.
Grinding wheel spindle use sleeve design, easy assembling, with 4 high-speed precision P4 class Angular ball bearings support in front and back and oil mist lubrication, have high speed and precision characteristics.

The atomizer device for grinding wheel spindle connect with 1~8kg/cm² compressed air, therefore, the oil mist produced 1.5~2kg/cm² pressure for lubrication.

This device placed on the side of grinding wheel head, can be manually rotate into dressing position and while dressing only wheel spindle rotating.During operation, the device moved longitudinal and the diamond dresser moved simultaneousback and forth oscillation of lateral motion, along the wheel cone linear movement.This ensures the consistency geometric accuracy of wheel shape, completely non-effect on dresser position and wearing.

Upper Swing center and Lower Center Device Keep upper swing center ad lower center consistency benchmark.

Automatic workpiece clamping simplify the setting job.(can be based on processing needs and provide different clamping devices)

While grinding, the workpiece driven simultaneous.It improves the center hole and cylindrical concentric accuracy, the speed can be changed by frequency converter.
