CENTER HOLE GRINDING MACHINE

Grinding Wheel Spindle Head
● Grinding wheel spindle head is a
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
2
connect with 1~8kg/cm compressed air,
2
therefore, the oil mist produced 1.5~2kg/cm
pressure for lubrication.

Conical type Wheel Dressing Device
● 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 simultaneous back 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.
