Crankshaft grinding machines

Made up of a cast iron normalized body, stabilized and well ribbed, able to support the weight of the piece and the forces generated during the grinding operation.

The pendulum movement allows quick and easy centering of the crankpins: moving is detected by a dial indicator.

Zero setting is achieved by moving the heads against a center stop, which can be switched off in case of a correction in the opposite direction.

360° Rapid rotation of the chuck
Chuck Easy replacement
Use of only two keys for all the operations of moving, centering and fixing

Workhead is equipped with a spindle rotating on bearings of high precision, which ensure tight tolerances and high rigidity in the working.
The spindle rotation with three-phase motor polarity (two speeds of rotation or, on request, variable).
