CG 270A/2000
CRANKSHAFT GRINDING MACHINES

OPERATION
The crankshaft grinding machines model CG have peculiar characteristics that permit easy and quick set-up and operating of the crankshaft.These qualities have been reached after a particular study and realization of the headstock and of the relative tailstock.

1- Precise connection between the prismatic and flat guides of the basement with the table permit an high stability and a perfect perpendicularity with the wheelhead.

2- Big base to permit the working of big crankshaft without extending the table beyond the base for more than the 10% of its length.

3- Group of leveling points for a better leveling and for the corrections of eventual distortions of the machine
