CG300-2200 Crankshaft grinding machine

Faster, easier set-up then other crankshaft grinders.

Four indexing locations on the head stock with the air operated index pins make it faster to dial in the crankshaft properly.
Easily adjusted outboard counterweights never need to be supplemented by inboard weights.
The CG300's are built very heavy with widely spaced ways to assure positive alignment of the wheelhead to the table. Moreover, the controls are easier to use. Precision Incremental In-Feed Lever is much easier to use than a handwheel to achieve the precise desired journal size. One full stroke of this lever moves the wheehead precisely .0004”, and it can be used in steps to move the wheelhead .0001”, .0002”, or .0003”. The superior accuracy of this machine allows double plunge grinding precisely to the same size leaving no lap line.
CG300 provides longer machine life, longer grinding wheel life and greater safety for the operator and machine.
