CG270-2000 Crankshaft grinding machine

Longer life with less upkeep and repairs.

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 CG270's are built very heavy with widely spaced ways to assure positive alignment of the wheel head to the table. Moreover, the controls are easier to use. Precision Incremental In-Feed Lever is much easier to use than a hand wheel to achieve the precise desired journal size. One full stroke of this lever moves the wheel head precisely .0004”, and it can be used in steps to move the wheel head .0001”, .0002”, or .0003”. The superior accuracy of this machine allows double plunge grinding precisely to the same size leaving no lap line.
