CG260-1500 Crankshaft grinding machine
ENGINE REBUILDING - CRANKSHAFT
| High precision means superior high performance. | |
 |
|
|
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 CG260-1500 '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. The superior accuracy of this machine allows double plunge grinding precisely to the same size leaving no lap line. CG260-1500 provides longe machine life, longer grinding wheel life and greater safety for the operator and machine. |
