CG240
The CG240 is built to be very heavy with widely spaced ways to assure positive alignment of the wheelhead to the table. Moreover, the controls are easier to use. In particular, the 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".As an illustration of the superior accuracy of these machines, it is possible to double plunge precisely to the same size leaving no lap line. pic To achieve a major reduction in set-up time, the CG240 eliminates wasted effort at every step of the process. Some crankgrinders have some of the same features, but no other machine has all of the important advantages of the CG Series.
The CG240 has four indexing locations. When reading the indicator to determine journal offset, the operator knows the crank is turned precisely to the desired position and the indicator is giving an accurate reading. He need not repeat this step to recheck the measurement.
