Twin wheels spec. grinder that achieves high accuracy, high productivity, and flexibility
CBN crankshaft grinders
GF50MS / GF50MH
Outline
Reduced no. of grinding steps due to closer proximity between the left and right wheels
By making the closest proximity between the left and right wheels 18 mm, compared to the previous 50 mm, it has become possible to grind the pin and adjacent journal simultaneously. This has reduced the number of grinding steps and cycle time. (Not needed with shoulder grinding specifications)
Reduced set-up changeover due to a pin phase indexing system
Increase productivity with a pin phase indexing system using a touch sensor. It supports various workpieces with differing pin diameters and pin strokes, significantly reducing set-up changeover time. (also used for wheel diameter control and endface indexing)
