CRANKSHAFT GRINDING MACHINES In the heavy duty models like DB machines the grinding wheel head moves on X axis with hydrostatic guideways controlled by linear encoders. In high productivity crankshaft grinding machines like the DU machines the whleehead moves on X and Z axes with linear motors. The grinding wheel head movements can be traditional or orbital. “CHASE THE PIN” ORBITAL SYSTEM The orbital system means that the grinding wheel chases the crankpin, the workpiece rotates on the centerline and AG is not necessary to have different setup. Nei modelli piu pesanti come il modello di macchina...
