WORKHEADS The workheads are designed with extreme precision both in the traditional system where cross movement ensures an easy and quick adjustement and in the orbital system where we find perfect synchronization with angular encoders. The positioning and repeatability are ensured by linear encoders with “closed loop” system. The workheads move on air cushion. AUTO-CLAMPING HYDRAULIC WORKHEAD WITH 3 JAWS CHUCKS Testa portapezzo idrauliche con mandrino autocentrante a 3 griffe HEAVY DUTY WORKHEAD 4 JAWS CHUCKS Testa portapezzo con mandrino a 4 griffe TESTE PORTAPEZZO Le teste portapezzo...

GRINDINGHEAD UNIT Testa portamola 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. Nei modelli più pesanti come il modello di macchina DB la testa portamola si muove sull’asse X supportata idrostaticamente ed è controllata da encoder lineari. I modelli ad alta produzione tipo il modello di macchina DU muove su...
