Grinding spindle DGZ-0860

motorizedwater-cooledfor glass working

Product overview
The DGZ-0860 increases the speed capability of an 80 mm draw-in collet group to 60,000 rpm. A B095 tool interface, 2.5 kW continuous output (S1) and a water-cooled ceramic-bearing construction support faster grinding of precision glass components in industrial production environments.
