Grinding spindle DGZX-08040/4.0-HSK

motorizedHSK-E 25water-cooled

Product overview
The HSK E25 interface enables the compact φ80 spindle DGZX-08040/4.0-HSK to support automatic tool change while delivering 4.0 kW continuous (S1) and up to 6.0 kW intermittent (S6). It reaches 40,000 rpm, uses ceramic ball bearings and is designed for water cooling. Interface rigidity and limited installation space are primary selection factors for this spindle.
