HF-spindle 8022 water cooled 2.2 kW ER20

This motor spindle from the HFS series can be used wherever milling and engraving work is required, e.g. on wood, plastics and aluminum at speeds of up to 24,000 rpm.

Brief overloads are easily possible due to the perfectly coordinated liquid cooling in the entire speed range up to 24,000 rpm. In addition, the running noise is extremely quiet even at high speeds, since there is no speed-dependent fan noise.

With a weight of only 4.8 kg and an ER20 collet holder, tools with a diameter of up to 13 mm can be clamped. The motor spindle has a torque of 0.90 Nm and offers users very good performance even when milling with a higher chip removal rate.
