HF-Spindle Mechatron HFSAC-8022 air cooled 2.2 kW ER20

This motor spindle of the HFSAC series is the most powerful, air-cooled variant and 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.

With a weight of only 4 kg and an ER20 collet holder, tools with a diameter of up to 13 mm can be clamped.
Thanks to active air cooling using an integrated fan wheel, there is no need for external cooling systems.

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.
