Motor spindle for milling and grinding

The HVC 120 is a compact, high-speed motor spindle designed for mold making, micro-machining, and precision applications in the medical and graphite industries. With housing diameters as small as 120 mm and speeds up to 75,000 min⁻¹, it combines extreme precision with a minimal footprint.

STEP TEC

Highlights

Ultra-high speed

With speeds ranging from 48,000 to 75,000 min⁻¹, the HVC 120 is built for the most demanding high-speed milling and grinding applications, delivering maximum productivity and outstanding surface quality.

Extreme precision

Ultra-precise shaft roundness enables surface roughness down to Ra 0.02 µm, ideal for the tightest tolerances in mold making, medical, and micro-machining applications.

Contamination-free

Twin Air Sealing (TAS) prevents the ingress of graphite dust, coolant, and fine particles, broadening application suitability to include dirt-sensitive materials and dry machining environments.

Process monitoring

A built-in acceleration sensor continuously monitors vibrations and process behavior, maintaining compliance and process safety while accelerating part approval.
