HPC 290 - Motor spindle for milling and grinding

The HPC 290 platform offers a broad range of metal-working solutions, not just outstanding spindles. The platform concept serves mold makers and part-production applications.
Ideal for roughing and finishing precision parts, the HPC 290 spindle platform accommodates housing diameters as small as 290mm, with speeds from 6,000 to 15,000 rpm, power from 35 to 66 kW S1 and torque from 279 to 512 Nm S1. The COOL-Core technology provide polar temperature stability for repeatable, reliable machining processes. The clamping capabilities of our spindle shaft interlock solution enable turning, milling and grinding with precise high throughput.
