HPC 240 - Motor spindle for milling and grinding

The HPC 240 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 240 spindle platform accommodates housing diameters as small as 240mm, with speeds from 10,000 to 25,000 rpm, power from 24 to 50 kW S1 and torque from 52 to 248 Nm S1. Twin Air Sealing (TAS) broadens application suitability to include contamination-free production in dirt-sensitive materials such as graphite. Easy-to-implement tilting head solution boosts efficiency.
