Perske high-precision motors are developed especially for hydraulic chucks. By using a reinforced bearing with high-precision ball bearings and a stiffer spindle, outstanding axial and radial run-out can be achieved in micron-level quality.

In combination with our precision balancing, we offer smooth-running, maximum-precision drives that are especially well-suited for use with PKD tools and can substantially increase their service lives. The result is improved cost-effectiveness and availability.

Perske high-precision motors are characterized by

  • Stiff motor spindles and precision bearings with double spindle bearings
  • Ground and hardened shafts
  • Radial and axial run-out precision ≤ 8 microns
  • Uniform interface for milling and cutting tools
  • Significantly longer tool service life
  • No-play tool clamping
