- 2) max. clamping capacity only up to 24,000 rpm
- 3) non-ventilated, low noise
High-precision motors for hydro-clamp chuck systems
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
