Description
Version:
Air-powered high-speed spindle, constant speed under load 25,000 − 65,000 rpm depending on the version. Power up to 1kW.
Advantage:
- Higher machining speeds with smaller tools.
- Protects the machine - speed is generated by the high-speed spindle - the machine spindle is stationary.
- Integral air cooling permits continuous use. No standstill times.
- Longer tool life.
- Very good surface quality of the tools - less requirement for regrinding.
Application:
High-speed spindles allow higher cutting speeds and feed rates. They allow above all the use of tools with small diameters (6 mm).
Supplied with:
High-speed spindle, collet, collet clamping nut, wrench, sealing plug, air filter, connection hose.
Optional extras:
Tool-change turret for automatic tool-change. Required only for external air supply - available on request.
Note:
Use clean dry compressed air at approx. 6.2 bar.
Further spindles available on request: all commonly-used shank versions, different performance classes and speeds.
