Description
Neostar magnetic chucks are universal in use, in particular for internal cylindrical grinding, turning and hard turning.
Compared with chucks with parallel pole division, the uniform radial pole division offers significant advantages, particularly when machining hard-to-hold rings, discs and sleeves.
Radial pole division also achieves higher stability and rigidity, especially with larger diameters.
A central through-hole can be provided. The chucks are activated with a hexagonal switch lever.
Advantages
- Excellent for clamping rings
- Low overall height with very high holding force
- The clamping surface can be machined to a maximum depth of 8 mm
- Workpieces can be clamped quickly
- 10 mm penetration depth of the magnetic force
- Smooth on/off switching via the switch lever
- Liquid-tight
- The centre is non-magnetic and a through-hole can be provided
