- Pole division
- Radial pole
- Application
- Turning, milling
Description
Compared with chucks with parallel or square 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 in the area without active magnets.
The EPRadial electro-permanent magnetic chuck is ideal for distortion-free clamping of large, rotationally symmetrical workpieces (for example in bearing ring machining) from a diameter of 400 mm, in particular on turning and milling machines as well as on drilling machines.
EPRadial allows extremely high stock removal in the hard machining of rings, and the highest precision is achieved in grinding.
Fixed and mobile pole extensions can be mounted on the pole strips with T-slots. Pole extensions allow uneven workpieces or raw parts to be clamped without distortion as well. The workpiece is clamped in a raised position and can be machined without damaging the magnetic chuck.
A special cable with bayonet connector or a fixed cable with slip ring carrier allows quick and simple connection of the magnetic chuck to the control unit.
Advantages
- Extremely short set-up times thanks to simple and fast clamping of workpieces
- 3-sided machining, as only one side of the workpiece is needed for magnetic clamping
- Distortion-free holding of raw parts or uneven workpieces thanks to form-fit clamping with fixed and mobile pole extensions – shimming of workpieces is no longer necessary
- No damage to the magnetic chuck in the event of breakouts, as the workpiece can be clamped raised on pole extensions
- Easy adjustment of the magnetic holding force for thin workpieces or for alignment, via the holding force regulation
- Extremely high, permanent magnetic holding forces, activated within seconds
- The centre of the chuck is non-magnetic and a through-hole can be provided
