Permamax Round Magnetic Chuck
The permanent magnetic chuck Permamax of Assfalg is a very strong round chuck with neodymium magnet system and parallel pole pitch. It is manually switched.
Thin and small workpieces can be clamped, in particular for grinding and turning of thin disks and rings.
ADVANTAGES
- Medium design height with very high adhesive force
- Processing of adhesive surface up to max. 8 mm depth (5 mm at D ≤ 130 mm)
- Liquid-tight
- Mechanically switchable
- Workpieces can be clamped stress-free and fast
- All-around processing as only one side is clamped magnetically
- Low penetration depth of the magnetic force (approx. 10 mm) because of the flat magnetic field
- Adhesive force: 140 N/cm² with pole pitch 12 + 3 mm
Application
Permanent magnetic round chuck Permamax with neodymium magnet system and fine pole pitch are used for clamping of thin and small workpieces, especially for flat grinding and internal cylindrical grinding, turning and hard turning of thin disks and rings. The magnetic force is controlled steplessly.
Magnetizing and demagnetizing is carried out manually via a lever. Centering grooves that are incorporated in the surface facilitate the alignment of the workpiece. A centering hole can be incorporated into the clamping surface.
A processing of the adhesive surface up. 8 mm depth is possible. Since only one side is clamped magnetically, all-around processing is possible.

Economy
The permanent magnetic chuck Permamax has a medium design height with a very high adhesive force. In the surface, a central centering hole can be incorporated.
Since only one side is clamped magnetically, all-around processing is possible.
Safety
The adhesive force with the permanent magnetic chuck Permamax is infinitely variable. The workpiece can be obtained by centering grooves, which are incorporated into the surface, can be easily aligned.
Moreover, it is liquid-tight and can be mechanically switched on and off. Since the magnetic field is flat, the magnetic force penetrates only about 10 mm. The adhesive force is 140 N / cm² with a pole pitch of 12 + 3 mm.
