In all fields of metal processing magnetic clamping chucks can be used. Both very thin, damageable workpieces and huge, heavy parts can be safely fixed with the various types of magnetic clamping plates. Especially when processing small batches the use of magnetic chucks will pay off as a quick change of the workpieces/parts can be made. SPREITZER offers permanent magnetic chucks, electromagnetic chucks, electro-permanent magnetic chucks, magnetic round chucks – for every requirement the suitable clamping plate.
Advantages
- Clamping with short setup time
- Flexible and universal

Permanent magnetic plate SPMT
Permanent magnetic clamping plates type SPMT are of low height and are suitable for spark erosion and precision grinding of small and thin workpieces.
Magnetic sine plate SPNS
SPNS magnetic precision sine plate with built-in SPNM magnetic plate convince with very good workmanship and precision. The sine plate body is hardened to 60 HRC, burnished and precision ground. The angle is set according to the sine principle with the help of gauge blocks. Our SPNS sine plates are used for eroding, grinding and measuring with the highest precision. SPNSI precision sine plates swivel over the longitudinal axis up to an angle of 45°. SPNSIL precision sine plates swivel over the transverse axis up to an angle of 30°. SPNSID precision sine plates swivel up to 45° over the longitudinal axis and up to an angle of 30° over the transverse axis. SPNSM sine plates pivot about the central axis by ± 90°.
Magentic lamella plates
Magentic lamella plates are used together with magnetic clamping plates. If parts can only be clamped with great difficulty or not at all on a magnetic clamping plate due to very low material thickness, three-dimensional structure or poor magnetic properties, lamellar plates offer various additional options. Pins can be inserted and contours worked into lamellar plates, or they can be used as support surfaces, for example with T-shaped parts. Slat support plates are simply placed or screwed onto the magnetic chuck. Unless otherwise stated, our support plates are silver-hard soldered and can therefore be mechanically processed in any way.
Permanent Magnetic Clamping Plate SPNM
Permanent magnetic clamping plate type

Permanent magnetic clamping block SP-PMB
SP-PMB magnetic clamping blocks have four clamping sides and are switchable by the turning knob at the front side. They are universally usable for flat grinding, angular grinding, coordinate grinding, EDM, measuring, etc.. Due to the fine 2 + 2 mm pole pitch, thinnest pieces (from 0,5 mm) can be clamped safely; on the back there are 4 M5 threads for the attachment of stops. Because of the low magnetic field height of only 2 mm and the complete hermetic seal, SPM clamping blocks are particulary suited for the use with wire- and sparkerosion, SPM clamping blocks in a rust-resistant chrome steel design are available too.
