Magnetic Chuck EPFlux

For over 30 years, Assfalg is characterized by continuous improvements in magnetic clamping technology. The EPFlux magnetic chuck is now a unique innovation that has been reached through a cooperation with leading machine manufacturers.

The electropermanent magnetic chuck EPFlux is the appropriate chuck for precision grinding machines. The EPFlux magnetic clamping plate shows no remanence (residual magnetism) when deactivating.

High-alloyed and hardened workpieces can be easily detached from the magnetic chuck. Highest grinding accuracy is achieved because no heating of the plate takes place.

ADVANTAGES

  • Clamping force approx. 100 N/cm²
  • Pole pitch 5 + 1,5 mm
  • Incorporating cable outlet
  • Controlling and switching with the controller D50-F/D100-F 220 V / 400 V depending on the size of the chuck

Application

The electropermanent magnetic chuck EPFlux is the appropriate chuck for precision grinding machines. The laminated made of brass and steel surface of EPFlux magnetic clamping chuck and the solid steel body guarantee both a magnetic holding force over the entire surface as well as a unique rigidity.

With the EPFlux magnetic chuck all sizes of workpieces with different surfaces can be clamped evenly. Activating and deactivating (magnetizing and demagnetizing) takes place by a short current pulse within seconds.

The EPFlux magnetic clamping plate shows no remanence (residual magnetism) when deactivating (Demagnetization). Highest grinding accuracy is achieved because no heating of the plate takes place. No heating means that there are no dilations and deformations of the workpieces to be machined.

This magnetic chuck can be easily mounted on the machine table by attaching through holes.

Economy

The EPFlux magnetic clamping chuck shows no remanence (residual magnetism) when deactivating (demagnetization). Therefore, high-alloyed and hardened workpieces can be easily detached from the magnetic chuck. Highest grinding accuracy is achieved because no heating of the plate takes place. No heating means that there are no expansions / dilations and deformations of the workpieces to be machined.

With the EPFlux magnetic chuck all sizes of workpieces with different surfaces can be clamped evenly. Activating and deactivating (magnetizing and demagnetizing) takes place by a short current pulse within seconds.

The laminated made of brass and steel surface of EPFlux magnetic clamping chuck and the solid steel body guarantee both a magnetic holding force over the entire surface as well as a unique rigidity. The EPFlux magnetic chuck has a long-lasting stability and no maintenance is necessary.

Safety

Electropermanent magnets combine both the electrical and the permanent magnet technology. The EPFlux magnetic chuck is like a permanent magnet which is electrically switched on and off. Electropermanent magnets are characterized by a strong adhesive force that they do not lose in the event of power failure.

The electropermanent technology guarantees maximum safety, because only a current pulse is necessary to clamp. Holding the workpiece on the magnetic clamping plate takes place with re-poled permanent magnets. During clamping phase, no current flows.

In the event of a power failure or a cable break of the control line, the workpiece remains clamped at full adhesion to the EPFlux magnetic chuck. The EPFlux magnetic clamping plate shows no remanence (residual magnetism) when deactivating (demagnetization). The magnetic field can be reduced by an adhesive force regulation.
