Magnaslot - Magnetic Chuck

The patent applies the "full steel surface" of this EPM magnetic chuck. Compared to conventional chucks with epoxy resin, our magnetic clamping chucks with a solid steel surface are more resistant against hot chips, coolants and other processing conditions. Through the use of pole extensions unevenness of the workpiece can be balanced and the deformation of the workpiece can be prevented.

This protects your milling spindle as well as your tools, increases process accuracy and extends the tool life. The homogenous magnetic field of the MAGNASLOT guarantees low vibrate clamping of the work-piece. This protects your milling spindle as well as your tools and increases the tool-life.

Uneven work-pieces can be clamped easily with the aid of optional pole-extensions onto the EPM-chuck, without delay. MAGNASLOT magnetic-chucks have a patented solid steel surface which offers protection from damaging hot chips and cooling liquids. Workpieces are clamped in seconds.

The electro permanent technology of the magnetic chuck with square-poles, guarantees highest possible safety, since only one current pulse is necessary for clamping,Holding the workpiece on the magnetic chuck is achieved through reverse polarising permanent magnets.

The workpiece is held with full clamping force by the MAGNASLOT EP-Magnetic chuck in case of an electricity failure or cable break. Accidental release of the work-piece, resultant of faulty operation, can be excluded due to the two-button-control, on the magnetic chuck and its controller.
ASSFALG solely sells magnetic chucks with a maximum of poles on the patented solid-steel surface of the magnetic chuck. Only this guarantees a maximum in clamping force.

In addition, manufacturing and process accuracy with plane parallelism of 0,02 mm and more can be achieved. With achieved clamping forces of 350 kg per square-pole 50x50 mm, a magnetic chuck with 400x600 mm in dimensions, reaches a clamping force of close to 17 tons.
