Selecting the right solution

The standard series of Super-EPM chucks include more versions whichhave different performance characteristics. Capable of adapting todifferent operating needs, depending on the thickness. The surfacecondition (or the operating air gap) and the dimensions of the workpiece to be clamped. The clamping force of each version depends onthe different dimension types of poles and on the configurations ofthe magnetic area.
Each pair of N/S poles generates an autonomous and defined forcewhich is not influenced by the operating conditions of the otheradjacent poles. Therefore by counting the number of poles occupiedby the clamped piece it is possible to predetermine the forcegenerated and consequently to establish the usable machine powerwith the relative machining parameters.
As an indication we can say that a pair of size 50 poles (50*50mm)can enable processing of up to 2 kw machine absorption, while apair of size 75 poles (75*75mm) can go up to 4 kw

EPM50
Version with a standard polar density comprising size 50 poles witha force of 380 kgf for each pole.
Extremely useful for clamping work piece of all sizes. Also withlimited thicknesses and normal operating air gaps.
