The standard series of Super-EPM chucks include more versions which have different performance characteristics. Capable of adapting to different operating needs, depending on the thickness. The surface condition (or the operating air gap) and the dimensions of the work piece to be clamped. The clamping force of each version depends on the different dimension types of poles and on the configurations of the magnetic area.
Each pair of N/S poles generates an autonomous and defined force which is not influenced by the operating conditions of the other adjacent poles. Therefore by counting the number of poles occupied by the clamped piece it is possible to predetermine the force generated and consequently to establish the usable machine power with 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 a pair of size 75 poles (75*75mm) can go up to 4 kw
