Electronic Polarity-Reversing control unit

Compared with conventional mechanical or hydraulic solutions like acial clamping or 3-jaw chucks with pendulum jaws, the magnetice clamping system is a preferable alternative. It leads to tolerance reductions of up to 85% on surface quality, cylindricality and thickness of e.g bearing rings. Sav has developed special magnetic systems for hard-turning to supply the strong holding forces as required for hardened materials.
