Ravitex® cutter RX PATENT EP 2193003

RX CUTTERS PATENT EP2193003

Industrialized and commercialized at the end of 2010, the three-blades hard metal RX cutters patent EP2193003 manufactured by SINTERLEGHE allow to:

Double electrode’s life reducing their costs as well as any other costs incurred for poduction line stops needed for their replacement. Needed for replacement
Dress electrodes of different shapes or special electrodes with one single model of cutter
n the 120° version improve the cooling of the electrodes to prevent the decay of their chemical and mechanical properties
Have a vibration-free cutter that can completely clean the electrode through a single dressing cycle.
Keep a constant removal from electrodes by the cutter according to the variation of the closing force of the welding gun and electrode’s hardness
Reduce costs of spare cutters, reduce replacement and maintenance frequency thanks to the high durability of the hard metal blades
Be used on different brands of dressers

For inquiries about cutterm, if the electrodes do not correspond to ISO 5821 B-E-F-G, send the drawings of the welding gun and of the electrodes in one of the following formats: step, igs, xt, sat, catpart, dwg, dxf.
