Before this acquisition its services already included nickel and hard chrome plating, machining, grinding and honing.
Classic machines have a 25 kg wire spool capacity to enable long, unattended EDM machining operations to be undertaken.
The toothed wheels give a slightly better efficiency, but the worm gear is somewhat smoother in its action and entirely silent; the noise of gearing can, however, be considerably reduced by careful machining of the teeth, as is now always done, and also by the use of pinions made of rawhide leather or other non-resonant material.
