1950 – Today
A proven wire honing Process!
As with many other Swiss inventions, the origin of the wire-DSM process is to be found in the watch industry. It has been used since the early fifties to super-finish the inner diameter of watch bearings made from ruby. Numerous other industrial sectors have since benefited from this highly reliable and accurate process.
