The development started in 1969, exactly 55 years ago — for the first time, General Electric, back then a manufacturer of super abrasives, offered Borazon as an abrasive for the development of so-called boron nitride CBN grinding wheels and pins to the abrasives industry. Borazon, advertised as abrasive of a new era, with its extraordinary hardness and heat-resistance made it possible to grind hardened steels, starting from 58 HRC, faster and more efficient than ever before.

Lach Diamant developed resin-bond Borazon CBN grinding wheels under the branding K-MX and tressex for the grinding of HSS and hardened steels were, from the very start, so successful that they quickly took the place of conventional ceramic wheels, e.g. for tool grinding. One grinding task was immediately taken over by Borazon — internal cylindrical grinding. Lach Diamant developed G-MX grinding pins and internal grinding wheels with electroplated bonds turned out to be an immediate success, especially for the manufacturers of collets.

To this day, Lach Diamant provides a large portfolio of Borazon CBN grinding pins and internal grinding wheels for all collet manufacturers, all immediately available from stock. Depending on the application, all internal abrasives — diamond and CBN — as well as all Lach Diamant produced grinding wheels can be delivered in special resin, metal and ceramic bonds.
