At the Hannover spring trade fair in 1969, Lach Diamant demonstrated the grinding of HSS and high-alloy steel on a tool-grinding machine.
In 1969, Lach Diamant introduced the first CBN grinding wheel for the dry grinding of an HSS (high-speed steel) milling cutter. The manufacturer claims to be first manufacturer worldwide to demonstrate the grinding of HSS and high-alloy steel on a tool grinding machine, much to the amazement of experts.
Lach Diamant's grinding wheels, first known as Borazon, was a trademark of General Electrics, which was then a manufacturer of super-abrasives, namely K-MX for resinoid bonds and Bz-Mx for metal bonds.
Today, 50 years after Borazon premiered as the abrasive of a new era, Lach Diamant offers its metal-bond profile grinding wheel, ‘contour-profiled’, which, it says, saves time and costs in the production grinding of high-alloyed steel, when it comes to profiles.
The company has now also developed a special electrical discharge profiling machine for regrinding — even for the most precise concave and convex profiles ranges of 2-4 µ.
