The dawn of a new age of cutting technology – from a natural diamond cutting company to the pioneer of polycrystalline diamond and CBN tooling

A spark which ignited a technical revolution – and made Horst Lach the inventor of spark erosion for the machining of polycrystalline cutting materials.
It was only this little spark that brought the cutting world to its current glory…
Luck and success in the years of decisions – new beginnings
