In the WTH 200.2, the following materials can be reliably brazed with active materials in a high vacuum. PCD (polycrystalline diamond) MKD (monocrystalline diamond) CVD diamond (chemical vapour deposition) PCBN (cubic boron nitride) and Hard metals as well Ceramics In the high-vacuum furnace WTH 200.2, our customers manufacture indexable inserts, dressing wheels, rotating tools and turning tools with blades made of natural diamond or MKD for polish turning. The vacuum brazing is flux-free. In the so-called active brazing process, titanium allows wetting of the surfaces. While cemented hard metals can also be inductively brazed, diamonds, CVD and ceramics must be actively brazed in a vacuum. When brazing PCD and PCBN, not only the hard metal substrate but also the PCD or PCBN layers are wetted.

Continuous generating grinding is one of the most productive technologies to grind high precision gear tooth flanks. KAPP manufactures dressing tools in positive and negative electroplated version. Highest flexibility can be achieved with form rolls for topological dressing. For the so called “flexible dressing” the tools are designed to dress worms for different workpieces with one tool, while the tip of the worm is dressed separately. For serial production there are profile rolls with integrated tip dresser in a workpiece specific manner also for grinding of well defined gear root area. Most productive for high volume are multi-ribbed diamond profile rolls made in a negative electroplating process.
