Vacuum brazing - Import export

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.

Heat Treatment furnaces MOV are ideal for the treatment of sophisticated materials if high temperatures and an absolutely clean hydro-carbon free atmosphere are required. Due to the ultrahigh vacuum atmosphere as well as the extreme temperature homogeneity and the fully automatic process the furnaces are especially suitable for the economic application in industrial and medical productions, i.e. for brazing of vacuum interruptors, parts of x ray tubes, heat exchangers, parts used in the medical and aerospace industry. Applications: MOV furnaces are universally applicable if heat treatment with particularly high requirements in respect of cleanliness for exacting materials is involved, for example: • Degassing of electric or radiation tube components • Bright- and stress-free annealing of high-temperature alloys • Sintering of high-melting and heavy metals such as tungsten • Production of high-quality fluxless braze joinings of steels, steel-ceramics and many other materials.
