WIGTEC FISCHEREDER KG

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.

The vacuum technology is divided into the areas of measurement, generation and maintenance of a vacuum and the resulting technical applications. Vacuum technology is used in various fields of research and industry, for example in the handling and treatment of materials, in food and medical technology. Benefit from our many years of expertise in the conception and implementation of innovative and high-quality solutions in the field of vacuum technology components and plants.

The use of components in processing equipment, production facilities or transport containers in food technology is subject to the regulations for so-called food contact materials. For example, the use of food contact materials in compliance with EU legislation must ensure that the composition, taste and odour of the food is not compromised.

The requirements placed on components in the medical sector are extremely stringent, since, for example, the welds, in addition to the technical quality, must also meet the highest demands in terms of optics. For example, we produce stainless steel slideways for the slip rings of computer tomographs. We were also able to support our customers here in choosing the materials and the definition of the welded joint.
