Vacuum Technology

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.

New employees are first introduced to TIG welding in a basic training lasting several months. Only then are the first products manufactured for customers, whereby the following topics are handled in a multi-year development process, which includes the welding test for the tube welder CrNi relatively early: Material requisition Additional materials Gas protection Interpass temperature and welding temperature Maximum material temperature during welding Cleaning the weld seam Welding distortion Mechanical seam load

We provide you with many years of practical experience and innovative solutions from the initial idea through conception and planning to the development and production of your components. We focus on your individual requirements and ideas when it comes to different problems in component design: Welding distortion Processing of the component Weldability of the component Material selection Cost-effective implementation
