Precision tool manufacturing
Manufacturers of precision tools for wood, plastics or metal machining place very exacting demands in terms of metallurgical features and machinability. Two essential criteria are minimum dimensions and dimensional accuracy of semi-finished products and blanks.
Forming industry
The selection of the carbide grade is especially important for this production sector, because worn or premature failure in tooling results in production stops which are costly. The choice out of more than 40 grades - from submicron grain carbides with 3 % cobalt to the course grained 26 % cobalt grade - enables Boehlerit to find the ideal solution for customers´ applications.
Tool making
Years of close cooperation with our customers have put us in a position today to be able to offer the right carbide grade for every application.As sintered blocks as well as semi finished products are produced with or without wire start holes and according to customer drawings. All Boehlerit tungsten carbide grades which are used in this field are sinter-hipped where by a regular and pore-free structure is obtained.
Wood processing
The majority of grades found within this sector are made up of fine, submicron and ultrafine grain carbides with between 2 - 6 % cobalt. Special value is placed on the even grain distribution, where the benefits of fine grain material come in to being. Boehlerit fine grain carbides distinguish themselves through a high degree of cutting edge stability combined with good quality transverse rupture strength and reduced wear tendencies.
Construction industry
Boehlerit has been designing and manufacturing tungsten carbide tooling for the “Roof Tile“ and “Clay Industry“ for over thirty years and is recognised for being one of the pioneers within this complex technology. When compared to steel, our tungsten carbide tooling achieves between a twenty to thirty fold increase in tool life.
Specific industries
Recent years have seen a marked increase in the use of carbides as construction components. The demand for a material that offers the highest possible level of reliability in highly diverse conditions comes from a wide range of industries, such as the chemical industry, plastics manufacturing, the food industry, oil and gas production, beam technology, the recycling industry and also the health and hygiene sector.
Agricultural engineering
Boehlerit, Austrian carbide specialists with a long tradition, have invested a great deal of technical know-how in recent years into developing a customer-focussed and demand-orientated tools for soil cultivation.
Carbide raw material
The blanks are then dewaxed and presintered at temperatures of between 700°C - 800°C in order to achieve the strength condition needed for the final processing. The presintered blocks are processed largely on CNC machines using diamond or PCD cutting tools and given the form demanded by the customer.
