• TIG welding

  The tungsten inert gas welding (IG welding) belongs to the group of melt welding processes and is characterized by particularly clean processing, high seam qualities and almost universal applicability in the metal sector. Due to the particularly precise tuning of the welding current to the respective welding task, the welding method is particularly suitable for root positions and forced positions. For this reason, WIG welding enjoys great popularity in tasks with high standards of precision and seam quality, such as pipeline and apparatus construction, power plant construction and chemical industry.

• Tool making

  In the case of tool construction, high-precision tools are produced which serve to produce workpieces in mass production. The tools must be made of a suitable material and produced in the highest quality. Most manufacturers of such tools work in the machine park with modern CNC machine tools, by means of which precise and detailed contours can be realized. In this case, the production technology is frequently chosen to mill in order to machine a workpiece from which the finished tool emerges.

• Trowalizing

  The trolling is also referred to as sliding grinding or sliding cutting and is a separating method of surface machining. In this case, metal workpieces together with a grinding means are usually introduced into a rotating drum in order to remove material in a targeted manner. Trowalization is described in the DIN 8589 standard, together with the lapping and polishing, and is referred to as sliding panels. The process is very popular in the metal processing industry, as it can perform several tasks from and rounding over smoothing and polishing to matting and grinding. The desired result of the surface treatment can be brought about in a targeted manner by the variation of the machines and grinding means used.

• Turning

  The turning is one of the most important cutting methods and is used to manufacture cylindrical components. A single-edged tool (e.g. a rotary chisel made of high-speed steel) is guided to a rotating component in order to remove successive chips and to achieve the desired geometric shape.
