Precision solutions and quality grinding

Mechanical and plant engineering

Do you require µ-precision grinding of your high-grade cutting knife? So that only the material that needs to be removed is removed? Do you want your circular knife to be ground with a precision surface-grinding machine from Jung that uses a free-rotating rotary table? Then you've come to the right place!


Trauwert GmbH: Our three cutting-edge divisions
Surface and profile grinding in the contract manufacturing sector ❯

In contract manufacturing, Trauwert GmbH also µ-precision surface and profile grinding of slide and roller guides. Among other things, this includes µ-precision grinding of the clamping jaws into the chuck body (slide guide) or sharpening circular knives with diameters of up to 400 millimetres, which are required, for example, for cutting hydraulic hoses.

The manufacture of cutting punches along with the production of cutting and embossing tools for moulds and special machine assemblies are also part of the contract manufacturing sector. With a maximum of 600 x 300 millimetres, our machines offer a considerably large grinding area.

Retrofitting and refurbishing mechanical assemblies ❯

Whether it’s a Diaform head dresser, Jung-PA37K head dresser or Jung-PA130T table dresser: Trauwert GmbH restores dressers to factory-fresh condition. Overhauling the mechanical assemblies ensures sustainability and avoids expensive new acquisitions. Application areas for these assemblies are the 100 percent mechanical profiling of grinding wheels as well as the automatic profiling of grinding wheels using freely programmable CNC control technology.
