Hard machining – The best tools for hardened steels
Hard machining is playing an increasingly important role, especially in tool and mold making, in order to replace time-consuming processes such as grinding or eroding. The latest tool technologies and processes offer great potential in the field of hard machining.

Hardness testing and hardness testers
By hardening a material, the microstructure can be specifically changed in order to achieve greater mechanical resistance. Even a small increase in the hardness value has an enormous effect on the effect of action of the respective machining tools.
With the stationary and mobile hardness testers from HAHN+KOLB, you can precisely determine the hardness of your workpiece!
