Grinding burn

Bearings, gears, shafts and many other surface hardened components, in modern automotive and aerospace industries, form a challenge to design and production engineers. They require special attention in choosing the correct parameters for the heat treatment as well as for the subsequent machining processes.
The latter, if carried out inaccurately, may reduce the surface hardness and diminish the favorable compressive surface stresses after surface hardening.

Accurate and continuous control of machining processes such as grinding or hard turning is essential in today's production control. Innogrind delivers an inspection method based on the Barkhausen Noise Analysis (BNA) which is capable of 100% in-line control of grinding burn.

This method has been shown to be more sensitive than the conventional Nital etch inspection and also superior to the alternative method using eddy current.

•	The early detection of defects in your product before it is rejected
•	It is a non-destructive testing methode
•	Early detection of changes in microstructure and hardness
•	By using Viewscan software its easy to visualize the process.
