Compensating for Thermal Expansion in Precision Grinding
If left unaccounted for, thermal expansion can have a serious impact on the performance of any complex machine. In precision grinding, friction will inevitably add heat to the component undergoing the grinding procedure. As a result, the part will expand, which can throw off the final tolerance measurements.

Cooling during grinding – grindaix
Heat is generated due to the friction between the grinding wheel and the part as well as during removal of chips from the part. This heat presents a major challenge during grinding, as it can lead in the worst case to part damage (e.g. grinding burn) and thus to scrap, as the part can no longer fulfil its load requirements.
