Abrasive wheels that withstand thermal shock are very important when grinding fine parts that are prone to the damaging effects of heat and mechanical temperature changes. They are made of ceramics or composite materials, capable of withstanding thermal shock abrasives uh wheels. Cracking due to thermal cracking because of heat during grinding and sudden change like spraying coolant will most certainly fail the system. Unlike other wheels, thermal shock resistant abrasive wheels can withstand the drastic temperature changes, permitting efficient grinding without sacrificing accuracy. Because of the high precision operated super alloys in the aerospace sector, they withstand high temperatures and stress, these wheels have gained particular preference.
