Fig. 2 Large gear that cracked during grinding operations. Localized thermal gradients during grinding resulted in high residual stresses and eventual cracking. Temper etching (dilute nitric acid in water) revealed the presence of abusive grinding. Overview of the Mechanisms of Failure in Heat Treated Steel Components / 45Reduction of the speed leads to a decreased fine fraction of the sample and to more particles within the desired size range. Especially for this type of application, the lowest speed of the SM 300 was reduced to 100 min-1.This is also beneficial for grinding heat-sensitive materials: reduced speed results in less energy input, preventing the sample from getting too warm during the process.

Cryogenic Grinding abstract Cryogenic grinding permits heat-sensitive, thermoplastic, and elastic materials to be economically ground to very small particle sizes. The cryogenic process actually embrittle a material prior to size reduction and controls heat buildup in the grinding equipment. The result is high product quality and system productivity.This procedure is also used in applications that require secondary operations, such as deburring, applications with fragile materials, and applications that use heat sensitive materials. Electrochemical Grinding (ECG) is the ultimate method to provide exacting tolerances without developing residual stresses or microstructural damage.
