Grinding of Metals: Origin and Cutting Action | Industries ...
14. Thermal Effects of Grinding: During the process of grinding a lot of heat is generated between the cutting tool and workpiece. A major portion of the heat is dissipated in the workpiece and the remaining is retained by the grinding wheel. Two thermal effects of grinding are: 1. Effect on Grinding Wheel:
Whirling Machine Series - Part One - Leistritz
Precision in One Operation. Modern whirling processes produce helical geometries in just one step – without subsequent grinding or polishing. Heat generated through cutting is largely dissipated with the chips, so the workpiece does not get so hot and change the surface properties of the material – a crucial requirement with hardened parts.
