Professor Peter Krajnik, centrumföreståndare Chalmers MCR

(Professor of Manufacturing Technology, Director of Chalmers Centre for Metal Cutting Research (MCR); specialist in grinding technology – previously working at Scania CV AB in the area of engine component manufacturing, innovating grinding operations for camshafts and crankshafts)

Course summary:
The course on grinding with conventional abrasives and superabrasives. It is aimed at those who already have at least some experience in grinding and want to obtain an in-depth understanding of production grinding, namely in view of automotive and bearing applications.

Topics covered:
Grinding mechanisms • Conventional abrasives • superabrasives • specifying a wheel • choosing a grit size • thermal aspects • reducing burn • cooling • pressure vs. velocity vs. flowrate in cooling • nozzles • quality control and non-destructive testing • grinding parameters • how to choose speeds & feeds via “Aggressiveness” • finding the “sweet spot” of the wheel • cylindrical grinding, choosing speeds & feeds for cycle-time reduction & low temperatures • grinding of hardened steel • grinding vs. hard machining • chatter (vibrations) • single-point dressing • dressing parameters for wheel sharpness • rotary dressing • truing & conditioning of superabrasives (optionally)
