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)
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.
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)
