· The crankshaft is then set to spinning at a very slow speed. The grinding stone in the back is then spun up to speed and is then brought into contact with the journal face. As material is removed through the grinding process the machinist pays attention to how much is removed then stops the process once just shy of the finished dimensions.

Analysis of Grinding Strategies Applied to Crankshaft
· Improvements in the crankshaft grinding operation can be achieved by combining new grinding strategies and high performance CBN grinding wheels. The adoption of high speed CBN face grinding with axial feed in place of plunge grinding enables grinding of different workpiece widths using a single fixture thereby increasing the process flexibility 2 .
