When a crank or cam is polished on one of these machines, it uses about one inch of tape per journal, so fresh abrasive is used for every polishing job, but because it's such a small amount, many users say they've saved money. "One PER reported a 50-75 percent savings in the cost of tape vs. belts," Barton says.

اقرأ أكثرGrinding wheels have two major components: the abrasive grains and the bond. The relative percentages of grain and bond, and their spacing on the wheel, determine the wheel's structure. Different types of grains work better on different projects, as do different types and "grades" (i.e. strengths) of bond.

اقرأ أكثرThe main reason crankshaft grinding is done is because the crank wears over time. Over thousands miles the end play between the crankshaft and the bearings increases. When the "fit" between the bearings and the crank isn't perfect it lowers oil pressure and decreases lubricity. The less oil to the crank the faster it can wear out.
