US6767273B1 - Crankpin grinding method - Google Patents

A method is described for grinding a crankpin of a crankshaft using computer controlled wheelfeed and headstock drives ( 44,30,24 ). During a final grinding step leading to finish size the cutting force is maintained on the wheelhead ( 38 ) to keep the wheel ( 34 ) and pin under a moderate constant load and the rotational speed of the headstock drive ( 24 ) is reduced.

Modern crankshaft machining methods - High Power

The traditional method of rough-machining the crankshaft was to turn each crankpin on a large sturdy lathe with the crankpin on centre and the central axis of the crankshaft offset by half of the crank stroke. The forces involved were considerable, and the machining was time-consuming. The advent of modern machining inserts has improved things, but these types of tools are often not forgiving ...
