Grinding determines the size, and honing improves the shape. The difference between honing and grinding is always same. Some grinders have complex movements and are selftruing, and some honing machines are equipped with inprocess gauging for size control. Many throughfeed grinding operations rely on the same averaging effect as honing.

The obvious source of forces applied to a crankshaft is the product of combustion chamber pressure acting on the top of the piston. Highperformance, normallyaspirated Sparkignition (SI) engines can have combustion pressures in the 100bar neighbourhood (1450 psi), while contemporary highperformance CompressionIgnition (CI) engines can see combustion pressures in excess of 200 bar (2900 psi).
RAW GRINDING : The raw materials are very finely ground in order to produce the raw mix. 1. RAW GRINDING Raw grinding and burning 2. BURNING 2.
