Cast and Forged Pistons
As with a crankshaft though, the forging process gives us a part that is much denser with greater ductility than a cast piece. All cast pistons contain a certain amount of silicon, generally 10-12 percent, the amount of which is known as the "eutectic point.". Changes to the aluminum alloy can, however, produce stronger cast parts better ...Web

Cam grinding is one of the more complex grinding operations. This is because of the cam's geometry.
