BILLET

CRANKSHAFT

A crankshaft is a part which receives bent vibration and twisted vibration by explosive pressure and return inertia force, therefore a crankshaft should keep its strength for corresponding these conditions. This matter should be especially needed in the tuned engine with high power. But improvement of strength becomes to decrease response of engine if to add more fat without consideration. Both strength and lightness are realized by performing stress analysis. SCM440 is used as a material and processing corresponding to the material is performed. It has both strength and lightness by giving heat treatment and a special surface treatment.

In order to rotate a crankshaft smoothly, the accuracy (The degree of a true circle, and surface roughness) of a pin journal becomes important. The crankshaft which polish finished pays careful attention to the degree of a true circle, the surface roughness, and transformation, etc.

After the finishing surface treatment, friction loss is at a minimum. Bent or out of balance crankshafts due to bad manufacturing will cause severe vibrations even with excellent counter weight balancing. Therefore Dynamic balance adjustment and bend correction are performed to eliminate as much vibration as possible.
