According to the problem of actual production of the crankshaft balance efficiency is low, with a total weight for at least the objective was proposed based on dynamic balance principle of quality of crankshaft centering system. The crankshaft multifaceted correction method was close to the crankshaft end face to dynamic balance measurement of mass, then according to the results, by using the influence coefficient method for mass centering the influence coefficient. The measured data was transfered to mass centering machine PC system, according to the system provided data, drilling center hole process was carried out. The results show that the quality of centering is succeeded in reducing the crankshaft to weight, realized the optimization of crankshaft manufacturing process, improved the crankshaft production efficiency and product qualification rate effectively, and reduced the crankshaft manufacturing cost.
