An eccentric shaft becomes an eccentric when a circle does not rotate around its center. The eccentric shaft is also a kind of cam. Generally speaking, the main purpose of the eccentric wheel is to generate vibration. Like the electric screen, the vibrator in the mobile phone uses the eccentric wheel. Most of the eccentric wheels are round wheels, because the round wheels are easy to manufacture and the process is simple.

In the process planning and fixture design of eccentric shaft machining, we should adopt the method of combination of process centralization and process decentralization, and design an automatic production line according to the production batch and actual production situation. When the process is organized according to the principle of process concentration, efficient machine tools and process equipment with high degree of automation are also widely used. This greatly improves productivity.
