Compared with the traditional passenger cars engine vibration pulleys, light diesel passenge
3、r cars pulley can meet in the family cars, but also for large passenger cars, large trucks, agricultural vehicle engine. It has many advantages, such as recycling, lighting weight, enhanced engine power and reduce fuel consumption, etc. In this regard, the pulley uses mechanical method, so as to ach
4、ieve the purpose of directly changing the parts of the size, shape and surface quality, it is called machining process to make it part of the process. In machining process, Jig is used to hold the work object, so that it occupies the correct position for receiving the processing or detection means.
