Machining of CNC eccentric shaft parts is One of the difficult parts to machine. Compared with the ordinary shaft, the Machining of CNC eccentric shaft parts is more difficult than the ordinary parts. The machining of eccentric shaft, especially the machining of slender eccentric shaft,It can reflect the processing capacity of an enterprise. With the development of science and technology With the development of technology, there are more and more requirements for the Machining of CNC eccentric shaft parts, and the precision is also higher and higher, so its application prospect is broad. CNC eccentric shaft machining is one of the common typical parts. According to different structural forms of shaft parts, they can generally be divided into light parts Shaft eccentricity, stepped shaft eccentricity and special-shaped eccentric shaft; Or divided into solid eccentric shaft, hollow eccentric shaft, etc. They In the machine, it is also used to support transmission parts such as gears and pulleys to transmit torque or motion.
