Secondly, the adjustment method of traditional devices is relatively complicated and inconvenient to operate, which is not conducive to improving processing efficiency. With the rapid development of the modern automobile industry, the requirements for wheel processing accuracy and efficiency are getting higher and higher, and traditional fixing devices can no longer meet actual needs.
