1. V-shaped guide rail rack is equipped with bearing roller, which has the characteristics of long service life, fast reaction speed and low environmental requirements.

2. Difficulties in processing, the dimensional accuracy between the V-shaped surface of the guide rail and the drive gear cannot be guaranteed.

3. Research content, through the optimization of the process route, coupled with the corresponding fixtures, to achieve the processing of the rack guide rail, complete the self-supply of the rack guide rail, and put it to the market.
