Description

[0002] After the inner body of the hydraulic cylinder is produced, its outer surface has many lines. The inner and outer bodies need to move relative to each other, so there are higher requirements for the inner body, which needs to have a very smooth surface so that the hydraulic cylinder can have a better effect when used. Therefore, it needs to be polished. A polishing device is used during polishing, so a polishing device for the inner body of the hydraulic cylinder needs to be set up.

[0003] When using the polishing device for the inner cylinder body of the hydraulic oil cylinder, the polishing device in the prior art generally performs polishing directly during polishing. Sometimes, there may be some impurities, stains, rust, etc. on the surface of the inner cylinder body, which will slow down the polishing time and harden the polishing process.
