[0002] Stainless steel billet trimming refers to cutting or trimming the edge of the stainless steel billet through mechanical processing or manual operation to form a specified shape, size and surface quality. The main purpose of trimming is to remove uneven edges. After the billet is cast or forged, there may be burrs, protrusions or depressions on the edge. Trimming can remove these unevenness and make the billet edge flat and smooth.

[0003] Traditional stainless steel strip cold rolling blank trimming devices have some shortcomings, such as low automation and often rely on manual operation to move the steel strip blanks, which is not only inefficient, but also easily leads to insufficient cutting accuracy due to human factors, affecting product quality. In addition, traditional equipment also handles the waste generated during the trimming process in a relatively rough manner, usually simply allowing the waste to fall naturally or accumulate near the machine, which not only takes up valuable production space, but may also have an adverse impact on the working environment and may even cause safety hazards.
