[0002] Channel steel is a long steel strip with a grooved cross section. It is mainly used in building structures, curtain wall projects, mechanical equipment and vehicle manufacturing. After production, channel steel is cut into strips. However, there are burrs and sharp corners on the cut edges, which makes it difficult to assemble and easy to crack. The cut edges need to be chamfered. High precision is required during chamfering. Accurate chamfering can only be achieved after accurate positioning. Manual grinding is cumbersome, wastes manpower and has low efficiency.
