abstract:
A planer comprises a white iron matrix and a steel-inlaid layer at the edge, and at least a part of the outer surface of the white iron matrix is a fine grained surface. The fine grained surface is a sandblasted surface, and the surface inlaid with steel layer is a smooth surface. The surface of white iron matrix is gray after sandblasting and fine grained surface treatment, while the surface brightness of inlaid steel layer is better. It is convenient to distinguish whether there is a lack of steel inlay, which is beneficial to test the quality of products. At the same time, the burr at the corner of the planer can also be knocked off, which is beneficial to packaging.
