模具磨刃口在生产中是常见的工作,但是往往在磨加工中出现多种形状的裂纹:有直条状、网状(鱼鳞状)、纤维状及波浪状等。裂纹的深度、长度、数量分布不—。有的裂纹深度可达1.0毫米;裂纹长度有的2～15毫米,有的贯穿整个平面:有的裂纹分布整个被磨平面。磨削裂纹的产生,不仅降低模具 Mold grinding edge is common in the production of work, but often appear in the grinding process a variety of shapes of cracks: a straight strip, mesh (fish scale), fibrous and wavy and so on. Crack depth, length, the number of distribution is not -. Some crack depth up to 1.0 mm; crack length of 2 to 15 mm, and some throughout the plane: some crack distribution throughout the plane to be polished. Grinding cracks, not only reduce the mold
