The metal powder is partially oxidized, the sintering temperature is low, and part of the metal powder is not alloyed. As a result, the side wear of the diamond cutter head in Shandong has been caused. Today, how about the characteristics of the cutter head?
Sparks are severe when the cutter head is cutting. The strength of diamond is too poor, especially the strength of coarse-grained diamond. The cutter head is obviously high in the middle, low on both sides, or too high on both sides and too concave in the middle. In this case, the distribution of diamonds in each layer is uneven, and the difference in diamond concentration between inside and outside is too large. The edge diamond is too poor in quality and too low in strength. The edge layer diamond concentration is too low, and the fine-grained diamond content is too small; the matrix is not flat; the metal matrix is not matched, and the wear resistance is too poor.
