Due to the physical properties of single crystal diamond itself, it is not easy to stick knife and produce built-up edge when cutting, the surface quality is good. When non-ferrous metal is processed, the surface roughness can reach Rz0.1 ~ 0.05μm. Diamond is also effective in processing non-ferrous and non-ferrous materials such as non-ferrous metals such as copper and aluminum and their alloys, ceramics, cemented carbide, various fibers and particle reinforced composites, plastics, rubbers, graphite, glass And all kinds of wear-resistant wood (especially solid wood and plywood, MDF and other composite materials).
