Processing (1) difficult to process non-ferrous materials
When the processing of copper, zinc, aluminum and other nonferrous metals and alloys, materials, easy to adhere to the tool, processing difficulties. Using diamond low coefficient of friction and non-ferrous metal affinity characteristics of small, diamond tools and cutting tools can effectively prevent the occurrence of metal bonding. In addition, since diamond elastic modulus, when the cutting edge portion distortion, for the cutting of non-ferrous metal extrusion deformation is small, the cutting process can be completed in under small deformation, which can improve the surface quality.
(2) difficult to process non-metallic materials
Processing particle contains a lot of high hardness hard non-metallic materials, such as glass fiber reinforced plastic, filled silicon material, hard carbon fiber / epoxy composites when hard particles of materials to make the tool wear serious, hard carbide cutting tools processing, while the diamond cutter high hardness, wear resistance, and therefore high processing efficiency.
(3) ultra-precision machining
With the advent of modern integrated technology, high-precision machining to develop in the direction of the tool performance made considerable demands. Because diamond friction coefficient, low thermal expansion coefficient, high thermal conductivity, can cut very thin chips, chip easily flows with little affinity for other substances, easy BUE, heat a small, high thermal conductivity, heat can be avoided on edge and the workpiece, and therefore blade easily passivated, small cutting deformation, the surface of higher quality can be obtained.
