(1) Processing of non-ferrous metal materials that are difficult to process
When processing copper, zinc, aluminum and other non-ferrous metals and their alloys, the materials are easy to adhere to the tool and the processing is difficult. Using the characteristics of low friction coefficient of diamond and low affinity with non-ferrous metals, diamond cutting tools can effectively prevent metal and cutting tools from bonding. In addition, due to the large elastic modulus of diamond, the edge deformation is small during cutting, and the extrusion deformation of the cut non-ferrous metal is small, so that the cutting process can be completed under small deformation, thereby improving the quality of the processed surface.
(2) Processing of non-metallic materials that are difficult to process
When processing difficult-to-process non-metallic materials containing a large number of high-hardness points, such as glass fiber reinforced plastics, silicon-filled materials, hard carbon fiber/epoxy composite materials, the hard points of the material cause severe tool wear, which is difficult to use with cemented carbide tools Processing, and the diamond tool has high hardness and good wear resistance, so the processing efficiency is high.
(3) Ultra-precision machining
With the advent of modern integrated technology, machining is developing in the direction of high precision, which puts forward very high requirements on tool performance. Due to the small friction coefficient, low thermal expansion coefficient, and high thermal conductivity of diamond, it can cut extremely thin chips, the chips are easy to flow out, have low affinity with other materials, are not easy to generate built-up edge, generate small heat, and have high thermal conductivity, which can avoid heat The effect on the cutting edge and the workpiece, so the cutting edge is not easy to be dull, the cutting deformation is small, and a higher quality surface can be obtained.
(4) Particleboard woodworking processing
For large-scale woodworking cutting operations, especially for high-density, high-hardness and difficult-to-process sheet materials such as particleboard, density board, and anti-folder board, the cutting performance of traditional cemented carbide saw blades is difficult to meet. PCD composite diamond saw blade has become the cutting tool of the hardest material, and it has become the leader of woodworking dry cutting tools. Its super-hard performance and durability are the nemesis of woodworking materials. Diamond saw blades have a Vickers hardness of 10000HV and strong acid resistance. , The cutting edge is not easy to passivation, and the processed wood has good quality at one time and high wear resistance. Compared with cemented carbide, it is more wear-resistant. The continuous operation time for chipboard, MDF, wood floor, veneer and other cutting processing can reach 300~400 Hours, the maximum useable scrap time can reach 4000 hours/piece. Compared with cemented carbide blades, the service life is longer, and the processing efficiency and processing accuracy can meet the highest quality requirements.
