Application scope of diamond saw blade
(1) Processing of difficult to process nonferrous metal materials
When processing copper, zinc, aluminum and other non-ferrous metals and their alloys, the material is easy to adhere to the tool, and the processing is difficult. Taking advantage of the characteristics of low friction coefficient and low affinity with non-ferrous metals, diamond tools can effectively prevent metal from bonding with tools. In addition, due to the large elastic modulus of diamond, the deformation of the edge during cutting is small, and the extrusion deformation of the non-ferrous metal to be cut is small, so that the cutting process can be completed under small deformation, and the quality of the machined surface can be improved.
(2) Processing of difficult to process nonmetallic materials
When processing hard to process non-metallic materials containing a large number of high hardness particles, such as glass fiber reinforced plastics, silicon filled materials and hard carbon fiber / epoxy resin composite materials, the hard points of the materials cause serious wear of the tools, and it is difficult to process with hard alloy tools, while the diamond tools have 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 towards high accuracy, which puts forward high requirements for tool performance. Due to the low friction coefficient, low thermal expansion coefficient and high thermal conductivity of diamond, it can cut extremely thin chips, which are easy to flow out, have low affinity with other substances, are not easy to generate chip accumulation, have small heat generation and high thermal conductivity, and can avoid the impact of heat on the cutting edge and workpiece. Therefore, the cutting edge is not easy to passivate, and the cutting deformation is small, and can obtain a high-quality surface.
(4) Particleboard woodworking
For large-scale woodworking cutting operations, especially for high density, high hardness and difficult to process plates such as particleboard, density board and anti doubling board, the cutting performance of traditional hard alloy saw blades is difficult to meet. PCD composite diamond saw blade has become a cutting tool for hard materials and an outstanding tool for woodworking dry cutting. Its superhard performance and durable wear resistance are the enemy of woodworking materials. Diamond saw blade has a Vickers hardness of 10000hv, strong acid resistance, and the edge is not easy to passivate. The processing wood has good one-time forming quality and high wear resistance. Compared with hard alloy, it is more wear-resistant The continuous operation time of cutting such as veneer can reach 300-400 hours, and the higher service life can reach 4000 hours / piece. Compared with the carbide blade, the service life is longer, and the processing efficiency and accuracy meet the requirements of higher quality.
