How to make marble work more efficiently?
1. 7 inch diamond cutting saw blades were sintered in vacuum protective atmosphere by cold pressing and hot sintering process. The tool head sintered after cold pressing is very sharp in the sawing process, and the production efficiency is improved a lot. However, the vacuum protective atmosphere sintering can prevent powder oxidation and activate sintering, which not only improves the performance of the tool head, but also extends the life of the graphite mold, and also reduces the production cost.
2.In the process of diamond saw blade processing, if the cutter head matrix has a good holding force on the diamond, the diamond will have a good edge and will not fall off prematurely. When cutting, it is sharp and efficient.
In addition, a small amount of molybdenum, chromium and tungsten powder can be added to the matrix powder. Due to the good wettability and affinity of this kind of powder to diamond, carbide alloy is formed on the surface of diamond and matrix metal during sintering, which is conducive to the chemical bonding and metallurgical combination of diamond and matrix metal, thus greatly improving the holding force of matrix to diamond.
3. Use ultrafine powder and pre alloy powder. Superfine powder can reduce sintering temperature and improve the hardness of matrix. The pre alloyed powder can shorten the contact time between powder and air, prevent the premature loss and segregation of low melting point metal, improve the strength of sintered products and increase the holding power of diamond.
4. Some rare earth elements (such as rare earth lanthanum, cerium, etc.) were added to the matrix powder. It can obviously reduce the performance of bond wear marble cutting blade and improve the cutting efficiency of diamond saw blade.
5. Improve the production technology and equipment quality of saw blade; the quality of saw blade is closely related to the production technology and equipment of saw blade. High quality production technology or equipment can improve the quality and performance of marble saw blade; many manufacturers are trying to make breakthroughs in research.
Due to the high hardness and modulus of elasticity of diamond, it is difficult to produce plastic deformation when sintering at high temperature. It is beneficial to improve the wear ratio of cutting tools by selecting the ratio and increasing the density of diamond particles before sintering.
6. High strength diamond with stable production performance, coarse particles and good thermal stability is adopted.Fish hook Segment marble Diamond saw blade is basically fixed on the working matrix by the diamond and matrix under certain technological conditions, mainly relying on the grinding agent and cutting effect of diamond to process different stones. Therefore, the quality, granularity and concentration of diamond play a decisive role in diamond tools.
7. The correct welding process, the diamond saw blades are all welded by high-frequency welding machine, so it is very easy to have the second "burn" of the cutting head and the phenomenon of cutting head falling when welding the saw blade. It is not only unsafe, but also affects the production. Therefore, high strength and good permeability silver solder chips should be used for welding.
8. Improve the particle size ratio of diamond. In the traditional ratio, the cutting head should be sharper, and more coarse-grained diamond should be used, otherwise fine-grained diamond should be used. But it can't achieve the best efficiency.
