Stone enterprises urgently need high-quality, high-quality, cost-effective diamond saw blades.
Aiming at the status quo, after many practices, a set of technical solutions for producing high-efficiency, high-quality diamond saw blades has come out.
1. High-strength diamond with stable production performance, coarse particles and good thermal stability (directly close to tfi). The diamond tool is basically fixed on the working substrate by diamond and the carcass under certain process conditions, mainly relying on diamond grinding agent and cutting action to process different stone materials. Therefore, the quality, particle size and concentration of raw materials (diamonds) play a decisive role in diamond tools.
2, although the strong carbon powder elements, improve the diamond holding power. In the processing of the diamond saw blade, if the cutter carcass has a good holding force on the diamond, the diamond will have a good edge and will not fall off prematurely, and the cutting is sharp and the efficiency is high. Generally, a diamond layer is plated with a strong carbon compound to form a metal element such as plating, titanium, chromium, nickel, tungsten, etc., to improve the bonding of the diamond to the carcass powder, and to prevent the diamond from being sintered at a high temperature. Oxidation and graphitization; in addition, a small amount of strong carbon powder elements such as molybdenum, chromium, tungsten powder, etc. may be added to the carcass powder. Because of the good wettability and affinity of the powder for gold and diamond, the formation of a carbon alloy on the surface of the diamond and the carcass metal during sintering facilitates the chemical bonding and metallurgical bonding of the diamond and the carcass metal, thereby greatly improving the tire growth. Body holding power of diamond.
3. Improve the particle size ratio of diamond. In the traditional ratio, the cutter head should be sharper, and more coarse diamonds should be used. Otherwise, fine diamonds should be used. It is true, but it does not always achieve the best work efficiency. Due to the high hardness and elastic modulus of diamond, plastic deformation is difficult to occur at high temperature sintering. Selecting the ratio and increasing the bulk density of the diamond particles before sintering are advantageous for improving the wear ratio of the tool. After several experiments, the general three-grain diamond composition of coarse, medium-thick and fine-grained heads was obtained, and the optimum particle size ratio was 1:0.0227:0.071.
4. Use ultrafine powder and prealloyed powder. Ultrafine powder helps to lower the sintering temperature and increase the hardness of the carcass. The pre-alloyed powder, through the three-dimensional three-dimensional mixing, greatly shortens the contact time of the powder with the air, prevents premature loss and segregation of the low melting point metal, and is beneficial to increase the strength of the sintered product and increase the holding power of the diamond.
5. Add appropriate amount of rare earth elements (such as rare earth lanthanum, cerium, etc.) to the carcass powder. It can significantly reduce the wear performance of the bonding agent and improve the cutting efficiency of the diamond saw blade.
6. The cold-pressing-hot sintering process is used to perform vacuum protection atmosphere sintering. The cutter head which is sintered after cold pressing is very sharp in the sawing process, and the production efficiency is improved a lot, and the vacuum protection atmosphere sintering can prevent the powder from being oxidized and activated and sintered, thereby improving the performance of the cutter head and prolonging the graphite mold. Life expectancy and lower production costs.
7, the correct welding process, the current diamond garden saw blade is welded with high-frequency welding machine, the second "burn" and the phenomenon of the cutter head are easy to occur when welding. Not only is it unsafe, but it also affects production. Therefore, high-strength, high-permeability silver soldering sheets should be used for welding processing.
Based on the above points, a high-quality and efficient diamond saw blade was successfully developed. However, in the production and use of diamond tools, there are many factors affecting the tool. It is also necessary to adjust the stone material according to different stone materials and different sawing machines. Reasonably select and use the saw blade correctly, so that the performance of the saw blade can be improved. Give full play to get good results.
2. The glass slide is at the bottom, which is the carrier for the material you want to observe, that is, you want to put something on it.
3. The cover glass is smaller than the slide glass. The glass slide is mainly used to hold the observation objects. The cover glass is covered on the slide glass and used for fixing.
4. The glass slide is a thicker piece of glass in the transfer slide, which is used to carry the real object. The cover fragment is the small round or square thin one.
5. Mounting is a general term for a set of things, including slides, coverslips and loaded objects
