This not only improves the processing efficiency, but also improves the processing quality. Such as SG cutting tablets. It is a novel ceramic alumina low price disc for metal. It uses pure corundum as raw material and combines it with water and other medium such as magnesium oxide to produce a blocky gel. After drying, it forms a brittle object. Mill it to the desired particle size, from 1300 ° C to 1400 ° C to temperature
Sintered. Its hardness is much higher than ordinary alumina, and its toughness is good, so it can be operated under higher speed and large load conditions, and the metal removal rate is more than three times higher than ordinary alumina. Its biggest advantage is that the grinding zone has a low temperature, and the cutting piece always has a sharp grinding edge, and the shape of the aluminum abrasive cutting disc is good and the time is long. Cubic boron nitride grinding. It is a hard and wear-resistant cutting piece with excellent properties such as high thermal conductivity and chemical resistance. The latest generation of cutting discs are characterized by sharp, high strength and can be used for unsupported cutting. These features reduce the grinding forces during grinding and reduce damage to the workpiece.
In fact, the strict control of the synthesis conditions of the dicing sheet will directly affect the final crystal form of the abrasive particles and the physical properties including the strength, thermal stability and fracture characteristics, thereby affecting its performance. For example, the four ABN products produced by De Beers have their own different characteristics. ABN200 is a brittle black cutting piece used primarily for ceramic bonded grinding tools and metal coated resin bonded grinding tools. ABN300 has similar strength to ABN200, but is amber in color and is commonly used in metal and epoxy bonded grinding tools. ABN600 is black and is a typical high-strength cubic boron oxide cutting sheet with a specific crystal face. It is also used for the bonding of metal and epoxy resin. ABN800 is the latest generation of high-strength single crystal cubic boron oxide material. ABN800 has similar strength to ABN600, but it can be seen that there is a significant difference between the two, the former has sharp edges and high thermal stability.
During the grinding process, the block or round abrasive particles can be considered to be ground with a large negative rake angle to the workpiece. For sharp polygonal particles, in most cases, a large positive rake angle is used for grinding. Therefore, when grinding a steel having a high carbide content (such as some high speed steel), it is preferable to select a fiber cutting disc Chinese supplier particle having a negative rake angle. Sharp, polygonal horns with a large positive rake angle have potential advantages when machining tougher tough materials such as certain high speed steels and case hardened steels.
