Due to the needs of the industry and the need for cutting technology, the current cutting blade technology is more and more developed, and the hardness technology of the cutting piece is also getting higher and higher. The cutting piece is made of high-strength resin and preferred special abrasive, and the allowable line The speed is large, both exceed 50 m / s, it is not easy to be brittle; the cutting is sharp, the cutting heat is very small, and the heat of the cutting piece sample is shallow, so as to minimize the interference. The China cutting disc for metal talks about the importance of the hardness of the cutting piece. Cutting sheets are widely used in machinery, automobiles, ships, metallurgy, chemical industries, etc. They can also be used in the renovation and equipment repair of modern houses and workshops. Professional grinding general metal. Stainless steel. Crushed steel. Tool steel construction metal. Casting Gray iron, hard cast iron metal. Superhard abrasive itself has a very high hardness, so it can process a variety of high hardness materials, especially materials that are difficult to process with ordinary abrasives. For example, diamond abrasives are used to process hard alloys and ceramics. Agate. Optical glass. Semiconductor materials. Stone, concrete and other non-metallic materials and non-ferrous metals. The resin cutting piece belongs to the grinding wheel and is also a kind of grinding tool. The common processes for producing such a resin grinding wheel resin EN12413 cutting discs are as follows: cold pressing process: the bonding agent used has a wetting agent and a powdery resin. Usually used as a wetting agent, such as liquid phenolic resin, furfural, decyl alcohol, cresol, etc., the most used is a liquid phenolic resin. Semi-hot pressing process: the pressing temperature is generally 50-65 ° C. At this pressing temperature, the viscosity of the liquid resin becomes small, and the powdery resin can be well integrated, thereby improving the fluidity of the entire resin system and making it easier. Fully penetrate the space, even if the pressure of the press is not too high, it can be well-formed, and the holding time does not need to be too long, especially suitable for the automatic pressing production line for continuous operation. Hot pressing process: Mixing requirements are different from cold pressing process. Generally, a dry mixing method is used, or 1% of furfural is used as a wetting agent to wet the abrasive, and then mixed with powdered resin.
