The difference between grinding wheel and cutting disc:
Many people think that grinding wheel and cutting disc are the same product and have the same function. In fact, this is not the case. There is an essential difference between the two.
Grinding wheel can be cut, polished, and polished in different shapes; cutting disc is only used for cutting, and cutting disc is divided into resin cutting disc, diamond cutting disc, etc.
Grinding wheel is the main type of abrasive in grinding. Grinding wheel is a porous body made by adding binder to abrasive, pressing, drying and roasting. Due to different abrasives, binders and manufacturing processes, the characteristics of grinding wheel vary greatly, which has an important impact on the processing quality, productivity and economy of grinding. The characteristics of grinding wheel are mainly determined by factors such as abrasive, particle size, binder, hardness, organization, shape and size.
Cutting disc belongs to grinding wheel, which is made of abrasive and binder resin for cutting ordinary steel, stainless steel metal and non-metallic materials. It is divided into resin cutting disc and diamond cutting disc.
As a professional grinding wheel manufacturer, Shenzhen Longzhouli Tools will share with you the specifications, models, prices, pictures, etc. of various grinding wheels in detail. The products are of high quality and guaranteed quality. With professional technical strength, advanced production equipment or testing equipment, various grinding wheels with special purposes can be developed according to different requirements of users.
Next, Longzhouli Grinding Wheel Manufacturer will share with you the main processing technology of grinding wheel cutting discs:
1. Cold pressing process: The binders used in grinding wheel cutting discs are wetting agents and powdered resins. Generally, liquid phenolic resins, furfural, furfuryl alcohol, cresol, etc. are used as wetting agents. Liquid phenolic resins are used more.
2. Semi-hot pressing process: The limiting temperature of grinding wheel cutting discs is generally 50-65℃. At this limiting temperature, the viscosity of liquid resin decreases, which can well integrate powdered resin, improve the fluidity of the entire resin system, and make it easier to fully penetrate various spaces. Even if the pressure of the press is not too high, it can be well formed, and the pressure holding time does not need to be too long. Grinding wheel cutting discs are generally suitable for automatic production lines with continuous operation.
3. Hot pressing process: The mixing requirements of grinding wheel cutting discs are different from those of cold pressing process. Generally, dry mixing method is used, or furfural less than 1% of the abrasive weight is used as a wetting agent to wet the abrasive, and then mixed evenly with powdered resin.
