The ultra-thin grinding wheel belongs to the grinding wheel and is also a grinding tool. Ultra-thin cutting disc manufacturers will give you a specific introduction.
There are three main processes for resin grinding wheel cutting discs:
1. Ultra-thin cutting disc manufacturers will use the cold pressing process. The binders used are wetting agents and powdered resins. Liquid phenolic resins, furfural, furfuryl alcohol, cresol and the like are commonly used as wetting agents. The most used is liquid phenolic resin.
Second, the ultra-thin cutting disc manufacturers will use the semi-hot pressing process. The pressing temperature is generally 50-65°C. At this pressing temperature, the viscosity of the liquid resin becomes smaller, and the powdery resin can be well integrated. The fluidity of the entire resin system is improved, and it is easier to fully penetrate each space. Even if the pressure of the press is not too high, it can form well. The pressure holding time does not need to be too long, and it is generally suitable for continuous automatic pressing production lines.
Third, the ultra-thin cutting disc manufacturers will use the hot pressing process. The mixing requirements are different from the cold pressing process. Dry mixing is generally used. Or use furfural less than 1% of the weight of the abrasive as a wetting agent to wet the abrasive, and then mix it evenly with the powdered resin.
