The main processing technology of cutting wheel

1. Cold pressing process: The binder used in the cutting wheel includes moisturizing agent and powdered resin. Generally used as moisturizing agent are liquid phenolic resin, furfural, furfuryl alcohol, cresol, etc. Liquid phenolic resin is mostly used.

2. Semi-hot pressing process: The limiting temperature of the cutting wheel is generally 50-65°C. At this limit temperature, the viscosity of the liquid resin becomes smaller, and the powdery resin can be well integrated into one body, so that the fluidity of the entire resin system Progress, more simple and full penetration of various spaces, even if the pressure of the press is not too high, it can be formed well, and the pressure holding time does not need to be too long. The cutting wheel is generally suitable for the automatic production line of consecutive operations.

3. Hot pressing process: The mixing requirements of the cutting wheel are different from the cold pressing process. The dry mixing method is generally used. Perhaps less than 1% of the abrasive component of furfural is used as a moistening agent to wet the abrasive, and then mixed with the powdered resin evenly.
