Three kinds of processing technologies for cutting discs of resin grinding wheel:

Resin cutting disc belongs to the grinding wheel, is also a grinding tool. The following three technologies are commonly used to produce resin grinding wheel cutting discs:

One, cold pressing process: the use of the binder wetting agent and powder resin, commonly used as wetting agent liquid phenolic resin, furfural, furfuryl alcohol, cresol, etc., with the most is liquid phenolic resin.

Two and a half, and hot-pressing process: pressing temperature is 50-65 ℃, commonly in the pressing temperature liquid resin viscosity decreases, can very good the powdered resin together, increase the liquidity of the resin system, it is easier to penetrate the space fully, even as the pressure of the compressor is not too high, can very good shape, the holding time also do not need too long, especially for continuous operation of automatic production line.

Three, hot pressing process: mixing requirements and cold pressing process, generally adopt the dry mixing method, or use less than 1% of the weight of the abrasive furfural wetting agent wetting abrasive, and powder resin mix evenly.
