CURING of RESIN BOND GRINDING WHEELS
Curing of Resin Bond Grinding Wheels
A proper and standardized curing process, is the one of the most important step in grinding wheel production.
A curing process consists of curing temperature,holding temperature,holding time,heating rate and other conditions. The actual curing process is complicated, affected by many factors:
1. raw materials:
abrasive nature,grain size,
bond material quantity,volatile matter, condensation rate,liquidity
additives quantity,nature,volatile matter
2. grinding wheel: shape, specification,grade,hardness,density and porosity
3. heating: curing oven type and specification, wheels loading method, heating method
Normally, the exact curing curve is only determined by experiments, an experienced engineer can set a reasonable curing curve by experiments. A proper and standardized processing technology dominates the the performance of grinding wheels,such as higher strength and better grinding effeciency.
