Abstract
PURPOSE: To obtain a resinoid revolving disc grindstone with high porosity and high hardness by hardening heat curing resin to shape the grindstone having a specific gravity 2.2 or less and a degree 0.25 or less.
CONSTITUTION: Using heat curing resin such as phenol, abrasive particles are bonded rigidly to shape a resinoid revolving disc grindstone having a specific gravity 2.2 or less and a degree 0.25 or less. Before burning, abrasive particles and a resin such as phenol resin are mixed to shape a thin revolving disc grindstone approximately 8mm or less thick a little thinner than a specified dimension. Some those products are piled and burnt into one body. The finish of the grindstone can be supplied with high quality.
