HIGH POROSITY SUPERABRASIVE RESIN PRODUCT, AND METHOD OF MANUFACTURE

PROBLEM TO BE SOLVED: To provide a grinding tool that has sufficient strength and wear characteristics and is capable of roughly grinding or finishing hard workpieces.SOLUTION: A superabrasive product, such as a superabrasive tool, includes a superabrasive grain component and a porous continuous phase that includes a thermoplastic polymer component in which the superabrasive grain component is distributed. A superabrasive product precursor to the superabrasive product includes a superabrasive grain component, a bond component and a polymer blowing agent of encapsulated gas. A method of forming the superabrasive product includes a step of combining a superabrasive, the bond component and the polymer blowing agent of encapsulated gas to form the superabrasive product precursor. The combined superabrasive, bond component and polymer blowing agent of encapsulated gas are heated to a temperature and for a period of time that causes release of at least a part of the gas from encapsulation within the blowing agent.
