A flexible or semi-rigid support fixture is sized and shaped to supportably engage a surface of a polymeric matrix object such as an organic bonded abrasive grinding wheel. The support fixture is utilized to support the object to help prevent slumping and/or expansion during thermal curing operations. The fixture is fabricated from a material, such as silicone rubber, that is capable of withstanding heat commonly associated with thermal curing operations and which provides sufficient resilience to permit use with objects manufactured within a relatively wide range of dimensional tolerances. Suitable materials include silicone rubber or other polymers or copolymers such as PTFE, FEP, Polyimide or blends with or without fillers or substrates.

Support fixture for thermal curing processes

Resinoid and vitrified bonded abrasive products containing filament shaped sintered alumina based abrasive made up predominantly of fine alpha alumina crystals.

Bonded abrasive products containing sintered sol gel alumina abrasive

A combination of a cup shaped or cylindrically shaped grinding wheel and a mounting means for such a wheel.

Grinding wheel mounting means

The grinding performance of organic bonded abrasive bodies whose abrasive portion is wholly or partially composed of aluminous abrasive grits is significantly improved by providing a magnesium oxide-rich or manganese oxide-rich coating on furfural-wetted grits just prior to addition of resin and filler in the mixing process.
