The present invention incorporates at least one thermoplastic or elastomeric polymer in abrasive flow machining media either as the sole or as one of the polymeric constituents. The presence of thermoplastic polymer imparts a greater elastomer characteristic (elasticity, compression resistance, increased relaxation times) as contrasted with traditional media. Enhanced elastomeric characteristics enable more uniform abrasive machining. In a particularly preferred embodiment, silicone- or polyorganosiloxane-based medium contains elastic silicone rubber particles dispersed therethrough to achieve increased relaxation times comparable to those attainable with the inclusion of a thermoplastic polymer.
An abrasive machining medium comprising:
A machining medium comprising a viscoelastic base medium selected from the group consisting of a silicone polymer and a polyorganosiloxane polymer, a quantity of abrasive particles admixed therewith, and a quantity of elastic silicone rubber particles admixed with said viscoelastic base medium and said abrasive particles.
