Abstract:
An apparatus for finishing surfaces of solid materials, comprising:a frame having a front end and a back end;a conveyor system extending generally from said front end to said back end;a drive means supported by said frame, said drive means connected to a drive shaft to provide a first axis of rotation;at least two orbital shafts coupled to said drive shaft whereby each orbital shaft provides a second axis of rotation;at least two discs, each of said at least two discs having a center providing a third axis of rotation, each of said at least two discs having a material engaging surface;each of said at least two orbital shafts being coupled to each of said at least two discs in an offset position form said center such that each of said at least two discs is rotatable about said third axis while said third axis rotates about said second axis;a cam and counterweight assembly to provide the coupling between the orbital shafts and the discs; andwherein said material engaging surface is capable of being detachably covered by a finishing abrasive whereby when each of said at least two discs is rotating and each of said at least two discs contacts a surface of said solid materials, said finishing abrasive finishes the surface of said solid materials.
