Microfinishing and roller burnishing machine

A combination surface finishing machine for microfinishing and burnishing a workpiece comprising:

• a base;
• a driver means for rotating said workpiece about a central axis, said driver means supported on said base;
• at least one microfinishing assembly affixed to said base, said microfinishing assembly adapted to be positioned adjacent said workpiece and having at least one finishing means for surface finishing said workpiece, said at least one finishing means lying in a plane generally perpendicular to said central axis of rotation of said workpiece;
• and
• at least one burnishing assembly affixed to said base, said burnishing assembly for applying a burnishing pressure to said workpiece, said burnishing assembly positioned adjacent said workpiece and spaced apart from said microfinishing assembly, said burnishing assembly having a pair of burnishing rollers lying in said plane generally perpendicular to said central axis of rotation of said workpiece wherein said microfinishing assembly and burnishing assembly are operable upon rotation of said workpiece to microfinish and burnish said workpiece respectively such that when said burnishing assembly is applying pressure to said workpiece, a total force applied to the workpiece from said burnishing assembly is divided equally between said pair of burnishing rollers.
