Burnishing

Parts are sized, finished and work hardened by highly polished, precision rollers in one quick pass.

The result is a shiny, reflective finish with superior strength and load-bearing qualities. Burnishing can effectively eliminate minor visual defects, polishing the surface to smoothness of 1μm or less.

At T S Henderson we only use the best specialty manufacturers of burnishing tools to meet our customer requirements.

Surface hardening of the workpiece is achieved simultaneously with sizing and finishing. With certain materials, increases in surface hardness of up to 3 points on the Rockwell “C” scale are attainable.

The smooth, dense, hardened surface produced by the roller burnishing process extends wear life, improves resistance to corrosion and reduces fatigue failures. Friction is also reduced, resulting in noise reduction where shafts are running in bushings.
