The ID Multi-Roller Burnishing Tool consists of a cage, which retains tapered rolls rotating around on an inversely tapered mandrel. Within the work-piece, the tool is sized so that the roll develops a pressure that exceeds the yield point of the softer work-piece. These tools are adjustable in increments of 0.0001″ and available in a variety of sizes, reaches, and roll lengths to suit a wide range of applications.

ID Multi-Roller Burnishing Tool Operation
Three Roll Designs For Close Approach Applications

Through Rolls
Rolls with greater radius relief are used for through holes (Roll Style 1). These tools are self-feeding and a release clearance is required.
These rolls are interchangeable between blind and through cages.

Blind Rolls
Blind rolls burnish closer to the bottom of a hole or bore than through rolls (Roll Style 4).
These rolls are interchangeable between blind and through cages.
