Special Burnish Tools

Taper Burnishing Tools

Taper burnishing tools can be used for internal and external tapers. The tools are made to a precise angle to match the pre-machined dimensions and are supplied with a pressure control assembly in the shank. The tool feeds in to the work piece until the desired load is applied and after a few seconds dwell the desired finish is achieved.

Sizing Tools

Sizing Tools, or parallel expanding tools, are used where intersecting holes or thin wall sections exist. The tools can be used for I.D. or O.D. applications where high demands on straightness and parallelism are required. The tool enters the work piece with the rolls collapsed and once in position the rolls expand radially to achieve the desired size.
