Universal(TM) Burnishing Tool Offers Versatility to Burnish Multiple O.D. Surfaces

Achieves finish better than required, with faster production

JOB SHOP WAS SEEKING A BETTER FINISHING SOLUTION for their cylinder sleeves. They were using a finishing insert fed at the slow rate of .002 IPR (0.05mm/rev), followed by a polishing process, in order to achieve a finish requirement of 16 microinch (0.4 micrometer) Ra or better.

Cogsdill recommended burnishing as a faster and more effective way to obtain the
required finish. The customer had a number of different piece parts within a family of
parts; the use of standard O.D. burnishing tools would be costly. They wanted to burnish all of them with one tool. Cogsdill had the solution: the UBT-T Universal(TM) burnishing tool. This versatile tool can burnish shafts, faces, tapers, contours, and large I.D.s. It is offered in right-hand and left-hand models, with adjustable roll orientation.

The customer achieved finishes better than required, while reducing their production time and associated costs.
