Model 2901N Automatic Gear Burnishing
ITW Heartland/SpiroidPosted 07/21/2011
For burnishing internal ring gears for automatic transmissions. Removes or reduces nicks, burrs, and heat-treat scale while improving surface finish. Used instead of honing and finish grinding when process calls only for nick or burr removal. Ideally suited for internal ring gears to remove burrs from the chamfering operation.
Gears are moved through the machine by flat top conveyor and shuttled onto the burnishing area. Gears are captured between three burnishing tools and rolled. There is no oscillation or coolant used with this operation.
Process improvement, long tool life (500,000 - 750,000 cycles).
