Robotic slot finishing with abrasive cords

On a robotic finishing application, we have to finish some slots to break the sharp edges (and remove very small secondary burrs). Unfortunately the access to theses slots is very limited so we can not finish it with brushes. Manually the operator use some Mitchell another way to finish slots with small clearance in front of the slot (0.25 in).

There are a number of technologies that may work to remove the burrs; however, you did not provide enough info to make a recommendation. What material are you working, how big is the part, what volume?

We offer a service called cryogenic deburring. We freeze the part to protect the surface finish and critical tolerances. At the same time we blast the part with media sized from 0.006" to 0.060" depending on the part. This process is easily able to get inside small slots, recessed holes and other hard to reach places.

It may be a process you want to look into.
