Autobuff

  • Safe Automated Parts Finishing
  • Higher Yields
  • Consistent Quality

A buffing and grinding machine for polishing, grinding, or deburring multiple, rack loaded parts in a single cycle. Whether the application involves finish grinding of castings or forgings, polishing seal seats on drive shafts or edge deburring of textile parts, Mitchell Machine will custom configure and tool the AutoBuff for optimum production.


“We were both impressed and surprised at the fact that such a rough initial surface could be brought to a consistent, high gloss final finish on one machine dry run with a set of convolute wheels with no compound. In the field, the same polished, satin finish would have to be produced by skilled operators using multiple steps of abrasive products including cotton buffs, compounds and set-up wheels.”
