A compact, wet Tri-Ten planetary head deburring system is available from Abtex Corp. in a return-to-operator configuration. The system deburrs both sides of flat parts up to 4.5" in diameter in a single pass using three Abtex fiber abrasive brushes. The workpiece is drenched in coolant as it is deburred to keep parts clean and extend brush life. After both sides of a part are deburred, it passes under a final coolant rinse, followed by an air knife to remove excess coolant, and is demagnetized before exiting at an opening next to the entrance.
