Bass said. “The parts we’re generating are inside the trans- mission housing, so if burrs are breaking off, they can be a catastrophic failure for that transmission. You cannot have any burrs in a transmission.”
“When you automate and put it in a production line, you’re pretty much guaranteed it’s going to get deburred, so it’s a more controlled process,” he said. “We looked at the pro- cess; we’ve never made this type of part before. We realized an automated system would ensure a more robust process and the quality of deburring would be better. We never even considered manual for this product.”
Those types of parts, asymmetrical with teeth and castel- lations on them, are harder to deburr by hand, especially in a high-volume production situation. The ability to automate the process reduces fatigue and wear and tear on employees, so it benefits safety along with productivity. “When you’re doing the high volume we have, you have to have a consistent sys- tem that you can rely on,” Bass says.

The automated deburring system used at the Cloyes pro- duction facility was designed and manufactured by Cleveland Deburring Machine Co. (CDMC; Cleveland, OH), so Bass approached that company about designing and creating deburring equipment for the two HHI machining facilities in Bolingbrook, IL, and Fraser, MI, that would be making the transmission parts. CDMC frequently uses Weiler brushes in its equipment and deburring applications. For HHI’s needs in this case, CDMC determined a brush made from ceramic material would provide the lowest cycle time. At HHI, about 10–15% of the products machined in-house require automated deburring. Of those, the majority are using a deburring process with brushes—mostly Weiler brushes, Bass said.
The two lines that use the automated brush deburring process—in place for about two years now—at HHI’s facilities in Bolingbrook and Fraser each produce about 700,000 units annually. That’s full production of three shifts a day, five days a week.
The automated deburring equipment used by HHI has multiple stations and tools that run simultaneously, so three or four brushes hit different parts of the burr at the same time. The parts are put into one end, and they come out the other end complete and deburred. “So every 10 seconds you index a complete part,” Bass said. “The operator never has to intervene. We want the workers to worry about the process as a whole, not to worry specifically about deburring.”
