Aluminum caster in NY finds flexibility in deburring solution.

Position:The finish line

For Tom Wittmeyer, flexibility translates into production Success.

"Flashing on die cast parts must be removed for operational, safety, and aesthetic reasons, but how this chore is completed has always come under considerable scrutiny by manufacturing engineers and, more important, Occupational Safety and Health Administration (OSHA) regulators," says Wittmeyer, process technician for TPi ARCADE Inc., Arcade, NY. "With the new, patented Flexdeburr RC-660, we have cleared the hurdle, cutting the deburring time in half and minimizing employee involvement. The automated tool allows us to robotically remove the flashing quickly and efficiently while virtually eliminating the operator's manual deburring and exposure to casting dust."

The Flexdeburr RC-660, provided by ATI Industrial Automation, Apex, NC, gets high marks from Wittmeyer. "We have always looked for ways to implement robots to perform these routine and repetitive deburring tasks," he says. "However, we were somewhat restricted when programming the robot. Typically, robotic programming moves the deburring tool along a path defined by discrete points, and that path may not exactly coincide with the shape or contour of the surface to be deburred due to variations in the part itself or to differences between the part edge and the exact path the robot has interpolated.

"Implementing the Flexdeburr has solved that problem. The patented flexible deburring tool with inherent compliance utilizes a unique 'pivoting' motor and spindle arrangement that provides radial compliance that accommodates differences between the part edge and the actual tool path. The tool is designed to follow the part profile accommodating surface variations."

Reducing operations

Harmony Castings LLC/TPiARCADE Inc. provides a multitude of casting services specializing in aluminum V-process manufacturing. Its manufacturing experts operate a wide variety of state-of-the-art, computer-controlled equipment to produce castings with finer finishes and tighter, more consistent tolerances. The V-process provides quick turnaround, high-quality castings ideally suited for prototyping and low-volume applications.


Some of the advantages of the V-process are zero-degree draft, which reduces weight and minimizes postcast machining; thin-wall thicknesses of 0.125" over large areas and 0.09" in small areas; tight tolerances as much as twice as accurate as sand casting; unlimited pattern life lasting as long as...
