System deburrs high-volume fineblanked parts

Abtex Corp. has designed and built the largest Tri-Ten deburring system in its history, intended for deburring high-volume fineblanked parts. It operates three shifts/day, seven days/week, with an annual throughput of more than 15 million parts.

The machine can be bulk-fed by operator or robot, or fed directly by the upstream press. The infeed conveyor passes parts under a vision system before they enter the deburring stations. The vision system is programmed to stop the machine if parts are overlapped, stacked, or otherwise improperly loaded. The system also communicates with the upstream press, centralized coolant system, and downstream conveyors.

Three planetary heads remove burrs from parts with thicknesses of 0.12 to 0.02 in. Three custom-designed, 10-in. flap discs on the first head remove the primary stamping burr. Six 10-in., application-specific abrasive filament brushes on the second and third heads eliminate secondary burrs and provide the specified edge radius.

After deburring, a gap conveyor transfers parts to a heavy-rinse station and demagnetization and blowoff bays that remove residual debris or particulate.
