How Are Both Ends of an Aluminum Ring Handle Tapped in One Cycle?
Short answer: With a twin vertical-spindle tapping machine. This video shows bent aluminum ring handles being pushed into the fixture so both round end bosses sit under the taps - one cycle cuts both mounting threads, and the finished pulls stack up on the table ready for assembly.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Place | Push-in fixture on the table | Both end bosses aligned under taps |
| Tap | Twin vertical belt-driven spindles | Two mounting threads cut at once |
| Inspect | Finished ends shown in hand | Clean, full-depth aluminum threads |
| Stack | Row of ring pulls on the table | Fast cycle, high hourly output |
Key Applications
- Aluminum ring pull handles with screwed end covers
- Handle production lines pairing bending and tapping
- High-volume cabinet and furniture hardware
- Any two-end thread pattern on bent parts
Twin-Spindle One-Cycle vs. Single-Tap Tapping
| Criterion | Single tap | Twin-spindle machine |
|---|---|---|
| Holes per cycle | One | Two at once |
| Re-positioning | Every hole | None |
| Fixturing | Clamp each time | Instant push-in |
| Output per operator | Lower | Doubled or better |
FAQ
What parts does this machine tap? Bent aluminum ring handles with round end bosses as shown; tap spacing and the fixture are matched to your handle geometry.
Are the threads full depth for assembly screws? Yes - the video shows clean, full-depth machine-screw threads in both ends of every part inspected.
Can it be added after an existing bending machine? Yes - it is the natural second station: bend the ring handles first, then tap both ends here in one cycle.
