How Are Internal Threads Tapped Into Bent Aluminum Handle Ends?

Short answer: On a multi-spindle tapping machine. This video shows bent aluminum tube handles being loaded by hand while several tapping spindles cut internal threads into the open ends at once, each flood-cooled by a flexible nozzle, so both ends of every handle are threaded cleanly in a single cycle.

Key Applications

  • Threaded aluminum pull and grab handles
  • Tube-end fastening where screws thread into the part
  • Batch hardware production on a benchtop multi-spindle
  • Replacing single-spindle tapping that threads one end at a time

FAQ

What is being machined in the video? Bent aluminum tube handle parts, with internal threads tapped into their open ends.

How are the threads kept clean in aluminum? Each tapping spindle runs under a flexible coolant nozzle that floods the cut, clearing chips and producing full, clean internal threads.

Can the machine handle other handle sizes and thread specs? Yes - spindle tooling, taps and end supports are matched to your tube diameter and thread specification on request.
