Twin-Spindle Anodized Handle Tapping Machine
A twin-spindle tapping machine threads the mounting holes of flat aluminum profile handles - gold anodized and bare silver, both ends tapped at once.
Key Specifications
- Materials
- Flat anodized and bare aluminum profile handles
Key Features
- Taps mounting holes into flat aluminum profile handles
- Twin vertical spindles finish both ends per cycle
- Handles anodized gold and bare silver alike
- Hollow profile ends hold clean internal threads
How Are Flat Aluminum Profile Handles Tapped on Two Spindles?
Short answer: The taps come down on both ends of the profile. This video shows flat aluminum handle profiles - gold anodized and bare silver - placed on a twin-spindle tapping machine, where vertical taps cut the mounting holes into the ends so the finished pulls stack up on the table.
What the Video Demonstrates
| Stage | Equipment | Result |
|---|---|---|
| Place | Flat handle set on fixture stops | Ends aligned under the taps |
| Cycle | Twin vertical tapping spindles | Mounting holes cut in the profile |
| Compare | Gold and silver parts on table | Same thread, two finishes |
| Inspect | Long handle held to camera | Clean tapped end holes shown |
Key Applications
- Flat-profile cabinet and furniture pull handles
- Anodized and mill-finish aluminum hardware lines
- Finishing station after profile bending
- Batch tapping with one operator at the machine
Twin-Spindle Tapping vs. Manual Single Tapping
| Criterion | Manual single tap | Twin-spindle machine |
|---|---|---|
| Holes per cycle | One | Both ends at the station |
| Thread consistency | Operator feel | Machine-controlled depth |
| Placement | Align and hold | Drop onto stops |
| Finish handling | Rework risk | Anodized parts tapped clean |
FAQ
What parts are tapped in the video? Flat aluminum handle profiles - both gold anodized and bare silver - the same sections formed on the company's benders.
Does the machine tap both ends of the handle? Yes - two vertical spindles thread the mounting ends of one part at the same station in a single setup.
Will tapping damage the anodized finish? The taps cut internal threads inside the profile ends; with parts located on the fixture stops, the visible anodized surface stays clean.
