Bend Then Drill: Crank Links in One Shop
High-precision 3D CNC bending of stainless crank links followed by drilling at the ends - bend, drill, thread and weld combined in one workshop.
Key Specifications
- Materials
- Stainless steel rod
Key Features
- Bends placed clear of drill points
- End holes drilled after forming
- One shop, two processes, zero freight
- Drawing verification at the station
Why Buy Bend-Drill Parts From Two Suppliers?
Short answer: You should not. This video shows stainless crank links bent on a 3D CNC machine, then moved to drilling so the end holes land exactly where the drawing says - two processes, one shop, one invoice.
What the Video Demonstrates
| Step | Operation | Result |
|---|---|---|
| 1 | 3D bends formed | Crank geometry |
| 2 | End drilled | Mount hole done |
| 3 | Drawing check | Both features proven |
| 4 | Row staging | Batch ready |
Key Applications
- Linkage arms with pivot holes
- Control levers with mount ends
- Frame spreaders and braces
Combined Flow vs Split Suppliers
| Bend shop + drill shop | One shop (shown) |
|---|---|
| Freight between steps | Bench to bench |
| Tolerance stack-up | One datum chain |
FAQ
Can you tap the holes too? Threading runs in-house after drilling.
What about welding on extra parts? TIG and spot welding finish assemblies here.
