When sourcing metal components, one of the first decisions you’ll face is whether to go with CNC machining or sheet metal fabrication. Both are powerful techniques—but each serves a different purpose.
At Bisonox, we help clients choose the right process based on cost, precision, speed, and material requirements. Here’s a breakdown to help you decide.
What is CNC Machining?
CNC (Computer Numerical Control) machining uses cutting tools to precisely remove material from a solid metal block. It’s ideal for:
- Complex geometries
- Tight tolerances
- High-precision components
- Prototyping or low-volume production
Example: Gear housings, tool parts, enclosures with fine detail
What is Sheet Metal Fabrication?
This process involves cutting, bending, and welding flat sheets of metal into desired shapes. It’s perfect for:
- Lightweight structures
- Brackets, panels, and enclosures
- Faster and more cost-effective production at scale
Example: Electrical panels, mounting plates, control cabinets
CNC vs. Sheet Metal – A Quick Comparison:
| Feature | CNC Machining | Sheet Metal Fabrication |
|---|---|---|
| Material Type | Solid metal blocks (bars, billets) | Flat metal sheets |
| Complexity | High – 3D shapes, precision | Medium – mostly 2D/3D folds |
| Setup Time | Longer (complex programming) | Faster (for simple cuts/bends) |
| Cost (per part) | Higher for small batches | Lower for bulk runs |
