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:

Which One Should You Choose?

Choose CNC machining if:

  • You need highly precise or complex parts
  • The material is thick or non-standard
  • Volume is low or you’re prototyping

Choose Sheet metal fabrication if:

  • Parts are structural or enclosure-based
  • Speed and cost matter
  • Large volume production is expected

At Bisonox, we help clients evaluate their part designs and recommend the most efficient, cost-effective manufacturing process.

Bonus: Hybrid Projects? We Can Do Both.

Some products need a combination—like a sheet metal body with CNC-machined inserts. Our supplier network supports both processes under one roof.

Conclusion

Whether it’s tight-tolerance precision or scalable production, the choice between CNC and sheet metal can impact everything from cost to lead time. Need help choosing the right process? [Send us your drawings →]
