CNC Machining

How quickly can Protocase build CNC machined parts?

Lead times vary depending on part complexity and customization requirements, but Protocase specializes in rapid manufacturing with lead times as fast as 2-3 days for custom CNC machined parts.

Can I order a single CNC machined part?

Yes. Protocase specializes in custom prototypes and low volume production, including one-off CNC machined parts.

What tolerances can Protocase achieve with CNC machining?

Standard Precision: X ≥ ±0.005”(0.13mm)

Premium Precision: ±0.005”(0.13mm) > X > ±0.001”(0.025mm)

Ultra Precision: ±0.001”(0.025mm) ≥ X ≥ ±0.0001”(0.0025mm)

X=Tolerance

Nominal Dimension ± X

What kind of a finish does CNC machining leave?

Due to the spinning motion produced by the CNC milling machine's cutter, the surface finish of CNC machined parts will have visible toolmarks. If you require a smooth, unblemished finish to your part, we recommend choosing a secondary finish: grained finish (can only be applied to the outside of machined enclosures due to geometry) or powder coat.

What's the advantage of using a larger corner radii?

Using the largest possible radii for your design will improve surface finish quality and lower machining costs.

Large Radii = Larger Tools = Faster Cuts = Less Time = Lower Cost
