Fabrication Tolerances for Dimensional Variance in Sheet Metal and Machined Parts
Finish Tolerances
When it comes to surface finishes, it's important to factor them into your overall design, as our surface finishes can add anywhere from 0.0004" to 0.003", depending on the finish. For example, when mounting a component that requires a 1" diameter hole (on a surface that will be powdercoated), be sure to call out a 1.006" hole diameter. This will allow for 0.003" of powdercoat per side.
Surface Finish | Tolerance |
---|---|
Masking Placement | ± 0.080" | 2.03mm |
Anodizing Type 2 | + 0.0004" | 0.01mm |
Anodizing Type 3 | + 0.001" | 0.03mm |
Powdercoating thickness | + 0.003" | 0.08mm |
