Finishing is part of the part specification
CNC surface finishing services cover the requested condition of a machined part after cutting. The right finish depends on the material, drawing, function and appearance requirements. A finish name alone may leave important details open, so define the required outcome and how it will be checked.
Describe boundaries and critical dimensions
Identify the substrate and finish reference, including color or appearance where relevant. Mark areas to mask, surfaces that must remain unfinished, and dimensions that need to be evaluated before or after treatment. Call out threads, fits, sealing faces and mating features that could be affected by the finishing step.
Make acceptance clear
State whether acceptance is visual, dimension-based or supported by a specified report. List the drawing revision, quantity, packaging and any approved substitutions. If the finish is still under review, record it as an open item rather than assuming a standard.
For a finish-specific request, see anodizing services for machined parts or wet painting services. For broader part-making scope, see CNC machining services.
RFQ details to include
- Material grade, quantity and drawing revision
- Finish name or governing customer specification
- Color, masked areas and surfaces to protect
- Critical dimensions and post-finish inspection
- Packaging and any quote exclusions
Confirm feasibility and acceptance for the specific material and geometry before releasing the order.
