The right finish for your part
Coordinate dimensional, functional and cosmetic requirements with the machining plan. Each treatment is confirmed for the selected material and drawing.
As machined and deburred
A practical starting point when function takes priority over a uniform cosmetic appearance. Specify edge breaks and acceptable tool marks.
Anodizing
Commonly requested for aluminum parts. State type, color, coating thickness and surfaces requiring masking. Allow for dimensional change at fitted features.
Bead blasting
Creates a more uniform matte appearance on accessible surfaces. Specify cosmetic faces and any areas where blasting is prohibited.
Passivation
Available by agreement for suitable stainless steel components. Specify the required standard, cleaning needs and documentation before quotation.
Plating and coatings
Material compatibility, thickness, adhesion requirements and any hydrogen-embrittlement precautions must be reviewed for the chosen process.
Grinding and polishing
Define the surfaces, roughness value, dimensional tolerance and measurement method. A visual description alone does not define a measurable roughness specification.
Define the finish before machining
Provide a finish specification or agreed reference sample, color, thickness, masking areas, critical fits and inspection criteria.
Surface finishing is coordinated as part of a machined-parts project. Availability, compliance requirements, documentation, cost and lead time are confirmed in the quotation.
Finishing review checklist
- Material grade and condition
- Functional and cosmetic surfaces
- Coating thickness and dimensional allowance
- Masking, threads and electrical contacts
- Roughness and acceptance criteria
- Packaging protection after treatment
