CNC Parts Surface Finishing Services
JADE-CNC provides CNC parts surface finishing support for machined metal and plastic components that require corrosion resistance, résistance à l'usure, couleur, texture, cosmetic appearance, conductivity control, or inspection-ready surfaces.
Surface Finishing Options We Offer
Most CNC machined parts need a suitable finish before assembly, testing, shipment, or end use. JADE-CNC reviews surface finishing requirements such as anodizing, hard coat anodizing, electroplating, passivation, polissage, microbillage, peinture, revêtement en poudre, oxyde noir, traitement thermique, and laser marking according to the drawing, matériel, surfaces visibles, zones de masquage, impact sur la tolérance, et les besoins en matière d'inspection.

Surface Finish Selection Reference for CNC Parts
Surface finishing affects the appearance, résistance à la corrosion, performance à l'usure, conductivité, and assembly fit of CNC machined parts. JADE-CNC peut revoir le dessin, matériel, tolérance, cosmetic requirement, and application environment before recommending a suitable finish.
| Finition de surface | Suitable Materials | Typical Thickness / Effect | Common Purpose | Design / Remarques sur la demande de prix |
|---|---|---|---|---|
| Type II Anodizing | Aluminium | 5-25 microns | Corrosion protection, couleur, cosmetic appearance | Confirm color, scellage, and masking for threaded or precision-fit areas. |
| Type III Hard Anodizing | Aluminium | 25-60 microns | Wear resistance, harder surface, functional protection | Allow for dimensional growth and confirm critical tolerance areas before production. |
| Placage autocatalytique au nickel | Acier, aluminium, alliages de cuivre | 5-50 microns | Uniform coating, résistance à la corrosion, résistance à l'usure | Useful for complex geometry; confirm coating thickness and post-treatment requirements. |
| Passivation | Acier inoxydable | No meaningful buildup | Improves stainless corrosion resistance | Suitable when dimensional change must be minimized. Confirm stainless grade and standard requirement. |
| Microbillage | Aluminium, acier inoxydable, acier, laiton | Surface texture change | Uniform matte appearance, visual consistency | Cosmetic expectations should be confirmed with sample photos or finish references. |
| Revêtement en poudre | Aluminium, acier | 60-120 microns | Outdoor durability, couleur, protective coating | Mask threads, trous, grounding surfaces, and precision assembly features. |
| Oxyde noir | Acier | Very thin conversion layer | Low reflection, dark appearance, light corrosion protection | Often requires oil or sealing for better protection. Not a heavy corrosion-resistant finish by itself. |
| Marquage laser | Most metals and some plastics | Local surface marking | Part identification, logos, traceability marks | Confirm marking position, taille, contrast, and whether the mark is cosmetic or functional. |

JADE-CNC will review whether the requested finish is suitable for the part material, géométrie, tolérance, et candidature.
Surface Finishing FAQ for CNC Machined Parts
JADE-CNC peut revoir l'anodisation, hard coat anodizing, placage, passivation, polissage, brossage, microbillage, peinture, revêtement en poudre, oxyde noir, traitement thermique, marquage laser, and other finish requirements based on drawing and material.
The finish should be selected according to material, fonction, apparence, exposition à la corrosion, wear requirement, conductivité, zones de masquage, impact sur la tolérance, et les besoins en matière d'inspection.
Oui. Anodizing can add coating thickness and may affect precision-fit areas, fils de discussion, trous, et surfaces de contact. Critical areas should be marked before finishing.
Hard coat anodizing is usually considered when aluminum parts need better wear resistance, harder surfaces, or functional protection. Thickness and tolerance impact should be reviewed before production.
Oui. Passivation is commonly used for stainless steel parts to improve corrosion resistance without meaningful dimensional buildup.
Oui. Masking areas such as threads, trous, electrical contact surfaces, faces d'étanchéité, and tight-tolerance features should be reviewed before finishing.
Color can vary depending on material grade, état de surface, lot, processus de revêtement, and supplier conditions. Color expectations should be confirmed with references or samples when appearance is important.
Common checks include visual appearance, épaisseur du revêtement, rugosité, masking condition, dimensions critiques, ajustement du filetage, et surfaces fonctionnelles.
Certaines pièces en plastique peuvent être polies, microbillé, peint, marked, or treated depending on the material and application. The finish method should be reviewed case by case.
Please provide drawings, qualité du matériau, quantité, required finish, color or texture reference, zones de masquage, dimensions critiques, appearance requirements, and inspection documents if needed.
