CNC Parts Surface Finishing Services
JADE-CNC provides CNC parts surface finishing support for machined metal and plastic components that require corrosion resistance, resistenza all'usura, colore, struttura, 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, passivazione, lucidatura, sabbiatura, pittura, verniciatura a polvere, ossido nero, trattamento termico, and laser marking according to the drawing, materiale, visible surfaces, masking areas, tolerance impact, e le esigenze di ispezione.

Surface Finish Selection Reference for CNC Parts
Surface finishing affects the appearance, resistenza alla corrosione, prestazioni di usura, conductivity, and assembly fit of CNC machined parts. JADE-CNC can review the drawing, materiale, tolleranza, cosmetic requirement, and application environment before recommending a suitable finish.
| Finitura superficiale | Suitable Materials | Typical Thickness / Effect | Common Purpose | Design / Note sulla richiesta di offerta |
|---|---|---|---|---|
| Type II Anodizing | Alluminio | 5-25 micron | Corrosion protection, colore, cosmetic appearance | Confirm color, sigillatura, and masking for threaded or precision-fit areas. |
| Type III Hard Anodizing | Alluminio | 25-60 micron | Wear resistance, harder surface, functional protection | Allow for dimensional growth and confirm critical tolerance areas before production. |
| Nichelatura chimica | Steel, alluminio, copper alloys | 5-50 micron | Uniform coating, resistenza alla corrosione, resistenza all'usura | Useful for complex geometry; confirm coating thickness and post-treatment requirements. |
| Passivazione | Acciaio inossidabile | No meaningful buildup | Improves stainless corrosion resistance | Suitable when dimensional change must be minimized. Confirm stainless grade and standard requirement. |
| Sabbiatura delle perle | Alluminio, acciaio inossidabile, acciaio, ottone | Surface texture change | Uniform matte appearance, visual consistency | Cosmetic expectations should be confirmed with sample photos or finish references. |
| Verniciatura a polvere | Alluminio, acciaio | 60-120 micron | Outdoor durability, colore, protective coating | Mask threads, buchi, grounding surfaces, and precision assembly features. |
| Black Oxide | Steel | 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. |
| Marcatura laser | Most metals and some plastics | Local surface marking | Part identification, logos, traceability marks | Confirm marking position, misurare, contrast, and whether the mark is cosmetic or functional. |

Surface Finishing FAQ for CNC Machined Parts
JADE-CNC can review anodizing, hard coat anodizing, placcatura, passivazione, lucidatura, brushing, sabbiatura, pittura, verniciatura a polvere, ossido nero, trattamento termico, laser marking, and other finish requirements based on drawing and material.
The finish should be selected according to material, funzione, aspetto, corrosion exposure, wear requirement, conductivity, masking areas, tolerance impact, e le esigenze di ispezione.
SÌ. Anodizing can add coating thickness and may affect precision-fit areas, discussioni, buchi, and mating surfaces. 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.
SÌ. Passivation is commonly used for stainless steel parts to improve corrosion resistance without meaningful dimensional buildup.
SÌ. Masking areas such as threads, buchi, electrical contact surfaces, sealing faces, and tight-tolerance features should be reviewed before finishing.
Color can vary depending on material grade, condizione della superficie, lotto, coating process, and supplier conditions. Color expectations should be confirmed with references or samples when appearance is important.
Common checks include visual appearance, spessore del rivestimento, roughness, masking condition, dimensioni critiche, thread fit, and functional surfaces.
Some plastic parts can be polished, bead blasted, painted, marked, or treated depending on the material and application. The finish method should be reviewed case by case.
Please provide drawings, grado del materiale, quantità, required finish, color or texture reference, masking areas, dimensioni critiche, appearance requirements, and inspection documents if needed.
