CNC Parts Surface Finishing Services
JADE-CNC provides CNC parts surface finishing support for machined metal and plastic components that require corrosion resistance, resistencia al desgaste, color, textura, 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, pasivación, pulido, voladura de cuentas, cuadro, powder coating, black oxide, tratamiento térmico, and laser marking according to the drawing, material, visible surfaces, masking areas, tolerance impact, y necesidades de inspección.

Surface Finish Selection Reference for CNC Parts
Surface finishing affects the appearance, resistencia a la corrosión, rendimiento de desgaste, conductividad, and assembly fit of CNC machined parts. JADE-CNC can review the drawing, material, tolerancia, cosmetic requirement, and application environment before recommending a suitable finish.
| Acabado superficial | Suitable Materials | Typical Thickness / Effect | Common Purpose | Design / RFQ Notes |
|---|---|---|---|---|
| Type II Anodizing | Aluminio | 5-25 micrones | Corrosion protection, color, cosmetic appearance | Confirm color, caza de focas, and masking for threaded or precision-fit areas. |
| Type III Hard Anodizing | Aluminio | 25-60 micrones | Wear resistance, harder surface, functional protection | Allow for dimensional growth and confirm critical tolerance areas before production. |
| Niquelado no electrolítico | Steel, aluminio, copper alloys | 5-50 micrones | Uniform coating, resistencia a la corrosión, resistencia al desgaste | Useful for complex geometry; confirm coating thickness and post-treatment requirements. |
| Pasivación | Acero inoxidable | No meaningful buildup | Improves stainless corrosion resistance | Suitable when dimensional change must be minimized. Confirm stainless grade and standard requirement. |
| Granallado | Aluminio, acero inoxidable, acero, latón | Surface texture change | Uniform matte appearance, visual consistency | Cosmetic expectations should be confirmed with sample photos or finish references. |
| Recubrimiento en polvo | Aluminio, acero | 60-120 micrones | Outdoor durability, color, protective coating | Mask threads, agujeros, 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. |
| Marcado láser | Most metals and some plastics | Local surface marking | Part identification, logos, traceability marks | Confirm marking position, tamaño, contrast, and whether the mark is cosmetic or functional. |

Surface Finishing FAQ for CNC Machined Parts
JADE-CNC can review anodizing, hard coat anodizing, enchapado, pasivación, pulido, brushing, voladura de cuentas, cuadro, powder coating, black oxide, tratamiento térmico, laser marking, and other finish requirements based on drawing and material.
The finish should be selected according to material, función, apariencia, corrosion exposure, wear requirement, conductividad, masking areas, tolerance impact, y necesidades de inspección.
Sí. Anodizing can add coating thickness and may affect precision-fit areas, trapos, agujeros, 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.
Sí. Passivation is commonly used for stainless steel parts to improve corrosion resistance without meaningful dimensional buildup.
Sí. Masking areas such as threads, agujeros, electrical contact surfaces, sealing faces, and tight-tolerance features should be reviewed before finishing.
Color can vary depending on material grade, condición de la superficie, lote, coating process, and supplier conditions. Color expectations should be confirmed with references or samples when appearance is important.
Common checks include visual appearance, espesor del recubrimiento, roughness, masking condition, critical dimensions, 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 material, cantidad, required finish, color or texture reference, masking areas, critical dimensions, appearance requirements, and inspection documents if needed.
