Surface Finish Selection Reference for CNC Parts
Surface finishing affects the appearance, 耐食性, 摩耗性能, 導電率, and assembly fit of CNC machined parts. JADE-CNC can review the drawing, 材料, 許容範囲, cosmetic requirement, and application environment before recommending a suitable finish.
| 表面仕上げ | Suitable Materials | Typical Thickness / Effect | Common Purpose | Design / RFQ Notes |
|---|---|---|---|---|
| Type II Anodizing | アルミニウム | 5-25 ミクロン | Corrosion protection, 色, cosmetic appearance | Confirm color, 封印, and masking for threaded or precision-fit areas. |
| Type III Hard Anodizing | アルミニウム | 25-60 ミクロン | Wear resistance, harder surface, functional protection | Allow for dimensional growth and confirm critical tolerance areas before production. |
| 無電解ニッケルめっき | Steel, アルミニウム, 銅合金 | 5-50 ミクロン | Uniform coating, 耐食性, 耐摩耗性 | Useful for complex geometry; confirm coating thickness and post-treatment requirements. |
| 不動態化 | ステンレス鋼 | No meaningful buildup | Improves stainless corrosion resistance | Suitable when dimensional change must be minimized. Confirm stainless grade and standard requirement. |
| ビーズブラスト | アルミニウム, ステンレス鋼, 鋼鉄, 真鍮 | Surface texture change | Uniform matte appearance, visual consistency | Cosmetic expectations should be confirmed with sample photos or finish references. |
| 粉体塗装 | アルミニウム, 鋼鉄 | 60-120 ミクロン | Outdoor durability, 色, protective coating | Mask threads, 穴, 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. |
| レーザーマーキング | Most metals and some plastics | Local surface marking | Part identification, logos, traceability marks | Confirm marking position, サイズ, contrast, and whether the mark is cosmetic or functional. |

Request a CNC Surface Finishing Review
Send your drawing, 材質グレード, surface finish requirement, color or texture reference, マスキング領域, 限界寸法, 検査の必要性, and target quantity. JADE-CNC will review whether the requested finish is suitable for the part material, 幾何学, 許容範囲, and application.
Surface Finishing FAQ for CNC Machined Parts
JADE-CNCは陽極酸化処理をレビューできます, hard coat anodizing, メッキ, 不動態化, 研磨, ブラッシング, ビーズブラスト, 絵画, 粉体塗装, 黒色酸化物, 熱処理, レーザーマーキング, and other finish requirements based on drawing and material.
The finish should be selected according to material, 関数, 外観, 腐食にさらされる, wear requirement, 導電率, マスキング領域, 許容誤差への影響, 検査の必要性.
はい. Anodizing can add coating thickness and may affect precision-fit areas, スレッド, 穴, 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.
はい. Passivation is commonly used for stainless steel parts to improve corrosion resistance without meaningful dimensional buildup.
はい. Masking areas such as threads, 穴, electrical contact surfaces, sealing faces, and tight-tolerance features should be reviewed before finishing.
Color can vary depending on material grade, 表面状態, バッチ, coating process, and supplier conditions. Color expectations should be confirmed with references or samples when appearance is important.
Common checks include visual appearance, コーティングの厚さ, roughness, masking condition, 限界寸法, ねじのはめあい, 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, 材質グレード, 量, required finish, color or texture reference, マスキング領域, 限界寸法, appearance requirements, and inspection documents if needed.
