Surface Finishing of Precision CNC Machining
La finition des surfaces est un élément important de l'usinage CNC de précision. Elle apporte vivacité, résistance à la corrosion, à l'usure et aspect physique avec des capacités dimensionnelles proches. Les options de finition de surface les plus couramment utilisées pour les composants de précision sont présentées ci-dessous.
The first machining of CNC where the tool imprints can still be seen on the surface. This coating is applied to useful items that need accuracy and appearance is not critical.
Prior to proceeding to additional finishing processes, sharp edges and burrs which arise during machining are eliminated to enhance safety, accuracy and surface quality.
The section is also washed exhaustively to eliminate the oil, coolant, dust, and contaminants. When properly cleaned, adhesion and even finishing result is guaranteed.
The surface is ready as per the needed finish. This can be through light sanding, grinding or pre-treatment so that the results can be uniform.
Blasting, brushing or polishing of the bead is done to enhance the texture, smoothness or physical looks.
In order to increase corrosion resistance, wear resistance, and durability, protective or decorative treatments are used, such as anodizing, powder coating, passivation, or plating.
Manufactured components are checked on roughness on the surface, the thickness of the coating, color uniformity, and precision to check that they are within specification.
On inspection, protective steps may be taken using anti-corrosion oil, protective film, or temporary coating that ensures that the quality of the surface remains good during its storage or transportation.

| Hole Size & Depth | • Minimum hole diameter: Ø1.0 mm
• Min depth: Ø2.0 mm (depends on tool availability)
• Recommended depth: ≥ tool diameter to stabilize chip evacuation |
| Sous-coupes | • Supported: Square, flat faces, dovetails, and custom profiles
• Specialized tools may increase machining time or cost |
| Heat & Burnishing | • CNC Milling: Minimum Ø5 mm with Ø4 mm depth
• Turned parts: Fine finishing laser engraving is preferred |
