Brass CNC turned parts are widely used in industries such as automotive, electronics, fluid control, and EV charging systems due to their excellent machinability, corrosion resistance, and electrical conductivity. Understanding the complete manufacturing process helps buyers and engineers ensure consistent quality and cost efficiency.
Brass CNC turned parts are precision components manufactured using CNC turning machines, where a brass workpiece rotates while cutting tools shape it into the desired geometry.
Common applications include:
Different brass grades affect machining performance and final part quality.
| Brass Grade | Key Features | Typical Applications |
|---|---|---|
| H62 / C28000 | Good strength, cost-effective | General machining parts |
| H65 / C27000 | Balanced ductility & strength | Connectors, fittings |
| C36000 | Free-cutting, high efficiency | High-volume CNC turning |
| C37700 | Good forging properties | Valve components |
Brass bars (round or hex) are selected based on part design and tolerance requirements. Material certification ensures consistency.
Engineers convert CAD drawings into CNC programs (G-code), defining:
The brass bar rotates at high speed while cutting tools remove material to form the part.
Key operations include:
Complex parts may require additional processes:
| Process | Purpose |
|---|---|
| Milling | Add slots or flats |
| Drilling | Deep or cross holes |
| Tapping | Internal threads |
| Deburring | Remove sharp edges |
Surface treatment enhances performance and appearance.
| Finishing Type | Benefit |
|---|---|
| Polishing | Smooth surface, improved aesthetics |
| Nickel Plating | Corrosion resistance |
| Chrome Plating | Wear resistance |
| Passivation | Anti-oxidation protection |
Precision is critical in CNC turned brass parts.
