Tool Material Comparison
| Material | Best For | Speed | Durability |
|---|---|---|---|
| Carbide | High-speed machining | ★★★★★ | ★★★★☆ |
| PCD (Diamond) | Non-ferrous metals | ★★★★☆ | ★★★★★ |
| High-Speed Steel | Cost-effective drilling | ★★★☆☆ | ★★★☆☆ |
Pro Tip: Carbide tools excel in Precision Machining for aerospace.
Coatings: The Secret to Long-Lasting Tools
- TiN (Titanium Nitride): Reduces friction in CNC Turning.
- Diamond Coating: For abrasive composites in New Energy projects.
Stat: TiAlN-coated tools last 3x longer in high-heat environments.
How to Choose the Right CNC Tool
- Material Matters: Hard metals need carbide; plastics suit HSS.
- Operation Type: Milling vs. turning? Match the tool.
- Surface Finish: Ball nose mills for smooth contours.
