Comprehensive CNC brass machining handbook covering cutting speeds Vc, feed rates, tooling rake angles, chip formation, and coolant selection.
| Machining Operation | Tool Substrate | Cutting Speed Vc (m/min) | Feed Rate f (mm/rev) | Tool Geometry & Rake Angle |
|---|---|---|---|---|
| Swiss CNC Turning | Uncoated / TiN Carbide | 180 – 350 m/min | 0.05 – 0.25 mm/rev | Positive rake angle (0° to +5°) |
| High-Speed Drilling | Solid Carbide / HSS-Co | 80 – 160 m/min | 0.03 – 0.15 mm/rev | 118° - 135° point angle, polished flutes |
| Thread Rolling | HSS Hardened Dies | 30 – 70 m/min | Pitch-matched | Forming dies (No chips produced) |
| Diamond Knurling | HSS Form Wheels | 25 – 60 m/min | 0.10 – 0.30 mm/rev | High-pressure oil stream lubrication |
