A well-known manufacturer, mainly processing copper, required holes of diameters 6, 8, 10, 12, and 14 mm. The Φ12.0 mm through-hole posed particularly high output demands, leading to significant tool consumption. The customer needed a drill with longer life. So how did we extend tool life without sacrificing efficiency or accuracy? Let's look at the results.
Machining Setup:
| Machine Type | Machining Center | Model | 850 | ||
| Spindle power | about 11kw | Spindle interface | BT40 | CNC system | Fanuc |
| Cooling method: | external cooling | cooling pressure | 2-5 bar | rotation accuracy | 0.02mm |
| Processed material | H3 brass | hardness | HB200 | drilling thickness | 12.5mm |
Both our drill and a competitor's solid carbide drill were tested under the same fixed machine parameters for a fair performance comparison
