Drilling Data
| Coolant through Drilling (CTS-2630 / EM-3030T-J) | Conventional Drilling (NR-3060S / EM-3060J) | |
|---|---|---|
| Work material | S50C (carbon steel) | S50C (carbon steel) |
| Tool diameter | 1.0 mm | 1.0 mm |
| Hole depth | 20 mm through hole | 20 mm through hole |
| L/D | 20 | 20 |
| Cutting speed | 94 m/min | 31 m/min |
| Rotating speed | 30,000 min⁻¹ | 10,000 min⁻¹ |
| Feed rate | 0.03 mm/rev | 0.01 mm/rev |
| Feed speed | 900 mm/min | 100 mm/min |
| Coolant | Internal Iubrication | External coolant |
| Peck drilling cycle | No pecking | 0.5 mm |
| Processing time | 1.3 sec/hole = 8 min for 360 holes | 45 sec/hole = 4.5 h for 360 holes |
Point
Drilled 360 holes without drill breakage.Processing time that used to take 4.5 hours at 45 seconds per hole, it has been reduced to 8 minutes at 1.3 seconds per hole, an amazing reduction in time!
Non-peck drilling by the coolant through spindle reduces processing time by 97%.
