Cutting conditions
| Tool Manufacturer's Recommended Conditions | Nakanishi's Proposed Conditions | |
|---|---|---|
| Cutting rate [m/min] | 63 | 188 |
| Motor speed [min-¹] | 20,000 | 60,000 |
| Feed per revolution [mm/rev] | 0.02 | 0.033 |
| Feed Speed [mm/min] | 400 | 2,000 |
Point
By incorporating the Nakanishi high-speed rotating spindle, feed rates increased fivefold for φ1 × 3 mm drilling (BMF-3160-CTZ) compared to tool manufacturer recommended conditions, enabling significant productivity gains.
