Cutting Condition
| Conventional conditions (use machining center spindle) | Nakanishi's proposed conditions (use 150,000 min-1 turbine spindle) | |
|---|---|---|
| Cutting speed | 57 m/min | 283 m/min |
| Rotation speed | 30,000 min⁻¹ | 150,000 min⁻¹ |
| Feed speed | 800 mm/min | 2,000 mm/min |
| Feed | 0.011 mm/tooth | 0.007 mm/tooth |
| Cutting depth ap | 0.005 mm | 0.005 mm |
| Processing time | 1 h 26 min 18 sec | 37 min 56 sec |
Point
Nakanishi spindle (150,000 min-1 turbine spindle for machining centers: HTS1500ZZ-M2040) achieves high-precision and high-speed milling with small-diameter end mill.
Compared to the machining center spindle (conventional conditions), the high-speed rotation has increased the feed rate by 2.5 times, resulting in a 56% reduction in processing time!
