- A20 spindle nose available alongside A15 (DIN 55026)
Verdict
Choose the Niles-Simmons N60 MC for large-diameter shafts, rolls and rotors where roughing torque decides the cycle: its options run to 15,000 | 13,030 Nm and 115 | 100 kW, with an A20 spindle nose. Choose the Niles-Simmons N40 MC for long shafts up to 9,500 mm of turning length and for parts with many positioning moves, where 30 | 20 | 30 m/min rapids count for more than the extra torque. Magazine options and the SINUMERIK ONE control are the same on both.
