How much does the Niles-Simmons N40 MC cost?
Estimated price range
Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Niles-Simmons. Configuration moves it a long way.
Overview
The Niles-Simmons N40 MC is the long-bed member of the MC mill-turn family: a 1,100 mm swing with turning lengths of 2,500, 3,500, 5,000, 6,500, 8,000 or 9,500 mm. No other MC machine reaches as far, with the N60 MC ending at 7,500 mm and the N20 MC at 3,500 mm.
The main spindle has an A15 (DIN 55026) nose, a 160 mm bore and a 240 mm bearing diameter. Niles-Simmons lists two drive variants at 60% | 100% duty cycle: 80 | 71 kW and 87 | 78 kW, with torque of 3,800 | 3,400 Nm and 8,000 | 7,230 Nm and speed ranges of 0 – 1,000 rpm and 0 – 1,750 rpm. The table gives these as separate rows and does not tie a torque to a speed range, so the pairing should be confirmed. The same applies to the C axis, listed as 0 – 100 rpm and 0 – 50 rpm.
Milling geometry is where this model stands apart. The B axis swivels from -15 to +195 degrees, and Y travel is symmetric at -350 to +350 mm. Two milling spindles are listed on HSK-T 100 or Capto C8 (PSC 80) tooling: 53 | 50 kW with 653 | 497 Nm, and 50 | 46 kW with 446 | 320 Nm, at 40% | 100% duty cycle, with top speeds of 5,000 rpm and 8,000 rpm. Following the order of the rows, the higher-torque spindle is the 5,000 rpm one and the lighter one reaches 8,000 rpm.
Rapids are 30 | 20 | 30 m/min in X, Y and Z, and X travel is -30 to +1,065 mm. The magazine comes in 48, 72, 96, 120 or 144 pockets with a 25 kg tool weight limit. The tailstock has an MK 6 centre, a 180 mm quill with 170 mm of travel and a clamping force of 4 – 30 kN. Depending on bed length the machine is 9,655 to 17,055 mm long and weighs 55 to 85 t, and it runs on SINUMERIK ONE.

Strengths & Limitations
Strengths
- Turning lengths up to 9,500 mm, the longest in the MC family, on a 1,100 mm swing
- B axis swivels from -15 to +195 degrees
- Symmetric Y travel of -350 to +350 mm for off-centre milling on either side of the spindle axis
- Choice of milling spindle, 5,000 rpm or 8,000 rpm, on HSK-T 100 or Capto C8 (PSC 80) tooling
- Main spindle torque listed up to 8,000 | 7,230 Nm at 60% | 100% duty cycle
- Rapids of 30 | 20 | 30 m/min in X, Y and Z, against 12 | 12 | 24 m/min on the N60 MC
Limitations
- Main spindle torque peaks at 8,000 | 7,230 Nm; the N60 MC lists up to 15,000 | 13,030 Nm
- Only one spindle nose is listed, A15 with a 160 mm bore; the N60 MC also offers A20 with a 225 mm bore
- The longest version is 17,055 mm long and weighs 85 t, which sets real demands on floor space and foundation
- Tailstock clamping force is 4 – 30 kN, below the 5 – 35 | 8 – 55 kN listed for the N60 MC
