Overview

The Nakamura-Tome NTY3-150V is a twin-spindle turn-mill center with three turrets with Y-axis and up to 72 tool stations. It turns parts up to Ø225 mm (8.9 in) in diameter and 685 mm (27 in) long. In the standard φ51 (A2-5) build the left and right spindles each run to 6,000 min-1 on a 15/11 kW drive motor, with 6 in or 8 in chucks.

The spindle choice is the decision that shapes this machine. Standard bar capacity is 51 mm (2 in). The Ø65 mm option raises it to 65 mm (2.6 in) and the drive to 18.5 / 11 kW, but top speed falls to 5,000 rpm. The Ø80 mm option, offered on the left spindle only, takes 80 mm (3.1 in) bar on a φ80 (A2-8) nose with a 28 / 15 kW motor and an 8 in chuck, and runs to 4,000 rpm. Because the right spindle does not take that option, a shop planning to run 80 mm stock should check how the part will be gripped after transfer.

Rotary tools are driven by a 7.5/3.7 kW milling motor rated at 10,000 RPM. That speed suits small drills, end mills and thread mills on the bar sizes this machine runs, where a slower tool drive would limit surface speed. Nakamura-Tome also lists a Z-axis crossover of 115 mm.

Within the NTY3 family the NTY3-150V sits between two sizes. The NTY3-100V turns 200 mm (7.9 in) by 588 mm (23.1 in) on a 6 in chuck with 11 / 7.5 kW spindles, so the NTY3-150V adds both envelope and spindle power. The NTY3-250 keeps the 225 mm (8.9 in) turning diameter but moves to an 8 in chuck, 18.5 / 11 kW and 5,000 rpm, and its lower turret reaches 905.5 mm (35.6 in) for longer shafts. The NTY3-150V occupies 4,244.2 × 2,261 × 2,280 mm (W × D × H).

Strengths & Limitations

Strengths

Three turrets with Y-axis and up to 72 tool stations, so both ends of a complex part can be turned, drilled and milled in one cycle
Both spindles reach 6,000 min-1 in the standard φ51 (A2-5) build, quick for small-diameter bar work
Milling motor rated 7.5/3.7 kW at 10,000 RPM for small drills and end mills
Bar capacity scales from 51 mm (2 in) standard to 65 mm (2.6 in), or 80 mm (3.1 in) on the left spindle, as options
The left-spindle Ø80 mm option brings a 28 / 15 kW drive for heavier stock removal

Limitations

Standard bar capacity is 51 mm (2 in); larger bar needs the Ø65 mm or Ø80 mm option, which lowers top speed to 5,000 or 4,000 rpm
The Ø80 mm, 80 mm (3.1 in) bar option is for the left spindle only
Turning diameter stops at Ø225 mm (8.9 in), so larger flanges and discs need a bigger machine
Needs a 4,244.2 × 2,261 mm floor area and 2,280 mm of height before allowing for access and chip handling

Best For

Bar work up to 51 mm (2 in), or 80 mm (3.1 in) with the left-spindle option Complex turned and milled parts finished on both ends in one cycle Parts within Ø225 mm (8.9 in) and 685 mm (27 in) Small-tool drilling and milling at up to 10,000 RPM

Frequently Asked Questions

01 How many turrets and tools does the NTY3-150V have?

Three turrets, all listed with Y-axis, and up to 72 tool stations in total. With two spindles and three turrets, work can run on both spindles at once, which is the reason to choose this layout over a single-turret machine for complex bar parts.

02 What bar sizes can the NTY3-150V run?

51 mm (2 in) in the standard build at 6,000 rpm. The Ø65 mm option takes 65 mm (2.6 in) bar at up to 5,000 rpm with an 18.5 / 11 kW drive. The Ø80 mm option, left spindle only, takes 80 mm (3.1 in) bar at up to 4,000 rpm with a 28 / 15 kW drive and an 8 in chuck.

03 How does the NTY3-150V compare with the NTY3-250?

Both turn up to 225 mm (8.9 in) in diameter and offer up to 72 stations. The NTY3-250 uses an 8 in chuck, 18.5 / 11 kW and 5,000 rpm as standard, and its lower turret reaches 905.5 mm (35.6 in) against 685 mm (27 in) of turning length on the NTY3-150V. The NTY3-150V is the faster machine, at 6,000 rpm standard.

04 What does the NTY3-150V add over the NTY3-100V?

Envelope and power. The NTY3-100V turns 200 mm (7.9 in) by 588 mm (23.1 in) on a 6 in chuck with 11 / 7.5 kW spindles. The NTY3-150V turns Ø225 mm (8.9 in) by 685 mm (27 in), takes a 6 in or 8 in chuck and has 15/11 kW spindles as standard. Both reach 6,000 rpm and list up to 72 stations.

05 How fast are the driven tools on the NTY3-150V?

The milling motor is rated 7.5/3.7 kW at 10,000 RPM. That favours small drills, end mills and thread mills; large face mills and heavy drilling will be limited more by the motor rating than by speed.
