Overview

The Nakamura-Tome Super NTJ is a compact twin-spindle turn-mill center with a 182 deg B-axis range, 90 mm of Y-axis travel and up to 48 tool stations. It turns parts up to 190 mm (7.5 in) in diameter and 620 mm (24.4 in) long, on a 6 in chuck with an 8 in chuck optional.

The B-axis is the feature to plan around. A 182 deg swivel range lets angled holes and faces be machined in the same cycle as the turning, instead of in a second setup on a mill. The milling drive behind it is rated 5.5/3.7 kW at 6,000 RPM, so the strength is in drilling, tapping and contour milling at moderate speed rather than heavy face milling.

The left spindle is the larger of the two: 15/11 kW, 65 mm (2.6 in) bar as standard and 4,500 rpm. Unusually, the bore option goes down rather than up. With the Ø51 mm option the left spindle takes 51 mm (2 in) bar but runs to 5,000 rpm, which suits shops whose work is mostly small-diameter bar. The right spindle is rated 11/7.5 kW at 5,000 RPM and also takes 51 mm (2 in) bar, so a part cut from 65 mm stock needs a check that the right spindle can grip it for the second operation.

Against its neighbours, the NTY3-100V offers up to 72 stations and 200 mm (7.9 in) of turning diameter, while the Super NTJ has fewer stations but the B-axis. The NTJ-100 turns 175 mm (6.9 in) by 678 mm (26.7 in) on an 11 / 7.5 kW spindle. The Super NTJ occupies 3,660 × 2,320 × 2,170 mm (W × D × H). The NTY3-150V, by comparison, is 4,244.2 mm wide.

Strengths & Limitations

Strengths

182 deg B-axis range for angled holes and faces in the same setup
90 mm of Y-axis travel for off-centre drilling and milling
Up to 48 tool stations, room for several part families to stay set up
Left spindle takes 65 mm (2.6 in) bar as standard on a 15/11 kW motor
Compact 3,660 × 2,320 × 2,170 mm (W × D × H) footprint

Limitations

Up to 48 stations, against up to 72 on the NTY3-100V
The right spindle takes 51 mm (2 in) bar and is rated 11/7.5 kW, smaller than the left
Milling drive rated 5.5/3.7 kW at 6,000 RPM limits heavy milling and small-tool speed
Turning diameter stops at 190 mm (7.5 in); an 8 in chuck is an option

Best For

Parts with angled holes or faces that need the 182 deg B-axis Bar work up to 65 mm (2.6 in) on the left spindle Two-end machining of parts within 190 mm (7.5 in) diameter Shops short of floor space

Frequently Asked Questions

01 What does the B-axis on the Super NTJ do?

It swivels through a 182 deg range, so drilling and milling can be done at an angle to the spindle axis without a second setup. Combined with 90 mm of Y-axis travel and a 5.5/3.7 kW milling drive at 6,000 RPM, it lets angled features be finished in the turning cycle.

02 What does the Ø51 mm spindle option change?

The standard left spindle takes 65 mm (2.6 in) bar and runs to 4,500 rpm. The Ø51 mm option reduces bar capacity to 51 mm (2 in) and raises top speed to 5,000 rpm. Shops running mostly small bar gain surface speed; shops running large bar keep the standard spindle.

03 Are the two spindles of the Super NTJ the same size?

No. The left spindle is rated 15/11 kW and takes 65 mm (2.6 in) bar as standard. The right spindle is rated 11/7.5 kW at 5,000 RPM and takes 51 mm (2 in) bar, so check second-operation gripping on parts made from the largest stock.

04 How does the Super NTJ compare with the NTJ-100?

The NTJ-100 turns 175 mm (6.9 in) in diameter and 678 mm (26.7 in) long with an 11 / 7.5 kW spindle at up to 5,000 rpm. The Super NTJ turns 190 mm (7.5 in) by 620 mm (24.4 in) with a 15 / 11 kW left spindle, and adds the 182 deg B-axis.
