How much does the Nakamura-Tome JX-50 cost?

Price estimate

Uncertain

We do not have a price for the Nakamura-Tome JX-50 that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.

Overview

The Nakamura-Tome JX-50 is a small turn-mill center built around a 30,000 rpm tool spindle, the NT Smart Cube, with a 60-tool magazine (119 optional) and a 3.3 s chip-to-chip tool change. Its left and right spindles both run to 6,000 rpm on 11 kW / 7.5 kW (14.8 hp / 10.1 hp) motors, take 42 mm (1.7 in) bar, and use 5 in or 6 in chucks.

Turning diameter depends on which tool does the cutting: 280 mm (11.0 in) with the tool spindle and 220 mm (8.7 in) with the lower turret. Turning length is 650 mm (25.6 in). The tool spindle unit is 299 mm (11.8 in) long, a figure that matters when a long drill or holder has to reach a feature close to the chuck or the opposite spindle.

The spindle speed sets the character of this machine. A 30,000 rpm tool spindle runs small end mills, engraving tools and micro drills at the speeds they need, while 11 kW / 7.5 kW (14.8 hp / 10.1 hp) on each work spindle is enough for the 42 mm (1.7 in) bar this machine is sized for. Heavy roughing of large stock belongs on a bigger machine such as the JX-200, which is listed at 325 mm (12.8 in) / 255 mm (10 in) of turning diameter and 1,058 mm (41.7 in) of length.

The frame measures 4,264.4 mm W x 2,378 mm D x 2,250 mm H (167.9 x 93.6 x 88.6 in), or 2,530.5 mm high to the top of the indicator light. The body itself occupies 3,000 x 2,000 mm (118.1 x 78.7 in) without the chip tank and conveyor, and the spindle centre sits 450 mm (17.7 in) from the front of the machine, which keeps loading and setup within an operator's reach.

Strengths & Limitations

Strengths

NT Smart Cube tool spindle running to 30,000 rpm for small cutters and fine features
60-tool magazine as standard, 119 optional, with a 3.3 s chip-to-chip change
Left and right spindles both run to 6,000 rpm on 11 kW / 7.5 kW (14.8 hp / 10.1 hp)
Spindle centre only 450 mm (17.7 in) from the machine front for easy loading and setup
Body footprint of 3,000 x 2,000 mm (118.1 x 78.7 in) excluding chip tank and conveyor

Limitations

Bar capacity is 42 mm (1.7 in) on both spindles, so larger stock needs a different machine
Chucks are limited to 5 in or 6 in
With the lower turret the turning diameter falls to 220 mm (8.7 in), against 280 mm (11.0 in) with the tool spindle
11 kW / 7.5 kW (14.8 hp / 10.1 hp) per work spindle limits heavy roughing

Best For

Small, complex bar parts up to 42 mm (1.7 in) finished in one setup Micro drilling and small end mill work at up to 30,000 rpm High-mix work that needs many tools loaded at once, up to 119 with the option Parts up to 650 mm (25.6 in) long with milled features on both ends

Frequently Asked Questions

01 What is the NT Smart Cube on the JX-50?

It is the JX-50's tool spindle unit, listed at 299 mm (11.8 in) long and running to 30,000 rpm. It is fed from a 60-tool magazine (119 optional) with a 3.3 s chip-to-chip change, and with it the machine turns up to 280 mm (11.0 in) in diameter.

02 Why are two turning diameters listed for the JX-50?

The figure depends on the tool doing the cutting. With the tool spindle the maximum is 280 mm (11.0 in); with the lower turret it is 220 mm (8.7 in). Plan large-diameter turning on the tool spindle, or keep parts under 220 mm (8.7 in) if both tools must reach them.

03 What bar and chuck sizes does the JX-50 take?

Both the left and right spindles take bar up to 42 mm (1.7 in), run to 6,000 rpm and are rated 11 kW / 7.5 kW (14.8 hp / 10.1 hp). Chucks are 5 in or 6 in. Turning length is 650 mm (25.6 in).

04 How much space does the JX-50 need?

Overall it measures 4,264.4 mm W x 2,378 mm D x 2,250 mm H (167.9 x 93.6 x 88.6 in), and 2,530.5 mm high to the indicator light. The machine body alone is 3,000 x 2,000 mm (118.1 x 78.7 in) without the chip tank and conveyor, so allow for those when planning the floor.
