Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from Nakamura-Tome. Configuration moves it a long way.

Overview

The Nakamura-Tome MX-100 is a compact B-axis turn-mill center: a 12,000 RPM tool spindle (20,000 RPM optional) that swivels through 190 deg (+/-95 deg), 210 mm (+/-105 mm) of Y-axis stroke and a 36-tool ATC magazine with 48 or 72 tools optional. It turns up to 305 mm (12 in) in diameter and 834 mm (32.8 in) in length, on 6 in or 8 in chucks.

Both work spindles are rated 11 / 7.5 kW and both run to 6,000 rpm, so the second operation has the same power as the first. Standard bar capacity is 51 mm (2 in). The Ø65 mm option, for the L spindle only, opens it to 65 mm (2.6 in) and 15 / 11 kW, with top speed reduced to 4,500 rpm.

The tool spindle is where the MX-100 differs from the JX-50, whose NT Smart Cube runs to 30,000 rpm with 60 tools standard. The MX-100 trades that speed for a swivelling head: with 190 deg of B-axis and 210 mm of Y, holes and faces at compound angles can be cut on a turned part without a fixture, and the larger 305 mm (12 in) turning diameter and 834 mm (32.8 in) length take bigger parts. For small cutters the 20,000 RPM option is worth considering.

The frame measures 4,350 × 2,795 × 2,662 mm (W × D × H). Spindle power of 11 / 7.5 kW is modest for the 305 mm (12 in) diameter it can swing, so large-diameter roughing in steel will be power-limited; the strength of this machine is complete machining of complex parts rather than heavy stock removal.

Strengths & Limitations

Strengths

B-axis tool spindle with 190 deg (+/-95 deg) of swivel for compound-angle features
210 mm (+/-105 mm) of Y-axis stroke
Tool spindle runs to 12,000 RPM, with 20,000 RPM optional
36-tool magazine standard, 48 or 72 optional
Left and right spindles both 11 / 7.5 kW at 6,000 rpm

Limitations

11 / 7.5 kW per spindle is light for roughing at the full 305 mm (12 in) diameter
Standard bar capacity is 51 mm (2 in); 65 mm (2.6 in) needs the L-only option, which drops speed to 4,500 rpm
B-axis swivel of 190 deg is narrower than the 240 degrees listed for the JX-250
Standard 12,000 RPM tool spindle is slow for very small cutters without the 20,000 RPM option

Best For

Complex turned parts with angled holes, finished in one setup Parts up to 305 mm (12 in) in diameter and 834 mm (32.8 in) long Bar work up to 51 mm (2 in), or 65 mm (2.6 in) with the option Job shops that need many tools loaded, up to 72 with the option

Frequently Asked Questions

01 How far does the MX-100 B-axis swivel?

The B-axis range is 190 deg (+/-95 deg). Combined with 210 mm (+/-105 mm) of Y-axis stroke, that lets the tool spindle reach holes and faces at compound angles without a special fixture.

02 What is the MX-100 tool spindle speed?

12,000 RPM as standard, with a 20,000 RPM option. Tools come from a 36-tool ATC magazine, or a 48- or 72-tool magazine as an option. If most of your milling is with small end mills and drills, the faster option is the one to quote.

03 Are the two MX-100 spindles the same?

Yes as standard. Both are rated 11 / 7.5 kW and both run to 6,000 rpm. Standard bar capacity is 51 mm (2 in). The Ø65 mm option applies to the L spindle only, giving 65 mm (2.6 in) bar and 15 / 11 kW at 4,500 rpm.

04 Should I choose the MX-100 or the JX-50?

The JX-50 is listed with a 30,000 rpm tool spindle, 60 tools standard and 42 mm (1.7 in) bar on both spindles, aimed at small parts. The MX-100 turns 305 mm (12 in) in diameter and 834 mm (32.8 in) long, has a 190 deg B-axis and 210 mm of Y, and suits larger complex parts.
