How much does the Nakamura-Tome SC-300L2 cost?
Estimated price range
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 SC-300L2 is a long-bed turn-mill center for chucker and shaft work, with a 360 mm (14.2 in) maximum turning diameter, 1,135 mm (44.7 in) of turning length and a 22 / 18.5 kW left spindle that runs to 3,500 rpm. It takes 10 in or 12 in chucks.
Length is what sets this model apart. Nakamura-Tome lists 1,310 mm (51.6 in) between spindles and 1,213.5 mm (47.8 in) between centers, so long parts can be supported at both ends rather than cantilevered from the chuck. For comparison, the SC-300II lists 635 mm (25 in) of turning length on the same 360 mm (14.2 in) diameter, 3,500 rpm and 22 / 18.5 kW, so the L2 is the choice when the part is longer than that.
Bar capacity is 71 mm (2.8 in) as standard and 89 mm (3.5 in) with the Ø89 mm option. Combined with the 3,500 rpm ceiling and the 10 in or 12 in chucks, the spindle is set up for larger-diameter steel parts at moderate speed, not small-diameter work that needs high surface speed on a thin bar.
Rotary tools run on a 7.5 / 3.7 kW milling spindle at up to 6,000 rpm, enough for cross-drilling, tapping, flats and keyways on shafts. The table on this model's page gives no turret station count or Y-axis travel. The SC-300IIL lists the same 1,135 mm (44.7 in) turning length and 360 mm (14.2 in) diameter with 12 turret stations and +/- 60 mm (+/- 2.36 in) of Y, but those figures belong to the SC-300IIL; confirm the SC-300L2's own turret and Y specification before ordering. The machine occupies 4,902 × 2,130 × 2,300 mm (W × D × H).

Strengths & Limitations
Strengths
- 1,135 mm (44.7 in) of turning length and 1,213.5 mm (47.8 in) between centers for long shafts
- 360 mm (14.2 in) maximum turning diameter with 10 in or 12 in chucks
- 22 / 18.5 kW left spindle drive for heavier turning in steel
- Bar capacity of 71 mm (2.8 in), or 89 mm (3.5 in) with the Ø89 mm option
- 7.5 / 3.7 kW milling spindle at up to 6,000 rpm for cross-drilling and keyways
Limitations
- Spindle speed tops out at 3,500 rpm, which limits surface speed on small diameters
- The page's table lists no turret station count or Y-axis travel, so both need confirming with Nakamura-Tome
- 89 mm (3.5 in) bar needs the Ø89 mm option; standard capacity is 71 mm (2.8 in)
- Needs a 4,902 × 2,130 mm floor area, long for a machine of this swing

Frequently Asked Questions
01
Maximum turning length is 1,135 mm (44.7 in). Nakamura-Tome lists 1,213.5 mm (47.8 in) between centers and 1,310 mm (51.6 in) between spindles, so a long shaft can be held at both ends while it is turned.
02
Mainly in length. The SC-300II lists 635 mm (25 in) of turning length; the SC-300L2 lists 1,135 mm (44.7 in). Both turn 360 mm (14.2 in) in diameter, run to 3,500 rpm on 22 / 18.5 kW and take 10 in or 12 in chucks.
03
71 mm (2.8 in) as standard. The Ø89 mm option raises bar capacity to 89 mm (3.5 in). For chucked work the machine takes a 10 in or 12 in chuck and turns up to 360 mm (14.2 in) in diameter.
04
A milling spindle rated 7.5 / 3.7 kW at up to 6,000 rpm. That covers cross-holes, tapping, flats and keyways on shafts. The page's table gives no Y-axis travel for this model, so off-centre milling should be confirmed before quoting such work.
