Overview
The Nakamura-Tome SC-100X2 is a small two-spindle turn-mill center in which both spindles run to 6,000 RPM: an 11/7.5 kW (15/10 hp) left spindle with a 6 inch chuck and 51 mm bar capacity, and a 7.5/5.5 kW (10/7.4 hp) right spindle with a 5 inch chuck and 42 mm bar capacity. Turning diameter is 195 mm (7.7 in) and turning length 400 mm (15.7 in).
The right spindle is not fixed in place. It rides on its own slide, listed at 150 mm (5.9 in) of X travel, and the distance between the spindles ranges from min. 200 mm (7.9 in) to max. 600 mm (23.6 in). A right spindle that moves in X as well as along the bed can position the part against a tool rather than only meeting the left spindle on centerline, which gives the programmer more ways to work both spindles at the same time.
Milling is handled by a 7.1/2.2 kW motor at 6,000 RPM, with a Y-axis stroke of 80 mm (+/-40 mm). That is enough for cross holes, tapped holes and flats on the small parts this machine is sized for. The right spindle's chuck can be upgraded from 5 inch to 6 inch, matching the left side when both ends of a part need the same grip.
The trade against the SC-100 is diameter for speed: the SC-100X2 turns 195 mm (7.7 in) against 230 mm (9.1 in) on the SC-100, but runs its left spindle to 6,000 RPM where the SC-100 stops at 5,000 rpm. The footprint is 3,072 × 1,973.7 × 1,799 mm (W × D × H).

Strengths & Limitations
Strengths
- Both spindles run to 6,000 RPM, so small diameters reach cutting speed on either side
- Right spindle travels on its own slide with 150 mm (5.9 in) of X
- Spindle-to-spindle distance from min. 200 mm (7.9 in) to max. 600 mm (23.6 in)
- Y-axis stroke of 80 mm (+/-40 mm) with a 7.1/2.2 kW milling motor at 6,000 RPM
- Footprint of 3,072 × 1,973.7 × 1,799 mm (W × D × H)
Limitations
- Turning diameter is 195 mm (7.7 in), smaller than the 230 mm (9.1 in) of the SC-100
- Bar capacity is 51 mm on the left spindle and 42 mm on the right
- Right spindle is rated 7.5/5.5 kW (10/7.4 hp), so heavy cuts belong on the left spindle
- Right chuck is 5 inch as standard; the 6 inch chuck is an option

Frequently Asked Questions
01
Both run to 6,000 RPM. The left is rated 11/7.5 kW (15/10 hp) with a 6 inch chuck and 51 mm bar capacity. The right is rated 7.5/5.5 kW (10/7.4 hp) with a 5 inch chuck, 6 inch as an option, and 42 mm bar capacity.
02
The SC-100 turns 230 mm (9.1 in) in diameter and its left spindle tops out at 5,000 rpm. The SC-100X2 turns 195 mm (7.7 in), runs both spindles to 6,000 RPM and puts its right spindle on a slide with 150 mm (5.9 in) of X travel. Both list 400 mm (15.7 in) of turning length.
03
The milling motor is listed at 7.1/2.2 kW at 6,000 RPM, and the Y-axis stroke is 80 mm (+/-40 mm). That supports cross drilling, tapping and flats on small parts. The table does not give a turret station count.
04
The distance between spindles is listed as max. 600 mm (23.6 in) and min. 200 mm (7.9 in). The right spindle moves within that range, so it can close in on short parts for the handover and back off for longer ones.
05
The footprint is 3,072 × 1,973.7 × 1,799 mm (W × D × H). Leave room at the left end for a bar feeder if you plan to use the 51 mm bar capacity, and for chip removal at the side.
