Overview

The Nakamura-Tome SC-100 is a 6 in chuck turn-mill center offered in two layouts, one with a sub-spindle and one with a tailstock. Turning diameter is 230 mm (9.1 in) in both; turning length and Z travel are 400 mm (15.7 in) in the standard sub-spindle build and 300 mm (11.8 in) with the tailstock.

That choice is the main decision. The sub-spindle runs to 6,000 rpm on a 7.5 / 5.5 kW drive and sits 600 mm (23.6 in) from the left spindle, so a part cut off from bar can be picked up and finished on its back face in the same cycle. The tailstock build gives up that second spindle and some Z travel, but supports slender work between centers, with 430 mm (16.9 in) listed between centers. Parts that need both ends machined favor the sub-spindle; long thin pins that whip under cutting load favor the tailstock.

The left spindle is rated 11 / 7.5 kW and runs to 5,000 rpm, with 51 mm (2 in) bar capacity. Milling comes from a 7.1/2.2 kW motor, and the Y-axis stroke is 80 mm (+/-40 mm), enough for cross holes, flats and short slots on parts of this size.

One listed detail is easy to miss: lubrication oil recovery is 100% standard. Keeping way oil out of the coolant slows the build-up of tramp oil in the tank, which matters on a small machine running long unattended bar jobs. The table gives a height of 1,780mm but no width or depth, so ask for the layout drawing.

Strengths & Limitations

Strengths

230 mm (9.1 in) turning diameter on a 6 in chuck
Sub-spindle at 6,000 rpm and 7.5 / 5.5 kW for back-side work in the standard build
80 mm (+/-40 mm) Y-axis stroke with a 7.1/2.2 kW milling motor
Lubrication oil recovery listed as 100% standard
Tailstock layout available for slender work, with 430 mm (16.9 in) between centers

Limitations

Left spindle tops out at 5,000 rpm, below the 6,000 RPM of the SC-100X2
Bar capacity is 51 mm (2 in), which rules out larger bar stock
The tailstock build shortens Z travel and turning length to 300 mm (11.8 in) and has no sub-spindle
Left spindle is rated 11 / 7.5 kW, which limits heavy roughing in tough materials

Best For

Small bar parts up to 51 mm (2 in) Two-sided parts finished on the 6,000 rpm sub-spindle Slender pins supported by the tailstock Small parts with flats or cross holes within 80 mm of Y

Frequently Asked Questions

01 Should I choose the sub-spindle or the tailstock version of the SC-100?

The sub-spindle build gives 400 mm (15.7 in) of Z travel and turning length and a 6,000 rpm, 7.5 / 5.5 kW second spindle for back-working. The tailstock build gives 300 mm (11.8 in) and supports slender parts between centers, with 430 mm (16.9 in) listed between centers. Parts that need both ends machined favor the sub-spindle.

02 How does the SC-100 differ from the SC-100X2?

The SC-100 turns 230 mm (9.1 in) in diameter against 195 mm (7.7 in) on the SC-100X2. The SC-100X2 runs its left spindle to 6,000 rpm, where the SC-100 stops at 5,000 rpm. Both list 400 mm (15.7 in) of turning length and a 7.5 / 5.5 kW second spindle at 6,000 rpm.

03 What milling capacity does the SC-100 have?

The milling motor is rated 7.1/2.2 kW, and the Y-axis stroke is 80 mm (+/-40 mm). That covers cross holes, tapped holes and flats on small parts. The table does not list turret stations or a driven-tool speed.

04 How tall is the SC-100 and how much space does it need?

The table lists a height of 1,780mm but no width or depth. Ask Nakamura-Tome for the layout drawing, and allow room for a bar feeder if you plan to run the full 51 mm (2 in) bar capacity.
