Our best estimate for a cnc lathes / turning center in this class — not a quote from Nakamura-Tome. Configuration moves it a long way.

Overview

The Nakamura-Tome SC-300L appears in the listed figures as a large turning center with a 12-inch chuck as standard, 620 mm (24.4 in) of turning diameter over the cross slide and 1,000 mm (39.4 in) between centers. The listed spindle is 22 kW (30 hp) with 1,432 Nm (1,056 ft-lb) of peak torque, a top speed of 3,500 RPM and an A2-8 nose.

The same table gives a 12-station turret with live tooling as an option, 91 mm (3.58 in) bar capacity, rapids of 20 m/min (787 ipm) in X and 24 m/min (945 ipm) in Z, and a machine weight of 9,000 kg (19,842 lb) approx. The maximum chuck diameter row reads 380 mm (15 in) while naming the 12-inch chuck as standard.

Treat these figures with care. Several of them differ sharply from the SC-300IIL, which lists 360 mm (14.2 in) of turning diameter and 1,135 mm (44.7 in) of turning length on a 22 / 18.5 kW spindle. Before relying on the swing, bar capacity or torque above, ask Nakamura-Tome for a specification sheet, and on a used machine check the nameplate and the turret against them.

Strengths & Limitations

Strengths

620 mm (24.4 in) turning diameter over the cross slide in the listed figures
22 kW (30 hp) spindle with 1,432 Nm (1,056 ft-lb) of listed peak torque for heavy roughing
91 mm (3.58 in) bar capacity through an A2-8 spindle nose
1,000 mm (39.4 in) between centers for shaft work

Limitations

Top spindle speed of 3,500 RPM limits small-diameter work
Live tooling is listed as an option on the 12-station turret
The listed figures differ from the 360 mm (14.2 in) turning diameter of the SC-300IIL, so the specification needs confirming before purchase

Best For

Heavy chucked work in a 12-inch chuck Shafts up to 1,000 mm (39.4 in) between centers Large bar work up to 91 mm (3.58 in)

Frequently Asked Questions

01 How large a part can the SC-300L turn?

The listed figures give 620 mm (24.4 in) of turning diameter over the cross slide and 1,000 mm (39.4 in) between centers, with a 12-inch chuck as standard. Confirm these with Nakamura-Tome before planning work around them.

02 What spindle does the SC-300L have?

The table lists 22 kW (30 hp), 1,432 Nm (1,056 ft-lb) of peak torque, a top speed of 3,500 RPM and an A2-8 spindle nose. Bar capacity is listed as 91 mm (3.58 in).

03 How does the SC-300L relate to the SC-300IIL?

The SC-300IIL lists 360 mm (14.2 in) of turning diameter, 1,135 mm (44.7 in) of turning length, a 22 / 18.5 kW spindle at 3,500 rpm and a 12-station turret. The SC-300L figures on this page differ in swing and length, so treat them as unconfirmed until checked against a specification sheet or the machine itself.

04 How heavy is the SC-300L?

The table gives 9,000 kg (19,842 lb) approx. Check floor loading and rigging access before delivery, and confirm the weight for the specific machine.
