Overview

The Nakamura-Tome SC-450L is a large, long turning center built around a 30 / 22 kW spindle and a 12 in chuck: 480 mm (18.9 in) of turning diameter, 1,520 mm (59.8 in) of turning length and 1,752 mm (69 in) between centers. Top speed is 2,500 rpm, which places it on large-diameter work where cutting speed is reached at low rpm.

Next to the SC-300IIL, which turns 360 mm (14.2 in) by 1,135 mm (44.7 in) on a 22 / 18.5 kW spindle at 3,500 rpm, the SC-450L trades speed for diameter, length and power. A chuck of 15 in and up is listed as an option, and bar capacity is 81 mm (3.2 in), or 89 mm (3.5 in) with the Ø89 mm option. Rolls, large shafts and heavy flanges are the natural fit.

Milling is modest by comparison. The driven tools are rated 5.5 / 3.7 kW at up to 3,600 rpm, and the turret has 12 stations. That handles bolt holes, keyways and flats, but heavy milling on parts this size belongs on a machine with a stronger tool spindle.

The Y-axis is listed as an option, giving +/- 60 mm (+/- 2.36 in) when fitted. It also raises the machine: height is 2,185 mm without it and 2,531 mm with it, so check ceiling and crane clearance before choosing the Y-axis build.

Strengths & Limitations

Strengths

480 mm (18.9 in) turning diameter and 1,520 mm (59.8 in) turning length
30 / 22 kW spindle with a 12 in chuck, and 15 in chucks listed as an option
81 mm (3.2 in) bar capacity, or 89 mm (3.5 in) with the Ø89 mm option
Optional Y-axis with +/- 60 mm (+/- 2.36 in) of travel
1,752 mm (69 in) between centers for long shafts

Limitations

Top spindle speed of 2,500 rpm makes small-diameter work slow
Driven tools rated 5.5 / 3.7 kW at 3,600 rpm are light for a machine of this size
12 turret stations for long multi-feature shafts
The Y-axis is optional and raises machine height from 2,185 mm to 2,531 mm

Best For

Long shafts up to 1,520 mm (59.8 in) Large-diameter chucked work up to 480 mm (18.9 in) Heavy roughing at 30 / 22 kW Large bar up to 89 mm (3.5 in) with the Ø89 mm option

Frequently Asked Questions

01 How large a part can the SC-450L turn?

Up to 480 mm (18.9 in) in diameter and 1,520 mm (59.8 in) long, with 1,752 mm (69 in) between centers. The standard chuck is 12 in, and chucks of 15 in and larger are listed as an option.

02 Is the Y-axis standard on the SC-450L?

No. The table marks the Y-axis as an option. When fitted it gives +/- 60 mm (+/- 2.36 in) of travel and raises the machine height from 2,185 mm to 2,531 mm, which matters in bays with low crane rails.

03 How does the SC-450L compare with the SC-300IIL?

The SC-300IIL turns up to 360 mm (14.2 in) in diameter and 1,135 mm (44.7 in) long, with a 22 / 18.5 kW spindle at 3,500 rpm. The SC-450L goes to 480 mm (18.9 in) and 1,520 mm (59.8 in) on a 30 / 22 kW spindle, with a lower 2,500 rpm top speed.

04 What milling capability does the SC-450L have?

Driven tools are rated 5.5 / 3.7 kW at up to 3,600 rpm on a 12-station turret, with +/- 60 mm (+/- 2.36 in) of Y when the optional Y-axis is fitted. That covers drilling, tapping, keyways and flats on large turned parts.

05 What bar capacity does the SC-450L have?

81 mm (3.2 in) as standard, and 89 mm (3.5 in) with the Ø89 mm option. On a machine this size many parts will be chucked blanks or forgings, but the larger bore helps for long bar-fed shafts.
