Our best estimate for a mill-turn / multi-tasking machine in this class — not a quote from DN Solutions. Configuration moves it a long way.

Overview

A 10 in chuck, 512 N·m (378 ft-lb) of spindle torque and a 4,000 rpm ceiling define the DN Solutions SMX 2100 B, the larger-chuck version of the short-bed SMX 2100 mill-turn. Turning capacity is 600 mm (24 in) in diameter and 1,040 mm (41 in) in length, and spindle power is 22 kW (29 hp).

Power is identical on the two models, so the B's spindle trades speed for torque. The SMX 2100 lists 467 N·m (344 ft-lb) and 5,000 rpm with its 8 in chuck; the B has about 10% more torque and a top speed of 4,000 rpm. The gain is grip and pull on larger blanks. The cost is surface speed on small diameters, where a brass or aluminium part may want more revolutions than this spindle has.

Little else in the table moves. Length, width and height are 4,845 × 2,770 × 2,777 mm (191 × 109 × 109 in), and the B weighs 15,000 kg (33,069 lb) against 14,900 kg (32,849 lb) for the SMX 2100, so one foundation and rigging plan covers either.

If the reason for wanting a 10 in chuck is heavier cutting and not just a larger grip diameter, compare the next size up too. The SMX 2600 has the same chuck size and 4,000 rpm, with 30 kW (40 hp), 724 N·m (534 ft-lb), 660 mm (26 in) of turning diameter and 1,540 mm (61 in) of turning length.

The milling side is described only at series level: B-axis and C-axis positioning to 0.0001 degree, a 12 station servo turret and a tool magazine loaded from the front. The B's own table has no milling-spindle, magazine or travel figures.

Strengths & Limitations

Strengths

512 N·m (378 ft-lb) of spindle torque, about 10% more than the 467 N·m (344 ft-lb) of the SMX 2100
10 in chuck for larger blanks within the 600 mm (24 in) turning diameter
Floor area of 4,845 × 2,770 mm (191 × 109 in) with 2,777 mm (109 in) of height
Weighs 15,000 kg (33,069 lb), close to the 14,900 kg (32,849 lb) of the SMX 2100, so installation planning barely changes
B-axis and C-axis positioning in 0.0001-degree steps is part of the series description

Limitations

Top speed is 4,000 rpm, down from 5,000 rpm on the SMX 2100, which costs surface speed on small diameters
Power stays at 22 kW (29 hp); the SMX 2600 offers 30 kW (40 hp) and 724 N·m (534 ft-lb) with the same chuck size
Turning length is 1,040 mm (41 in), against 1,540 mm (61 in) on the SMX 2600
The table gives no figures for the milling spindle, tool magazine or axis travels

Best For

Blanks that need a 10 in chuck but fit within 1,040 mm (41 in) of turning length Steel roughing at low and medium speeds using 512 N·m (378 ft-lb) Disc and flange parts up to 600 mm (24 in) in diameter with milled features Work that rarely needs more than 4,000 rpm at the turning spindle

Frequently Asked Questions

01 What does the B change on the SMX 2100 B?

Three rows of the table. Chuck size goes from 8 in on the SMX 2100 to 10 in, maximum spindle speed from 5,000 rpm to 4,000 rpm, and spindle torque from 467 N·m (344 ft-lb) to 512 N·m (378 ft-lb). Power, turning diameter and turning length are unchanged.

02 Does the larger chuck come with more spindle power?

No. The SMX 2100 B is rated 22 kW (29 hp), the same as the SMX 2100. Torque is higher at 512 N·m (378 ft-lb) and top speed is lower at 4,000 rpm. For more power with a 10 in chuck, the SMX 2600 lists 30 kW (40 hp) and 724 N·m (534 ft-lb).

03 How long a part can the SMX 2100 B turn?

Maximum turning length is 1,040 mm (41 in) and maximum turning diameter is 600 mm (24 in). The SMX 2100 L and the SMX 2600 both reach 1,540 mm of turning length, the first with an 8 in chuck and the second with a 10 in chuck.

04 Is the SMX 2100 B bigger or heavier than the SMX 2100?

Barely. The SMX 2100 B weighs 15,000 kg (33,069 lb) and the SMX 2100 weighs 14,900 kg (32,849 lb). The B measures 4,845 × 2,770 × 2,777 mm (191 × 109 × 109 in) as length, width and height.
