Estimated price range
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
On the DN Solutions SMX 2100 SB the main spindle and the second spindle are not the same. The main spindle carries a 10 in chuck and is rated 4,000 rpm and 512 N·m (378 ft-lb); the second spindle is rated 5,000 rpm and 467 N·m (344 ft-lb). Each has 22 kW (29 hp). Turning capacity is 600 mm (24 in) in diameter and 1,040 mm (41 in) in length.
With equal power at both ends, the difference is one of speed range: the main spindle has about 10% more torque and the second spindle turns 25% faster. That fits the way two-operation parts are usually run. The raw blank, at its largest and heaviest, goes in the 10 in chuck for roughing. After transfer the part is lighter and partly finished, and the faster spindle suits the smaller diameters and finishing cuts that remain. The second spindle still has 467 N·m (344 ft-lb), so real roughing can be left for the back side when the part demands it.
The SMX 2100 B lists the same main spindle and chuck at 15,000 kg (33,069 lb); the SB weighs 15,300 kg (33,731 lb). Its dimensions are 4,845 mm (191 in) in length, 2,770 mm (109 in) in width and 2,777 mm (109 in) in height.
Buyers drawn to the 10 in chuck for heavy work should also read the SMX 2600 S figures: 30 kW (40 hp) and 724 N·m (534 ft-lb) at 4,000 rpm, with 660 mm (26 in) of turning diameter and 1,540 mm (61 in) of turning length. The SMX 2100 SB is the choice when 1,040 mm (41 in) is enough and a 5,000 rpm second spindle is useful.
On the milling side, DN Solutions describes the series with a front-located tool magazine and a 12 station servo turret. Neither appears as figures in the SB's table.

Strengths & Limitations
Strengths
- Main spindle with a 10 in chuck and 512 N·m (378 ft-lb) for roughing the raw blank
- Second spindle runs to 5,000 rpm, 25% faster than the 4,000 rpm main spindle, for smaller finished diameters
- Both spindles are rated 22 kW (29 hp), and the second still delivers 467 N·m (344 ft-lb)
- 600 mm (24 in) turning diameter and 1,040 mm (41 in) turning length on the short-bed frame
- Front-located tool magazine, listed for the series, keeps tool loading at the operator side
Limitations
- First-side turning is capped at 4,000 rpm, a limit on small-diameter work held in the main chuck
- Turning length of 1,040 mm (41 in); the SMX 2600 S offers 1,540 mm (61 in)
- The table shows 22 kW (29 hp) per spindle, below the 30 kW (40 hp) of the SMX 2600 S
- The 12 station servo turret is a series statement; the SB's table has no turret, milling-spindle or magazine rows

Frequently Asked Questions
01
The main spindle has a 10 in chuck and is rated 4,000 rpm, 22 kW (29 hp) and 512 N·m (378 ft-lb). The second spindle is rated 5,000 rpm, 22 kW (29 hp) and 467 N·m (344 ft-lb). Power is equal; the main spindle has about 10% more torque and the second spindle 25% more speed.
02
For work on the back of the part. The SMX 2100 B lists the same 10 in chuck, 4,000 rpm and 512 N·m (378 ft-lb) and weighs 15,000 kg (33,069 lb). The SMX 2100 SB adds second-spindle rows, 5,000 rpm and 467 N·m (344 ft-lb), and weighs 15,300 kg (33,731 lb).
03
Maximum turning diameter is 600 mm (24 in) and maximum turning length is 1,040 mm (41 in). The main chuck is 10 in. The table does not give a chuck size for the second spindle, so confirm it if the back-side grip diameter is critical.
04
No. The SMX 2100 and the SMX 2100 SB are both rated 22 kW (29 hp) at the main spindle. The SMX 2100 has 467 N·m (344 ft-lb) at up to 5,000 rpm with an 8 in chuck; the SB has 512 N·m (378 ft-lb) at up to 4,000 rpm.
