How much does the DN Solutions SMX 2100 LST cost?
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
The DN Solutions SMX 2100 LST is a long-bed mill-turn with two matched turning spindles and a weight of 17,100 kg (37,699 lb). It turns up to 1,540 mm (61 in) in length and 600 mm (24 in) in diameter, and each spindle is rated 5,000 rpm, 22 kW (30 hp) and 467 N·m (344 ft-lb). The chuck is 8 in.
Weight is the row that separates the LST from its neighbours. The SMX 2100 L shares the turning length and the main-spindle rating and weighs 16,200 kg (35,715 lb), so the LST carries about 6% more machine. The table does not say where that mass sits. DN Solutions' description of the series lists a 12 station servo turret next to the B-axis milling head, but it does not state which models have it, and this model's table has no turret rows. Anyone buying the LST for simultaneous work with two tool carriers should get the turret, its travels and its driven-tool rating confirmed in writing.
What the table does establish is a machine that can finish long parts from both ends. With equal spindles, either end of a 1,540 mm (61 in) shaft can be the driven end, and transferred parts keep 467 N·m (344 ft-lb) for second-side roughing. The B-axis and C-axis are controlled in 0.0001-degree steps according to the series description, and the tool magazine sits at the front with its own ATC operation panel.
Plan the installation around 5,630 × 2,770 mm (222 × 109 in) of floor, 2,777 mm (109 in) of height and the 17,100 kg (37,699 lb) load. The SMX 2600 S is the alternative when torque matters more than speed: 724 N·m (534 ft-lb) and 30 kW (40 hp) at 4,000 rpm on a 10 in chuck, at 16,200 kg (35,715 lb).

Strengths & Limitations
Strengths
- Two spindles, each 5,000 rpm, 22 kW (30 hp) and 467 N·m (344 ft-lb), on a 1,540 mm (61 in) turning length
- 600 mm (24 in) maximum turning diameter
- 0.0001-degree control of the B-axis and C-axis, listed by DN Solutions for the series
- Tool magazine at the front of the machine with an ATC operation panel for tool loading and checks
- Thermal compensation with cooling of spindle and feed axes is part of the series description
Limitations
- 17,100 kg (37,699 lb), about 6% more than the 16,200 kg (35,715 lb) SMX 2100 L, raises the demand on floor and rigging
- The table has no turret rows, so the tool-carrier configuration has to be confirmed with DN Solutions
- 8 in chuck and 22 kW (30 hp) per spindle; the SMX 2600 S has a 10 in chuck and 30 kW (40 hp)
- 5,630 mm (222 in) of machine length before loading space for long stock

Frequently Asked Questions
01
An 8 in chuck, 600 mm (24 in) maximum turning diameter, 1,540 mm (61 in) maximum turning length, and two spindles each rated 5,000 rpm, 22 kW (30 hp) and 467 N·m (344 ft-lb). The machine measures 5,630 × 2,770 × 2,777 mm (222 × 109 × 109 in) and weighs 17,100 kg (37,699 lb).
02
The spec table for this model has no turret row. DN Solutions' description of the SMX 2100 series lists a 12 station servo turret without stating which models carry it. Ask for the turret configuration, its travels and its tooling in writing before relying on it for a process plan.
03
The SMX 2100 LST weighs 17,100 kg (37,699 lb). The SMX 2100 L, with the same turning length, weighs 16,200 kg (35,715 lb), and the short-bed SMX 2100 weighs 14,900 kg (32,849 lb).
04
Both the main spindle and the second spindle are listed at 5,000 rpm, with 22 kW (30 hp) and 467 N·m (344 ft-lb) each. The table gives no speed for the milling spindle on this model, so request it together with the tool magazine capacity.
