Overview

The DN Solutions SMX 2600 is a 10 in chuck mill-turn with a 30 kW (40 hp) main spindle that delivers 724 N·m (534 ft-lb) and runs to 4,000 rpm. It turns up to 660 mm (26 in) in diameter and 1,540 mm (61 in) in length.

Those figures put it in the middle of its family. The SMX 3100 has the same power and the same turning envelope but a 12 in chuck, 1,203 N·m (887 ft-lb) and a 3,000 rpm limit, about 66% more torque than the SMX 2600. So the SMX 2600 is the version for work that still needs spindle speed, such as medium-diameter steel and alloy parts, and the larger model is the one for big diameters roughed slowly.

A 660 mm (26 in) turning diameter with 1,540 mm (61 in) of length suits shafts, large flanged parts and housings that need milling on several faces. DN Solutions describes the series as orthogonal in layout, with the B-axis and C-axis controlled in 0.0001-degree steps and a 12 station servo turret. It also lists cooling of the spindle and feed axes with thermal compensation, aimed at holding size through long runs. None of that is quantified in this model's table, which has no rows for the milling spindle, the tool magazine or the axis travels.

Among the models with this chuck size, the SMX 2600 S is listed at 16,200 kg (35,715 lb) and the SMX 2600 ST at 18,000 kg (39,683 lb) with 690 N·m (509 ft-lb); this model weighs 15,800 kg (34,833 lb). For longer parts the SMX 3100 L turns 2,540 mm (100 in) and weighs 20,100 kg (44,313 lb).

Length, width and height are 5,700 × 3,011 × 2,761 mm (224 × 119 × 109 in).

Strengths & Limitations

Strengths

30 kW (40 hp) and 724 N·m (534 ft-lb) at the main spindle
4,000 rpm top speed, against 3,000 rpm on the 12 in SMX 3100
Turning envelope of 660 mm (26 in) by 1,540 mm (61 in)
At 15,800 kg (34,833 lb) it weighs less than the SMX 2600 S and the SMX 2600 ST
Series description lists thermal compensation with cooling of the spindle and feed axes

Limitations

The SMX 3100 gives 1,203 N·m (887 ft-lb) with the same 30 kW (40 hp), so the SMX 2600 is not the pick for the heaviest low-speed roughing
No second-spindle rows in this model's table; the back of the part needs another setup
Turning length stops at 1,540 mm (61 in), where the SMX 3100 L reaches 2,540 mm (100 in)
Needs 5,700 × 3,011 mm (224 × 119 in) of floor
Milling-spindle, tool-magazine and axis-travel figures are not in the table

Best For

Shafts and housings up to 1,540 mm (61 in) long with milled features Medium-diameter steel parts that need both 724 N·m (534 ft-lb) and 4,000 rpm Large flanged parts up to 660 mm (26 in) in turning diameter One-sided parts or work finished in a single chucking

Frequently Asked Questions

01 What is the turning capacity of the SMX 2600?

Maximum turning diameter is 660 mm (26 in) and maximum turning length is 1,540 mm (61 in), with a 10 in chuck. The SMX 3100 has the same envelope with a 12 in chuck, and the SMX 3100 L extends turning length to 2,540 mm (100 in).

02 How powerful is the SMX 2600 spindle?

The main spindle is rated 30 kW (40 hp) and 724 N·m (534 ft-lb), with a maximum speed of 4,000 rpm. The table gives a single power figure and no speed at which the torque is reached, so ask for the power and torque diagram if low-speed roughing is the main job.

03 Should I choose the SMX 2600 or the SMX 3100?

It depends on diameter and speed. The SMX 3100 has a 12 in chuck and 1,203 N·m (887 ft-lb) at up to 3,000 rpm, and weighs 16,300 kg (35,935 lb). The SMX 2600 has a 10 in chuck and 724 N·m (534 ft-lb) at up to 4,000 rpm, and weighs 15,800 kg (34,833 lb). Power is 30 kW (40 hp) on both.

04 How do the SMX 2600 S and SMX 2600 ST differ from the SMX 2600?

In the figures available here, by weight and main-spindle torque. The SMX 2600 S lists the same 724 N·m (534 ft-lb) and weighs 16,200 kg (35,715 lb). The SMX 2600 ST lists 690 N·m (509 ft-lb) and weighs 18,000 kg (39,683 lb). The SMX 2600 weighs 15,800 kg (34,833 lb).

05 What space does the SMX 2600 need?

The machine is 5,700 mm (224 in) long, 3,011 mm (119 in) wide and 2,761 mm (109 in) high, and it weighs 15,800 kg (34,833 lb). Confirm floor capacity and the access route for a machine of that size before ordering.
