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 DNX 2100 is a multitasking turning center with a 210 mm (8 in) chuck and a 5,000 rpm main spindle, for work up to 520 mm (21 in) in diameter and 1,100 mm (43 in) long. The main spindle is a built-in unit listed at 18.5/15 kW (25/20 hp) and 326 N·m (240 ft-lb).

Within the DNX 2100 family the chuck size decides the spindle. The DNX 2100 B has a 255 mm (10 in) chuck, 4,000 rpm, 22/15 kW (30/20 hp) and 456 N·m (336 ft-lb) over the same 520 mm by 1,100 mm capacity. The DNX 2100 therefore has 25% more top speed and the DNX 2100 B about 40% more torque. Shaft-type parts, bar-fed components and anything turned at small diameters favour the 5,000 rpm spindle. Large-diameter roughing in tough material favours the B.

DN Solutions describes the DNX series as having first and second spindles, a milling spindle on a B-axis controlled in 0.0001° increments, and a servo tailstock, laid out on an orthogonal structure. The table for this model does not say whether it carries the second spindle or the tailstock. The DNX 2100 S has identical chuck, capacity and spindle rows, so settle the configuration by name with DN Solutions before comparing quotations.

Standard items named for the series are a 7 inch ATC magazine screen, DSSV spindle speed variation, an alarm recovery function and a chuck position sensor, along with machining cycles such as Eccentric Turning. Under options DN lists a tool breakage detection device inside the magazine, an arm-type tool setter and a servo parts catcher with a settable unloading position.

The footprint is 4,615 × 2,285 mm (182 × 90 in) with a height of 2,630 mm (104 in). The table for the DNX 2100 gives no machine weight. The DNX 2100 S is listed at 10,850 kg (23,920 lb) and the DNX 2100 B at 10,650 kg (23,479 lb), which indicates the class. Axis travels, milling spindle ratings and tool magazine capacity are also absent from the table and need to come from DN Solutions.

Strengths & Limitations

Strengths

5,000 rpm main spindle, 25% faster than the 4,000 rpm of the DNX 2100 B
Capacity of 520 mm (21 in) in turning diameter and 1,100 mm (43 in) in turning length
The B-axis of the milling spindle is controlled in 0.0001° increments, as DN Solutions states for the series
Built-in main spindle is standard, listed at 18.5/15 kW (25/20 hp) and 326 N·m (240 ft-lb)
DSSV spindle speed variation and a 7 inch ATC magazine screen are standard features of the series

Limitations

326 N·m (240 ft-lb) of main spindle torque, against 456 N·m (336 ft-lb) on the DNX 2100 B
The chuck is 210 mm (8 in); the DNX 2100 B takes a 255 mm (10 in) chuck
Tool breakage detection, the arm-type tool setter and the parts catcher are listed under options
The table gives no machine weight, axis travels, milling spindle rating or tool capacity for this model

Best For

Shafts and long parts up to 1,100 mm (43 in) turned and milled in one setup Small and medium diameters where 5,000 rpm keeps the cutting speed up Parts with angled holes and faces that use the 0.0001° B-axis Eccentric parts, using the Eccentric Turning cycle DN Solutions lists Finish turning helped by DSSV spindle speed variation

Frequently Asked Questions

01 What is the difference between the DNX 2100 and the DNX 2100 B?

Chuck and main spindle. The DNX 2100 has a 210 mm (8 in) chuck with 5,000 rpm, 18.5/15 kW (25/20 hp) and 326 N·m (240 ft-lb). The DNX 2100 B has a 255 mm (10 in) chuck with 4,000 rpm, 22/15 kW (30/20 hp) and 456 N·m (336 ft-lb). Maximum turning diameter and length are the same on both, 520 mm (21 in) and 1,100 mm (43 in).

02 Does the DNX 2100 have a second spindle?

The table for this model does not say. DN Solutions describes the DNX series as offering first and second spindles and a servo tailstock, and the DNX 2100 S is listed with the same chuck, capacity and main spindle figures as the DNX 2100. Confirm with DN Solutions which of the two a given configuration includes.

03 Which features are standard on the DNX 2100 and which are options?

DN Solutions names the built-in spindle, the 7 inch ATC magazine screen and DSSV (DN Solutions Spindle Speed Variation) as standard for the series, and also lists an alarm recovery function and a chuck position sensor. Listed under options are a tool breakage detection device integrated in the magazine, an arm-type tool setter and the parts catcher.

04 How does the DNX 2100 compare with the SMX 2100?

The SMX 2100 is listed with an 8 in chuck, 600 mm (24 in) of turning diameter, 1,040 mm (41 in) of turning length, 5,000 rpm, 22 kW (29 hp) and 467 N·m (344 ft-lb), and it weighs 14,900 kg (32,849 lb). The DNX 2100 has the same top speed with 326 N·m (240 ft-lb), a 520 mm (21 in) turning diameter and a longer 1,100 mm (43 in) turning length.

05 How much floor space does the DNX 2100 need?

The listed dimensions are 4,615 × 2,285 × 2,630 mm (182 × 90 × 104 in), given as length, width and height. The table does not include a machine weight for this model or the space taken by a bar feeder or chip conveyor, so ask for the layout drawing.
