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 B is the 10 in chuck version of the DNX 2100 multitasking turning center: a 255 mm (10 in) chuck on a main spindle listed at 4,000 rpm, 22/15 kW (30/20 hp) and 456 N·m (336 ft-lb). Maximum turning diameter is 520 mm (21 in), maximum turning length is 1,100 mm (43 in) and the machine weighs 10,650 kg (23,479 lb).

What the larger chuck brings with it is torque. Against the DNX 2100, with its 210 mm (8 in) chuck, 5,000 rpm and 326 N·m (240 ft-lb), the B gains about 40% in torque while top speed falls by a fifth. That is the right trade for work near the 520 mm limit. At large diameters the cutting speed is reached at a few hundred rpm, and torque is what decides the depth of cut in alloy steel, stainless or forgings.

The work envelope does not change with the chuck: the DNX 2100 lists the same 520 mm by 1,100 mm capacity. The choice between them rests on the part. Flanges, hubs, discs and thick-walled sleeves belong on the B. Slender shafts and small-diameter bar work run better on the faster spindle.

The DNX 2100 SB carries the same chuck, speed, power and torque figures at a listed weight of 11,000 kg (24,251 lb). DN Solutions describes the series with first and second spindles, a milling spindle on a 0.0001° B-axis and a servo tailstock, but the table for the DNX 2100 B does not state which of the second spindle and tailstock it has, so confirm that when ordering.

The footprint is 4,615 × 2,285 mm (182 × 90 in) and the height 2,630 mm (104 in). For the series DN lists a built-in main spindle, a chuck position sensor, an alarm recovery function, DSSV spindle speed variation and a 7 inch ATC magazine screen as standard. Tool breakage detection in the magazine, an arm-type tool setter and a parts catcher appear under options.

Strengths & Limitations

Strengths

456 N·m (336 ft-lb) of main spindle torque, about 40% more than the 326 N·m (240 ft-lb) of the DNX 2100
255 mm (10 in) chuck for larger and heavier workpieces
22/15 kW (30/20 hp) main spindle rating, against 18.5/15 kW (25/20 hp) on the DNX 2100
Turning capacity of 520 mm (21 in) by 1,100 mm (43 in) with a B-axis milling spindle indexed in 0.0001° increments
A chuck position sensor, which DN Solutions says reduces process and chuck replacement time, is listed for the series

Limitations

Top speed is 4,000 rpm, where the DNX 2100 reaches 5,000 rpm, which slows small-diameter turning
The table lists no axis travels, milling spindle speed or power, or tool magazine capacity
The parts catcher, arm-type tool setter and tool breakage detection are listed under options
At 10,650 kg (23,479 lb) the floor and rigging plan need checking for a machine 4,615 mm (182 in) long

Best For

Flanges, hubs and discs gripped in a 255 mm (10 in) chuck Roughing large diameters in steel with 456 N·m (336 ft-lb) Complete machining of parts up to 520 mm (21 in) in diameter with milled features Long workpieces up to 1,100 mm (43 in) that need heavy turning cuts

Frequently Asked Questions

01 Why choose the DNX 2100 B instead of the DNX 2100?

For chuck size and torque. The DNX 2100 B has a 255 mm (10 in) chuck and 456 N·m (336 ft-lb) at up to 4,000 rpm, with a 22/15 kW (30/20 hp) rating. The DNX 2100 has a 210 mm (8 in) chuck and 326 N·m (240 ft-lb) at up to 5,000 rpm, with 18.5/15 kW (25/20 hp). Turning diameter and length are identical, so the B suits heavier cuts on larger diameters.

02 What is the spindle power of the DNX 2100 B?

The main spindle is listed at 22/15 kW (30/20 hp), a pair of ratings as DN Solutions prints them, with 456 N·m (336 ft-lb) of torque and a top speed of 4,000 rpm. The table gives no figures for the milling spindle, so its speed and power need to be requested.

03 How does the DNX 2100 B differ from the DNX 2100 SB?

In the table the two share a 255 mm (10 in) chuck, 4,000 rpm, 22/15 kW (30/20 hp), 456 N·m (336 ft-lb) and the same 520 mm (21 in) by 1,100 mm (43 in) capacity. The listed weights differ: 10,650 kg (23,479 lb) for the DNX 2100 B and 11,000 kg (24,251 lb) for the DNX 2100 SB. The table does not name the equipment behind that difference.

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

The SMX 2100 B is listed with a 10 in chuck, 600 mm (24 in) of turning diameter, 1,040 mm (41 in) of turning length, 4,000 rpm, 22 kW (29 hp) and 512 N·m (378 ft-lb), at 15,000 kg (33,069 lb). The DNX 2100 B has the same top speed with 456 N·m (336 ft-lb), turns 520 mm (21 in) by 1,100 mm (43 in) and weighs 10,650 kg (23,479 lb).

05 What are the dimensions and weight of the DNX 2100 B?

DN Solutions lists 4,615 × 2,285 × 2,630 mm (182 × 90 × 104 in) as length, width and height, and a machine weight of 10,650 kg (23,479 lb). Bar feeders, chip conveyors and the optional parts catcher are not included in those figures.
