Our best estimate for a vertical machining centers (vmc) in this class — not a quote from DN Solutions. Configuration moves it a long way.

Overview

The DN Solutions DNM 650 50 II is a 50-taper machine in the DNM vertical machining center line: an ISO 50 spindle with 353.2 N·m (261 ft-lb) of torque and a top speed of 8,000 rpm, over travels of 1,270 × 670 × 625 mm (50 × 26 × 25 in). It weighs 9,000 kg (19,842 lb).

Torque is the reason to buy it. The ISO 40 machines around it, the DNM 6700 4TH among them, list 117.8 N-m (87 ft-lb), one third of the figure here. With the larger taper comes a stiffer tool connection, so large face mills, long boring bars, big indexable drills and heavy taps run with less risk of chatter or pull-out. Steel, cast iron and tough alloys are the natural materials for it. The power row of DN's table reads 22 with no unit printed, so have the spindle rating confirmed with the quotation.

The envelope is close to that of the DNM 6700 4TH, which has 1,300 mm (51 in) of X and the same Y and Z. Rapids are also the same at 36 m/min (1,417 ipm) on X and Y and 30 m/min (1,181 ipm) on Z. The differences are in the table. Here it measures 1,300 × 670 mm (51 × 26 in) and carries 1,000 kg (2,205 lb), while the DNM 6700 4TH has a 1,500 × 670 mm (59 × 26 in) table rated for 1,300 kg (2,866 lb). A buyer with heavy workpieces should check the weight of part plus fixture against that 1,000 kg before assuming the 50-taper machine is the heavier-duty one in every respect.

DN describes the spindle as direct-coupled, and grease lubrication for the axis roller guideways is standard. Installation needs 2,740 × 3,350 mm (108 × 132 in) of floor and 3,250 mm (128 in) of height. Large holders are heavy and long, so ask DN for the magazine capacity and the tool size and weight limits, none of which appear in the table.

Strengths & Limitations

Strengths

353.2 N·m (261 ft-lb) of spindle torque, three times the 117.8 N-m (87 ft-lb) of the DNM 6700 4TH
ISO 50 taper for large face mills, boring bars and drills
670 mm (26 in) of Y and 625 mm (25 in) of Z for deep and tall workpieces
Direct-coupled spindle that still reaches 8,000 rpm
9,000 kg (19,842 lb) of machine weight behind an envelope of 1,270 × 670 × 625 mm (50 × 26 × 25 in)

Limitations

Table load is 1,000 kg (2,205 lb), below the 1,300 kg (2,866 lb) of the DNM 6700 4TH
X travel of 1,270 mm (50 in) is shorter than the 1,500 mm (59 in) of the DNM 6700 L
DN's table states the spindle power as 22 without a unit
Rapids of 36 m/min (1,417 ipm) on X and Y trail the 42 m/min (1,654 ipm) of the DNM 5700 L 4TH
Tool capacity and maximum tool size are not listed, and a shop tooled for ISO 40 needs a separate set of ISO 50 holders

Best For

Heavy roughing in steel and cast iron with large face mills Boring and large-diameter drilling that needs 353.2 N·m (261 ft-lb) Die blocks and machine components within 1,000 kg (2,205 lb) Shops already tooled with ISO 50 holders

Frequently Asked Questions

01 How much torque does the DNM 650 50 II have?

DN lists 353.2 N·m (261 ft-lb) on an ISO 50 spindle that runs to 8,000 rpm. The table does not give the speed range over which that torque is available, and it shows the power as 22 with no unit, so request the spindle diagram when comparing it with other machines.

02 How does the DNM 650 50 II compare with the DNM 6700 4TH?

Y, Z and rapids are the same. The DNM 6700 4TH has an ISO 40 spindle with 18.5 kW (25 hp) and 117.8 N-m (87 ft-lb), 1,300 mm (51 in) of X, a 1,500 × 670 mm (59 × 26 in) table for 1,300 kg (2,866 lb) and weighs 8,500 kg (18,739 lb). The DNM 650 50 II has the ISO 50 spindle, 1,270 mm (50 in) of X, a 1,300 × 670 mm (51 × 26 in) table for 1,000 kg (2,205 lb) and weighs 9,000 kg (19,842 lb).

03 What size workpiece does it take?

Travels are 1,270 mm (50 in) in X, 670 mm (26 in) in Y and 625 mm (25 in) in Z. The table is 1,300 × 670 mm (51 × 26 in) with a 1,000 kg (2,205 lb) load limit that includes fixtures. X travel is slightly shorter than the table, so the full table length cannot be machined.

04 Is 8,000 rpm enough on a 50-taper machine?

For the work an ISO 50 spindle is bought for, yes: large cutters run at low speeds and need the 353.2 N·m (261 ft-lb). At 8,000 rpm the machine can also finish with medium end mills. Very small cutters in aluminium are better served by a faster spindle.

05 What are the installation dimensions?

DN lists 2,740 × 3,350 × 3,250 mm (108 × 132 × 128 in) as length, width and height and 9,000 kg (19,842 lb) for the machine. The 3,250 mm (128 in) height is the one to check against the building.
