Our best estimate for a 5-axis machining center in this class — not a quote from DN Solutions. Configuration moves it a long way.

Overview

On the DN Solutions BM 2740 U the table and the travels are the same size: 4,000 mm (157 in) of X and 2,500 mm (98 in) of Y over a 4,000 × 2,500 mm (157 × 98 in) table. Z travel is 800 mm (31 in). It is a bridge-type five-axis machine with a universal head and a 15,000 rpm spindle listed at 45.9 kW (62 hp) and 146.1 N·m (108 ft-lb), and the table is rated for 15,000 kg (33,069 lb).

That one-to-one match matters for five-axis work. The spindle centreline reaches every point on the table top, but it cannot travel beyond the table edge in Y, so a part that fills the full width leaves no room for the head to tilt down its long sides. Wide workpieces are best planned for top and angled-face machining, with side walls kept for parts narrower than the table. The BM 2035 U takes the opposite approach, with 2,050 mm (81 in) of Y over a 1,600 mm (63 in) wide table and a 10,000 kg (22,046 lb) load limit.

Within the BM 2740 family the U is the high-speed choice. The BM 2740 lists a 10,000 rpm ISO 50 spindle with 30 kW (40 hp) and 420 N·m (310 ft-lb), and the BM 2740 M a 12,000 rpm version of the same rating. The BM 2740 and the BM 2740 M each have 2,700 mm (106 in) of Y where the U has 2,500 mm (98 in). X rapid is 12 m/min (472 ipm), Y is 16 m/min (630 ipm) and Z is 12 m/min (472 ipm). The BM 2740 is quicker on every axis at 16, 24 and 24 m/min, so the U is a contouring machine first and a positioning machine second.

For the series, DN lists linear scales on all axes, cooled ball screw bearings and nuts, a dual contact spindle and thermal displacement compensation for spindle and structure, all as standard. The machine weighs 48,700 kg (107,365 lb) and occupies 6,011 × 10,984 × 4,995.5 mm (237 × 432 × 197 in).

Strengths & Limitations

Strengths

4,000 × 2,500 mm (157 × 98 in) table with matching X and Y travel, so the whole table top is within reach of the spindle
15,000 kg (33,069 lb) table load, against 10,000 kg (22,046 lb) on the BM 2035 U and on the BM 2740
15,000 rpm spindle with 45.9 kW (62 hp), where the BM 2740 M stops at 12,000 rpm and 30 kW (40 hp)
Thermal displacement compensation for spindle and structure and linear scales on all axes are standard for the series
DN describes the spindle nose as a long-nose type suited to deep pocket mold machining

Limitations

Y travel equals the 2,500 mm (98 in) table width, so the head cannot pass the table edge to machine the long sides of a full-width part
X and Z rapids are 12 m/min (472 ipm); the BM 2740 moves at 16 m/min (630 ipm) in X and 24 m/min (945 ipm) in Z
146.1 N·m (108 ft-lb) of spindle torque, compared with 420 N·m (310 ft-lb) on the BM 2740 M
The table for this model has no spindle taper row and no tool magazine figure; the taper appears only in the series description, as HSK A-100 for the 15,000 r/min spindle

Best For

Large mold and die blocks up to 15,000 kg (33,069 lb) Wide plates and panels machined on the top and angled faces across a 2,500 mm (98 in) table Finishing and semi-finishing at 15,000 rpm where surface quality matters more than metal removal rate Several smaller parts set side by side on a 4,000 mm (157 in) long table

Frequently Asked Questions

01 How big a part fits on the BM 2740 U?

The table is 4,000 × 2,500 mm (157 × 98 in) and carries 15,000 kg (33,069 lb). X travel is 4,000 mm (157 in), Y is 2,500 mm (98 in) and Z is 800 mm (31 in). Since Y travel is no greater than the table width, plan side-wall machining only for parts that leave space beside them.

02 What is the difference between the BM 2740 U and the BM 2740 M?

The BM 2740 M has a 12,000 rpm ISO 50 spindle with 30 kW (40 hp) and 420 N·m (310 ft-lb), 2,700 mm (106 in) of Y and a 16 m/min (630 ipm) Z rapid. The BM 2740 U has a universal head with a 15,000 rpm spindle at 45.9 kW (62 hp) and 146.1 N·m (108 ft-lb), 2,500 mm (98 in) of Y and a 12 m/min (472 ipm) Z rapid. Table size and the 15,000 kg (33,069 lb) load are the same.

03 Is the BM 2740 U a fast machine?

The spindle is fast, the axes are not. Rapids are 12 m/min (472 ipm) in X and Z and 16 m/min (630 ipm) in Y. The BM 2740 in the same family lists 16 m/min (630 ipm) in X and 24 m/min (945 ipm) in Y and Z. On long contouring programs the feed rate governs the cycle, so the lower rapids matter mainly on jobs with many repositioning moves.

04 What does DN include as standard on the BM U series?

The series description lists a dual contact spindle, linear scales on all axes, a cooling system for the ball screw bearings and nuts, covers that reduce the influence of ambient temperature, and thermal displacement compensation for the spindle and structure.

05 How much floor space and foundation does the BM 2740 U need?

DN lists 6,011 × 10,984 × 4,995.5 mm (237 × 432 × 197 in) for the machine and a weight of 48,700 kg (107,365 lb). Add the 15,000 kg (33,069 lb) the table can carry when sizing the foundation, and check crane access over the table for loading.
