Overview

The DN Solutions BM 2740 M is the flagship of DN Solutions' fixed-crossrail bridge-type VMC lineup, built for mold shops that machine the largest automotive and industrial tooling. With 4,000 x 2,700 x 800 mm of travel and a 4,000 x 2,500 mm table rated for 15,000 kg, this machine handles full-size car bumper molds, large appliance molds, and oversize progressive dies that demand absolute stability during machining.

The spindle runs ISO 50 taper at 12,000 RPM with 30 kW and 420 Nm of torque — the same proven unit found across the BM series. Bridge construction means the 15-ton mold block stays put on the table while the spindle does all the moving, eliminating the accuracy-robbing momentum effects you get when a heavy table accelerates and decelerates on a C-frame machine. For parts this heavy, that design difference isn't optional — it's mandatory for the surface quality mold makers demand.

Linear scales on all axes and thermal displacement compensation come standard. At 48,000 kg, the BM 2740 M has the mass to damp vibrations during heavy roughing, and the dual-contact spindle keeps things smooth during finishing. X-axis rapids hit 12 m/min (slightly slower than the smaller BMs due to the longer travel distance), with Y and Z at 16 m/min. The machine footprint stretches to 5,535 x 10,825 mm — you'll need a dedicated bay with a solid foundation. For shops producing the biggest molds in the business, this machine keeps you competitive against the European gantry mill brands at a more accessible price point.

Strengths & Limitations

Strengths

15,000 kg table capacity handles the largest automotive and industrial molds without compromising accuracy
4,000 mm X and 2,700 mm Y travel covers full-size car bumper molds and oversize progressive dies
Bridge design eliminates table-momentum errors that plague C-frame machines on heavy workpieces
48,000 kg machine mass provides exceptional vibration damping during heavy roughing cuts
Linear scales and thermal compensation maintain micron-level accuracy through long machining cycles
Competitively priced against European gantry mills with similar capability

Limitations

48,000 kg weight and 10.8-meter width demand significant foundation engineering and floor space
800 mm Z-travel limits deep-cavity capability — consider DCM-series W-axis models for deeper work
12 m/min X-axis rapids are slower than smaller bridge mills, adding to non-cutting time on long traverses
High acquisition cost puts this machine beyond the reach of smaller mold shops

Best For

Large automotive mold shops producing bumper molds, instrument panel molds, and door panel tooling Tier 1 mold makers needing bridge-mill rigidity for the heaviest mold blocks in production Die shops machining oversize progressive and transfer dies for heavy-gauge automotive stampings Shops replacing aging gantry mills who want modern CNC capability at a lower price point Aerospace tooling manufacturers producing large composite molds and forming tools

Frequently Asked Questions

01 What does the DN Solutions BM 2740 M cost?

New BM 2740 M bridge-type VMCs typically run $600,000-$850,000 depending on spindle options, control package, and accessories. That's competitive against European bridge and gantry mills that can easily exceed $1 million for similar capability.

02 How does the BM 2740 M compare to the DCM 2740 F II?

The DCM 2740 F II is a W-axis crossrail double column machine with similar X/Y travel but adds a W-axis for additional Z-depth flexibility. The BM 2740 M is a fixed-crossrail bridge design that's simpler and typically less expensive. Choose the DCM when you need the W-axis; the BM when fixed-crossrail rigidity suffices.

03 What mold sizes can the BM 2740 M handle?

With a 4,000 x 2,500 mm table and 15,000 kg capacity, it handles mold blocks up to roughly 3,800 x 2,300 mm. That covers the vast majority of automotive exterior molds, large appliance molds, and industrial tooling.

04 Is a 5-axis version available?

Yes, DN Solutions offers the BM 2740 U variant with a universal head for 5-axis machining capability. The U version is categorized under 5-axis machining centers and adds continuous A/C head rotation for complex mold surface contouring.
