Overview

The DN Solutions DNM 750 II is a large-format 40-taper VMC with 1,630 x 762 x 650 mm (64 x 30 x 26 in) of axis travel — the same envelope as the 50-taper DNM 750 50 II but with the speed and tooling economy of an ISO 40 platform. For shops that need the big work area but don't require 50-taper torque levels, the DNM 750 II hits a compelling price-to-performance sweet spot.

The spindle runs 8,000 RPM with 118 Nm of torque through an ISO 40 taper. That's solid general-purpose power for steel and aluminum at moderate feed rates. The box-way construction provides the rigidity foundation that makes this large-envelope machine viable for production work — without ways this well-tuned, accuracy at the far reaches of 1,630 mm X-travel would be questionable.

The table measures 1,630 x 760 mm with a generous 1,500 kg load capacity, matching the 50-taper sibling's platform. At 13,500 kg machine weight, you've got enormous thermal mass that keeps dimensions stable through temperature swings during long production runs. The second-generation design adds improved servo drives and thermal compensation that reduce warm-up time and maintain tighter tolerances.

This is the machine for shops doing mid-to-large production work in mixed materials — steel, aluminum, cast iron — where the parts are big but don't demand 50-taper torque levels. The 40-taper tooling costs less, is easier to handle, and tooling inventory is far more interchangeable with other machines in the shop. It's also a natural upgrade path for shops running smaller DNM models that are growing into bigger parts.

Strengths & Limitations

Strengths

Massive 1,630 x 762 x 650 mm work envelope in a 40-taper platform — big-part capability without 50-taper tooling costs
1,500 kg table capacity handles heavy castings and large multi-part fixtures with room to spare
13,500 kg machine weight delivers exceptional vibration damping for a 40-taper VMC
ISO 40 tooling is lighter, cheaper, and more interchangeable with the rest of your shop's tool inventory
Box-way construction maintains accuracy across the full 1,630 mm X-travel range
Second-generation servo drives and thermal compensation improve cold-start accuracy and long-run stability

Limitations

118 Nm spindle torque is modest for this size machine — heavy steel roughing hits the torque limit faster than a 50-taper
8,000 RPM max speed isn't enough for high-speed aluminum finishing with small tools
13,500 kg weight requires substantial foundation preparation and limits relocation options
Large footprint may be hard to justify for shops that rarely see parts needing 64 inches of X-travel

Best For

Shops machining mid-to-large aluminum and mild steel parts that need a big envelope without 50-taper costs Production facilities running multi-part fixture setups across the wide table surface for throughput efficiency Aerospace shops working with large aluminum structural components and subassemblies Shops upgrading from smaller DNM models that are outgrowing their X and Y travel limits Job shops needing versatile large-format capability across mixed materials on a 40-taper platform

Frequently Asked Questions

01 What does a DN Solutions DNM 750 II cost?

Expect $130,000-$180,000 new. That's roughly $20,000-$30,000 less than the 50-taper DNM 750 50 II for the same envelope. Used Doosan-era DNM 750 models sell for $50,000-$90,000 depending on hours and configuration.

02 Should I get the DNM 750 II or the 750 50 II?

If your primary work is heavy steel and cast iron roughing with large-diameter cutters, get the 50-taper for its 353 Nm torque. If you run a mix of materials including aluminum, or want cheaper, lighter tooling, the 40-taper DNM 750 II is the better choice. Same envelope, different spindle philosophy.

03 How does the DNM 750 II compare to the DNM 6700 XL?

The DNM 750 II has more Y-travel (762 vs 670 mm), more Z-travel (650 vs 625 mm), and a larger table (1,630x760 vs 2,200x670 mm). The 6700 XL has more X-travel (2,100 vs 1,630 mm). Choose the 750 II for wider and deeper parts; the 6700 XL for longer parts.

04 Is the DNM 750 II too big for a small job shop?

The 13,500 kg weight and large footprint do require dedicated floor space and foundation prep. But if your work regularly involves parts over 40 inches long or heavy fixtures, the 750 II earns its space. For shops that only occasionally see big parts, a DNM 6700 or 5700 with smaller footprint covers more versatile ground.
