Overview

The DN Solutions DBC 110 II is a medium-to-large capacity horizontal boring mill with a 110 mm spindle bore, built for precision machining of large workpieces that demand heavy material removal and tight tolerances. The "II" designation indicates this is the second generation, with improvements to rigidity, thermal stability, and control integration over the original DBC 110.

Axis travel spans 2,500 x 2,000 x 1,500 mm (98.4 x 78.7 x 59.1 in) on X/Y/Z, providing a generous working envelope for large castings, fabrications, and structural components. The 1,800 x 1,400 mm (70.9 x 55.1 in) rotary table handles workpieces up to 10,000 kg (22,046 lb), which covers most mid-range boring mill work in heavy industry, energy, and construction equipment manufacturing.

The spindle runs at 4,000 RPM with 26 kW (35 hp) and an impressive 2,827 Nm (2,085 ft-lbs) of torque through an ISO #50 taper. That torque is what you buy a boring mill for — it lets you push large face mills, boring bars, and heavy endmills through cast iron and steel without worrying about stalling. The ISO #50 taper is the standard interface for this class of machine, compatible with the widest range of heavy-duty tooling.

Rapid traverse runs at 12 m/min (472 ipm), which is typical for horizontal boring mills of this size. You're not buying this machine for rapid transit speed — you're buying it for the massive torque and rigidity that make it possible to hold tight tolerances on large, heavy parts over long machining cycles.

DN Solutions emphasizes the compact structure and minimized footprint of the DBC 110 II, which is notable at 6,990 x 7,630 mm (275 x 300 in). For a machine that handles 10-ton workpieces, that's relatively tight. A servo-driven automatic tool changer keeps the machine running during complex multi-operation jobs. At 36,000 kg (79,366 lb), the machine provides the mass needed for vibration-free heavy cutting. The DBC 110 II competes with boring mills from Doosan's own legacy, Kuraki, TOS, and SNK.

Strengths & Limitations

Strengths

2,827 Nm spindle torque drives heavy boring bars and face mills through cast iron and steel without stalling
10,000 kg table load capacity handles large castings and fabrications typical of heavy industry work
Compact footprint relative to working envelope and table capacity saves shop floor space
Servo-driven ATC keeps the machine productive during multi-operation jobs without manual intervention
Second-generation design with improved rigidity and thermal stability over the original DBC 110
4,000 RPM max speed provides good versatility for both heavy boring and lighter milling operations

Limitations

12 m/min rapid traverse is slow compared to VMCs — non-cutting time adds up on jobs with many repositioning moves
36,000 kg machine weight requires significant foundation preparation and rigging capacity for installation
Large footprint at nearly 7 x 7.6 meters demands dedicated floor space in the shop layout
ISO #50 taper horizontal boring mills are a mature market — used options from other brands may offer better value

Best For

Heavy equipment manufacturers machining large castings, frames, and structural components Energy sector shops boring valve bodies, pump housings, and turbine casings Construction equipment manufacturers machining excavator frames and heavy structural weldments General heavy industry operations that need precision boring on 5,000-10,000 kg workpieces Job shops specializing in large-part machining for oil and gas, mining, and power generation

Frequently Asked Questions

01 What does the DN Solutions DBC 110 II cost?

New DBC 110 II pricing typically falls between $500,000 and $800,000 depending on configuration, tooling package, and options like probing and additional axes. Used DBC-series boring mills from the Doosan era occasionally appear in the $250,000-$450,000 range.

02 What's the difference between the DBC 110 II and the DBC 110 S?

The DBC 110 II is the larger machine with 2,500 mm X-travel (vs 2,000 mm), 2,000 mm Y-travel (vs 1,500 mm), a 10,000 kg table capacity (vs 7,000 kg), and higher spindle torque at 2,827 Nm (vs 1,104 Nm). The S model is the more compact, lighter-duty option for smaller work.

03 Can the DBC 110 II do milling as well as boring?

Yes. While it's optimized for boring operations, the 4,000 RPM spindle with ATC handles face milling, pocket milling, drilling, and tapping operations. Many shops use horizontal boring mills as multi-function machines for large parts, completing boring, milling, and drilling in a single setup.

04 What kind of foundation does the DBC 110 II need?

At 36,000 kg machine weight plus up to 10,000 kg workpiece, you need a foundation designed for approximately 50,000 kg total. Most installations require a dedicated reinforced concrete foundation or pit, engineered for the specific soil conditions. Get a site survey before ordering.
