Overview

The DN Solutions DBC 130 II is a large-capacity horizontal boring mill with a 130 mm spindle bore, stepping up from the DBC 110 series for shops that need more travel, heavier table capacity, and even more torque. The 130 mm bore diameter allows larger boring bars for deeper, more rigid boring operations on heavy castings and weldments.

Axis travel stretches to 3,000 x 2,000 x 1,600 mm (118.1 x 78.7 x 63.0 in) on X/Y/Z — the 3,000 mm X-travel is particularly important for longer workpieces and multi-bore patterns spaced across large parts. The 1,800 x 1,600 mm (70.9 x 63.0 in) rotary table handles workpieces up to 15,000 kg (33,069 lb), putting this firmly in heavy-industry territory for castings, turbine housings, and large structural components.

The spindle delivers 3,000 RPM with 26 kW (35 hp) and 3,383 Nm (2,495 ft-lbs) of torque through an ISO #50 taper. That torque figure is what sets this machine apart — it's 20% more than the DBC 110 II and enables aggressive boring with large-diameter bars in deep holes. The 130 mm spindle bore accepts larger boring tools that the 110 mm machines can't accommodate, giving you more reach and rigidity on deep boring operations.

Rapid traverse at 10 m/min (394 ipm) is slightly slower than the DBC 110 series' 12 m/min, reflecting the heavier-duty construction. At 43,000 kg (94,799 lb), this machine carries serious mass for vibration dampening during heavy interrupted cuts. The 8,970 x 7,640 mm (353 x 301 in) footprint is substantial but proportional to the capability.

Servo-driven ATC provides efficient tool changes during complex multi-operation jobs. The DBC 130 II is the workhorse of DN Solutions' boring mill lineup, targeting heavy industry, energy, and construction equipment manufacturers who regularly machine parts in the 10,000-15,000 kg range. It competes with large-format HBMs from TOS Varnsdorf, Skoda, and Pama.

Strengths & Limitations

Strengths

3,383 Nm spindle torque handles the heaviest boring operations in large castings and forgings
130 mm spindle bore accepts larger boring bars than 110 mm machines for deeper, more rigid boring
15,000 kg table capacity covers most heavy-industry boring mill requirements
3,000 mm X-travel accommodates long workpieces and widely-spaced bore patterns
43,000 kg machine weight provides outstanding vibration dampening for heavy interrupted cuts
Second-generation design with proven reliability from the DBC heritage

Limitations

10 m/min rapid traverse adds non-cutting time on jobs with frequent repositioning moves
43,000 kg machine weight and 9 x 7.6 m footprint demand major foundation investment
26 kW spindle power is modest for the torque level — sustained heavy cuts may be power-limited
Large horizontal boring mills have a long lead time — expect 6-12+ months from order to installation

Best For

Heavy equipment manufacturers machining large cast iron and steel frames weighing up to 15,000 kg Energy sector operations boring turbine housings, generator frames, and large valve bodies Mining equipment manufacturers machining heavy structural components and housings Shipbuilding shops that need precision boring on large marine engine blocks and structural members Large job shops specializing in contract boring and milling of heavy industrial components

Frequently Asked Questions

01 What does the DN Solutions DBC 130 II cost?

New DBC 130 II pricing typically ranges from $600,000 to $950,000 depending on configuration and options. Foundation preparation and installation can add $50,000-$100,000 to the total project cost. Used DBC 130 machines from the Doosan era appear occasionally in the $350,000-$550,000 range.

02 What's the advantage of 130 mm spindle bore versus 110 mm?

The larger 130 mm bore accepts bigger boring bars with more cross-sectional area, which increases rigidity during deep boring operations. This matters when you're boring holes at extended lengths — the larger bar deflects less under cutting forces, maintaining accuracy on deep holes that smaller-bore machines struggle with.

03 How does the DBC 130 II compare to the DBC 130 L II?

The L II model extends X-travel to 4,000 mm (vs 3,000 mm), Y-travel to 2,500 mm (vs 2,000 mm), and Z-travel to 2,000 mm (vs 1,600 mm) while maintaining the same 15,000 kg table capacity. It's the right choice when your workpieces need the extra travel range. The L II weighs 48,000 kg vs 43,000 kg.

04 What foundation does the DBC 130 II require?

With 43,000 kg machine weight plus 15,000 kg workpiece capacity, the foundation needs to support approximately 60,000 kg total. A purpose-built reinforced concrete foundation with proper isolation from surrounding equipment is standard. Most installations require a geotechnical survey and foundation engineering specific to the site.
