Overview

The DN Solutions DBC 130 II is a large-format horizontal boring mill from DN Solutions' best-selling DBC series, with over 1,000 units sold worldwide. With axis travels of 3,000 x 2,000 x 1,600 mm (118 x 79 x 63 in), the DBC 130 II provides the massive work envelope needed for machining large castings, weldments, and structural components found in energy, shipbuilding, heavy construction, and defense industries. The 1,800 x 1,600 mm (71 x 63 in) rotary table supports workpieces up to 15,000 kg (33,069 lb), handling the heaviest parts in any machine shop.

The 130 mm (5.1 in) spindle bore delivers 26 kW (35 hp) with an extraordinary 3,383 Nm (2,495 ft-lb) of torque through an ISO 50 taper at up to 3,000 RPM. This massive torque output enables large-diameter boring, facing, and milling operations that define horizontal boring mill work. The 130 mm spindle diameter provides the rigidity needed for long boring bar extensions into deep bores and cavities. Rapid traverse of 10 m/min (394 ipm) on all axes reflects the machine's precision-oriented heavy-duty nature.

At 43,000 kg (94,799 lb), the DBC 130 II is a capital machine built on massive castings with precision-scraped box guideways that provide the geometric accuracy and vibration damping essential for boring operations. The machine's footprint of 8,970 x 7,640 x 5,070 mm (353 x 301 x 200 in) demands dedicated floor space and foundation engineering. The FANUC 0i-Plus control with boring-specific cycles and conversational programming simplifies setup for the large, complex parts typical of boring mill work. The DBC 130 competes with the Kuraki KBT-13DX, Toshiba BTD-130, and PAMA Speedram in the medium horizontal boring mill segment.

Strengths & Limitations

Strengths

3,383 Nm spindle torque through a 130 mm bore provides the power and rigidity for heavy boring, facing, and milling operations in large workpieces
15,000 kg table load capacity handles the heaviest castings and weldments found in energy, shipbuilding, and heavy industry
Over 1,000 DBC series units sold worldwide—a proven platform with established reliability and service history
3,000 x 2,000 x 1,600 mm travel envelope covers most large-part machining requirements without supplementary machines
Precision-scraped box guideways provide geometric accuracy and vibration damping critical for precision boring operations

Limitations

43,000 kg machine weight requires significant foundation engineering including isolated concrete pads and leveling systems
10 m/min rapid traverse is slow, adding substantial non-cutting time during positioning moves
3,000 RPM maximum spindle speed limits high-speed finishing operations on smaller features
Large footprint (8,970 x 7,640 mm) demands extensive dedicated floor space

Best For

Energy sector manufacturers machining large turbine housings, valve bodies, and pressure vessel components Shipbuilding and marine engineering shops boring and milling large structural castings and weldments Heavy construction equipment manufacturers machining large frames, housings, and structural components Defense and aerospace manufacturers requiring large-format boring and milling of heavy structural parts

Frequently Asked Questions

01 What does a DN Solutions DBC 130 cost?

A new DN Solutions DBC 130 II typically runs between $600,000 and $1,200,000 depending on configuration and travel options. The DBC 130S (shorter travel: 2,000 x 1,500 x 1,200 mm) starts around $600,000-$750,000. The DBC 130 II (full travel: 3,000 x 2,000 x 1,600 mm) ranges from $800,000-$1,200,000 depending on options including automatic tool changer, facing head, and angular milling head. Used DBC 130 machines typically sell for $200,000-$500,000 depending on age and condition.

02 What is the difference between the DBC 130S and DBC 130 II?

The DBC 130S is the compact variant with 2,000 x 1,500 x 1,200 mm of travel, while the DBC 130 II is the full-size variant with 3,000 x 2,000 x 1,600 mm of travel. Both use the same 130 mm spindle bore and share the same spindle, control, and construction quality. The DBC 130S is suited for shops with smaller large-part requirements, while the DBC 130 II handles the biggest workpieces. The DBC 130 II weighs 43,000 kg versus approximately 30,000 kg for the DBC 130S.

03 What makes a horizontal boring mill different from an HMC?

Horizontal boring mills (HBMs) like the DBC 130 are designed for machining very large, heavy workpieces (15,000+ kg) with long boring bar operations, facing operations, and milling on massive parts. They feature large spindle bores (130 mm on the DBC 130), massive table load capacity, and precision-scraped box guideways. HMCs are smaller, faster machines optimized for production of medium-sized parts with pallet changers and higher spindle speeds. HBMs are job-shop machines for large parts; HMCs are production machines for medium parts.

04 Can the DBC 130 use automatic tool changing?

Yes. The DBC 130 can be configured with an automatic tool changer, though many boring mill applications use manual tool changes due to the large, specialized tooling involved. Optional facing heads and angular milling heads extend the machine's capability for operations that would otherwise require repositioning the workpiece. The FANUC 0i-Plus control supports automatic tool management when the ATC option is installed.
