What Is the DBC 130 II?

The DBC 130 II is a DN Solutions heavy-duty horizontal boring mill built for machining large, heavy workpieces with long-term accuracy and a superior surface finish. It runs a 130 mm boring spindle to 3,000 rpm on a 3-speed geared head, 3,971 Nm of spindle torque, 3,000 mm of X-axis travel, and a 15,000 kg (33,000 lb) table load capacity, with a full-rotary B-axis (360,000 positions) for four-face boring, milling, and facing in a single setup on a Fanuc 31i-B control. Ellison Technologies, the largest DN Solutions distributor in North America, supplies and supports the DBC series across its multi-state territory for shops that need to hold tight tolerances on oversized parts without repositioning.

Energy and Oil & Gas Components

Large valve bodies, pump housings, and turbine casings all demand the kind of single-setup, multi-face accuracy the DBC 130 II is built for. Its 15,000 kg table load capacity and full-rotary B-axis let shops bore, mill, and face heavy energy-sector castings on one machine, eliminating the repositioning error that stacks up when a part has to move between separate boring and milling operations. Ellison supports energy and oil & gas manufacturers with the DBC series plus spindle rebuild service to keep large-format spindles like this one running at accuracy spec over years of heavy-duty cutting.

Clean Energy and Power Generation

Wind turbine gearbox housings and large generator components are classic large-part boring work — heavy, dimensionally demanding, and expensive to scrap on a bad setup. The DBC 130 II's 3,000 mm X-axis travel and CAT 50 Big Plus spindle system give clean energy manufacturers the reach and rigidity to machine these components complete, and Ellison's applications team can pair the machine with automation for shops running repeat production of the same housing families.

Heavy Equipment and Agriculture

Frame sections, gearbox housings, and structural components for heavy equipment and agricultural machinery need a machine that won't flex under a big cut. The DBC 130 II's Meehanite cast-iron bed, wide box guide ways, and 90-tool automatic tool changer support long, unattended cutting cycles on the kind of oversized parts common in agriculture and heavy equipment manufacturing.

FAQ Section

What is the DBC 130 II used for?

The DBC 130 II is a heavy-duty horizontal boring mill for machining large, heavy workpieces that need boring, milling, and facing done in a single setup. Its 15,000 kg table capacity and full-rotary B-axis make it suited to oversized castings and structural parts in energy, power generation, and heavy equipment production.

How does a horizontal boring mill like the DBC 130 II compare to a horizontal machining center?

A horizontal boring mill adds a W-axis quill and a full-rotary B-axis table built for large single-setup boring and facing work, while a horizontal machining center is typically pallet-based and optimized for high-volume part changeover. The DBC 130 II's 700 mm W-axis travel and 360,000-position B-axis are purpose-built for oversized parts a standard HMC pallet system isn't sized to hold.

What industries is the DBC 130 II best suited for?

The DBC 130 II is best suited to manufacturers machining large, heavy components, energy and oil & gas equipment, clean energy and power generation housings, and heavy equipment and agriculture structural parts, where single-setup accuracy on oversized workpieces matters more than high-volume changeover.

What is the maximum table load capacity of the DBC 130 II?

The DBC 130 II has an allowable table load of 15,000 kg (33,000 lbs), with a 1,600 mm x 1,800 mm table and full-rotary B-axis indexing at 360,000 positions.

What CNC control does the DBC 130 II use?

The DBC 130 II runs a Fanuc 31i-B control with a 15-inch screen, including spindle load monitoring, DN Solutions Adaptive Feedrate Control, and Variable Work Load Control for heavy cutting.
