Overview

The DN Solutions DBD 130 is a duplex horizontal boring mill that doubles the productivity of the proven DBC 130 platform by mounting two independent spindle columns on a shared bed. Each column carries a 130 mm (5.1 in) spindle bore with ISO 50 taper, allowing simultaneous machining of opposite faces of large workpieces or parallel processing of two setups on the same table. This duplex configuration cuts cycle times nearly in half on large prismatic parts like engine blocks, gearbox housings, turbine casings, and structural weldments.

Axis travel runs 7,000 x 1,500 x 1,000 mm (276 x 59 x 39 in) on X/Y/Z per column. The generous X-axis travel accommodates very long workpieces between the two columns, while the shared table spans 7,000 x 1,250 mm (276 x 49 in) with a 10,000 kg (22,046 lb) load capacity. Each spindle delivers 26 kW (35 hp) with up to 1,986 Nm (1,465 ft-lb) of torque at speeds up to 3,000 RPM — substantial power for heavy boring, facing, and milling operations.

The duplex layout is particularly effective for parts requiring precise alignment between opposing bored features, since both operations happen in a single setup without re-fixturing. This eliminates the tolerance stack-up and setup time that come with flipping heavy parts on a single-column machine. Rapid traverse of 12 m/min (472 ipm) on all axes keeps non-cutting time manageable despite the large travel distances.

At approximately 58,000 kg (127,868 lb), the DBD 130 requires serious foundation engineering and dedicated floor space of roughly 19,100 x 10,400 mm (752 x 409 in). The FANUC 0i-Plus control manages both columns with synchronized or independent operation modes. Box guideways on all axes provide the vibration damping essential for precision boring. The DBD 130 competes with duplex boring mills from Pama, SNK, and Toshiba in the heavy-industry segment.

Strengths & Limitations

Strengths

Dual independent spindle columns enable simultaneous two-sided machining, cutting cycle times nearly in half on large symmetric parts
Eliminates re-fixturing for opposing bore features — both sides machined in a single setup, removing tolerance stack-up from part flipping
1,986 Nm torque per spindle through 130 mm bores provides serious power for heavy boring, facing, and milling on large castings and weldments
7,000 mm X-axis travel accommodates very long workpieces between the two columns
Built on the proven DBC 130 platform with over 1,000 units of the DBC series sold worldwide

Limitations

58,000 kg machine weight demands significant foundation engineering including reinforced concrete isolation pads
19,100 mm overall length requires substantial dedicated floor space that many shops cannot accommodate
3,000 RPM maximum spindle speed limits high-speed finishing capability on smaller features
Capital cost is roughly double that of a single-column DBC 130, requiring sufficient duplex workload to justify the investment

Best For

Engine and powertrain manufacturers boring both sides of large blocks and housings in a single setup Energy sector shops machining large turbine casings, valve bodies, and pump housings requiring aligned opposing bores Shipbuilding and heavy equipment manufacturers processing long structural weldments and castings High-volume heavy-industry production where dual-spindle cycle time reduction justifies the capital investment

Frequently Asked Questions

01 What does a DN Solutions DBD 130 cost?

A new DN Solutions DBD 130 typically falls in the $1,200,000 to $2,500,000 range depending on travel configuration, tooling packages, and automation options. The duplex configuration commands a significant premium over the single-column DBC 130 ($600,000-$1,200,000) due to the second spindle column and expanded bed. Used DBD-series machines are rare on the secondary market but when available typically sell in the $400,000-$900,000 range.

02 How does the DBD 130 compare to the single-column DBC 130?

The DBD 130 adds a second independent spindle column to the DBC 130 platform, enabling simultaneous machining of two faces. The DBC 130 has travel of 3,000 x 2,000 x 1,600 mm with a single spindle; the DBD 130 stretches X-travel to 7,000 mm to accommodate both columns with a workpiece between them. The DBD trades the DBC's larger Y and Z travel for dual-spindle productivity. If your parts have opposing features that need machining, the DBD 130 can cut cycle times nearly in half.

03 Can both spindles operate simultaneously on the same workpiece?

Yes, both spindle columns operate independently with full X/Y/Z travel per column. The FANUC control manages synchronization when needed or allows fully independent operation. This is the primary advantage — both sides of a large workpiece can be bored, faced, or milled simultaneously. The columns can also work on separate workpieces fixtured at different positions along the table.

04 What foundation requirements does the DBD 130 need?

At 58,000 kg, the DBD 130 requires a reinforced concrete isolation pad engineered specifically for the machine. Foundation depth typically runs 800-1,200 mm depending on soil conditions. The 19,100 x 10,400 mm footprint plus service access space means you need roughly 25 x 15 meters of dedicated floor area. DN Solutions provides foundation drawings and specifications as part of the installation package.
