Overview

The DN Solutions DBC 130 L II is the long-travel variant of the DBC 130 horizontal boring mill, extending all three axes for shops that handle oversized workpieces and wide bore spacing. The "L" designation means long-stroke, and it delivers meaningful extra reach on every axis without compromising the rigidity that makes the DBC 130 platform effective.

Axis travel expands to 4,000 x 2,500 x 2,000 mm (157.5 x 98.4 x 78.7 in) on X/Y/Z — that's a full meter more on X and 500 mm more on both Y and Z compared to the standard DBC 130 II. The 4,000 mm X-travel is the headline figure, letting you reach bore patterns spaced across the full length of large structural frames and turbine housings without repositioning the workpiece. The table maintains 1,800 x 1,600 mm (70.9 x 63.0 in) dimensions with 15,000 kg (33,069 lb) load capacity.

The spindle carries the same specs as the standard model: 3,000 RPM with 26 kW (35 hp) and 3,383 Nm (2,495 ft-lbs) of torque through ISO #50 taper. The extended travel doesn't dilute the cutting performance. Rapid traverse at 10 m/min (394 ipm) covers the longer distances at the same rate as the standard model.

At 48,000 kg (105,822 lb), the L II adds 5 tons over the standard 130 II to maintain rigidity across the extended travel range. The additional mass is in the bed and column structures that span the longer stroke lengths. Footprint grows to 9,970 x 8,040 mm (392.5 x 316.5 in), adding about a meter in each direction.

The 2,000 mm Z-travel is notable — that's deep enough for some workpieces that would otherwise need a floor-type boring mill. Combined with the 2,500 mm Y-travel, you can reach features on tall, deep parts that the standard 130 II can't access. This machine targets the same heavy industries — energy, mining, construction equipment — but handles the bigger components within those sectors. Competes with long-stroke HBMs from Skoda, Pama, and Union.

Strengths & Limitations

Strengths

4,000 mm X-travel reaches bore patterns across the full length of large structural components without repositioning
2,000 mm Z-travel provides deep reach that approaches floor-type boring mill capability on a table machine
2,500 mm Y-travel handles tall workpieces that the standard DBC 130 II can't fully access
Same 3,383 Nm torque and 15,000 kg table capacity as the standard model — no cutting performance compromise
48,000 kg machine weight maintains rigidity across the extended travel range
Eliminates workpiece repositioning on large parts, improving accuracy and reducing cycle time

Limitations

9,970 x 8,040 mm footprint requires significant dedicated floor space in the shop
48,000 kg machine weight demands a purpose-built foundation with engineering analysis
10 m/min rapid traverse means long positioning moves consume noticeable time across the 4,000 mm X-stroke
Price premium over the standard DBC 130 II is substantial — justified only when the extra travel is regularly needed
Long lead times for this class of machine — plan 9-15 months from order to production

Best For

Energy sector manufacturers machining large turbine housings and generator frames with widely-spaced bores Mining equipment producers handling oversized structural weldments and frames Heavy construction equipment manufacturers requiring precision boring on long frames and beams Shipbuilding operations machining large engine blocks and structural members Large job shops that handle the biggest boring work and need maximum travel flexibility

Frequently Asked Questions

01 What does the DN Solutions DBC 130 L II cost?

New DBC 130 L II pricing typically ranges from $700,000 to $1,100,000. The extended travel adds significantly to the cost versus the standard DBC 130 II ($600,000-$950,000). Foundation and installation can add another $75,000-$150,000 for a machine of this size.

02 When do I need the L variant versus the standard DBC 130 II?

If your workpieces regularly require bore spacing beyond 3,000 mm, features above 2,000 mm height, or boring depth beyond 1,600 mm, the L II is the right choice. If those situations are rare, you might handle them with workpiece repositioning on the standard model and save the cost difference.

03 How does the DBC 130 L II compare to a floor-type boring mill?

Floor-type boring mills offer unlimited X-travel (limited only by bed length) and generally handle even heavier workpieces. The DBC 130 L II offers 4,000 mm X-travel with a built-in rotary table, which simplifies 4-sided machining without floor plates and angle plates. For parts that fit within 4,000 mm X and 15,000 kg, the table-type L II is more efficient. Beyond that, you need a floor-type machine.

04 Is the DBC 130 L II available with a larger table?

The standard table is 1,800 x 1,600 mm. For larger table requirements, check with DN Solutions about the DBC 160, which steps up to a 2,200 x 2,000 mm table with 20,000 kg capacity. Custom table configurations may also be available on special order.
