Overview
The DN Solutions DBC 250 L II combines boring-mill travels with a spindle that runs to 6,000 rpm. The axes cover 4,000 × 2,500 × 2,000 mm (157 × 98 × 79 in), the 1,800 × 1,600 mm (71 × 63 in) table is rated for 15,000 kg (33,069 lb), and the ISO 50 spindle is listed at 30 kW (40 hp) and 600 N·m (443 ft-lb).
That spindle is the reason to pick this model. Its frame figures repeat those of the DBC 130 L II row for row: the same travels, table, table load, per-axis rapids and 48,000 kg (105,822 lb) machine weight. The DBC 130 L II turns at up to 3,000 rpm with 3,383 N·m (2,495 ft-lb). The DBC 250 L II doubles the speed and has about 82% less torque, so it behaves like a large-envelope milling machine: end mills, indexable cutters of moderate diameter, drilling and tapping at proper surface speeds, and finishing passes on big parts in aluminium or other free-cutting materials.
It is the wrong choice for the work boring mills are usually bought for. A large boring bar or a wide face mill in steel wants torque at low speed, and 600 N·m is a fraction of what the DBC 130 L II or the 3,900 N·m (2,876 ft-lb) DBC 160 supply. A shop that needs both kinds of cutting on one part has to decide which side of the job costs more time.
Positioning is listed axis by axis at 10 m/min (394 ipm) in X and Z and 8 m/min (315 ipm) in Y. Those are boring-mill rates, so on light cuts the moves between features, not the spindle, will set the pace. DN Solutions gives the outline as 9,970 × 8,040 × 5,570 mm (393 × 317 × 219 in).

Strengths & Limitations
Strengths
- 6,000 rpm maximum spindle speed, double the 3,000 rpm of the DBC 130 L II on the same travels
- 30 kW (40 hp) spindle power on an ISO 50 taper
- 4,000 mm (157 in) of X, 2,500 mm (98 in) of Y and 2,000 mm (79 in) of Z
- 15,000 kg (33,069 lb) table load, equal to the DBC 130 L II and DBC 130 II
- 2,000 mm (79 in) of Z travel against 1,600 mm (63 in) on the DBC 160
Limitations
- Torque is 600 N·m (443 ft-lb), about 82% below the 3,383 N·m (2,495 ft-lb) of the DBC 130 L II, which rules out heavy low-speed boring
- Rapid traverse of 10 m/min (394 ipm) in X and Z and 8 m/min (315 ipm) in Y is slow for a spindle of this speed
- The 1,800 × 1,600 mm (71 × 63 in) table is small next to 4,000 mm (157 in) of X; the DBC 160 has a 2,200 × 2,000 mm (87 × 79 in) table
- No tool magazine capacity, control or coolant data in DN's table for this model

Frequently Asked Questions
01
Only the spindle rows differ. The DBC 250 L II is listed at 6,000 rpm, 30 kW (40 hp) and 600 N·m (443 ft-lb). The DBC 130 L II is listed at 3,000 rpm, 26/22 kW (35/29 hp) and 3,383 N·m (2,495 ft-lb). Travels, table size, the 15,000 kg (33,069 lb) table load, the rapids and the 48,000 kg (105,822 lb) weight are the same.
02
Not well. Heavy boring and wide face milling depend on torque at low spindle speed, and this spindle offers 600 N·m (443 ft-lb). For that work the DBC 130 L II with 3,383 N·m (2,495 ft-lb) or the DBC 160 with 3,900 N·m (2,876 ft-lb) and 45 kW (60 hp) are the matching models.
03
The table measures 1,800 × 1,600 mm (71 × 63 in) and carries 15,000 kg (33,069 lb). The spindle can reach across 4,000 mm (157 in) in X, 2,500 mm (98 in) in Y and 2,000 mm (79 in) in Z, which is far more than the table size, so long parts can overhang the table as long as they are supported and within the load rating.
04
ISO 50, the same taper as the high-torque DBC models. Running a 50-taper spindle at 6,000 rpm puts more demand on holder balance than low-speed boring does, so check the balance grade of existing tooling before moving it across from a slower machine.
05
The listed dimensions are 9,970 mm in length, 8,040 mm in width and 5,570 mm in height (393 × 317 × 219 in), and the machine weighs 48,000 kg (105,822 lb). Foundation, lifting and roof clearance have to be planned around those numbers.
