DN Solutions DBC-130 vs Mitsui Seiki H6D
DN Solutions vs Mitsui Seiki · CNC Boring Machines
Summary
The DN Solutions DBC-130 and the Mitsui Seiki H6D are both listed as CNC boring machines, but they serve different jobs. The DBC-130 is a large borer with 3,000 x 2,000 x 1,600 mm of travel, a 1,600 × 1,800 mm table and a 15,000 kg (33,000 lb) load. The H6D is a compact precision machine with 600 x 700 x 500 mm of travel, a 630 x 500 mm table and an 800 kg (1,764 lb) load.
The DBC-130 also has 45 kW (60 hp) against 15 kW (20 HP) and 90 tools against 30. The H6D runs faster, 6,000 rpm against 3,000 rpm, with 15 m/min (591 ipm) rapids against 10 m/min (393 in/min). Both use the Fanuc 31i-B control.

Advantages
DN Solutions DBC-130
- 3,000 x 2,000 x 1,600 mm of travel against 600 x 700 x 500 mm
- 15,000 kg (33,000 lb) table load against 800 kg (1,764 lb)
- 45 kW (60 hp) spindle against 15 kW (20 HP) continuous
- 90 tools standard against 30 tools
Mitsui Seiki H6D
- 6,000 rpm spindle against 3,000 rpm
- 15 m/min (591 ipm) rapids against 10 m/min (393 in/min)
- A 9,000 kg (19,842 lb) machine against 43,000 kg (94,800 lb)
Verdict
Part size and tolerance decide. The DBC-130 is for heavy castings, weldments and mold bases that need 3,000 mm of X travel and a 15,000 kg table. The Mitsui Seiki H6D is for hydraulic manifolds, valve and actuator housings, and pump bodies within a 630 x 500 mm table, where precise bore relationships across several faces matter more than size. These machines rarely compete for the same part.
