DN Solutions vs Kuraki · CNC Boring Machines
Summary
The DN Solutions DBC-130 and the Kuraki KBT-11DX are table-type horizontal boring machines, both on the Fanuc 31i-B control with a 3,000 rpm top spindle speed and 10 m/min rapids. The DBC-130 is the larger machine in every measured dimension.
It offers 3,000 x 2,000 x 1,600 mm of travel against 1,800 x 1,400 x 1,200 mm, a 15,000 kg (33,000 lb) table load against 8,000 kg (17,637 lb), and 45 kW (60 hp) against 22 kW (30 HP). It carries 90 tools standard, where the Kuraki's 40-tool ATC is an option. The KBT-11DX is the lighter machine at 22,000 kg (48,502 lb) against 43,000 kg (94,800 lb), and is aimed at medium-sized castings, gearbox housings and pump bodies.

Advantages
DN Solutions DBC-130
- 3,000 x 2,000 x 1,600 mm of travel against 1,800 x 1,400 x 1,200 mm
- 15,000 kg (33,000 lb) table load against 8,000 kg (17,637 lb)
- 45 kW (60 hp) spindle against 22 kW (30 HP)
- 90 tools standard against an optional 40-tool ATC
Kuraki KBT-11DX
- Lighter at 22,000 kg (48,502 lb) against 43,000 kg (94,800 lb)
- Sized for medium castings and housings that do not need 3,000 mm of X travel
Verdict
The DBC-130 is the choice for large castings, weldments and mold bases up to 15,000 kg, where its 45 kW spindle and 90-tool magazine support heavy boring and long unattended runs. The Kuraki KBT-11DX suits shops whose gearbox, pump and compressor housings fit within 1,800 x 1,400 x 1,200 mm and 8,000 kg, where the larger machine's reach and weight would go unused.
