Kuraki vs Shibaura Machine · CNC Boring Machines
Summary
The Kuraki KBT-11DX and the Toshiba BTD-200QH are both CNC boring machines for medium-to-large castings and weldments. The Kuraki has the larger envelope, with 1,800 x 1,400 x 1,200 mm of travel against 1,500 x 1,200 x 700 mm, and the gap is widest on Z: 1,200 mm against 700 mm.
The Toshiba has the stronger spindle motor at 30 kW (40 hp) against 22 kW (30 HP). Both reach 3,000 RPM as standard; the Kuraki lists a 5 - 3,000 RPM range, while the Toshiba offers a 5,000 RPM high-speed option. The Kuraki runs a Fanuc 31i-B and weighs 22,000 kg (48,502 lb); the Toshiba uses a TOSNUC 999 CNC and weighs 18,000 kg (39,600 lb).

Advantages
Kuraki KBT-11DX
- 1,800 mm (70.9 in) X travel against 1,500 mm (59.1 in)
- 1,200 mm (47.2 in) Z travel against 700 mm (27.6 in)
- 1,400 mm (55.1 in) Y travel against 1,200 mm (47.2 in)
Toshiba BTD-200QH
- 30 kW (40 hp) spindle against 22 kW (30 HP)
- 5,000 RPM high-speed spindle option, where the Kuraki tops out at 3,000 RPM
- Lighter at 18,000 kg (39,600 lb) against 22,000 kg (48,502 lb)
Verdict
The Kuraki KBT-11DX is the choice when part size is the limit: its 1,800 mm X and 1,200 mm Z travel take bigger housings and gearbox bodies in one setup. The Toshiba BTD-200QH suits shops that want more spindle power and the option of 5,000 RPM, such as mold base and die set work, and those that rely on its W-axis quill for deep bores beyond the 700 mm Z stroke.
