Kuraki KBT-11DX vs Kuraki KBT-13A
Kuraki vs Kuraki · CNC Boring Machines
Summary
The Kuraki KBT-11DX and Kuraki KBT-13A are table-type CNC boring machines from the same builder, both on a Fanuc 31i-B control. The KBT-13A is the larger of the two: 2,500 x 2,000 x 1,500 mm of travel against 1,800 x 1,400 x 1,200 mm, and a 15,000 kg (33,069 lb) table load against 8,000 kg (17,637 lb).
The KBT-13A also has the bigger spindle motor, 30 kW (40 HP) against 22 kW (30 HP), and offers a 60-tool ATC option against 40 tools on the KBT-11DX. The KBT-11DX answers with a wider speed range, 5 - 3,000 RPM against 5 - 2,000 RPM, and faster rapids at 10 m/min (394 IPM) against 8 m/min (315 IPM). It is also the lighter machine at 22,000 kg against 32,000 kg.

Verdict
Size the machine to the casting. The Kuraki KBT-11DX suits medium housings, gearboxes and pump bodies up to 8,000 kg, where its 3,000 RPM top speed and 10 m/min rapids help on smaller bores and mixed work. The Kuraki KBT-13A is for heavy castings and weldments in mining, power generation and shipbuilding that need 2,500 mm of X travel, a 15,000 kg table and 30 kW at the spindle.
