KURAKI KBH-22 HORIZONTAL BORING MILL

The KURAKI KBH-22 HORIZONTAL BORING MILL is a high-speed CNC machine featuring a 7.87-inch (200 mm) spindle, typically utilizing a #50 ISO taper. Power is supplied by a 40 HP main drive motor, enabling spindle speeds ranging from 5 to 3,000 RPM, with certain versions capable of reaching up to 12,000 RPM. This mill is configured with significant travel capabilities, including X-axis horizontal travel of 100 inches (2540 mm), Y-axis vertical head travel of 65 inches (1651 mm), and Z-axis column infeed of 45 inches (1143 mm). Additionally, the spindle (W) has a travel of 20 inches (508 mm). The machine is equipped with a large table, with standard plain tables measuring approximately 80 inches by 55 inches (2032 mm x 1397 mm), capable of handling a load capacity between 40,000 and 44,000 lbs. Rapid traverse rates reach up to 472.4 IPM for the main axes. Control options include advanced CNC systems such as Tosnuc 888 or various Fanuc models (e.g., 16i-M / 31i-MB). Key features include an automatic tool changer with 38 to 60 stations, through-spindle coolant capability, and robust construction utilizing hardened and ground box ways on the X, Y, and Z axes.
