Technical Description

The TOSHIBA BTD-110H.R16 is a robust Horizontal Boring Mill controlled by a CNC TOSNUC 999 system. It features a 4.3-inch (110 mm) diameter spindle with a CAT 50 / #50 ISO taper, capable of speeds from 5 to 3,000 RPM, driven by a 30 HP / 35 HP motor. The machine offers substantial travel capacities, including 78.7 inches (2000 mm) in the X-axis (Table Cross Travel), 59 inches (1500 mm) in the Y-axis (Vertical Head Travel), and 57 inches (1450 mm) in the Z-axis (Spindle Travel), plus a W-axis travel of 15.7 to 19.7 inches. The rotary table measures 55 inches by 63 inches and can handle a maximum load capacity of 13,860 lbs, featuring high indexing accuracy (0.0001 degree). Key features contributing to precision and rigidity include a high-precision spindle designed for minimal thermal displacement, closed-loop control with 1 μm linear scales on the X, Y, Z, and B axes, step-type column guideways, and a high-precision B-axis with a double gear drive. The machine has a rapid traverse rate of 394 inches per minute and weighs approximately 61,600 to 63,800 lbs.
