The BTH-130.R24 horizontal boring and milling machine from Toshiba Machine is designed for high rigidity, accuracy and speed. With a large work envelope and the ability to hold workpieces weighing as much as 20 metric tons (44,000 lbs), the machine is suitable for a variety of energy-related machining applications, including wind turbine components, turbine casings, natural gas fracturing (fracking) components, and oilfield and mining equipment.
To accommodate large components, the machine features a table size of 2,000 × 2,400 mm (78.7" × 94.4") and a maximum swing diameter of 3,200 mm (126"). The double-pinion-type B-axis drive mechanism provides stabilized, precision table indexing for high-speed, high-precision machining of large parts. The machine is equipped with extra-wide step-type column guideways built to withstand heavy cutting forces during aggressive machining. The spindle’s rigid, long-span-type bearings and automatic spindle end clamp provide high rigidity and accuracy during deep hole boring.
The machine comes standard with Toshiba’s Tosnuc 999 control. Four 50-taper spindle options are available, with a maximum speed and power of 4,000 rpm and 60 hp, respectively. Additional options include an automatic pallet changer, high-rigidity angle head attachment and a long-nose-type spindle extension.
