IMTS 2012: Horizontal Boring and Milling Machine

Sept. 3, 2012
High-rigidity, high accuracy and high-speed machining Large work envelope for a series of oversized machining applications High rigidity and accuracy for deep-hole boring

Toshiba Machine will be featuring its BTH-130.R24 Horizontal Boring & Milling Machine, with a large work envelope and the ability to hold workpieces up to 20 metric tons (44,000 lbs.) The scale of the design makes BTH-130.R24 suitable for a variety of large machining applications, including turbine components and casings, jet engine and rocket components, natural gas fracturing (fracking) components, and oilfield and construction equipment.

Toshiba Machine Co. Ltd. includes approximately 30 regional companies supplying products that include machine tools, plastic injection molding machines, diecasting machines, robotics equipment and semiconductor manufacturing equipment.

The machine builder stated that its BTH-130.R24 embraces the Toshiba Machines H3 design philosophy: high-rigidity, high accuracy and high-speed. The extra-wide step-type column guideways are built to withstand heavy cutting forces during aggressive machining. The spindle’s extremely rigid, long-span type bearings and automatic spindle end clamp provide high rigidity and accuracy during deep-hole boring.

To accommodate large components, the BTH-130.R24 boasts a table size of 2,000 mm by 2400 mm (78.7 in. x 94.4 in.), and a maximum swing diameter of 3,200 mm (126.0 in.). The patent-pending, double-pinion type B-axis drive mechanism provides stabilized precision table indexing for high-speed, high-precision machining of even the largest parts.

The machine comes standard with Toshiba’s latest version of their TOSNUC 999 control. Four 50 taper spindle options are available, with a maximum of 4,000 RPM and 60 horsepower. Additional options include an automatic pallet changer, high rigidity angle head attachment and a long nose type spindle extension.
