Five-Axis 2-Pallet HMC for Challenging Materials

Methods Machine Tools, Inc offers its YASDA YBM 7Ti 5-axis CNC horizontal Jig Borer with a 2-position automatic pallet changer.

"The YASDA YBM 7Ti features the industry's highest accuracy and performance required to machine the most difficult-to-cut materials," said a company spokesperson. "A unique rotary table design and exceptionally rigid machine structure provide high performance machining of heat-resistant materials, such as titanium and Inconel. To ensure high accuracy levels, the YBM 7Ti has hardened box guideways and a 10,000 RPM, 50-taper direct-drive spindle." The machine is also available with a 6-pallet APC.

"The rotary table on the YBM 7Ti offers four times the rigidity compared to other rotary tables. With a unique table design, there is ample room around the pallet which provides smooth table movements and allows operators to get a closer and clearer view of their parts," continued the spokesperson.

The YASDA YBM 7Ti features a 25-ton, H-shaped steel machine base for absorbing cutting forces and minimizing any machine vibration. All axes have hand-scraped, hardened box guideways for high accuracy when making challenging cuts. Hardened, ground and lapped guideways enable rapid feeds of up to 48 m/min, yielding high accuracy throughout every full stroke. "To achieve maximum performance levels, the mating faces of the guideways are approximately double the width of more traditional guideways," said the spokesperson.

The YASDA YBM 7Ti features a direct-drive spindle system that is designed to keep cutting forces away from the spindle motor, which maintains consistency and repeatability. A YASDA self-adjusting spindle system automatically adjusts the preload to the spindle bearings, enabling a wider range of cutting capabilities.

YASDA HMCs have a large work envelope with X, Y, Z travels of 49.2" x 39.4" x 43.3" (1,250 mm x 1,000 mm x 1,100 mm) respectively, a vertical rotation of 360° and a horizontal rotation of +/- 110°. A two-pallet system has 19.7" x 19.7" (500 mm x 500 mm) pallets for a maximum loading capacity of 1,102 lbs. (500 kg) on each pallet. Maximum part size is 24.8" (630 mm) in diameter and 19.7" (500 mm) in height. A YASDA curvic coupling system with large diameter circle gears is used to support the back side of the pallet, allowing the accuracy of the center of the pallet to be fully maintained. An automatic tool changer holds up to 450 tools. The powerful, new easy-to-use FANUC FS31i-B5 control is furnished standard.
