Available from Methods Machine Tools, the Yasda YBM 7Ti five-axis CNC horizontal jig borer is designed for high precision in difficult-to-machine, heat-resistant materials like titanium and Inconel.

The company says its rotary table design is more rigid than other varieties and provides ample room around the pallet. This facilitates smooth table movements and allows operators to get a closer and clearer view of parts.The 50-taper, 10,000-rpm spindle features a direct-drive system designed to keep forces away from the motor to maintain consistency and repeatability. Automatic adjustment of spindle bearing preload ensures an expansive application range.

To absorb cutting forces and damp vibration, the machine features a 25-ton, H-shaped steel base. All axes have hand-scraped, hardened box guideways . Hardened, ground and lapped guideways enable feeds as fast as 48 m/min. According to the company, the mating faces of the guideways are approximately double the width of more traditional guideways.

The machine has a large work envelope, with XYZ-axis travels measuring 49.2" × 39.4" × 43.3" (1,250 × 1,000 × 1,100 mm), a vertical rotation of 360 degrees and a horizontal rotation of ±110 degrees. A two-pallet system has 19.7" × 19.7" (500 × 500 mm) pallets for a maximum loading capacity of 1,102 lbs (500 kg) on each pallet. A six-station automatic pallet changer is also available.
