YASDA YBM 8T HORIZONTAL MACHINING CENTER

Technical Description

The Yasda YBM 8T is a high-precision horizontal machining center featuring a robust H-shaped solid steel bed with reinforced double cast iron columns for exceptional rigidity and thermal stability. It offers a large 31.5" x 31.5" (800 x 800 mm) work table, supporting up to 6,600 lbs (3,000 kg) of workpiece weight. The machine operates with a 4-axis configuration including a full 360° B-axis rotation, optimized for high-accuracy complex machining tasks. Its spindle is a #50 taper design, rated at 30 HP for continuous operation with optional upgrades to 40 HP, spinning up to 10,000 rpm standard, with a 15,000 rpm upgrade option for high-speed machining. The spindle incorporates a pre-load self-adjusting system to maintain consistent precision across the speed range. The travel capacities are ample, with 51.18" (X), 39.37" (Y, optional 49.21"), and 43.31" (Z, optional 55.12"), with rapid traverse rates up to 1,886 ipm on all axes, ensuring efficient material removal. The machine features YASDA’s traditional hybrid box guideways driven by twin ball screws paired with optical scale feedback, enhancing positioning accuracy down to microns (2.6µm linear accuracy). Tool capacity is supplied by an automatic tool changer (ATC) with 60 tools standard, expandable to 450 tools. Pallet changers are optional, supporting 2 pallets standard and up to 5 pallets for flexible workholding. This machining center is engineered for demanding aerospace, automotive, and mold applications where high rigidity, thermal stability, and ultra-precision are critical to machining difficult materials and complex geometries.
