The Vertex 100 5-axis vertical machining center from Mitsui Seiki USA, Inc. (Franklin Lakes, NJ) is engineered to fulfill shop demands for a compact, high-speed machine that is capable of high-precision milling of larger parts, such as blisks for aircraft engines. It machine workpieces 1,250 mm diameter and 850 mm tall in only 3 m x 4.2 m of shop floor space. X-Y-Z axis strokes are 1,000 mm, 900 mm and 750 mm, respectively. Maximum swing diameter is 1,480 mm. From CAT 40 to HSK-A100 taper sizes, the Vertex 100 is supplied with multiple spindle options (15,000 rpm, 25,000 rpm and 30,000 rpm). A large 60-tool standard automatic tool changer handles maximum tool lengths of 300 mm and maximum tool diameters of 125 mm (CAT 40/HSK-A63) or 160 mm (CAT 50/ HSK-A100), offering maximum flexibility for job shop applications. Larger capacity tool changers are an additional option. This machine’s tilt/rotary table is supported by a rigid and robust cast iron base to provide high precision and rotation speed up to 100 rpm. The table’s C-axis motors are direct-drive, while the A-axis has tandem direct-drive motors. The machine is capable of machining workpieces up to 1,250 mm (49.25 in) diameter.
The X- and Z-axes are driven by single ballscrews, with dual ballscrews on the Y-axis. The linear axes are capable of fast 1G acceleration and deceleration. The FANUC control features a state-of-the-art 375 mm (14.75 in) LCD HMI. In addition to providing a large work envelope relative to the machine footprint, the Vertex 100 has numerous features that assure accuracy and consistency. The machine features a proprietary cast iron bed and a solid “box-in-box” design that provide superior rigidity, stiffness and agility. Its innovative machine geometry results in positioning accuracy in the X, Y, and Z-axes of 0.001 mm (0.000040 in), ±6 arc seconds in A-axis and ±4 arc seconds in the C-axis. Hand-scraped guideways maximize precision. An advanced thermal compensation system assures size consistency, and glass scales provide minimum resolution of 0.001 mm.
