HITACHI SEIKI VK55 II VERTICAL MACHINING CENTER

Technical Description

This CNC machining center features a robust 4-axis design with extensive travel ranges: 40 inches on the X-axis, 23.6 inches on the Y-axis, and 19.7 inches on the Z-axis, enabling versatile machining capabilities. It incorporates a powerful 11.2 kW spindle motor delivering speeds from 60 to 8,000 RPM, with an RPM maximum of 6,000, and a spindle taper of Cat 40 for compatibility with a wide range of tooling. The machine is equipped with a 20-tool automatic tool changer (ATC), enhancing operational efficiency and reducing tool change time. The 55.1-inch wide by 22-inch long table supports large workpieces, with rapid traverse rates of 1,180 IPM (X-axis), 787 IPM (Y-axis), and 394 IPM (Z-axis) for swift repositioning. The spindle motor power ranges from 7.5 to 10 HP, driving the 10-inch chuck with a 2 7/8-inch through bore, suitable for substantial workpieces requiring through-spindle machining. Overall machine dimensions are 136 inches by 120 inches by 90 inches, with a weight of 17,500 lbs, reflecting a sturdy build designed for stability and precision. This configuration supports high productivity and precision manufacturing across various applications, with a balance of powerful spindle performance, extensive machining volume, and fast axis movement. The inclusion of four axes allows for complex geometries and orientations in workpieces, suited for advanced milling tasks in automotive, aerospace, tooling, and general manufacturing environments.
