1990 HITACHI-SEIKI VK45 VERTICAL MACHINING CENTERS

Technical Description

The 1990 Hitachi Seiki VK45 is a 3-axis vertical machining center from Hitachi Seiki Co., Ltd. of Japan, built on the VK-series platform that succeeded and refined the VA-series design. The VK45 provides an X-axis travel of 30 inches, a Y-axis travel of 19.7 inches, and a Z-axis travel of 19.7 inches, served by a 44.1-inch by 19.1-inch T-slotted worktable. The 10 HP spindle motor drives a CAT-40 taper spindle to a maximum of 6,000 RPM on earlier units. The Fanuc CNC control provides comprehensive G-code programming, canned drilling, boring, and tapping cycles, and the positioning accuracy characteristic of Hitachi Seiki's engineering standards. The machine's rigid cast-iron construction and precision ballscrew drives on all three axes deliver consistent positioning repeatability and surface finish quality across extended production cycles. The automatic tool changer supports multi-operation programs for complex part machining in a single setup. Hitachi Seiki's VK-series machines built a strong reputation in North American, Japanese, and European markets for their mechanical durability and precision, carrying forward the engineering heritage established with the earlier VA-series. At approximately 14,800 pounds, the VK45 reflects the substantial, production-capable build quality that characterized Hitachi Seiki's approach to VMC engineering. The machine is well-suited to general-purpose precision machining in aerospace, automotive, and industrial component manufacturing.
