2000 HITACHI SEIKI VS50 VERTICAL MACHINING CENTER

Technical Description

The 2000 Hitachi Seiki VS50 is a 3-axis vertical machining center from Hitachi Seiki Co., Ltd. of Japan, representing a large-capacity platform in the VS-series line engineered for high-performance milling, drilling, boring, and tapping of medium-to-large workpieces. The VS50 offers an X-axis travel of approximately 39.3 to 40.1 inches, Y-axis travel of 20 inches, and Z-axis travel of 17.7 inches, served by a 44-inch by 20-inch T-slotted worktable suited to large and complex precision workpieces. The 30 HP spindle motor drives a CAT-40 taper spindle to a standard maximum of 10,000 RPM—with some configurations reaching 12,000 RPM—providing high-performance cutting capability across aluminum, steel, titanium, and aerospace alloys. The Seicos or Fanuc CNC control provides comprehensive G-code programming, rigid tapping, canned cycles, and the positioning accuracy characteristic of Hitachi Seiki's late-1990s manufacturing standards. Precision linear guideways and ballscrew drives on all three axes deliver the rapid traverse rates and positioning repeatability needed for high-throughput production. The automatic tool changer supports complex multi-tool programs in a single setup, and the robust cast-iron structure provides the rigidity and thermal stability required for tight-tolerance component manufacturing. The VS50 was one of Hitachi Seiki's most capable VMC offerings prior to the company's 2002 acquisition by Mori Seiki, reflecting the company's high engineering standards across large-format precision machining.
