MITSUI SEIKI VJ7A VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a large working envelope with an 90.55" × 39.4" table capable of supporting workpieces up to 6,600 lbs, making it suitable for substantial production runs and complex multi-part setups. The machine is equipped with a #50 taper spindle with BIG PLUS capability, delivering up to 12,000 RPM standard with an optional 20,000 RPM configuration for high-speed finishing operations. With 25 HP at 30-minute rating, the spindle provides robust cutting power for both roughing and finishing applications across diverse materials. The three-axis configuration offers impressive travels of 78.8" (X), 49.2" (Y), and 19.68" (Z), with optional reduced X and Y travels of 59.05" and 39.3" respectively. Rapid traverse rates reach 787 IPM across all axes, enabling quick positioning and reduced cycle times. The 20-position automatic tool changer delivers tools in just 5 seconds, supporting rapid production workflows without manual intervention. Maximum feed rates of 197 IPM facilitate efficient material removal and precision finishing. This traveling column design with fixed table and traverse spindle system maximizes usable floor space while accommodating long workpieces, multiple-piece machining configurations, and versatile setups. The machine's combination of large capacity, high-speed spindle options, quick tool changing, and rapid traversal rates makes it ideal for job shops, production facilities, and contract manufacturers requiring flexibility across various part geometries and machining requirements.
