Mitsui Seiki VL50 VERTICAL MACHINING CENTER

Technical Description

This vertical machining center features a 19.7" x 15.7" worktable capable of supporting workpieces up to 880 lbs, providing a robust platform for medium-load machining tasks. The spindle is vertically oriented with a high-speed HSK-E25 Big Plus taper, offering a maximum speed of 50,000 RPM and an optional HSK-E32 Big Plus taper variant with a 30,000 RPM top speed. It is powered by a 5.5 HP motor rated for 30 minutes, ensuring strong performance for various cutting operations. Tool management is handled by an automatic tool changer (ATC) with a capacity for 16 tools, enabling efficient and rapid tool switching to enhance productivity. The machine operates on a 3-axis system (X, Y, Z) with no U-axis, providing travel distances of 15.7" (X), 11.8" (Y), and 7.9" (Z). Each axis supports a maximum feed rate and rapid traverse speed of 1,575 inches per minute, allowing fast positioning and high-speed machining processes. The use of the BIG-PLUS spindle system ensures dual contact between taper and flange faces, promoting enhanced rigidity, accuracy, and repeatability during high-speed machining. This spindle design reduces runout and maintains consistent tool projection length, contributing to superior finishing quality. Overall, this machining center is designed for precision, speed, and versatility in vertical milling applications, making it suitable for tooling and production environments requiring high spindle speeds, rigid construction, and efficient tool handling.
