1988 MORI SEIKI MV40B VERTICAL MACHINING CENTER

Technical Description

The 1988 Mori Seiki MV40B is a 3-axis vertical machining center representing the first major production generation of the MV40 platform. The 'B' variant predates the later MV40E and retains the original, more compact work envelope, with axis travels of 31.5 inches in X, 16.1 inches in Y, and 20.1 inches in Z. The worktable measures 35.4 by 17.7 inches and is equipped with T-slot clamping for standard workholding fixtures. A CAT 40 spindle taper is driven by a 10 HP motor to a maximum speed of 8,000 RPM, reflecting the power levels standard for this era of VMC design. The machine is controlled by a Mori Seiki MF-M4 control—a Fanuc-based OEM build that provides standard G-code compatibility and reliable operator interfacing. Box-way construction on all three linear axes provides high rigidity and excellent vibration damping characteristics. The automatic tool changer enables multi-tool operations without manual intervention. Given the machine's vintage, buyers should assess the condition of servo drives, spindle bearings, and the CNC control, as components from late 1980s VMCs may have limited OEM replacement availability. Note: Mori Seiki merged with DMG to form DMG Mori around 2013; machines labeled MORI SEIKI are pre-rebranding era. The MV40B is well-suited for toolroom use and legacy production environments maintaining established machining programs.
