1987 OKUMA MC40VAE VERTICAL MACHINING CENTERS

Technical Description

The 1987 Okuma MC40VAE is a 3-axis vertical machining center from Okuma's MC series, representing the extended-capability variant of the MC40VA platform. The 'E' designation on the MC40VAE indicates an enhanced configuration relative to the base MC40VA, typically encompassing a higher-speed spindle or additional axis features, built on Okuma's rigid cast-iron column-and-base construction with Thermo-Friendly Concept (TFC) thermal compensation. The worktable measures approximately 39.37" x 16.14" (1,000 x 410 mm) with axis travels of approximately 30.09" in X, 16.14" in Y, and 17.72" in Z. The CAT40/BT40 taper spindle delivers approximately 7.5 HP continuous with a maximum speed of 6,000 RPM through a gear-head drive optimized for high-torque cutting in steel and cast iron. A 20-tool arm-type ATC provides standard tool change capability. The Okuma OSP-5020M control manages all three axes with servo drives and absolute encoders, providing G-code and conversational programming, canned cycles for drilling, tapping, and boring, and rigid tapping. Machine dimensions are approximately 87" x 75" (L x W) with a height of 105" and a weight of approximately 17,900 lbs. As an early-production unit from 1987, this machine should be carefully evaluated for electrical component condition, ballscrew wear, and control system integrity before returning to production service.
