Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Okuma. Configuration moves it a long way.

Overview

The Okuma MB-66V is a BT 40 vertical machining center with a 60.24 × 25.98 in table and a maximum machining volume of 59.06 × 25.98 × 25.9 in. Y travel is listed as 660 mm (26.0 in), which matches the table depth.

What marks this model is the number of spindle choices. The standard spindle runs 50-8,000 rpm with 15/10 hp. In square brackets, Okuma lists optional speed ranges of 50-15,000, 50-20,000, 50-25,000 and 50-35,000 rpm and optional power ratings of 30/25, 40/30, 20/15 and 20 hp. The page does not pair each power rating with a speed range, so the quotation has to name both. As a rule the highest-speed spindles carry the smaller motors, a point to settle early if the job needs torque as well as speed.

The magazine holds 20 tools as standard, with 32 or 48 as options. Rapid traverse is listed as 1,575/1,260 ipm; the MB-56V, the next size down, gives the same pair as X-Y and Z. The MB-56V has a 1,300 × 560 mm table and the same 15/10 hp standard spindle power, so moving up to the MB-66V buys table and travel, not a bigger base motor.
