Mazak VC-Ez 16

The Mazak VC-Ez 16 is an entry-level 40-taper vertical machining center at the compact end of the VC-Ez range, aimed at job shops adding capacity for small and medium prismatic parts.

Travels are 30" in X, 16.14" in Y and 20.08" in Z, on a table measuring 37.4" × 14.17". The table is longer than the X stroke, which is worth planning around: you can bolt down more length than the cutter can reach. In practice that favors keeping the work centered and using the table ends for stops, tooling blocks and datum hardware rather than trying to fit additional parts out there. The 16.14" Y stroke is the tighter constraint and is what defines the machine's class — this is a single or twin vise machine, not a plate mill.

The spindle is a CAT No.40 taper turning to 12000 rpm with an 18 kW (25 HP) 5-minute rating. That pairing is more useful than an entry-level machine usually gets. 12000 rpm supplies the surface speed small-diameter carbide needs in aluminum, and 25 HP on the short-duty rating means the machine will take a genuine depth of cut in steel for the length of a roughing pass. The important qualifier is that it is a 5-minute rating rather than a continuous one, so sustained heavy removal in tool steel is outside what the spindle is rated to do all shift.

Tool capacity is 30, which is more than most machines in this envelope carry, and for high-mix low-volume work that number matters more than it appears to. Thirty pockets is usually enough to leave a standing set of drills, taps and end mills resident while still holding job-specific tooling, which removes a large part of the setup time between short runs.

Taken together, the VC-Ez 16 suits shops machining compact parts in aluminum, mild steel and stainless where floor space is limited, the tolerance requirements are ordinary shop tolerances, and the work does not need a large table or a heavier high-torque spindle. It is a straightforward machine bought for capacity rather than for capability at the edges.
