Mazak VC-Ez 16

The Mazak VC-Ez 16 is the smallest of the VC-Ez vertical machining centers compared here, with 30 in (762 mm) of X travel, 16.14 in (410 mm) of Y and 20.08 in (510 mm) of Z. It carries a CAT No.40 spindle that runs to 12,000 rpm, a spindle motor with a five-minute rating of 18 kW (25 HP), and a 30-tool magazine.

Its proportions are worth a look before any fixturing is planned. The table measures 37.4 in (950 mm) × 14.17 in (360 mm), so it is longer than the X travel and narrower than the Y travel. The spindle can pass the front and back edges of the table but cannot reach its ends. Vises in a single line fit naturally, while a fixture plate wider than 14.17 in (360 mm) will overhang. Z, at 20.08 in (510 mm), is longer than Y, which leaves headroom for tall workholding with a long drill above it.

The next size up is the VC-Ez 20, with 41.34 in (1,050 mm) of X, 20.08 in (510 mm) of Y and 25 in (635 mm) of Z on a 49.21 in (1,250 mm) × 19.37 in (492 mm) table. Taper, top speed and magazine size are the same on both, so the decision between them rests on envelope, not on cutting capability.

Mazak describes the VC-Ez series as a compact design focused on ease of use and maintainability, with Hybrid MX roller guideways on all linear axes. It also lists a thermally controlled spindle for the series. Mazak's table for this model gives no rapid traverse, table load, torque or machine weight, so ask for those before committing a heavy fixture or planning the installation.
