The MULTIPLEX W-300Y Multi-Tasking CNC turning center is the industry’s most productive in terms of DONE IN ONE® part processing capabilities. Mazak factory-supplied parts loading/unloading has been enhanced by approximately 20 percent and chip-to-chip times are shorter. The MULTIPLEX W-300Y is equipped with a rack-and-pinion type gantry loader as opposed to previous belt-driven design.

Designed for single-setup, mid- to high-volume production and continuous operations, the MULTIPLEX W-300Y incorporates dual spindles and dual turrets with milling tools and Y-axis capability. Since both spindles offer identical performance, part-processing flexibility is greatly increased, and full 360-degree clamping units are incorporated into the integral spindles to further increase C-axis indexing accuracy.


  • Dual-spindle/dual-turret with milling tools and Y-axis capability
