(FLORENCE, KENTUCKY) – In the long-standing tradition of Mazak using the latest Mazak machine-tool technology in its own manufacturing plants, Mazak’s Florence, Kentucky manufacturing plant will be showcasing the large, double-column VERSATECH V-140N Vertical Machining Center with a new headstock design and 122-by-392-inch table for machining large castings. This is part of Mazak’s ongoing mission of expanding manufacturing capacity and productivity in its own plants with the latest machine-tool technologies.

Where former VERSATECH models required a change of cutting heads to move from vertical to horizontal cutting, the new VERSATECH V-140N has a nutating spindle head, which means it can move in B and C rotary axes with minimum program increments of 0.0001 degrees. Since no head change is required, the new machine drastically cuts non-productive idle time and can produce contoured and five-faced parts in a single setup.

The headstock features a 50-Hp integral spindle motor with a 10,000-rpm top spindle speed and maximum torque of 253.7 ft.-lbs. It can accommodate heavy-duty cutting at low speeds and produce superior surface finishes in aluminum and other non-ferrous materials at high speeds.

With a Y-axis stroke of 181 inches, the VERSATECH V-140N can perform side-face machining with short-projection face mills along with side drilling and tapping up to 15.75 inches in depth with the spindle head in the horizontal position. Servo motors mounted directly to the ballscrew nuts in the X and Y axes along with linear guides in Z result in rapid-traverse rate of 1,181 inches per minute along with high-accuracy circular interpolation.

Tool magazines of up to 330 tools are available with a two-second tool-change time (tool-to-tool). Plans for the VERSATECH V-140N at the Mazak plant include machining large castings, including beds and columns for Mazak machine tools built in Kentucky.
