Recently, Merrill Tool & Machine made a significant expansion to its parts machining capabilities when it installed Mazak Versatech V-140N milling machine. The five-axis, double column unit is described as the largest machine of its kind in the United States, and true to that description it arrived at the Michigan shop on 19 semi trucks — and required a week to unload.

Merrill Tool & Machine is a 120,000-sq.ft. operating unit of the Merrill Technologies Group, in Merrill, Mich., that supplies manufacturers in defense, aviation, heavy equipment, energy, and machine tool markets.

The Group designs and produces complex fabrications, machines components, and assembles “mission-critical” aviation and defense equipment, and special-purpose manufacturing systems.

Mazak describes its V-140N as a “multiple-surface, five-axis double-column machining center,” designed for productivity at machining very large workpieces thanks to a spindle head that can shift between vertical and horizontal positions, or any angle in between.

“The machining time for cast iron and nonferrous material workpieces can be considerably reduced thanks to the fastest cutting feedrate and spindle speed in this machining center class,” the builder noted

The Versatech series machines feature 50-hp, 10,000-rpm spindles for multi-face machining. Their C-axis rotation is continuous, thus assuring full five-axis machining.

The standard control package is Mazak’s Mazatrol Matrix platform.
