    Precision Mill and Trim (PMT) System

    MAG’s Precision Mill and Trim (PMT) offers speed, accuracy and performance to manufacturers producing large parts from fiberglass, graphite composite, aluminum, and non-ferrous alloys. Whether applied to components for the aircraft, wind power, mold, pattern, watercraft, or automotive industries, the PMT provides high-performance in an affordable package. Built upon a rugged rail-type vertical gantry platform of standard modules, the PMT offers unlimited X-axis range, up to 60 m/min traverse speed, to perform precise 5-axis and 5-side maneuvering for milling, trimming, drilling and cutout operations.

    The PMT is a modular and highly configurable system to provide the right combination of features for most applications. Utilizing a rail-type gantry design, the machine’s X-axis range is virtually unlimited to handle extremely long parts or to permit multiple workzone part processing. As options, the Z-axis can be configured to provide 1, 1.5 and 2 m ram travel. The Y-axis cross rail can be configured to provide from 2 to 6 meters travel. The XYZ axes feature linear ways and AC servomotor rack-and-pinion drive systems. The two-axis spindle head provides 5-sided and 5-axis capabilities. A variety of workholding systems are available as option to meet specific application needs.
