Five-axis Machining

April 1, 2010

MAG’s MEGA 5 five-axis horizontal machining center has two spindle options for the high-torque machining of tough materials such as titanium or the high-speed processing of aluminum for large-part applications.

The machine combines twin ball screw-driven in X, Y, and Z axes; an infinitely contouring B-axis table; and a compact U-frame, A-axis tilt spindle with 180-degree sweep for full five-axis contouring of highly complex parts.

This enables five-sided machining, which eliminates the refixturing usually needed to reach odd angles and surfaces, improves part accuracy because of fewer handlings, and lowers the cost per part.

The XT spindle configuration was designed by MAG for machining hard metals such as compacted titanium, graphite iron, steel, and INCONEL® alloys and is offered in HSK100A and ANSI 50 versions. A dual-speed gearbox produces speeds up to 6,000 RPM, with constant power availability at 375 RPM for machining a variety of metals.

The AP spindle package, specially designed for machining aluminum, features a choice of two high-speed spindles – one rated for continuous operation at 67 HP and the other rated at 40 HP. Both have HSK63A tooling interfaces, 45 ft.-lbs. of torque, and can reach 24,000 RPM.

The MEGA 5 is built on a one-piece nodular cast-iron bed using a symmetrical design for high thermal and geometric stability. The machine’s T-layout moves the part to and from the spindle in a straight line for optimum boring position, and digital scales provide linear accuracy of 9 µm and repeatability of 6 µm.

With 56.1 in. of X-axis travel, 53.1 in. of Y-axis travel, and 49.8 in. of Z-axis travel, the machine can handle parts up to 51.2 in. diameter and 78.7 in. high.
