5-Axis Gantry Mill. The GM-2-5AX is a cost-effective solution for simultaneous 5-axis machining and 3+2 machining of large parts, such as airframe components, layup molds, and composite structures. The flexibility of the 2-axis spindle head provides access to nearly any angle for complex machining. 5-AXIS GANTRY MILL.
The trunnion liner on the feed end of the mill may have a WORM to assist the ore into the mill. This worm acts like an auger or a screw. As the mill turns the spiral will pull the feed into the mill. Part of the feed chute will be a seal between itself and the mill. This seal is required to prevent spillage.
The head doesn't articulate. The trunnion style five-axis machine design permits the use of geared or belt-driven spindles that provide more torque at lower rpm. The stationary-head design also eliminates the possibility that the head will be pushed out of position while machining, which can occur on swivel-head machines during heavy cuts.
