3-axis CNC milling machine GM-2

verticalgantryBT 40

The GM-2 is a heavy-duty 3-axis gantry mill designed for large-part machining, such as airframe components, large plates, and long extrusions. The machine’s rigid steel construction provides a very stable cutting platform, and a 1" thick aluminum table is standard. A traveling guard protects the operator from chips and coolant, and keeps the workspace clean. 75" between columns for large parts Rigid-steel construction Traveling guard for chip and coolant containment 1" thick aluminum table An evolution of our gantry router platform, the GM-2 Gantry Mill is a large-frame milling machine capable of serious metal removal. Below is a comparison of features that differentiate the GM-2 (gantry mill) from the GR-712 (gantry router). Gantry Mill Design Improvements: Improved Gantry Design Twin X-Axis Ballscrews GM/UMC Spindle Head Assembly Maximum Torque Increased Axis Thrust Higher Tool Changer Capacity More Z-Axis Travel Augers For Chip Removal Free-Standing Control Pendant Improved Gantry Design To allow the Gantry Mill to take much heavier cuts, we stiffened the X-axis considerably, and redesigned the columns of the gantry assembly to improve stability and rigidity. The forward-most X-axis linear guide trucks are now well in front of the bridge, moving the center of gravity back, so the X-axis trucks are more evenly loaded. Also, there are now four linear guide trucks per side, and each truck has a higher load rating than those on the gantry router series machines.
