The one piece bed and box type column castings are designed for rigidity and stability; even under the heaviest of cutting conditions. Fine grained Meehanite cast iron is used for its excellent strength, wear resistance and vibration dampening characteristics.
The table drive system is designed to provide ample cutting power for a wide variety of materials. Powered by large spindle motors, our high precision 2-speed gearboxes deliver massive torque values (up to 23,270 N-m of maximum torque) for heavy duty machining, even at low table speeds.
A thrust cylindrical roller bearing with a heavy duty taper roller bearing is used to achieve high axial and radial loads while yielding longer service life and higher accuracy. These bearings sit in a rigid one piece base casting, providing the ideal combination of increased table load and machining precision.
