The gantry frame of GMC1612 is constructed from high-grade Meehanite cast iron, stress-relieved and precision-machined to ensure long-term rigidity under heavy loads. All linear axes are equipped with oversized guideways and preloaded ballscrews, delivering repeatable accuracy even during extended multi-shift production. The high-torque spindle, supported by a rigid bearing configuration, maintains stability during deep cutting at high feed rates. For complex large-part applications, GMC1612 provides the machining envelope, thermal stability, and structural stiffness required for reliable, high-output operations.
