Huazheng Large Gantry Processing Center LM-2503B/LM-2204B/LM-2504B/LM-2704B/LM-2904B
Adopting a casting base, super large columns, and crossbeam box structure, the machine tool has strong rigidity and high stability. The crossbeam adopts an inclined back design, and the widened slide is subjected to wide force. The center of gravity of the machine head is evenly close to the center of the crossbeam to achieve better motion accuracy and chip cutting ability. Design a central symmetrical spindle system to ensure the configuration of the spindle, spindle motor, ball screw, and variable weight oil pressure cylinder position, avoiding temperature rise and displacement, resulting in imbalance and affecting machining accuracy. The Z-axis variable counterweight oil cylinder adopts a suspended support, which is close to the center of gravity of the movement, and symmetrically configures the spindle, driving screw, and spindle motor center to eliminate the generation of unbalanced force and ensure the machining accuracy of micro feed. Y-axis square rail type slide with full travel mobile support, with a maximum load-bearing capacity of 25000 kgf for motion stability.

Performance characteristics:
