Machine tool features The main shafts all adopt wide-area high-torque spindle motors with outstanding advantages such as wide constant power range, large output torque, low noise, maintenance-free, high speed, and low failure rate. Cooperating with the high-rigidity integrated spindle unit, the heavy-duty cutting capability of the machine tool has been greatly improved, and the output torque of the spindle is twice that of ordinary models. The main structure of the machine adopts modularization, a strong and closed box structure design, with good overall rigidity and strong heavy-duty cutting capability X/Y axis heavy-duty roller linear guideway.
