GM Series Gantry Machining Center

1.Machine main parts: base, table, column beam, slider, ram are made of high-quality resin sand moldinq, high strength high quality cast iron, with perfect heat treatment process to eliminate residual stress. and layout enough reinforcement plate to guarantee the machine has the enough strength, rigidity and high stability.
2.XY axis imports overloaded roller quides, rigidity, excellent dynamic accuracy.
3.Triaxial transmission with double nut ball screw the Taiwan diameter grinding, compact structure smooth motion, high accuracy. The screw support Japan imported screw support bearings, pre-stretched at both ends, eliminating the thermal elongation caused by the loss of accuracy. Form a stable high rigid mechanical transmission system.
4.The bench structure beam, beam section, quide span, spindle center to guide surface distance is short, turning torque is small, good rigidity structure.
5.High rigid Taiwan gantry special spindle, the grease lubrication, can make the spindle bearing get constant and reliable lubrication, both economic and environmental protection to realize long-term free maintenance.
