1) Major infrastructure articles all adopt hi-rigid cast iron structure, which could ensure high rigidity, anti-bending and shock-absorbing performance; infrastructure articles adopts resin sand and experience aging treatment to make sure accuracy during the long-term operation, which provides guarantee for reliable environment. 2)X, Y and Z guide ways are made of hard rails without frictional resistance during non-feed motion or low-speed crawling phenomena, all of which are in favor of maintaining machine accuracy; 3) Feeding of X, Y and Z adopts famous ball screws of high-precision & high-rigid, which has high feeding speed and high positioning accuracy. 4) X, Y, Z axis with ball screws, all adopt closed shield; maintain clean ball screw & guideways, and make sure the accuracy of machine transmission and motion. 5) The machine tool adopts fully-closed structural design, much safe and reliable; user could choose semi-closed protective structure.
