All the gantries are quenched after heated at a high temperature to ensure that they cannot be deformed. The vertical gauge precision of the joints of the principal axis motor seat and the gantry is required to be within1 dmm, and the vertical processing precision to be within 5 dmm. The processing precision of the X/Y/Z axis is guaranteed to be within 5 dmm.
The precision of the rack square rail and the lead rail is within 1 dmm to ensure the processing precision of the Y axis and Z axis. The key to high precision of the rail slider and the rail depends on the good quality of rails and sliders in the early stage of installation. The precision of counterfeit products cannot be compared with that of quality products, even though broken accessories are timely removed and replaced, lowering the overall processing precision.
