Further, the first grating scale and the second grating scale are axial arranged along guide rail where it.
Further, the bi-motor is arranged in the both sides of its moving direction for driving guide rail.
Further, the kind of drive of Y-axis guide rail and the Z axis guide rail motion is high class gear rack-driving.
Further, the Z axis guide rail is connected with the main spindle box body moved axially along the Z axis guide rail.
Further, it is provided with the 3rd grating scale in the Z axis guide rail, the 3rd grating scale is along Z axis axial direction cloth
Put.
Further, the X-axis guide rail, Y-axis guide rail and Z axis guide rail are arranged vertically two-by-two.
Compared with prior art, five high axle gantry machining centers of transmitting accuracy provided by the utility model, by using
Dual-motors Driving Y-axis guide rail and Z axis guide rail, eliminate the gap between guide rail, it is ensured that transmitting accuracy；Simultaneously in X-axis guide rail and Y-axis
Grating scale is set on guide rail, by the displacement of moving parts on each guide rail of grating scale accurate feedback, processed at five axle gantry
When deviation occurs in central motion coordinate, it is adjusted in time, so, avoids the five axle gantry machining center coordinates of motion and occur partially
Difference, it is ensured that its precision transmitted.
