During the working process, the machining head 11 can be adjusted at any angle within the range of 180 degrees (+ -90 degrees) on the XZ plane and 90 degrees (-20 degrees to +70 degrees) on the XY plane.
The X-axis drag chain 7 forms a U-shaped arrangement structure, the U-shaped opening of the U-shaped arrangement structure is located on one side facing the installation processing head 11, so that the bending part of the X-axis drag chain 7 is located on one side far away from the processing head 11, and the X-axis drag chain 7 cannot cause any influence on the processing head 11 when moving along with the cross beam 6.
