XY axis adopts mr55 European roller rail and z-axis hard rail design; XYZ three axes all use precision large-diameter guide screws and are properly tensioned; Z-axis adopts nitrogen counterweight design; Super large column and pillar box structure support, stable body structure, good overall rigidity, super heavy cutting ability, high precision, high power and high torque spindle. The design and processing of the full stroke and full support of the workbench will not produce deviation due to the suspension of the workbench; The y-axis stroke of all models is lengthened to ensure that the original design processing width can be achieved when using the side milling cutter; The side milling head interface is pre installed on the end face of all spindle castings, and automatic and semi-automatic side milling heads can be added.
