The first is to assemble a plane rotary table on the vertical processing table, and a single pendulum rotary head is installed on the Z axis (generally swinging left and right along the Y direction). The rotation axis is the C-axis and the Z-direction single pendulum axis B-axis.
The second type is a 3+2 five-axis machining center, whose structure is equipped with a two-axis rotary table in the original vertical, and the movement directions X, Y, and Z are linear axes. The two-axis rotary table is designed along the X direction, and the tilt axis and the rotation axis are the A and C axes. The rotary table is designed along the Y direction, and the tilt axis and the rotation axis are the B and C axes.
These two methods are suitable for machining parts such as impellers, molds, and complex pentahedrons.
The third is to assemble a double swing head on the gantry headstock. Either way, the X, Y, and Z axes are linear axes, and the rotary or space axes are A, B, and C axes.
The fourth structure is the cradle moving beam type five-axis machining center. This structure is more professional than the 3+2 five-axis machining center for processing impellers. It can be used as a mold, with high efficiency, good precision, high speed, and relatively expensive construction cost. , the movement directions X, Y, Z are linear axes, and the rotation axis and the tilt axis are similar to the 3+2 five-axis machining center as the A/C axis or the B/C axis.
All of the above models can realize five-axis five-linkage, but five-axis linkage is not a real five-axis machining center. Only with a CNC system with PTCP function is a real five-axis machining center.
