At present, most of common boring machines are three-shaft semi-digital display boring machines, and the boring machine is characterized by low machine cost and quick use. As shown in fig. 1, the three-axis + rotation mainly refers to: x-direction, Y-direction, Z-direction and horizontal rotation. Because the equipment is common equipment, the high-precision surface on a curved surface or a spherical surface cannot be machined, but the curved surface or a product which is not very regular inevitably appears in the actual production process, and a plurality of surfaces and holes cannot be machined or can be machined only by clamping for many times. Taking fig. 2 as an example, the processing of the surface a, the surface B and the surface C is easily realized on a five-surface machine tool, and the "fitting surface 1 for fitting with a tool" can be directly installed on a workbench, so that the mounting surface A, B, C can be completely processed once. The problem is that the horizontal boring machine has no way to complete the machining of all the surfaces by one-time installation because the main shaft is arranged on the side surface. The processing method of the ordinary boring machine shown in fig. 1 is that the processing can be realized by re-clamping and correcting one surface every time on the basis of adding a special tool on a workbench by utilizing 4-axis movement, and even more, dozens or hundreds of surfaces exist, so that dozens or hundreds of clamping and correcting are needed. When the workpiece to be machined is high in quality, the machining efficiency is low and the machining cost is high.
