Embodiment 1
[0035] Such as figure 2 and Figure 5 As shown, a compound polishing method and device, firstly determine the initial polishing stiffness required by the polishing disc 1 according to the process parameters of the workpiece to be polished, and adjust the magnetic field of the ring electromagnet 2 through the shunt device 6 in the control box The strength makes the corresponding area of the polishing disc 1 reach the initial grinding stiffness, Figure 5 Center 1-1 is the corresponding initial rigidity area on the polishing disc 1. Then set the magnetic field intensity of equal gradient reduction in other areas of the annular electromagnet 2 of the circumferential array on the base 3, so that the corresponding areas of the grinding and polishing disc 1 present different stiffnesses, Figure 5Among them, 1-2 and 1-3 are the areas with different stiffnesses on the polishing plate 1, and the stiffness of the polishing plate 1 gradually decreases from the area 1-1 to the area ...
Embodiment 2
[0037] Such as figure 2 and Figure 6 As shown, a compound polishing method and device, compared with Embodiment 1, this embodiment makes four kinds of different magnetic field regions correspondingly distributed on the polishing disk 1 by adjusting the magnetic field strength of the ring electromagnet 2, and the polishing disk 1 Corresponding to four different rigidity areas 1-4, 1-5, 1-6, 1-7 respectively, 1-4 is the initial grinding rigidity area required by the grinding and polishing disc 1 determined according to the processed parts, 1-5, 1-6, 1-7 are the rigidity areas on the grinding and polishing disc 5 corresponding to the magnetic field with equal gradient reduction, then the rigidity of the grinding and polishing disc 1 from the area 1-4 to the area 1-5 to the area 1-6 to the area 1-7 slowing shrieking. Before work, the base 4 is fixed on the CNC machine tool, the workpiece 9 is fixed on the workpiece fixture 8, and the polishing spindle 7 is installed on the CNC...
