Further, first screw post 214 highly is less than the arc piece 211 height, and first screw post 214 highly is greater than the arc piece 211 height with second screw post 215 meshing back, and is concrete, sets up first screw post 214 highly is less than the arc piece 211 height, can ensure to take off long-edged milling cutter 110 after, face milling cutter 120 can normally work, sets up a screw post 214 highly is greater than the arc piece 211 height with second screw post 215 meshing back, can ensure that long-edged milling cutter 110 can be stable install on mounting bracket 200.

Further, the method also comprises the following specific operation steps:

s1: after the second threaded column 215 is fixedly connected with the first threaded column 214 through the bolt 230, the positioning fixture block 220 is used for uniformly positioning the face milling cutter 120 and the base 210, then the face milling cutter 120 is fixedly connected with the mounting frame 200 through the bolt 230, the top of the second threaded column 215 is meshed with the second threaded hole 115, then the second threaded column is meshed with the seventh threaded hole 217 through the bolt 230, the mounting frame 200 can be fixedly connected with the long-edge milling cutter 110, and then the vertically mounted block milling cutter 130 can be mounted on the first cutter mounting seat 113 and the second cutter mounting seat 123 through the bolt 230;

s2: the long-edge milling cutter 110, the face milling cutter 120 and the drill 300 can rotate by connecting rotating equipment at the rear part of the base 210, holes can be punched on the surface of the polaroid through the drill 300 at the moment, the holes can be reamed through the long-edge milling cutter 110, and meanwhile, the side wall of the polaroid can also be subjected to finish milling operation;

s3: when the finish milling operation is required to be carried out on the surface of the polaroid, the bolt 230 on the seventh threaded hole 217 can be removed, and the second threaded column 215 is separated from the first threaded column 214, at the same time, the long-edge milling cutter 110 and the drill 300 can be separated from the base 210, and then the finish milling operation can be carried out on the surface of the polaroid through the vertically-mounted block milling blade 130 on the surface milling cutter 120, in particular, because the surface milling cutter 120 adopts the vertically-mounted block milling blade 130 to carry out milling work, and the vertically-mounted block milling blades 130 are arranged according to radial and axial progressive fixed positions, when the rotating equipment rotates, the design of unequal tooth pitches ensures that each vertically-mounted block milling blade 130 only needs to cut off a small part of machining allowance in the radial and axial directions, and the semi-finish milling and the super-finish milling can be realized through single feed, thereby avoiding the phenomena that the workpiece is not in place, the allowance is large, the effect of poor surface machining effect is generated, and improving the machining precision, the surface roughness of the cutting blade can reach 0.06, and meanwhile, the abrasion can be greatly reduced because the working surface of the cutting blade 133 is large;

the using process of the invention is as follows: a person skilled in the art can fix the second threaded post 215 and the first threaded post 214 by the bolt 230, then uniformly position the face milling cutter 120 and the base 210 by the positioning fixture 220, then fix the face milling cutter 120 and the mounting bracket 200 by the bolt 230, mesh the top of the second threaded post 215 with the second threaded hole 115, mesh the mounting bracket 200 and the long-edge milling cutter 110 by the bolt 230 and the seventh threaded hole 217, then fix the end-mounted block milling cutter 130 on the first cutter mounting base 113 and the second cutter mounting base 123 by the bolt 230, connect the rotation device at the rear of the base 210 to rotate the long-edge milling cutter 110, the face milling cutter 120 and the drill 300, at this time, the drill 300 can punch holes on the surface of the polarizer, the long-edge milling cutter 110 can perform hole expanding operation on the punched holes, and also perform finish milling operation on the sidewall of the polarizer, when the finish milling operation is required to be performed on the surface of the polarizer, the bolt 230 on the seventh threaded hole 217 can be removed, the second threaded column 215 is separated from the first threaded column 214, at the moment, the long-edge milling cutter 110 and the drill 300 can be separated from the base 210, then, the finish milling operation can be performed on the surface of the polarizer through the vertically-installed block milling blade 130 on the surface milling cutter 120, and meanwhile, the single vertically-installed block milling blade 130 performs finish milling operation on the surface.

The above description is only a preferred embodiment of the present invention, and any person skilled in the art may modify the present invention or modify it into an equivalent technical solution by using the technical solution described above. Therefore, any simple modifications or equivalent substitutions made in accordance with the technical solution of the present invention are within the scope of the claims of the present invention.
