In the general machining industry, similar to aluminum film gasket parts, a plurality of experts can say that the parts cannot be machined; experts propose that punch forming and die machining can be adopted, and the size of an inner hole and an outer circle of a product is ensured by a cutting edge of the die. But the sizes of the inner hole and the outer circle of the part are larger, and the punching forming has great difficulty. And after stamping, the part is not easy to take down from the stamping die, the part is seriously deformed after being taken down, the surface is easy to generate creases, and the rejection rate is high. Experts also propose that fine boring can be performed by using a boring machine. However, the boring machine processing industry has the problem that clamping cannot be carried out, and after the boring machine processing industry finishes processing, the surface of a part is always creased or scratched, so that the apparent mass cannot meet the design requirement.
The defect of punch forming is adopted, and the punch forming is suitable for processing small-sized parts. The outer circle is generally not greater than 100. But the sizes of the inner hole and the outer circle of the part are larger, and the punching forming has great difficulty. And after stamping, the part is not easy to take down from the stamping die, the part is seriously deformed after being taken down, the surface has creases, the product is directly scrapped, and the rejection rate is high.
The boring machine has the defects that the boring machine cannot clamp during machining, process holes are drilled in inner holes, pressing plates are used for pressing, scraps machined by the boring cutter cannot be prevented from scratching the surface of a product, and the boring machine is low in machining efficiency.
