The gasoline engine oil rail joint is used as an important part of an engine and plays a role in connecting a fuel oil pipe with an oil rail and a cylinder body, and if the part fails, for example: the running performance of the vehicle can be directly influenced by blockage and over-tolerance (small) of the diameter of the inner hole, and the phenomena of over-small oil pumping amount and incapability of acceleration occur if the oil pumping amount is small. Serious faults such as oil rail joint blockage, no oil pumping, abnormal ignition or running of a vehicle and the like can occur.
At present, oil rail joints in the industry are usually made of copper alloy metal materials, and have good cutting performance and heat dissipation performance. The oil rail joint is generally processed by the steps of cutting raw materials, heating, forging and pressing, and machining to finally form a finished product. Because the oil rail joint is a cylinder, a hole needs to be drilled in the center, the design standard of the aperture is 0.8mm-1.2mm, and the hole is formed by processing a drill bit on a numerical control lathe. Because the aperture is less, the drill bit often appears fracture or the sword phenomenon of collapsing in the course of working, and lathe continuation processing can lead to the oilhole to block up or the processing fault not in place, influences vehicle functionality.
