The specifications of printed circuit boards are complex and there are many types of products. The most widely used epoxy resin-based composite material in printed circuit boards is a micro hole (a small hole with a diameter of 0.6 mm or les....
The machining quality of the crankshaft bore has a major impact on the performance of the engine. Chery Engine Division has continuously researched and continuously improved the finishing plan of the crankshaft hole of cast iron engine cyli....
The processing of the positioning pin holes of the cylinder parts such as the cylinder block and the cylinder head has always been a key process. The remarkable feature of the box parts is that the process is complicated, and the processing....
During the machining process of engine and transmission parts, current process control measures cannot meet the hole machining requirements. The cause of failure is often caused by some failure modes of the machined hole. The distortion of....
When developing the SD-95 type magnetoelectric speed odometer, it encountered a special problem of processing small blind square holes. The parts are shown in Figure 1. When the speed odometer is working, the meter and sensor are connected....
By manually handling the burrs of the hydraulic valve, only the visible burrs on some surfaces can be removed, and the burrs cannot be completely removed. The best way to deburr the hydraulic valve cross hole now is thermal energy and elect....
Since the cast iron cylinder liner is pre-cast in the blank. The rough and fine boring of cylinder bore is concentrated in the same process with some hole series processing, which makes it the bottleneck of the processing of all aluminum eng....
The processing of the valve block of the automatic transmission valve body of the automobile is the most demanding position in the entire machining process of the box hole. It is used in the processing of aluminum alloy valve bodies with a....
Due to the complicated structure of the engine and the high technical content, the manufacture of its components has always been the focus of attention. When the tappet hole of cylinder head is reamed, the short service life of the cutter ha....
A gasket is a mechanical seal between two objects that is typically used to protect the two objects from pressure, corrosion, and natural thermal expansion and contraction. Since the machined surface is not perfect, the gasket can be used t....
