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....
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....
Composite machining is the implementation of several different machining processes on one machine that is an advanced manufacturing technology. Turning and milling combined machining is the most difficult composite machining. It is equivale....
In the towed concrete pump truck, there is a typical large diameter thin walled part - the intermediate sleeve. The inner hole has a diameter of 202 mm, an outer diameter of 212 mm, and a wall thickness of only 5 mm. Moreover, the positiona....
For the work of turning long shafts, the technical content is relatively high and difficult, especially for the turning of the slender shaft. In the clamping method, if a more common method is used, the processing difficulty is increased, a....
The structural features of typical aircraft parts are thin-walled structures with complex shapes. The shape has a large change in the bevel angle, and the shape is mostly a hyperboloid, which requires precise forming. In order to reduce the....
The airfoil type blade has a wing-shaped section and a three-dimensional twisted space. It has a wide range of applications in axial flow turbo compressors, and its manufacturing has been generally carried out using a five-coordinate linkage....
According to the overall technical idea of the curved surface of the blade, the milling of the curved surface of the blade should ensure that the geometrical position accuracy of the profile basically meets the design requirements. And it h....
