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....
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 annual output of a customers V-castings is more than 100,000 tons, and the casting molds are all wood molds. About 60 kinds of new products are developed each year. The products are mainly balanced and heavy, and the casting molds are la....
The overall processing of the impeller is carried out by forming a hub and a blade on a blank, instead of using a process in which the blade is formed and welded to the hub. The processing scheme is as follows: 1. In order to improve the st....
High-speed cutting theory is increasingly accepted with the development of CNC machining equipment and high-speed machining tool technology; High-speed cutting is a comprehensive concept, which involves many different areas of technology, i....
five axis milling machining ring thin-wall casing
High-performance aircraft engines employ a large number of integral, thin-walled complex structures and difficult-to-machine material parts. The use of a complex overall thin-walled structure reduces....
