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 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....
The blade curved surface finishing is to ensure that the curved surface roughness and waviness meet the design requirements. The material properties of the material are not changed, and the geometry and positional accuracy obtained by the m....
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....
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....
