The wire threaded sleeve is a new type of threaded fastener, which is divided into two types: ordinary steel threaded screw sleeve and locking type steel threaded screw sleeve. It is a spring-like internal and external thread concentric body....
Engine lathe The engine lathe, one of the oldest metal removal machines, has a number of useful and highly desirable attributes. Today these lathes are used primarily in small shops where smaller quantities rather than large production runs....
It is important to choose the correct CNC tool when programming. The general requirements for CNC tools are easy installation and adjustment, good rigidity, high precision and good durability. On this basis, comprehensive consideration of th....
Small elastic modulus titanium alloy, small thermal conductivity coefficient of temperature, is a typical difficult materials, especially more difficult when cutting deep grooves. Figure 1 shows an example of machining a deep groove with a w....
Carbide inserts have high hardness, high brittleness, poor thermal conductivity and high heat shrinkage. They should usually be sharpened with diamond grinding wheels. However, because diamond wheels are expensive and difficult to repair aft....
With the continuous development of science and technology, in order to meet the special requirements of the performance of machine parts, some new materials with high strength, high toughness and high wear resistance are emerging. However, t....
Round insert milling cutters are suitable for milling titanium because their leading angles can be varied as appropriate. As long as these milling cutters are equipped with special inserts and the correct cutting parameters are applied, sta....
The heat treatment process of titanium alloy processing tools is mostly periodic operation and is a collective operation. Therefore, there is a clear working limit in the heat treatment process. For example, quenching of a batch of parts may....
The cutting method of the swarfs breaker and the main cutting edge are commonly used in the external oblique types, parallel types, and internal oblique types (see Figure 10).....
The swarf formed during the cutting process will have a higher hardness and a significantly lower plasticity and toughness due to the relatively large plastic deformation. This phenomenon is called cold work hardening. After cold hardening, the swarf ....
