Hard and brittle materials such as glass, ceramics, and hard alloys are difficult to process by conventional methods. However, if high-frequency vibration is added during the traditional milling, drilling, and grinding processes, that is, c....
Steel-bonded cemented carbide is a bonded phase of tool steel or alloy steel. The refractory metal carbide (mainly WC, TiC) is prepared as a hard phase by powder metallurgy. Its structural feature is that the fine hard phase grains are disp....
Magnesium powder is easy to burn and can cause an explosion when suspended in the air. All possible measures should be taken to ensure the correct collection and disposal of magnesium grinding dust. In the dry grinding of magnesium alloy pa....
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....
Definition of cold extrusion: extrusion at a temperature below the recovery temperature. For most non-ferrous metals such as aluminum, copper, titanium, and steel materials, it generally refers to extrusion at room temperature. Cold extrusi....
The traditional method of threading is mainly to use a forming tool or a grinding tool to machine a thread on a workpiece. There are mainly turning, milling, tapping, wire grinding, grinding and cyclone cutting. When turning, milling and gr....
The roller is the main part on the rolling mill. In the actual use process, due to a certain impact force, and the surface will be rubbed by high-speed, high-temperature red steel. The surface is required to have good wear resistance, and a....
Ultra-hard turning is defined as the machining process for turning workpieces with high hardness materials above HRC45. Generally, the hardness of the workpiece material can reach the range of HRC 58-68, and the material of the cutting tool ....
Typically said processing hardness exceeds 56HRC, or strength exceeds Rm steel materials 2000N / mm2 for hard machining. In most cases, the mold or forging die is subjected to carburizing or quenching after pre-machining. After pre-machining....
For a titanium alloy part, a machining example of a deep groove with a width of 4 mm, a depth of 30 mm, and a length of 300 mm is processed (Fig. 1). Titanium alloy has a small elastic modulus and a small thermal conductivity coefficient, w....
