Hydraulic breakers are already an important part of hydraulic excavators. The power source of the hydraulic breaker is the pressure oil supplied by the pump station of the excavator or loader. The hydraulic breaker mainly consists of piston....
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....
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....
Early diamond turning is mainly used for processing non-ferrous metals such as uranium membered oxygen or an aluminum alloy. Its main products are mirrors in various optical systems, such as the main mirror of radio telescopes, mirrors in L....
Unlike traditional concepts, it is not difficult to machine a quench-hardened workpiece to 5 m with the right machine tool and the right tool. Currently, tool suppliers have developed new tools that can withstand such machining conditions.....
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....
The processing of the positioning pin holes of the cylinder parts such as the cylinder block and the cylinder head has always been a key process. The remarkable feature of the box parts is that the process is complicated, and the processing....
During the machining process of engine and transmission parts, current process control measures cannot meet the hole machining requirements. The cause of failure is often caused by some failure modes of the machined hole. The distortion of....
By manually handling the burrs of the hydraulic valve, only the visible burrs on some surfaces can be removed, and the burrs cannot be completely removed. The best way to deburr the hydraulic valve cross hole now is thermal energy and elect....
