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....
Material machinability is often measured by the cutting speed allowed for cutting a material with a certain tool durability. Usually T = 60 min, then vT is written as v60. If the v60 used for cutting carbon steel in cemented carbide turning....
The specifications of printed circuit boards are complex and there are many types of products. The most widely used epoxy resin-based composite material in printed circuit boards is a micro hole (a small hole with a diameter of 0.6 mm or les....
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....
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....
