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 utility model belongs to the technical field of camera equipment, and particularly relates to an aluminum alloy casing of a camera. There are many types of camera housings: Infrared waterproof camera housing, Conch camera housing, Surve....
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....
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....
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 ....
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....
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....
In the process of machining titanium alloys, the following matters should be noted: 1. Due to the small elastic modulus of the titanium alloy, the clamping deformation and the deformation of the workpiece during processing are large, which....
