Slow wire walking, also called low-speed wire walking, is a kind of CNC machining machine tool that uses continuously moving fine metal wire as an electrode to pulse spark discharge on the workpiece to generate a high temperature of over 6000 degrees, ablate metal and cut into a workpiece. The principle of wire processing is the phenomenon that there is a gap between the wire electrode and the workpiece, and the metal is removed by continuous discharge. Since the slow-moving wire cutting machine adopts the method of wire electrode continuous feeding, that is, the wire electrode is processed during the movement, so even if the wire electrode is worn out, it can be continuously supplemented, so it can improve the machining accuracy of the parts and slow the wire. The surface roughness of the workpiece processed by the cutting machine can usually reach Ra=0.8μm and above, and the roundness error, linear error and dimensional error of the slow-moving wire cutting machine are much bett...
The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th...
KOVAR parts are commonly used as metal casing materials in the electronic packaging industry. Because they have a linear expansion coefficient close to that of molybdenum group glass, and can produce less sealing stress during the sealing (melting) process with molybdenum group glass, so To obtain good air-tightness, in order to make the metal tube and shell to achieve air-tight sealing, in the entire sealing process, the annealing process undoubtedly plays an important role as a link between the previous and the next. The internal stress generated during KOVAR machining also prepares the material structure for the implementation of the subsequent process-the sealing process of the metal parts. The main purpose of annealing Kovar shell before sealing is to: (1) Eliminate machining stress. When Kovar undergoes plastic machining deformation during cold working, about 10% to 15% of the applied energy is converted into internal energy, which is commonly referred to as internal stre...
The impeller with fan blades like a fan is an important source of power in industrial production equipment. The friction of the wind will generate force between its revolving blades, thereby providing a source of power for the production equipment. Then we should have some corresponding understanding of the precautions for impeller five-axis machining.
When using this equipment for processing, whether it is it or some other equipment, it should be closed in time after a long period of use to allow it to get adequate rest, because long-term work will make the equipment overheated and the parts of the equipment Cause different levels of loss. Overheated temperatures often make the stability of the equipment unbalanced, so we should pay special attention to this.
In addition to paying attention to whether the equipment is overheated and overloaded, it is also necessary to maintain and repair the equipment after a period of use. For example, because of the different materials of some impellers, the surface will be gradually rough or dull in day-to-day use. At this time, we need to perform regular maintenance of polishing and polishing on it, or use lubricating oil to it. Make its rough surface get a certain buffer. And we know that oil can form a protective film on the surface of the equipment to help the equipment isolate the moisture in the air, and prevent moisture from contacting the equipment to prevent rust. Sociologists say: “The use of tools is the fundamental difference between human wisdom and the wisdom of other animals, so we should pay attention to it” means that the use of tools is the fundamental difference between human wisdom and the wisdom of other animals. As said, we have used many tools in the production of our daily lives.
Impeller five-axis machining is undoubtedly our very powerful assistant in industrial production, so we must also learn to maintain and maintain it. Success or failure can often be seen in the details. When we notice these subtle matters that others have not paid attention to, we believe that this kind of wisdom will also radiate to other areas of life, making people feel that they have benefited a lot in production and life.
