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 better t
The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state. CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200 beryllium copper and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette
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 stress,
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.
