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,
Anyone who knows CNC equipment knows that the processing configurations used by CNC equipment for processing different types of products are different, that is to say, if you want to process more precise parts, you need to use communication equipment five-axis processing, but if the control is not good, it will affect the quality of the parts. In order to avoid this situation, it is necessary to pay attention to the following points when using five-axis machining.
1. Pay attention to strictly abide by personnel operating regulations
Table of Contents
Equipment such as five-axis processing is relatively dangerous during operation. Careless operation of personnel can lead to injuries. As long as the operation specifications are followed to avoid personal injury, such as wearing protective equipment as required, do not wear scarves , Gloves and leaders, women should also pull up their hair and wear hats, etc. Therefore, it is important to pay attention to strictly abide by the personnel operating regulations.
2. Pay attention to the trial run before processing
It is only the beginning to make the adjustment of tool compensation, machine zero point and workpiece zero point before starting up, and check the equipment protection, insurance, signal and position part, but more importantly, start the trial operation of the machine. Many people may think that it can be turned on directly after the inspection is completed. In fact, it is impossible to check the operating conditions of the lubrication, mechanical, electrical, hydraulic, digital display and other systems without trial operation. Therefore, the trial operation before processing is very important.
3. Pay attention to the parts inspection before starting up
The five-axis processing of reputable communication equipment needs to pay attention to the corresponding preparations before the equipment is turned on. For example, the inspection of important parts and items needs to be paid attention to, because many parts, switches, insurance and protection in the equipment are all It may be a hidden danger point for the equipment after operation. If we cannot do an inspection at the beginning, the bad consequences after opening it are unimaginable, so it is very important to do a good job of inspection before starting the machine.
In most cases, general Cnc Machine tools can process many common parts, but high-quality parts require five-axis machining such as CNC equipment. Therefore, if you want to make better parts, you must not only know where the five-axis machining of communication equipment is. It is sold, and you need to know what to focus on when using this five-axis machining.
