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
Electronic components Parts are the basic elements in electronic circuits, usually individual packages, and have two or more leads or metal contacts. Electronic components must be connected to each other to form an electronic circuit with specific functions, such as amplifiers, radio receivers, oscillators, etc. One of the common ways to connect electronic components is soldering to printed circuit boards. Electronic components may be individual packages (resistors, capacitors, inductors, transistors, diodes, etc.), or groups of various complexity, such as integrated circuits (operational amplifiers, exclusions, logic gates, etc.).

Component classification In order to maintain the stability of the operation of electronic components, they are usually covered and packaged with synthetic resin (Resin dispensing) to improve insulation and protection from environmental influences. [1] Components may be passive or active: Passive components are electronic components that do not have any gain or directionality when in use. In network analysis, they are called electrical elements. Active components are a kind of electronic components. Compared with passive components, they have gain or directionality when in use. They include semiconductor devices and vacuum tubes.

Active components belong to the execution protection function in the semiconductor category, as follows. Fuse-over current protection, can only be used once. Self-resetting fuse (PolySwitch, self-resetting fuse)-over current protection, can be used repeatedly after reset Metal oxide varistors, surge absorbers (MOV)-overvoltage protection, these are passive components, unlike TVS Inrush current limiter (Inrush current limiter)-to avoid damage caused by inrush current
