Working principle of slow wire processing

 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...

Hydrostatic guideway of CNC machining lathe

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 o...

In recent years, it has also been widely used on car radiators

 

Tube-belt copper car radiator car radiators are mostly copper and aluminum. Copper is a metal material with the best thermal conductivity and has excellent formability, brazing and corrosion resistance. It has been used for a long time. The most important material for automobile radiators, but copper resource issues and price issues have always been the main reasons for the application of copper radiators. Aluminum has been widely used in automobile radiators in recent years due to its advantages of light weight, low cost, and abundant resources. However, due to its complex process and poor corrosion resistance, it is only used in cars and other small engines. Automobile radiator cores have different structural types. At present, they are mainly tube-type, tube-belt, cell-type, and cell-type. Tube-core type, the experiment used is a tube-belt copper car radiator.

Oscillating flow heat pipes There are two basic structure types of oscillating flow heat pipes for automobile radiators: closed loop structure and open loop structure. Small pipe diameter and repeated bending of the hot and cold ends are the two basic conditions for forming an oscillating flow heat pipe. The oscillating flow heat pipe also has the following basic characteristics: no wick is needed; there can be multiple heating and cooling sections, and the adiabatic section is optional; no additional power is required, self-excited oscillation; surface tension is dominant, but gravity also affects Heat transfer performance; the self-oscillating working fluid transfers both latent heat and sensible heat at the same time. The oscillating flow heat pipe radiator adopts a copper tube with an outer diameter of 4mm and a wall thickness of 0.5mm, with an open loop structure. In order to prevent impurities or dirt from releasing non-condensable gas to damage the vacuum in the tube and hinder capillary action, the pipeline is cleaned in advance, degreasing and descaling, and then manually bent with a special elbow mold, and a vacuum pump is used to pre-pump the pipeline. Low vacuum, and then use diffusion pump to pump high vacuum, flush into the medium ethanol. The heating section of the heat pipe is placed in the water tank, and the heat dissipation section is outside the water tank. The heat pipe is brazed and welded to the partition plate, and the strength of the partition plate is strengthened by welding metal strips. In this way, the connection between the heat pipe and the water tank is not only well sealed, high temperature resistant, and high pressure bearing.
