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 better t

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

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 of numbers and lette

A brief introduction to electric vehicle battery knowledge

 

When ordinary consumers still don’t know what electric cars are, electric car owners seem to have become fashion labels, or, in other words, a ruler of status and status.

This is certainly not the truth. The truth is that Tesla, as an innovative company, is also very good at marketing. Obviously, electric vehicles should not shut out ordinary people. Only when they are truly popularized and enter the homes of ordinary people can electric vehicles survive and develop. If it’s just for the self-entertainment of the rich and the noble, then the electric car can only become a toy for the rich.

Therefore, it is the responsibility of auto companies to produce electric cars that are affordable for ordinary consumers, not like Tesla. It is the responsibility of the media to popularize the knowledge of electric vehicles and enable ordinary consumers to fully understand the advantages and disadvantages of electric vehicles.

More than one hundred years ago, electric cars appeared earlier than internal combustion engine cars, and they have been quite successful for a while. However, Chinese consumers only started to understand it a few years ago. The country began to vigorously promote the development of new energy vehicles. Auto companies launched electric vehicle products one after another. Subsidy policies were gradually implemented, and the words electric vehicles slowly appeared in the newspapers. .

But just like the first electric car owner who won the lottery in Beijing, many consumers buy electric cars, to a large extent because they can't get the lottery on the petrol vehicles and they don't know much about electric cars. Some car owners can't install the charging pile for more than a month after buying the electric car because they have not understood the procedures required to install the charging pile in advance. Some consumers think that the huge battery pack in the car is an unsafe factor, and some consumers think that the electric car is probably the same as the battery car in the scenic spot, and it is completely inferior to the fuel car…

In fact, compared to fuel vehicles, electric vehicles have very obvious advantages. Zero emission, fast start, no electricity consumption in traffic jams, low cost of use, and relatively simple after-sales maintenance…Of course, electric vehicles also have obvious disadvantages, that is, charging and mileage are limited. If there is no fixed parking space at home, it is best not to buy an electric car. If you often run long distances, electric cars are obviously not suitable either.

For consumers, electric cars should be the second car in the family. It can be used to commute to and from work, and the mileage should not exceed 100 kilometers per day. There should be a fixed parking space at home to facilitate the installation of charging facilities. When driving, you just need to drive like a gasoline car. However, you should be careful not to scratch the battery pack at the bottom when passing through the Kuwa road.

There is no doubt that although electric cars were quite popular in the last century, it is still a new thing for us living in the 21st century. Understanding it, you will enter a whole new world, an electric life that has never been experienced before. If you reject it, you will lose some of the colors in your life, and you may not be able to keep up with the times. Therefore, no matter whether you have the conditions to own an electric car, when the electric car trend hits, please try to understand it and read it.
