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

Introduction to Five Misunderstandings of Car Washing in Summer

When it comes to car washing, many people's ** reaction is, who can't do it! Indeed, car washing is a trivial matter, without much technical content. But what I want to say is that there are still many details that need to be paid attention to when washing a car. If you don’t pay attention to it, it may damage the car. Next, let’s talk about some misunderstandings that need to be avoided when washing a car in summer.

◆Washing powder car wash

Damaged car index: ★★★★★

** One misunderstanding that needs to be avoided is the choice of detergent. Many car owners will not buy professional car cleaners when washing their cars, but choose to use daily cleaning supplies instead. In fact, this is a very bad habit. Because the pH of these daily cleaning products is different, they are very corrosive to the paint surface of the car.

◆Directly spray with high pressure water gun/wipe with cloth

Damaged car index: ★★★★★

Many car owners wash their cars. The first step will choose to wash the car with a high-pressure water gun, and then slowly scrub. In fact, this is also a misunderstanding of car washing. Because, after a period of driving, dust or small particles will adhere to the surface of the car. If, before washing the car, you don’t need to rinse these off with clean water, but directly spray it with a high-pressure water gun or wipe it with a rag, these dust particles will make a “friction movement” on the paint surface of the car, damaging the paint surface of the car body.

◆Car washing in strong sunlight

Damaged car index: ★★★★

The reason why you don't wash your car under the scorching sun is because after the car has been exposed to the sun, splashing cold water on it will damage the body paint. Moreover, when the car is washed under the scorching sun, the water droplets on the car will form a convex lens effect, causing the upper layer of the car paint to produce a local high temperature phenomenon. Over time, the car paint will lose its luster. Therefore, the summer car wash must choose to be shaded or the sun is not big in the morning and evening.

◆No car washing in rainy season

Damaged car index: ★★★★

In the rainy season, many car owners are reluctant to wash their cars, thinking that the rain has washed their cars clean and there is no need to wash them again. In fact, these ideas are all wrong. Because rain water is acidic, if the car is not washed as soon as possible, the light rain will corrode the paint surface and even the car chassis will cause vehicle failure.

◆Frequent car wash

Damaged car index: ★★★★

It's no good to do more than anything, and the same is true for car washes. If the car is washed too frequently, it will greatly accelerate the oxidation of the paint surface, which will cause the paint surface to be dull and lose its luster. For the car wash cycle, it is generally appropriate to choose to wash it once a week.
