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

How Do Cnc Swiss Machines Work

How Do Cnc Swiss Machines Work Save 0 What Is Swiss Machine –The full name of the walking CNC lathe, it can also be called the spindle box mobile CNC automatic lathe, the economical turning and milling compound machine tool or the slitting lathe. It belongs to precision machining equipment, which can complete compound  machining such as turning, milling, drilling, boring, tapping, and engraving at one time. It is mainly used for batch  machining of precision hardware and special-shaped shafts. This machine tool first originated in Germany and Switzerland. In the early stage, it was mainly used for precision machining of military equipment. With the continuous development and expansion of industrialization, due to the urgent needs of the market, it was gradually applied to the  machining of civilian products; the development of similar machine tools in Japan and South Korea Earlier than China, it was mainly used in the military industry in the early days. After the war, it was gradually

Spring Design Attention And Roll Forming Method

Spring Design Attention And Roll Forming Method The coiling characteristics and methods of springs are divided into cold coiling method and hot coiling method. Cold winding method: When the diameter of the spring wire is less than 8mm, the cold winding method is adopted. High-quality carbon spring steel wire is usually first cold drawn and then heat treated. After winding, it is generally not quenched, but only tempered at low temperature to eliminate the internal stress during winding. Hot-rolling method: Springs with larger diameter (>8mm) spring wire should use hot-rolling method. Hot rolled springs must be quenched and tempered at medium temperature. The Design Process Of Various Springs ·          Installation space: When designing a  compression spring , it is necessary to have a clear understanding of the space required for the installation of the spring, in order to effectively grasp the basic manufacturing conditions of the compression spring, including the outer diam

How to choose lubricating oil correctly

 

Lubricating oil is another big expense for car owners. To put it in exaggeration, lubricating oil is like human blood. The human body cannot do without blood for a moment, and the engine cannot do without lubricating oil for a moment. Cars basically need to change the lubricant every 5000-7500 kilometers.

As one of the most important protection products for automobiles, the selection of high-quality lubricating oil can effectively protect the engine, reduce wear and tear, and make the vehicle more economical.

For the lubricants used in cars, experts suggest: Only buy the right ones and not the expensive ones.

When choosing lubricants, many car owners believe that the higher the lubricant grade (label), the better, the brand-name, the better, and the more expensive the better. In fact, this is not necessary. The price of imported oil is 30% to 40% higher than that of domestically produced famous brands, and more than twice as expensive as ordinary domestically produced oils, so there is no need to blindly pursue famous brands at high prices.

Special reminder: The choice of lubricating oil should be selected according to the requirements of the engine. It is not necessary to use high-grade lubricating oil on engines with lower requirements, and it is not necessary to use lower-grade lubricating oils on engines with higher requirements. According to the technical requirements and conditions of use of the vehicle, it is necessary to “do what it takes”. For example, engine oil, for domestic cars, some domestically produced SJ grade engine oils can fully meet the requirements, and there is no need to buy imported ones.
