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

It is very important to replace the lubricating oil in winter car maintenance

  As the weather turns cooler, ordinary lubricating oils will become thicker at low temperatures, and their fluidity will be weakened, making it difficult to start the vehicle and increasing wear and tear.Therefore, car owners who use ordinary lubricating oil must not forget to change the oil in their car.
  General lubricants are**
  The lubricating oil should be selected according to the requirements of the engine. You can neither use too high-grade engine oil on engines with lower requirements, nor use lower-grade engine oil on engines with higher requirements.The choice of lubricating oil can be increased by one level on the basis of the manufacturer’s recommendation, or the performance of synthetic engine oil is better.
  In addition, motor oils for winter and summer are now available on the market.The general-purpose engine oil can maintain stable lubrication performance no matter how the temperature changes, and has a better protective effect on the engine.Therefore, this oil is the best choice.
  If the engine is new or in good condition, use low-viscosity oil as much as possible, such as 0W-40, 5W-40, and 10W-40, so as to make the lubricating oil flow faster and reduce the wear when starting.If it is in the high temperature season or the engine has worn to a certain degree, it is necessary to choose high-viscosity oil, such as 15W-50, etc., which is conducive to forming a thicker oil film, maintaining oil pressure, and reducing oil consumption.
  No need to add additives in lubricating oil
  Experts said that it is generally not recommended to add additives to lubricating oil.Because the lubricating oil itself is composed of base oil and additives, its formulation has been tested and screened.Adding additives may be counterproductive, not only reducing the original cleaning and anti-wear functions of the lubricating oil, but also increasing sludge and carbon deposits, affecting the performance and service life of the engine.
  Professionals remind that when replacing the lubricating oil, the lubricating oil filter element generally needs to be replaced, so that the newly replaced lubricating oil can perform better.Lubricant products of different brands cannot be mixed.
  There are tricks to distinguish good from bad
  At present, there are many fake products on the market. Many car owners can’t distinguish the quality of lubricating oil. Now I will teach you a few tricks. **To observe.If the oil is clear and yellowish-brown, it means its quality is good; if the color is turbid or emulsified, it means that it contains more water; if the oil has a burning smell, it means that it is prematurely oxidized or mixed with other oils.The second is to check if there is any sediment. It is definitely not a good oil.Third, you can drop the engine oil on the iron plate or exhaust pipe above 110°C. If there is a popping sound, it means that the engine oil contains moisture.
  In fact, the *insurance is to go to a designated dealer, a major brand gas station or a repair shop to purchase or change the oil.
