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

Car maintenance: timely replacement of oil is very important

After a severe winter, the pace of spring is getting closer. Car owners at this time, in addition to checking for potential faults in their car, they should also pay special attention to the replacement and addition of oil. Let’s take a look at the editor of Liangchehui below!

1. Replace brake fluid

Some car owners often find that their car's brakes are soft after the end of the Spring Festival self-driving tour. The reason is that after the long-distance self-driving tour, the car's lubricating oil, coolant, and brake fluid loss is relatively large, but the car owner does not It is caused by timely replacement and addition. Therefore, in the spring after the weather has warmed up, car owners should check whether there is any shortage of these oils in their cars and replenish them in time.

In addition, when the brake fluid moves back and forth in the brake pipe, sludge and other impurities will be generated after a period of time, which directly affects the braking force of the vehicle. Therefore, the owner must replace the brake fluid every 20,000 to 40,000 kilometers.

2. Replace the dirty lubricating oil

After the Spring Festival, large-scale snowfall and icy roads across the country caused congestion. Vehicles on the way back and forth need to be started frequently. Engines often fail to warm up in time. Unevaporated water and insufficiently burned fuel will lubricate. The oil quality is degraded, which in turn leads to engine corrosion and sludge production, and the engine has been operating under high load.

Therefore, car owners can go to a professional store to check whether the lubricating oil is clean and flowing smoothly. In addition, low-temperature and high-load operation is prone to sludge and carbon deposits. If necessary, the lubricating oil should be replaced or the replacement interval should be reduced.

3. Replenish battery fluid

Battery* is afraid of low temperatures. The capacity of the battery in a low temperature environment is much lower than that at room temperature, and its performance will be significantly reduced. This is one of the reasons why the engine is difficult to start cold. Therefore, in the few heavy snow and low temperature weather after the Spring Festival, the owner of a liquid battery should replenish the electrolyte of the battery and adjust the specific gravity of the electrolyte. At the same time, the owner of the vehicle should clean the battery terminal and apply special grease to protect it, so as to ensure reliable starting and prolong the battery life.

If the car owner finds that some batteries have poor performance, it is best to replace them with new ones to ensure safe driving.

4. Check the coolant

With the advent of spring, as the temperature gradually rises, the coolant in the car’s water tank is insufficient. Many car owners will arbitrarily use clean water to replenish them when they find it. In fact, this method is unscientific. Clean water is easy to produce alkali and scale, and the boiling point is low, which is very easy to cause “boiling”. Therefore, even though the temperature has risen, car owners cannot change the coolant to clean water at will.
