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

Micro-lubrication technology is used for the bearing bush of the deweighting and balancing machine

Balancing machines are widely used in modern machinery, and the choice of lubrication methods is also very important. Traditional lubrication methods generally use oil lubrication, but in the deweighting process, the chips are easy to fall and get stuck on the bearing bush, which affects the deweighting balance. Accuracy.
If the bearing bush of the balancer adopts micro-lubrication, it can effectively solve the problem that the chips are easy to fall and get stuck on the bearing bush and affect the accuracy of the balance of weight removal. It will also obtain many benefits: The use of micro-lubrication can reduce oil consumption and save energy. Environmentally friendly
The running cost of the micro-lubrication system is very low. Compressed air is the power source of the system, and the energy consumption is low; it can reduce the damage caused by chip jamming between the bearing bush and the journal when using oil lubrication;
It can provide good lubrication to the drill bit and prolong the service life of the cutting tool-the drill bit.Compared with traditional lubrication methods, there are many advantages of micro-lubrication. In order to ensure the effect of micro-lubrication, special attention should be paid to the following two points:
Dry and stable air source: The stability of the air source pressure is an important factor for the normal operation of the micro-lubrication device.The power source of the micro-lubrication device is compressed air, so the stability of the compressed air pressure is very important.The moisture in the compressed air will directly affect the atomization effect, and the lubrication effect will also be affected. Therefore, the stability of the air source pressure and the drying of the air source are very important.
2. The design of the oil mist output channel size of the bearing bush of the balancer is very important, and its rationality directly affects the lubrication effect of the bearing bush.For the design of the bearing bush, in practical applications, the design passage of the bearing bush does not need to be too large, and the corresponding calculation can generally be carried out according to the size of the journal.The micro-lubrication itself has a very small diameter at the lubrication terminal.If the passage is too large, the air supply will be insufficient and the oil mist output will be too large, resulting in an impact on the operating environment.Full attention should be paid to the design.
