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

Doppy oil and gas micro lubrication has obvious advantages

Oil-air lubrication is different from other traditional lubrication methods, and Doppel’s micro-air-air lubrication technology has obvious advantages.

Modular structure design, the number of lubrication points increases or decreases according to the actual situation.The amount of oil and gas can be supplied regularly and quantitatively, realizing on-demand supply and avoiding resource waste;

Oil-air lubrication can maintain the bearing position and friction position with continuous fresh lubricating oil input and reduce the temperature rise of the bearing. Tests have proved that at the same speed, the use of oil-air lubrication for spindle bearings of the same model and working conditions can reduce the temperature rise of the outer ring by 9℃~16℃ compared with oil mist lubrication. If the temperature rise of the bearing outer ring is kept the same, the oil-air lubrication is used Can increase bearing speed factor by more than 25%;

Oil-air lubrication has no or very little pollution to the environment.The compressed air is basically discharged through the bearing, which does not contain oil or contains very little oil, which is beneficial to the health of the operator;

Due to the continuous supply of fresh lubricating oil and the outflow of fresh air inside the bearing, it is difficult for foreign impurities to enter, and internal dirt is also easy to discharge, which can increase the service life of the bearing.

Oil-air lubrication is the continuous and accurate delivery of a small amount of lubricating oil to the electric spindle bearing, which has the advantages of energy saving and environmental protection, and extremely high reliability.

It can be seen that Peifeng Doppel Micro-Oil-air Lubrication not only has unique and professional technical advantages, but also conforms to the spirit of resource-saving, environment-friendly, reasonable lubrication, and high-efficiency that China is currently advocating, and has broad development prospects.
