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

Minimal lubrication for machining oil hole of automobile crankshaft

<strong>Minimum lubrication technology is</strong> a new lubrication technology that makes the machining process more effective, energy-saving and cleaner. It can greatly improve production efficiency and increase the life of cutting tools by 50% during the machining of crankshaft oil holes. Above and get a clean workshop environment. <strong>Minimum Lubrication</strong> technology is a lubrication method that uses compressed air as power to atomize trace lubricating oil into micron-level suspended oil particles and transport the suspended oil particles to the cutting area. It is completely different from the traditional spray lubrication method that uses a large amount of cutting fluid or cutting oil: only spray lubrication cooling is provided during the cutting process, then there is less lubricating oil left on the chips and the workpiece, and the residual lubrication of the spray method Compared to oil, it is very small. Production plants use <strong>micro lubrication technology</strong> to process crankshaft oil holes, which can achieve higher production efficiency and lead the development of micro lubrication technology to adapt to changes in market demand. <br /> <strong>Minimum lubrication</strong> technology can bring good economic and environmental benefits, because in crankshaft oil hole processing, only a small amount of lubricating oil is needed to achieve good lubrication effect. So that the factory can obtain considerable economic benefits after using the <strong>micro lubrication</strong> technology. The crankshaft machining center quickly transports the oil mist to the cutting area through the main shaft and the internal cold drill. The control system of the machine tool is connected with the <strong>minimal lubrication</strong> device, and the opening frequency of the ball valve and the inner hole of the drill are changed according to the requirements of the processing technology. The size of the channel can automatically adjust the delivery volume of the lubricating oil mist. Micro-lubrication</strong> technology applied to machining crankshaft oil holes has the following advantages:<br />
(1) The oil mist can penetrate into the friction point and play a good lubrication effect;<br />
(2) In deep hole machining, the compressed air flow rate can take away the cutting heat, and a large amount of cutting heat is taken away with the chips. <br />
(3) The oil consumption is low, and the cutting friction points always maintain an appropriate amount of reliable lubrication;<br />
(4) The product has small volume, low gas source consumption and simple operation;<br />
(5) Reduce the maintenance cost and operating cost of the machine tool. <br />
