Working principle of slow wire processing

by
 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 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

by
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

The use of trace oil and gas lubrication can increase the service life of the saw blade

cncmachining December 29, 2021

Compared with the traditional cutting fluid lubrication method, the sawing oil-air lubrication device has great advantages:

● The sawing machine no longer needs to add filtering facilities, which saves the initial investment.

●
There is no need to process the materials after oil-air lubrication, and you can directly enter the following types of work.

● The oil consumption of oil-air lubrication is very low, and the cost of lubricating oil is greatly reduced.

●
It will make the processing process clean and environmentally friendly, which is more conducive to the maintenance of the machine tool.

●
The surface of the workpiece is dry and can prevent rust without subsequent cleaning.

To increase the life of the saw blade, it is necessary to choose a more suitable lubrication method. The oil-air lubrication device has an undoubted effect in improving the lubrication effect and life of the saw blade. According to statistics, the oil-air lubrication greatly reduces the frequency of saw blade replacement in the use of sawing. The use of sawing oil-air lubrication saves maintenance costs, and the benefits it brings are far superior to the use of emulsion lubrication and cooling. Therefore, the use of sawing oil-air lubrication is undoubtedly an economical and reliable lubrication solution.

The sawing oil-air lubrication device is a consumable oil-air lubrication. In the lubrication method, the oil-air injection method is used to automatically apply a small amount of fine oil mixed with oil and gas to the saw blade. Because the amount of lubricant is small and it is directly sprayed on the edge of the saw blade, It can well lubricate the saw blade and is an economical and reliable lubrication method. The supply of lubricating oil is also usually intermittently supplied by the saw blade during the cutting process. There are two ways to adjust the amount of oil. One is to adjust the oil supply frequency and the pneumatic pulse generator to adjust the time interval. The second is to adjust the amount of oil supplied by a miniature lubrication pump.
