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

How can lithium batteries enter the light electric vehicle market

How can lithium batteries enter the light electric vehicle market? The following measures can be considered. **, give full play to the characteristics of lithium batteries, design light electric vehicles with higher performance. For example, install batteries of the same quality to increase the capacity of the car (driving range, climbing ability, load capacity with a single charge). Second, design light electric vehicles with 1, 2, 3, and 4 people. Third, study to improve the quality of the car and reduce the standard. Fourth, strengthen sales measures to enable it to enter the countryside and go abroad. Fifth, let lithium battery electric vehicles enter the market as soon as possible and withstand the exercise of the market.

Statistics on the number of electric bicycles in China from 1998 to 2005 * The battery field also supported and promoted the development of electronic devices. Now, light-duty electric vehicles have been widely accepted, and lead-acid batteries have played a big role. In the past 7 years, the production and sales volume has nearly doubled every year. Lead-acid batteries have occupied the position of light electric vehicles at this stage with their mature technology and lower prices.

In this period, the research work of lithium-ion batteries must be continuously strengthened. In addition to improving the performance of lithium manganate and reducing its price, it is also necessary to study new battery materials and find new materials with larger capacity, longer life, and lower cost.

The    co-precipitation method is the best preparation method. The catalyst prepared by the combination of sodium hydroxide and urea precipitation has higher activity and thermal stability. The research results of using NHO to filter out the copper component in the catalyst show that the copper content in the catalyst has a best value, and Cu plays an important role in the formation of active sites of the catalyst.
