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

Carry out the localization of imported auto parts

Imported auto parts have a large number of models, varieties, and high requirements. In the early stage of production, the investment in mechanical equipment, tool clamps, etc. is relatively large, and the requirements for raw materials are also relatively high. Therefore, the production cost is relatively higher than that of domestically-made auto parts, and in addition to the small batch size, the efficiency of its output is low. In terms of sales price, compared with imported originals, domestically produced parts are only about 30-50% of imported originals, and the profit of production enterprises is relatively thin. In order to smoothly carry out the localization of imported auto parts, the state should treat the designated units of the industry management department as export-earning enterprises, and implement preferential policies: first, it is necessary to supply high-quality and affordable raw materials to relieve production enterprises from looking for rice. For the future, relatively lower production costs will make production companies profitable. The second is to supply cheap coal and electricity to meet the supply of energy, especially the supply of electricity, so that production companies can avoid the suffering of lack of coal and electricity. The third is taxation. Implement tax reduction measures to encourage enterprises to produce imported auto parts made in China. Fourth, priority should be given to loans for working capital. Enterprises must be competitive. Due to the large variety of imported auto parts, small batches, and low output value, large and medium-sized production companies are not eye-catching, and small companies lack technology, equipment, and capital, and they want to do it but can’t do anything.

At present, most of the domestically produced imported auto parts are produced by small enterprises and township enterprises. This is because the quality of imported auto domestically produced parts is low, the production of long-term products exceeds sales, the short-term products are in short supply, and the key products with high technical content are not produced. The main reason. Therefore, it is hoped that large and medium-sized production enterprises will take the lead in thinking first, give full play to the role of backbone enterprises as the main force of the national industry, have the courage to shoulder heavy burdens for the localization of imported auto parts, and give full play to the advantages of mechanical equipment and technical strength; give full play to the imported technology And the role of a device to speed up the pace of absorption and digestion; to be far-sighted, do not fight for the gains and losses of the moment.
