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

Ordering must ensure the normal supply of necessary consumables for auto parts

 

Develop a procurement system to strengthen the construction of a clean government. In terms of parts procurement, a series of rules and regulations have been formulated. When ordering, you must ensure the normal supply of consumables necessary for production; report the purchase plan for the next month at the end of the month, and sign the plan before purchasing. If you encounter missing parts, you must ask for approval before purchasing on the market; the buyer will buy it back The accessories should be checked and accepted in time, and the quality should be strictly controlled, and the unqualified products should be returned in time without prepayment.

Through these measures, the loopholes in ordering have basically been eliminated, and the phenomenon of separate division of labor and family division has been stopped. At the same time, we have also formulated corresponding measures for clean government, not allowing salesmen to ask for cards in business interactions, and must be clean and honest. Through more than two years of practice, it has been proved that these measures are practical and effective. Achieved very good results. Strictly control the quality. At present, the auto parts market is a mixed bag, the good and the steam are uneven, the supply exceeds the demand, and the counterfeit and inferior products flood the market. These products affect life span and accelerate consumption, or cause mechanical accidents and cause major losses in production. In this regard, we must practice “eyes and eyes”, reject counterfeit and inferior products thousands of miles away, and ensure our normal production.

Strengthen management modernization and keep up with the development trend. Technological progress is an important driving force for economic development. With the vigorous development of the auto industry, the rapid increase in car models and auto parts has greatly promoted the prosperity of the auto parts market. It is recognized in work practice that to manage auto parts well, modern management must be strengthened. We set out to work in this area, sent a special person out to learn from the experience, and learned advanced management methods by inviting in and going out.

The automotive parts and parts machining, PTJ Shop offers the highest degree of OEM service with a basis of 10+ years experience serving the automotive industry. Our automotive precision shop and experts deliver confidence. We have perfected the art of producing large component volumes with complete JIT reliability, backed by the quality and long-term reliability our customers expect.
