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

The market for auto parts is becoming increasingly fierce


There will be unprecedented fierce competition in the domestic market for auto parts. In the face of this new change, the member factories of the “Automotive Federation” must actively prepare for the challenge. Make use of strengths and avoid weaknesses, and give full play to group advantages. In recent years, the member factories of the “Jin Auto Union” have gained a place in the auto parts industry market based on product quality, reputation and service attitude, and won the trust of the majority of users. However, some member factories are agricultural machinery system enterprises after all, and their product sales are affected. However, the agricultural machinery system has more than 200 agricultural machinery parts sales departments above the county level. In recent years, under the situation of reform and opening up, most of these sales departments have carried out the business of auto parts, and there are many sales departments dealing in auto parts. The business volume is still very large. The member factories should actively develop this potential market, make good use of the two annual agricultural machinery ordering meetings, and sign the contract for the supply of auto parts at the same time as the contract for agricultural machinery parts.

Capture market dynamics and seize key models. The current situation in the automobile market is different. Domestic-made diesel vehicles are popular because they have better power performance, low fuel prices and easier solutions. Especially in rural areas, people are willing to buy diesel vehicles, so the sales continue to be optimistic, so they are supporting diesel vehicles. Most of these diesel engine models are produced by agricultural machinery system manufacturers, and most of their supporting manufacturers are agricultural Supply repair parts. Therefore, we must seize this goal, work hard on these models, find a way, and conscientiously do a full-scale service in the production of supporting and social maintenance accessories and pre-sales, sales and after-sales.

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.
