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

Talking about the Software Upgrade Work of Auto Repair Service

 

In recent years, the expansion of corporate organizations, the addition of auto repair shops to service stations, and the lack of functions; the increase in interlocking sales departments, and the frequent interruption of external network dial-up communications, resulting in business data errors; network virus attacks, operations are threatened , Hardware and software upgrades should be urgently carried out.

The main content of the software upgrade is to increase the operation interface and application software modules of the database system and the corresponding database and index files, and modify the structure of the original database. The Web server, mail server, and database server of the intranet network are connected to the Internet metropolitan area network through the Gigabit switch and optical fiber through the two-layer Gigabit switch and the firewall; and are connected to the intranet through the three-layer Gigabit switch and optical fiber through the firewall. After several 100M switches of the company are transferred to each user; at the same time, the internal telephone network of the enterprise is connected to the three-layer Gigabit switch through the VDSL switch.

1. Due to the increase of organizational structure and the expansion of business scope, new functional modules of database application software should be added, and more than 50 databases and 20 temporary databases should be maintained. For some databases, fields and index files should be added to adapt to the new modules. For needs and query requirements, modules such as planning, accounts receivable, accounts payable, inventory analysis, inventory reporting, taxation, auto repair factory settlement, etc., are added to the original basis.

2. The original auto parts database system has the following problems: First, the key word for the database query is the auto parts spare part number. Due to the large number of manufacturers, there is a one-to-one relationship between the same auto part number and the part name, but the same name and part number are one-to-many. This requires operators to learn more than 10,000 spare part numbers before they can work. Today, labor mobility is a problem.
