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

Classification of CNC Machining Occupation Levels

1. Blue-collar layer:   That is, CNC machining operation technicians, proficient in machining and CNC machining process knowledge, proficient in the operation and manual programming of CNC machine tools (attributes: automated machine tools), understand automatic programming and simple maintenance of CNC machine tools (attributes: automated machine tools), such There is a large market demand for personnel, and they are suitable for operating workers of CNC machine tools (attributes: automated machine tools) in the workshop, but due to their single knowledge, their wages will not be much higher.   2. Gray collar layer:   One, CNC machining programmer:   Master the knowledge of 5 Axis CNC machining Aluminum   technology and the operation of CNC machine tools (attributes: automated machine tools), be familiar with the design and manufacturing expertise of complex molds (title: mother of industry), and be proficient in 3D CAD/CAM software, such as UG, GOOGLE PRO/E, etc. ; Familiar with CNC

Hydrostatic guideway of CNC machining lathe

The static pressure slide rail (TTW guide) of the CNC machining lathe transfers the oil with a certain pressure through the throttle to the oil cavity between the sliding surfaces of the slide rail (TTW guide) to form a pressure oil film to float the moving parts , Make the sliding rail (TTW guide) surface in a pure liquid friction state.   CNC machining General CNC machining usually refers to computer digital control precision machining, CNC machining lathe, CNC machining milling machine, CNC machining c17200   beryllium   copper   and milling machine, etc. The feed route of finishing is basically carried out along the part contour sequence. Therefore, the focus of determining the feed route is to determine the feed route of rough machining and idle stroke. In the numerical control processing, the control system issues instructions to make the tool perform various motions that meet the requirements, and the shape and size of the workpiece are expressed in the form of numbers and lette

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.
