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

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

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

Inventory situation of auto parts marketing companies


Auto parts marketing companies have special and complex inventory, but the inventory of each kind of parts is generally only a single digit. This is mainly because the merchants are willing to reasonably expand the variety of accessories with limited funds, the easier the sales will be. But such a library poses a problem, that is, these stocks are very small and may be out of stock at any time. But in fact, the different distribution time may be a few days or a few months. Therefore, how to grasp the law of sales and reasonably control the species and quantity; if the variety, quantity, method and timing of the purchase are the same according to the sales and inventory conditions. An important issue that the auto parts marketing industry has been studying.

Computers are generally used to manage auto parts marketing companies. Computer management has been used to improve work efficiency, but has developed to a certain degree that its variety and diversification of marketing methods make it almost impossible to work with computers. Slightly large-scale companies have realized single-machine management; many large-scale public companies have established their own local area networks; some multi-stores are realizing long-distance communications over a distance of tens of kilometers (BAIC 99 is a means of information communication. In these two aspects In response to demand, information media for advertising in the auto parts marketing industry emerged, such as publications such as “Huicong Business Information” and “Dark Horse Auto Parts Business Information”.

These “business conditions” increase the transparency of the auto parts market and are also beneficial to auto parts users. Various means of transportation bring convenience for import and sales, whether it is the needs of customers, competition or complementary needs of merchants, they all constitute the demand for fast logistics methods. Therefore, in the current auto parts marketing industry, sea, land, and air transportation have been used in the purchase and sale of auto parts. And there is a corresponding service industry that connects merchants and transportation departments into a one-stop service system. Merchants can send the goods to the designated place or deliver the goods at the designated place to our company only by contacting them by phone.

For 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.
