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

Auto maintenance and auto parts market are closely linked

Illegal business During the repair process, some use inferior parts to pretend to be high-quality parts; some use inferior products to replace original high-quality parts; some disassemble and assemble parts of car A to car B of the same model, and collect parts updates from customers. Expenses; some use damaged parts, dismantled old parts to pass off as qualified products, etc., which has seriously damaged the image and social reputation of the auto repair market. For example, in January this year, an auto repair shop promised to replace a new body when it was repairing a car for a company, but the actual replacement was the body after the accident, deceiving users. All technical supervision and quality inspection institutes and stations, during quality supervision or quality follow-up inspection, if any violation of the above regulations is found, they shall be stopped immediately and reported at the same time.

The quality of the maintenance team is low. Vehicle maintenance requires high professionalism and skills, and has a large dependence on inspection and maintenance equipment. The characteristic of opening a business with a large number of one-time investment. In some developed countries abroad, once a car is repaired with quality problems or using inferior parts to cause an injury, the repair manufacturer will be caught in a lawsuit for high compensation and it is difficult to get out. As the nationwide pilot program for the professional market has just started in China, the legal system has yet to be improved. Some social organizations and even individuals who do not have sufficient conditions and capabilities hire repairers privately. Due to the low quality of the personnel, there is a serious lack of basic guarantees for the quality of repairs. If the distribution unit continues to sell products that are unqualified in random inspections and have not been re-examined (reported for inspection) for rectification, they shall be re-examined and punished once they are found. Low quality of auto parts. With the development of society and economy, the auto parts market has become an important emerging industry. According to incomplete statistics, there are about 40 auto parts stores in our city, and they are still growing. At the same time, the contradiction of many problems in the product quality of the auto parts market has become increasingly prominent. It is worth noting that car maintenance and auto parts market are closely linked.

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.
