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

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

Market technical analysis of auto parts industry

The state has begun to strengthen macro control over the quality of auto parts, which has promoted the continuous improvement of product quality. For example, in 1992, the Bureau of Technical Supervision issued the “Implementation Measures for the Regulations of the People’s Republic of China on Product Quality Certification”, which was hosted by China National Automobile Industry Corporation, including experts from scientific research units, quality inspection agencies, and production enterprises, and established the China Automotive Product Quality Certification Committee . On behalf of the country, the committee implements quality certification for automotive products, and issues certification certificates, certification certificates, and certification marks. The establishment of the committee has played a catalytic role in improving product quality and reputation, promoting technological progress, ensuring the interests of users and consumers, ensuring personal safety, protecting the ecological environment, saving energy, and promoting international trade. Today’s auto parts market also has worrying problems, mainly including the following points: Compared with the production of complete vehicles, the production of repair parts is lagging behind. Some auto manufacturers are busy assembling new cars and are not on the agenda for the production of repair parts.

Many parts of joint venture vehicles have to be imported from abroad with a large amount of foreign exchange, resulting in long shutdown dates for maintenance vehicles and high maintenance costs. The quality of some parts of the domestically produced joint venture cars is not as high as that of some cars. However, according to users’ reports, some parts of the domestically produced parts are easily damaged. This is mainly due to the introduction of new technologies for vehicle manufacturing since the 1980s, while the parts manufacturing industry introduced fewer new technologies and lacked the necessary support policies. Therefore, domestic auto parts cannot meet the needs of new joint venture vehicles in terms of quantity and quality. Maintenance needs. The macro-control of the parts production industry is weak. The factories that are unable to produce auto parts have no unified technical standards. There are two machine tools and one thatched cottage to produce auto parts. There are no drawings and standards. They are copied with real objects, and the parts produced are not inspected. Get the market to sell, causing counterfeit and inferior auto parts to be repeatedly banned.
