A588 weathering steel plate is a steel plate that is resistant to corrosion and is made of chromium, copper, nickel and other elements. It has good corrosion resistance in air and is not easy to be corroded by acid and alkali. Its most important characteristic is its special meaning. It is a kind of special steel material. It has the advantages of large specific strength, good hydrogen stress cracking resistance, excellent atmospheric corrosion resistance and welding performance. The processing of A588 weathering steel plate is generally divided into two types, one is machining and the other is electrical spark processing technology.
The machining process of A588 weathering steel plate includes punching, shearing, planing, grinding, milling and drilling. The surface of the finished product has a poor smoothness and is not shiny, more in accordance with the characteristics of the surface of the material itself. The technological process of tool grinding and turning is commonly used. After processing, the surface of the A588 weathering steel plate has no obvious scratches, burrs and Burr.
The electrical spark processing technology of A588 weathering steel plate mainly includes EDM, EDM and EDM combined processing technology. It is characterized by fast production speed, high precision and good machining quality. It is suitable for processing complex shapes and for small details. In the process of electrical spark processing, the machining accuracy of A588 weathering steel plate can reach 0.015mm, and the surface finish Ra can reach 0.4μm. The current technology is generally used for EDM hollowing processing.
The molds of A588 weathering steel plate require high accuracy, and the precision of EDM hollowing reaches 0.001 mm. For example, k-Mold-making technology is adopted. K-mould adopts the method of single-side spark-electrode plus single-face EDM sinking polishing + single-side EDM sinking, which has high efficiency and meets the requirements of shape and size. This method has the advantages of high speed and high precision.
The processing parameters of electrical spark processing are a key factor in determining the machining accuracy and quality of A588 weathering steel plate. The control parameters include spark gap, discharge current, pulse width and discharge time, electrolyte concentration, dielectric fluid flow rate and temperature, nozzle pressure and distance, etc. the actual operation parameters shall be carefully selected according to the workpiece material, shape and size.
The electrical spark processing technology of A588 weathering steel plate has the characteristics of high precision, good surface finish and low production cost. It is an important method for surface processing of A588 weathering steel plate in modern industry. The application of electrical spark processing technology can improve the surface quality of parts and machining accuracy, reduce production cost and improve production efficiency.
