Milling skills of A588 weathering steel plate

A588 weather-resistant steel plate is a low-alloy high-strength structural steel. Due to the addition of copper, chromium, nickel and other elements, the atmospheric corrosion resistance is increased. What makes this steel so special is its low alloy content and rich chemical composition.

Due to its distinctive features, A588 weathering steel plate is often used as a structural and architectural decorative material, such as decoration screens, corridors, bridges, etc. When manually milling A588 weathering steel plate, there are some skills that should be paid attention to.

1. Tool selection: When manually milling A588 weather-resistant steel plates, the choice of tools is particularly important. Try to use hard turning tools such as natural cobalt or cemented carbide. Due to the high surface hardness of the A588 weathering steel plate, low-speed and high-feed processing is required. For small milling machines, helical milling cutters should be used.

2. High speed: When processing A588 weathering steel plate with small milling machines, the cutting speed should be as high as possible, so as to improve the chip formation effect and obtain better surface quality.

3. Low feed: When manually milling A588 weathering steel plates, the feed rate should not be too high, otherwise it is easy to create large scratches on the surface of the workpiece. Therefore, the feed rate should be within the range of 0.02-0.1 mm/RR.

4. Cooling: Since the surface hardness of A588 weathering steel plate is relatively large, the cutting heat generated during the processing will easily lead to tool damage and blocking of the machined surface. Therefore, during the processing of the part, it is necessary to select a suitable cooling method, such as air cooling or emulsion cooling, to reduce the cutting heat.

5. Intermediate machining: During the processing of A588 weathering steel plate, when the tool is damaged after a certain number of cutting steps, it should be stopped in time and replace the tool. The average cutting amount of each step should not be too large, otherwise it is easy to break the tool. Therefore, in order to improve the machining efficiency, it is necessary to carry out intermediate machining, that is, small cutting once and often, so as to reduce the number of cutting times of each tool and extend its service life.

6. Grinding: After the manual milling of A588 weather-resistant steel plate is completed, it needs to be polished to improve its surface quality. Ordinary grinding discs and polishing discs can be used to remove burrs on the surface of parts and make their surfaces smooth.

The above are some necessary skills that should be paid attention to when manually milling the edge of A588 weathering steel plate. Under the premise of meeting the process requirements and processing accuracy, mastering the skills can improve the efficiency of processing A588 weathering steel plates and reduce processing costs.
