Drilling Technology of A588 Weathering Steel Plate

A588 weather-resistant steel plate is a special steel designed for corrosion resistance and weather resistance. Widely used in infrastructure and building structures such as bridges. The application of a588 weathering steel plate is more and more extensive. Many users who use 588 weathering steel plates also need to process them into shapes that can be used directly. A common processing method is drilling. How does the a588 weathering steel plate carry out the drilling process? let's see.

1. Select the appropriate drill bit according to the hardness of the material to be processed. For 588 weather-resistant steel plates with relatively low hardness, we can choose round high-speed steel drill bits and blunt-edged twist drill bits.

2. Correctly positioning the processed materials and mark the hole position. Before drilling, we must properly adjust the hole position. Generally, use the center punch or the electric marking pen to mark.

3. Drilling. The principle of drilling is to use the rotation of the drill bit to continuously hit and break the weathering steel plate. Select a low speed and continuously inject cooling liquid into the drill bit while drilling. The cooling liquid should be coolant or suds, which can prolong the service life of drill bit and ensure the quality of the hole. The injection speed cannot be too fast, so as not to easily cause the chip to wrap.

4. Reaming. If a large number of holes need to be processed, in order to increase efficiency, reaming is needed after drilling. Use a straight flute reamer to ream the holes slowly. The reaming speed should not be too fast, not exceeding 800r/min. Appropriate speed is helpful for chip removal.

5. Check the processed holes. After the weathering steel plate is processed, we should inspect the processing quality of the holes, to confirm whether the hole size is within the normal range and whether there are burrs and other defects.

The above is a brief introduction to the drilling process of a588 weather-resistant steel plate. In drilling operations, it is necessary to make targeted selections according to conditions such as materials and processing objects. Ensure proper functioning and high quality holes throughout the process.
