Description

Technical Field

[0001] The utility model relates to the field of grinding devices, and more specifically, to a steel pipe end face flattening device. Background Art

[0002] After the steel pipe is cut, cut marks will appear on the cutting end face, resulting in burrs on the cut marks. Therefore, it is necessary to use an end face flattening device (grinding equipment) to grind both ends of the steel pipe to reduce burrs or cut marks. The existing grinding devices generally need to clamp the steel pipe twice, and then grind both ends of the steel pipe. Multiple clamping and increased processes are likely to reduce the grinding efficiency of the steel pipe. For this reason, we have proposed a steel pipe end face flattening device.
