They are mainly used as pipes for tap water supply systems in buildings, drainage, exhaust and sewage sanitary pipes, underground drainage pipe systems, rainwater pipes, and threading pipes for wire installation. The processed plastic pipes are cut by a pipe cutter to form fixed-length plastic pipe sections. Because the cutting surface of the plastic pipe by the pipe cutter is relatively rough, there are many burrs on the end face of the fixed-length plastic pipe section, which will affect the use of the plastic pipe section. Now, a grinder is generally used to grind the burrs on the end of the plastic pipe. The plastic pipe is rotated manually to make the circular grinding disc of the grinder for processing, but the circular grinding disc is not easy to clean the burrs on the inner wall of the end of the plastic pipe, and its work efficiency is low and the processing quality is poor.
