[0002] Steel pipes are commonly used in industrial production and daily life, among which round steel pipes are used more frequently. Round steel pipes need to be polished during production to make their surface more shiny.

[0003] An existing round tube grinding device uses a pipe sleeve to fix the steel pipe during the round tube grinding work, and then uses a grinding wheel to grind the round tube at the notch of the pipe sleeve.
