The processing steps of honing the rolling tube:
1. Material selection: Select the metal bar of suitable size as the raw material bar for processing the honing pipe;
2. blanking, free forging and heat treatment process: the raw material bar is processed by blanking, free forging and heat treatment;
3. Straightening: forging the raw material bar after processing;
4. Deep hole: the hole is made on the raw material bar to make the pipe;
5. Honing: honing the through hole of the pipe with honing oil stone, so that the through hole of the pipe meets the requirements of the size and processing precision required by the honing pipe;
6. Outer plane planing: The outer wall and end surface of the pipe are machined and planed by the lathe, so that the outer diameter of the pipe meets the requirements of the size and processing precision required by the honing pipe, and the honing pipe is completed. Honing is a relatively useful processing method for machining internal bores, which not only has high productivity but also high machining accuracy.
