Abstract

PURPOSE:To enable to carry out the titled barking accurately and in a short time by a structure wherein guide rollers and auxiliary guide rollers are arranged on a long tool supporting casing, which travels while supporting an annular cutter set to the finished inner diameter of the pipe. CONSTITUTION:Firstly, the annular tool 2 fitted at the tip of the casing 1 is faced on the front end opening of the pipe A so as to coincide the axis center of the tool 2 with that of the pipe P set to a base D by means of the guide roller 3. Secondly, the tool 2 starts cutting the inside of the pipe P by rotating and advancing the casing 1 by means of a cutting force transmission shaft 13. When the tool 2 advances while cutting the inside of the pipe P, the auxiliary rollers 6 and 7 abut against the cut inside surface of the pipe P. The abutment of the auxiliary rollers 6 and 7 against the cut inside surface of the pipe P prevents the casing 1 from producing the deflection, which tends to become larger in proportion to the distance between the guide roller 3 and tool 2, by the cutting force and suppress the generation of curve in the travelling direction and realize the favorable inside surface roughness and inner diameter tolerance of the pipe P.
