METHOD AND DEVICE FOR POLISHING INNER SURFACE OF PIPE

Document Type and Number:

Japanese Patent JP3711250

Kind Code:

B2

Abstract:

PROBLEM TO BE SOLVED: To provide a method and a device for efficiently polishing the inner surface of a small diameter pipe.
SOLUTION: A precipitation trap 7 and an abrasive container 4 are respectively connected to both sides of a pipe 1 to be polished, and pressure is applied, alternately changing the direction to reciprocate and force-feed an abrasive 2 mixed in a polishing fluid 3 into the pipe 1 to perform polishing. Rough polishing is performed by high-speed reciprocating motion, and finish polishing is performed by low-pressure reciprocating motion.
