<p>An apparatus for polishing the inner circumferential surface of the product (pipe) such as a pipe made from a stainless steel, which is used in a semiconductor pipe, food and drinks pipe and sanitary pipe, etc., is disclosed. An apparatus for polishing an inner circumferential surface of a pipe includes a base one end of which is changeable in an inclination with respect to the other end thereof. The pipe operation line that is installed on side of the base, fixes and rotates the pipe. The polishing operation line that is installed on the other side of the base, fixes and moves the polishing dipstick to be fitted into the inside of the pipe mounted on the pipe operation line. Under this configuration, the inner circumferential surface of the pipe made from a stainless steel, which is used in a semiconductor pipe, food and drinks pipe and sanitary pipe, etc., can be efficiently polished.</p> |
