METHOD AND EQUIPMENT FOR TREATING INNER SURFACE OF DUCT, AND VACUUM DUCT

PURPOSE:To provide duct inner surface treatment equipment capable of surely removing an inner surface contamination layer or a deterioration layer becoming a gas releasing source of a long vacuum duct where mechanical machining on the inner surface is difficult.

Summary:PURPOSE:To provide duct inner surface treatment equipment capable of surely removing an inner surface contamination layer or a deterioration layer becoming a gas releasing source of a long vacuum duct where mechanical machining on the inner surface is difficult. CONSTITUTION:A broach 10 in which a cutting blade 11 having a chip breaker or a finishing blade 12 are formed in the outer circumference is moved in an axial direction on the inside of a duct to be treated with a rod 32 and a rod driver 34, and the inner surface of the duct 20 is cut in the axial direction to treat the inner surface. A surface contamination layer and deterioration layer formed on the inner surface of the duct 20 when the vacuum container duct 20 is formed from a raw material are surely removed over the axial direction of the inner surface of the duct 20. When the duct is used as a vacuum container, gas release caused by thermal separation and/or photo-stimulated separation by irradiation of emitted light is extremely reduced.
