Abstract

PURPOSE: To enable smooth cutting-off the differences in level and extraordinary projections made inside a pipe by making the cutting edge of a grinder project like a bow by the rotation of the shaft of the grinder.
CONSTITUTION: When a grinder 3 reaches an extraordinary place in a pipe 7 such as the difference in level (a) caused by the divergence of the pipe 7 and an inner- pipe projection (b), which is detected beforehand, an electromotor 41 is driven by a generator through the intermediary of an electric wire 6 by a method of remote control and the shaft 34 of the grinder 3 is rotated. With this rotation, a steel belt 32 provided with a diamond edge 31 thereon is rotated, while being made to project like a bow by the action of the centrifugal force, and the projection (b), the difference in level (a) and the like made inside the pipe are cut and removed by the diamond edge 31.
