Abstract

PURPOSE: To grind the entire inner surface of a weld groove uniformly by making a grinding wheel copy a weld groove under a constant grinding pressure to grind the inner surface, and when it becomes impossible to move forward, by swivelling the grinding wheel to make it copy towards the bottom of the weld groove.
CONSTITUTION: While a grinding wheel 27 is pressed against the inner surface of a weld groove 36 by spring 30 to copy the surface, a copy control mechanism P is moved forward to the direction of the depth of the weld groove 36. When the grinding wheel 27 grinds to the bottom 36" of the groove, the forward movement of the copy control mechanism P becomes impossible and the drive of a straight feed driver 7 is stopped, while the hydraulic motor of a swivelling feed driver 14 is rotated forwardly to swivel the copy control mechanism P horizontally and make the grinding wheel 27 copy to the bottom direction of the weld groove 36. Next, when the swivelling of this mechanism P becomes impossible, this mechanism P is swivelled reversely to return the grinding wheel 27 to its position before the swivelling. By moving back this mechanism P in the direction of depth for a distance corresponding to the depth of the weld groove 36, the grinding wheel 27 is returned to its initial position.
