An improved method and apparatus for grinding a rotary body, in which a rotatably supported grindstone is positioned in such manner that an extension of a rotary axis of the grindstone does not intersect a rotary axis of the rotary body and the rotary axis of the grindstone is inclined with respect to a plane perpendicular to the rotary axis of the rotary body to be ground. The rotary body to be ground is rotatably driven, and the grindstone is pressed against the outer circumferential surface of the rotary body to be ground in order that the outer circumferential surface of the rotary body to be ground can be ground by a relative slip produced at a contact point between the outer circumferential surface of the rotary body to be ground and the grindstone.

Method and apparatus for grinding a rotary body

A method and apparatus for grinding a roll in a rolling mill on an on-line grinding basis, are improved in that a freely rotatable grinding body such and is a grindstone is pressed against a surface of the roll to be ground as directed in the direction making a predetermined angle with respect to the axis of the roll. The roll is rotated so that the surface of the roll may be ground by a relative slip between the grinding body and the roll caused by their different circumferential velocities.
