Abstract
PURPOSE:To perform high-efficient and accurate correction grinding of a worn rolling roll, by a method wherein, when the drive current value of a tool driving means satisfies a preset comparing condition, the step of a machining program is moved to the step of a next machining program. CONSTITUTION:A moving amount, in the direction of the radius of a rolling roll 2, of a rotary grinding stone 12 is preset as the current value of a grinding stone rotating motor 24. The set current value is compared with an output from a detecting circuit 26 to detect the current value of the grinding stone rotating motor 24. When the comparing result satisfies a comparing condition, execution of a machining program under execution is suspended, and the step of a next machining program is executed. Thus, during correction grinding of the rolling roll 2 formed in a complicated shape owing to a wearing state, only a part having low wear is high-efficiently ground, and a machining time can be sharply reduced.
