Inventor: WATANABE AKIRA
IPC: B24B53/053
Filed: 2021-03-18
Abstract: To provide a grinding wheel modifying device and method capable of suppressing the occurrence of chatter shape on a circumferential face of a grinding wheel.SOLUTION: A grinding wheel modifying device 10 includes a modification tool T which is supported so as to permit rotative driving and is relatively moved in a rotative axis direction of a grinding wheel G which is rotatively driven and, thereby, modifies a circumferential face of the grinding wheel, and a control device CR which controls rotational frequency of the grinding wheel and controls relative movement of the modifying tool and the grinding wheel. The control device relatively moves the modifying tool and the grinding wheel while changing the rotational frequency of the grinding wheel and, thereby, performs rough modification of the circumferential face of the grinding wheel by means of the modifying tool. Further, the control device relatively moves the modifying tool and the grinding wheel while keeping rotative frequency of the grinding wheel constant and, thereby, performs precise modification of the circumferential face of the grinding wheel with the modifying tool.SELECTED DRAWING: Figure 3
