PROBLEM TO BE SOLVED: To accurately and easily align cores with each other of a plurality of shaft parts in a crankshaft. SOLUTION: This grinding device 100 includes: a first shutter mechanism 104 and a second shutter mechanism 106 including a first shutter 256 and a second shutter 294, which can be opened/closed, respectively, and a rotation mechanism 108 which holds the first shutter mechanism 104 and the second shutter mechanism 106 and rotates the first shutter mechanism 104 and the second shutter mechanism 106. A first weight part and a second weight part of the crankshaft are held by the closed first shutter 256 and second shutter 294 and, in this state, perform rotating operations following the rotating operations of the first shutter mechanism 104 and the second shutter mechanism 106. Grinding is performed by a grinding tool during the rotating operations. COPYRIGHT: (C)2012,JPO&INPIT |
