The purpose of the present invention is to easily change the swing point of a swing mechanism (10) of a centripetal swing grinder (1). To achieve the objective of the present invention, arms (15a, 15b) are supported by first swing shafts (12a, 12b) attached to supporting members (11a, 11b) to be rotated, and a swing body (20) is supported by second swing shafts (17a, 17b) attached to arms (15a, 15b) to be rotated. If the first swing shaft (12a) is fixed to the supporting member (11a) by a first connection part (24), a swing point of a swing mechanism (10) is a second swing center line (17c). If the second swing shaft (15a) is fixed to the arm (15a) by a second connection part (27), a swing point of the swing mechanism (10) is switched to a first swing center line (12c). |
