Claims

[Scope of utility model registration request]

A first eccentric cam vibrates a grinding wheel head side vibrating body equipped with a super-finishing whetstone, and a counterbalance side vibrating body is vibrated in an opposite phase to the grinding wheel head side vibrating body by a second eccentric cam having an opposite phase. In a super-finishing vibration device that balances vibrations while vibrating a super-finishing grindstone, the first and second eccentric cams are arranged in a phase in which the directions of vibration of the grinding wheel head-side vibrating body and the counterbalance-side vibrating body are reversed. , has a non-perfect circular shape that relatively reduces the acceleration of the vibration, and a cam follower bearing is provided between the first and second eccentric cams and the grinding wheel head side vibrating body and the counterbalance side vibrating body. A super-finishing vibrating device characterized by intervening.
