Abstract
The invention provides a mechanism for inhibiting grinding and cutting flutters, which mainly consists of a C-typed seat, a fixed support, a clamper and a vibration absorber. According to the vibration absorption principle in vibration theory, the clamper can move together with a mobile cutting tool in machining by connecting the clamper and the mobile cutting tool, and the strength of clamping an object to be machined by the clamper is controlled by an adjusting method, thus energy of excitation produced when the object to be machined is cut can penetrate the clamper and be transmitted to the vibration absorber and partly absorbed by the vibration absorber, thus the purpose of reducing the vibration at cutting points is realized.
