AI Technical Summary
In high-speed cutting, when the milling machine fixes the tool body by clamping, the centrifugal inertial force generated by the high speed of the tool causes radial displacement of the cutting teeth. The clamping mechanism is prone to failure, resulting in a high risk of the tool falling off.
The fastening mechanism includes a mounting post, mounting cylinder, retaining ring, threaded cylinder, and fixing components. The threaded connection and limiting components ensure that the tool body is firmly fixed on the milling machine, preventing the tool from falling off during high-speed rotation.
It improves the safety of the cutting tool when rotating at high speed, ensures that the tool body and cutting head will not fall off, and enhances the fixing effect.
