Turning mechanism and early warning method thereof

The invention discloses a turning mechanism and an early warning method thereof, belongs to the technical field of machining, and aims to solve the problems that in the prior art, after a lathe tool is used for a long time, different degrees of abrasion occur, workers need to detect the lathe tool, the tool is prevented from being excessively abraded, the turning efficiency is affected, and the machining cost is lowered. In the prior art, the abrasion degree of a tool is detected basically in a manual detection mode, and the automatic early warning function cannot be achieved. Comprising a clamping chuck, a driving mechanism and a cutter installing mechanism, the driving mechanism is located below the cutter installing mechanism, the cutter installing mechanism corresponds to the circle center of the clamping chuck, the driving mechanism comprises a supporting plate and a rotating column, the supporting plate is located below the rotating column, the interior of the rotating column is hollow, a telescopic air
