The invention relates to the field of tool abrasion detection, in particular to a wireless and intelligent tool abrasion detecting device based on acoustic emission signals. The wireless and intelligent tool abrasion detecting device comprises a numerical control milling machine, a milling cutter, a workpiece, an acoustic emission sensor, a main board, an embedded signal collecting module, an embedded signal transmitting module, a PC terminal with data processing and wireless receiving functions, and the like. According to the device, the features of the acoustic emission signals in the machining process are used as the researching object, and the single chip microcomputer technology and the wireless network technology are used as the methods, so that the acoustic emission signals are effectively transmitted to the PC terminal for data processing from a sensing device of the acoustic emission signals, and the tool abrasion state is detected. The wireless and intelligent tool abrasion detecting device is simpl
