The utility model discloses a code disk of an electric tool rest of an economical numerical control machine tool, which is characterized by comprising a fixed disk, a turntable and a central shaft; The fixed disk and the rotary disk have inner holes, and the fixed disk also has fixed contacts arranged in pairs; The rotating disk has a pair of moving contacts corresponding to the fixed contacts; The central shaft passes through the inner holes of the fixed disk and the rotating disk, and is fixedly connected with the fixed disk and the rotating disk, so that the fixed disk and the rotating disk rotate relatively. The utility model provides an economical code wheel of an electric tool rest of a numerical control machine tool. The reliable contact of the code wheel contact is realized through a simple structure, which ensures that the code wheel contact will not be damaged after long-term use and can accompany the whole machine tool service cycle without replacement. The test shows that the service life of the encoder can reach 100W times and 10 years according to normal use. Moreover, because of its simple structure, it is not only convenient for production, but also low in cost and suitable for wide popularization.
