The invention discloses an inner ring groove grinding and ultra-fine-processing integral machine for a fully automatic bearing ring. The inner ring groove grinding and ultra-fine-processing integral machine comprises a machine tool, wherein a grinding device, a groove grinding detection device and an ultra-fine-processing device are arranged on the machine tool. The problem of low efficiency of the existing inner ring groove forming is solved. The grinding device, the groove grinding detection device and the ultra-fine-processing device are installed together; the inner ring processing efficiency of the bearing ring is improved; meanwhile, the processing precision stability is high. A grinding wheel trimmer is added, so that the service life of the grinding and ultra-fine-processing integral machine is higher, and the precision is higher.
