The invention relates to a sawing machine with automatic cut-to-length control function. The sawing machine comprises a sawing machine workbench, a sawing machine support arm, a photoelectric encoder, a sawing machine feed frame, a guiding rule and a control circuit, wherein a workpiece to be detected is arranged on a roll of the sawing machine feed frame, the front end of the workpiece passes through the sawing machine support arm and is placed on the workbench; the guiding rule is arranged at the front end of the workpiece to be detected; an encoder bracket is fixed at the radial side of the workpiece on the workbench; the photoelectric encoder and a depended wheel are fixed on the cantilever at the front end of the encoder bracket; the photoelectric encoder and the depended wheel are coaxially arranged, and the depended wheel is arranged on the top end of the periphery of the workpiece to be detected. The cut-to-length device is controlled by a counter and detected by adopting the photoelectric encoder, and is assisted by the guiding rule, so that the cut-to-length accuracy of the sawing machine is greatly improved, the production efficiency is improved, and the rejection rate is reduced.
