ABSTRACT:
A sawing angle indicating device for a table sawing machine includes an angle sensing device composed of a sensing disk, a sensor unit and a circuit device. The sensing disk is firmly fitted on a driving connecting rod to rotate together for putting out signals to the sensor unit. Subsequently, the signals received by the sensor unit are put into the circuit device to be compared and checked to obtain an advancing or retreating datum, and then the signal is put out to the digital indicator on the circuit device. By so designing, the sawing angles of the table sawing machine can be read easily and accurately, able to elevate precision in processing.
