Abstract
Installed in a band saw formed of a frequency converter, a motor, a driving wheel set and a band saw blade, a cutting speed display device is disclosed to include a modulator electrically connected to the frequency converter to output a linear modulation signal to the frequency converter for modulating the frequency of the output electrical power of the frequency converter so as to regulate the speed of the motor, and a display device that has a circuit device electrically connected to the modulator for receiving the linear modulation signal outputted by the modulator and converting the received linear modulation signal into a band saw blade cutting speed subject to one of a number of calculation modules set therein for enabling the band saw blade cutting speed to be displayed on the display panel. Thus, the cutting speed display device indicates the cutting speed of the band saw blade of the band saw in real time, and eliminates the problem of floating of the displayed data.
