Ultrasonic drilling machine: Ultrasonic drilling is a method that uses the ultrasonic vibration of the end face of the drill bit to drill the glass through the abrasive suspension.
Ultrasonic transducer is a device that converts electrical energy into mechanical energy (ultrasound). Among them, the most mature and reliable device is the piezoelectric effect to realize the mutual conversion of electrical energy and sound energy, which is called piezoelectric transducer.
