Application of ATA-4052 High-Voltage Power Amplifier in the Field of Ultrasonic Processing

With the advancement of science and technology, the demand for high-precision components and complex microstructures has been continuously increasing, making ultra-precision machining technology a focal point in the industrial sector. Traditional machining processes often suffer from complex setups, low efficiency, and difficulties in meeting requirements for precision and geometric structural features. The innovative ultrasonic tool-tip trajectory machining process utilizes ultrasonic technology to set the tool-tip motion path, enabling the tool tip to undergo high-frequency reciprocating motion along a predetermined trajectory. Compared to conventional cutting techniques, this approach significantly reduces cutting losses while improving machining efficiency and precision.

The ATA-4000 series high-voltage power amplifier from Aigtek Electronics is widely used in ultrasonic processing applications. With a maximum output power of 547W and a -3dB bandwidth ranging from DC to 3MHz, it meets the requirements of most ultrasonic processing tasks.

Experiment Name: Research on Cutting with Variable Sharp Elliptical Vibration Trajectories

Experimental Principle: A high-voltage power amplifier is used to apply a high-frequency voltage to both ends of a piezoelectric transducer, generating high-frequency guided waves. These guided waves act on the cutting tool, causing the tool tip to vibrate at high frequency along a set trajectory, thereby completing the machining process.

Experimental Procedure:

A dual-channel signal generator outputs an excitation frequency of 96.8 kHz with an initial voltage of 3V. This signal is amplified by the power amplifier to an output voltage of 114Vpp. The voltage excites the piezoelectric transducer to generate high-frequency guided waves, which drive the tool holder to vibrate the tool tip along a predetermined high-frequency trajectory, achieving precise cutting.

Experimental Results:

After exciting the electromagnetic ultrasonic transducer, a time interval exists between the excitation pulse and the echo due to the separation between the excitation transducer and the piezoelectric sensor. Clear emission and echo peaks can be observed on the oscilloscope.
