Flat mask machine The ultrasonic planar mask machine uses ultrasonic welding. When the mask is moved to the processing position, ultrasonic waves are automatically generated, which form micro-amplitude high-frequency vibration on the earband, which is instantly converted into heat, welding the material to be processed, and finally making the earband Permanently pasting or embedding inside the mask...

  Compared with traditional two-fluid spraying, ultrasonic spraying has the advantages of high coating uniformity, high raw material utilization, high coating thickness control accuracy, thinner coating thickness, less splash, no clogging of nozzles, and low maintenance costs. Compared with vacuum evaporation, CVD and other coating processes, ultrasonic spraying is a more economical thin film...

In ultrasonic turning, the high-frequency electrical oscillations generated by the generator (the frequency is generally 16 to 25 kHz, and the welding frequency can be higher) are applied to the ultrasonic transducer (see picture) to convert the high-frequency electrical oscillations into ultrasonic vibrations. Ultrasonic vibration uses a horn to amplify the amplitude (double amplitude is 20 to 80...

UM effectively machines precise features in hard, brittle materials such as glass, engineered ceramics, CVD SiC, quartz, single crystal materials, PCD, ferrite, graphite, glassy carbon, composites and piezoceramics. A nearly limitless number of feature shapes-including round, square and odd-shaped thru-holes and cavities of varying depths, as well as OD-ID features-can be machined with high qualit...

  In the UM process, a low-frequency electrical signal is applied to a transducer, which converts the electrical energy into high-frequency (~20 KHz) mechanical vibration (see Figure 2). This mechanical energy is transmitted to a horn and tool assembly and results in a unidirectional vibration of the tool at the ultrasonic frequency with a known amplitude. The standard amplitude of vibration ...
