Piezoelectric crystal materials such as lithium tantalate and lithium niobate. Products are widely used in wearable terminals, wireless mobile communications, aerospace and other fields of surface acoustic wave devices, microwave technology for Q-switching, radio and television modulation, frequency doubling, optical parametric oscillation.

In the cutting of lithium tantalate and lithium niobate, mortar is still used traditionally in the industry. We have completed the verification of 80um WEDM, thus replacing the traditional mortar slicing and further optimizing the cost.
