Tool unit applied to ultrasonic machining
A tool unit applied to ultrasonic machining, includes an amplitude transformer, a machining head and a connecting portion. The machining head has a micron-sized array structure. With the connecting portion, the amplitude transformer and the machining head are assembled together and the connecting portion has a change in shape. The machining head includes a substrate and at least one diamond layer. An upper surface of substrate touches the amplitude transformer or the connecting portion. And the diamond layer is disposed on an lower surface of substrate. The material of the substrate is selected from a group of a steel material with thermal expansion coefficient ranged from 10.70×10−6K−1 to 17.30×10−6K−1, tungsten carbide and combination thereof. The material of the diamond layer is selected from a group of a diamond material with thermal expansion coefficient ranged from 1.00×10−6K−1 to 2.50×10−6K−1, a polycrystalline diamond, a diamond sintered body and combination thereof.
