The hardness of tungsten carbide causes lots of negative effects in using traditional machining, such as severe tool wear and chipped cutting surface.
Electrical discharge machining requires expensive equipment and complicated procedures. Though it’s seemed to be easy to machine tungsten carbide, the subsequent CNC machining assistance is needed for precise feature machining.
In addition to the h shape feature processing, there is threading processing next to it. Processing this feature is time- consuming to electrical discharge machining since it requires multiple and repeated processing to reach the same feature.
With high frequency vibration, HIT ultrasonic machining module reduces the continuous wear between tool and materials so as to increase the tool life.
Every subtle vibration can remove materials slightly and make the machined surface become uniformed, thus enhancing the surface quality.
In the comparison to EDM, ultrasonic machining assisted processing reduces costs of equipment and time.
