Hybrid Processes Of Machining With 20KHz Non-contact Ultrasonic Assisted System

The ultrasonic assisted machining process has been recognized as a leading, non-traditional high-precision machining process. Recently, it has been developed for processing various advanced and difficult-to-process brittle materials, such as reinforced composite materials, ceramics and metal alloys.

The ultrasonic assisted machining can obtain a very high surface finish efficiently and economically. The ultrasonic assisted machining process has also been shown to reduce cutting forces and increase tool life when machining very hard and brittle materials and it was first used in the late 1920s. 

The whole ultrasonic system uses particular resonance theory to optimize the impedance matching of subsystems such as ultrasonic power, transducer, horn and holder, so as to ensure the continuous working stability of the system. Reduce energy consumption and save cost.

The machining technology of SP TECH ultrasonic tool holders is mainly used to reciprocate the tool in a fixed direction at a high-speed frequency of 20,000 to 40,000 times per second by the resonance effect. The amplitude can make the cutting removal in the machining process more effective, therefore simultaneously reducing the cutting force and chipping of hard-to-cut materials as well as optimizing the machined surface.

Since the ultrasonic handles contains electronic components, the power transmission method has become an essential part of the technology. SP TECH ultrasonic machining tool holder module utilizes the non-contact power transmission technology to transmit the electric power on the high-speed rotating tool. A patented precision actuation mechanism inside the tool holder then generates a high-frequency micro-vibration on the cutting tool edge. Neither consumables nor friction which causes tool wear do you need to worry, removing the limitation of the high spindle rotation speed advantage. Which achieves a win-win effect of stable and efficient production.
