Principle:
The ultrasonic spindle system comprises of an ultrasonic spindle, a power supply, and a motor speed
controller. The power supply converts 60 Hz electrical supply to high frequency (20 kHz) AC output. This
is fed to the piezoelectric transducer located in the ultrasonic spindle. The ultrasonic transducer converts
electrical input into mechanical vibrations. The motor attached atop the ultrasonic spindle supplies the rotational
motion of the tool and different speeds can be obtained by adjusting the motor speed controller.
Functions:
- The tool with ultrasonic vibration wear rate was lower than that for Tool without vibration.
- ultrasonic vibration assisted drilling of glass, the tool wear without vibration was approximately twice of that with vibration.
- The cutting force was significantly reduced (about 20%) with rotary ultrasonic machining compared to diamond grinding.
- The roughness value was reduced by 85% with ultrasonic vibration, a significant roughness improvement. And the roughness could be either increased or decrease, depending on the vibration amplitude.
Applications:
Improvements led to the development of a machine comprising a rotating ultrasonic transducer. The rotating
transducer head made it possible to precisely machine stationary workpieces to close tolerances. With
different shaped tools, the range of operations could be extended to end milling, tee slotting, dovetail cutting,
screw threading, and internal and external grinding.
