Ultrasonic assisted drilling technology is a kind of drilling technology with 2 – 20 in feed direction. High frequency vibration (> 20 kHz) is applied to the drill tip to improve processing conditions and productivity.
Ultrasonic vibration can not only reduce the thrust, but also improve the surface quality of the hole. In addition, high frequency vibration has no significant effect on the dimensional accuracy or microstructure of the borehole.
Ultrasonic assisted drilling technology is a kind of technology that applies ultrasonic vibration in the feed direction of drill bit to improve drilling conditions and productivity. UAD is superior to traditional drilling technology in reducing thrust and torque, reducing burr height, improving surface roughness and hole accuracy.
In recent years, titanium alloys have been widely used in aerospace and other fields due to their superior properties. However, the high hardness and brittleness of titanium alloy, especially the low thermal conductivity and strong chemical affinity, make it more difficult to process metal materials. Because the aerospace industry needs a large number of high-precision holes, the research on its machining technology has attracted much attention. Ultrasonic vibration assisted drilling technology is very suitable for drilling hard and brittle materials.

Ultrasonic treatment can be used for high speed milling, drilling, grinding and boring. Under the same conditions, the surface roughness can be increased by an order of magnitude. For the hard and brittle material processing, the processing efficiency can be increased by 100% compared with the traditional processing, and the tool life can be increased by more than 3 times.
1. There are a variety of series of tool holders that can be used with the host.
2. It can run continuously without preheating.
3. It is not restricted by whether the material is conductive.
4. The tool has small macroscopic force on the workpiece and low thermal effect, so it can process thin-walled, narrow-slit and thin-walled workpieces.
5. The greater the brittleness of the material to be processed, the easier it is to process, the harder the material or the greater its strength and toughness, the more difficult it is to process; because the material of the workpiece is broken down mainly by the action of abrasive, the hardness of the abrasive should be higher than that of the material to be processed. The hardness of the tool can be lower than that of the workpiece material.
6. It can be combined with many other processing methods, such as ultrasonic vibration cutting, ultrasonic electric discharge machining and ultrasonic electrochemical machining.
