20KHz New Developed Ultrasonic Assisted System For CNC Machining

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.
