High Quality 20Khz Ultrasonic Drilling Machining For Thick Comosite Materials
Description:
The Ultrasonic drilling machine is a drilling device that uses vibrations in order to hammer its bit through materials, as opposed to traditional drilling methods. The drill uses a piezoelectric actuator as its source of power, and utilizes a variety of 'horns' to vibrate, or hammer, its bit through the material. It was originally designed to be able to drill through very rigid rock surfaces that would otherwise be damaged by a rotary drill, but has also shown potential usefulness to the field of medicine. It is the specific characteristics of the drill that make it ideal or practical for certain situations.
Ultrasonic machining is suitable for processing hard and brittle materials, and can process complex three-dimensional cavities. Traditional ultrasonic machining requires tools that are opposite to the cavities and convexities of the machined cavity. Therefore, the tool is very complicated to manufacture, and the tool has high processing cost and long cycle. Problems such as serious tool wear during processing seriously affect the accuracy and efficiency of processing. Ultrasonic milling is an emerging ultrasonic machining process. It uses simple shape tools, based on the layered manufacturing idea in rapid prototyping, and uses layered removal to process hard and brittle materials. It has simple tool making and small macro force between tools and workpieces. The tool loss can be compensated, and the processing of complex three-dimensional contours can be realized. It is an ultrasonic processing technology with development prospects.

Principle:
The ultrasonic drilling is driven by a Piezoelectric stack actuator that creates the vibrations. The actuator vibrates at an extremely high frequency, making it ultrasonic, and it is these waves of vibration that are transmitted by the horn of the actuator all the way to the bit itself. The vibrations are created at the actuator and are transferred by the horn to a free mass. The free mass vibrates between the drill stem and the horn of the actuator to transmit the vibrations down the drill stem. The drill stem houses the drill bit, and the vibrations push the bit into the material. The repetitive impact on the drill stem by the free mass, creates stress pulses that transmit to the tip of the bit and into the rock. Ultimately, the repetitive strike of the bit produces enough strain on the surface to fracture it.
Competitive Advantages:
- Virtually any hard material can be machined
- Little heat is produced
- Since the motion of the tool is up-and-down vibration rather than rotation as in traditional machining, the holes cut are not limited to circular shapes but can be any shape. Custom "cookie cutter" tools can cut complicated shapes.
- Good surface finish and higher structural integrity is obtained
Applications:
- Various kinds of materials especially fragile rigid material.
- Processing plane, groove, all kinds of form surface (such as spline, gear and thread) and special surface of mould.
- Application area: machining industry, machine tool equipment manufacturing.
- Application occasion: manufacturing enterprise, universities and colleges, scientific research institution, mechanical equipment transformation industry.
