Ultrasonic drilling :
The 20khz Rotary Ultrasonic Drilling Device 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.
Principle:
The 20khz Rotary Ultrasonic Drilling Device 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.
Features:
● Products for standardized production, high reliability;
● Compatible with existing milling machine or machining center interface, can be installed directly;
● Ultrasonic system amplitude stability, continuous working time is long;
● The use of ultrasonic digital control generator, all-digital circuit control, anti-interference ability;
● Frequency, power can be real-time monitoring, power 30-99% adjustable, with automatic alarm protection, easy to operate;
● According to customer requirements, it can be customized.
Applications
1. Various kinds of materials especially fragile rigid material.
2. Processing plane, groove, all kinds of form surface (such as spline, gear and thread) and special surface of mould.
3. Application area: machining industry, machine tool equipment manufacturing.
4. Application occasion: manufacturing enterprise, universities and colleges, scientific research institution, mechanical equipment transformation industry.
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
