Advanced Technology Rotary Ultrasonic Assisted Machining For Hard And Brittle Material

The application of ultrasonic technology in machining can be divided into two categories according to the characteristics of its processing technology. One is to use ultrasonic abrasive treatment with abrasives, such as ultrasonic hole processing, ultrasonic grinding, ultrasonic polishing, ultrasonic deburring and the like. The other is ultrasonic machining combined with cutting tools and other machining methods such as rotary ultrasonic drilling, grinding and milling. Ultrasonic electrochemistry, ultrasonic vibration cutting,

Ultrasonic drilling is an unconventional loose abrasive processing process. Ultrasound is a sound wave with a frequency higher than 20,000 Hz. 

Ultrasonic can be generated using mechanical, electromagnetic and thermal energy sources. They can be produced from gases (including air), liquids and solids.

During ultrasonic drilling, the material is removed by micro-grinding or abrasive particle erosion. 

The tool oscillates at a frequency of approximately 20 kHz by a piezoelectric sensor and an electric oscillator. The tool forces the abrasive grit to normally impact the work surface in the gap between the tool and the workpiece to machine the work surface.

The smaller the grit size, the smaller the momentum received from the tool. As the tool continues to move downward, the force acting on the larger coarse particles increases rapidly, so some coarse particles may break. Eventually, at the end of its stroke, the sand with a size greater than the minimum gap will penetrate the tool and the work surface to varying degrees.


1. A variety of materials, especially fragile rigid materials.

2. Machining planes, grooves, various shapes of surfaces (such as splines, gears and threads) and special surfaces of the mold.

3. Application areas: mechanical processing industry, machine tool equipment manufacturing.

Application: Manufacturing enterprises, universities, research institutions, machinery and equipment transformation industry.

Competitive advantages:

1.Can process almost any hard material

2.The heat generated is very small

3.Since the movement of the tool is a vibration up and down rather than a rotation in a conventional process, the hole cutting is not limited to a circle, but may be any shape. The custom "cookie cutter" tool cuts complex shapes.

4.Get good surface finish and higher structural integrity
