20khz Ultrasonic Assisted Drilling Machining For CNC Machines

It works in the same way as ultrasonic welding. This process uses ultrasonic waves to generate low-amplitude high-frequency forces that act as a driving force for the abrasive. This high frequency vibration transfer to the abrasive particles is contained in the abrasive slurry. This causes the abrasive particles to be indented to the brittle workpiece and removed from the contact surface.

Power Source:

As we know, this machining process requires high frequency ultrasonic wave. So a high frequency high voltage power supply require for this process. This unit converts low frequency electric voltage (60 Hz) into high frequency electric voltage (20k Hz).

Magnetostrictive Transducer:

As we know, transducer is a device which converts electric single into mechanical vibration. In ultrasonic machining magnetostrictive type transducer is used to generate mechanical vibration.  This transducer is made by nickel or nickel alloy.


The mechanical vibration generated by transducer is passes through booster which amplify it and supply to the horn.


The tool used in ultrasonic machining should be such that indentation by abrasive particle, does not leads to brittle fracture of it. Thus the tool is made by tough, strong and ductile materials like steel, stainless steel etc.

Tool holder or Horn:

As the name implies this unit connects the tool to the transducer. It transfers amplified vibration from booster to the tool. It should have high endurance limit.

Abrasive Slurry:

A water based slurry of abrasive particle used as abrasive slurry in ultrasonic machining. Silicon carbide, aluminum oxide, boron carbide are used as abrasive particle in this slurry. A slurry delivery and return mechanism is also used in USM.


The application of ultrasonic technology in industry began in the 1920s. It is based on classical acoustic theory and combines integrated technologies in the fields of electronics, metrology, mechanical vibration and materials science. 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,


1. The process is non-thermal, non-chemical, non-electric, leaving the chemical and physical properties of the workpiece unchanged. This low stress process provides high reliability for your critical applications.

2. Multiple features can be processed simultaneously at the wafer or substrate level and the process is scalable. Our processes are usually the highest quality and lowest cost solutions.

3. Ultrasonic machining features vertical sidewalls that allow you to retain valuable space for your design for increased productivity.
