Apr 05, 2019· Ultrasonic Machining Advantages / Merits: The main advantages of Ultrasonic Machining: This process is used for drilling both circular and non-circular holes in very hard materials like carbide, ceramics, etc. This process is best suited for brittle materials. The machining operation is simple and requires less time. This process is economical.
Ultrasonic machining, or strictly speaking the "Ultrasonic vibration machining", is a subtraction manufacturing process that removes material from the surface of a part through high frequency, low amplitude vibrations of a tool against the material surface in the presence of fine abrasive particles. The tool travels vertically or orthogonal to the surface of the part at amplitudes of 0.05 to 0 ...

The process, which is currently in the research state, is called "ultrasonic-assisted" grinding — or "assist" grinding by the technologists working on the development. It should not be confused with "ultrasonic impact grinding" — also called "ultrasonic machining" which is a well-established production process.
Although largely unknown in the MEMS community, micromachining using ultrasonic impact grinding (UIG) is a fascinating yet easy fabrication scheme to achieve virtually any shape, such as a shallow or deep reservoir, a channel, a via, etc, in silicon, glass and other commonly used ceramic and semiconductor materials in the MEMS field.

Ultrasonic Machining . It is also known as Ultrasonic impact grinding is an operation that involves a vibrating tool fluctuating the ultrasonic frequencies in order to remove the material from the work piece.
The ultrasonic machining (USM) process consists of two methods, namely, ultrasonic impact grinding and rotary USM. This article lists the major ultrasonic components that are similar to both rotary USM and ultrasonic impact grinding. It also provides schematic representations of the components used in rotary USM and ultrasonic impact grinding.
Ultrasonic impact grinding (UIG) is an old but virtually unknown technique in the MEMS community which can be used to fabricate small, even ornate patterns in brittle materials such as silicon, glass and ceramics. Although suited primarily for brittle materials, UIG has been used to prepare metallic foils and metal composites [1, 2].

Ultrasonic Wet-Milling and Micro-Grinding. Ultrasonication is an efficient means for the wet-milling and micro-grinding of particles. Besides dispersing and deagglomerating, the wet milling is an important application of Hielscher ultrasonic devices.. In particular for the manufacturing of superfine-size slurries, ultrasound has many advantages, when compared with common size reduction ...
The process is configured into two main types (Fig. 1a–b) depending upon how the force is transferred from the vibrating tool to the work surface.If the transfer of vibration energy is achieved by introducing a liquid containing abrasive grits in the gap between the tool and work surface, the process is called "ultrasonic impact grinding" or simply "ultrasonic machining."
Rotary ultrasonic machining (RUM) is a hybrid machining process that combines the material removal mechanisms of diamond grinding with ultrasonic machining (USM), resulting in higher removal rates than those obtained by either diamond machining or USM alone.
During grinding, drilling and milling this ULTRASONIC superimposition of vibrations has a direct, positive impact on process forces, metal removal performance and tool service life and thus on the machining result in the form of cost efficiency and accuracy.
Working principle of Ultrasonic Machining or Ultrasonic Impact Grinding is described with the help of a schematic diagram. The shaped tool under the actions of mechanical vibration causes the abrasive particles dipped in slurry to be hammered on the .
Process: Ultrasonic machining is a mechanical type non-traditional machining process. It is employed to machine hard and brittle materials (both electrically conductive and non conductive material) having hardness usually greater than 40 HRC. The process was first developed in 1950s and was originally used for finishing EDM surfaces.
