The method is employed to machine hard and brittle materials which are either electrically conducting or non-conducting. Analysis of the mechanism of material removal by USM process indicates that it may sometimes be called Ultrasonic Grinding (USG) Working Principle of Ultrasonic Machining. The figure shows the Ultrasonic machining operation.
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.
lapping & polishing. Silfex provides lapping and polishing capabilities for critical surface finishes for all products Using methods and controls developed in silicon wafer processing, Silfex can meet the precision surface finishes, tolerances and flatness required for most applications.
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, 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.

Experience unprecedented machining efficiency with high performance ultrasonic milling, grinding, core drilling and lightweighting of optical glasses and ceramics. Ultrasonic oscillation of the tool promotes free cutting of material, greatly reducing the force applied to the .
1. An overview of ultrasonic machining and applications. Ultrasonic machining (USM) is a non-conventional mechanical material removal process generally associated with low material removal rates, however its application is not limited by the electrical or chemical characteristics of .
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.
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.
The disclosure relates to an ultrasonic impact grinding apparatus utilizing a counterweight to set an unloaded friction free condition. An added weight is used to optimize feed rate in accordance with the material to be cut, tool size and the like ...
Ultrasonic assisted grinding is an efficient machining process which improves the machinability of hard-to-cut materials by changing the kinematics of the process. In this research, the effect of imposition of ultrasonic vibration on the grinding of Ti6Al4 V alloy is studied.
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.
