Details. The 3-axes ultrasonic machining centre (USM) is one of the unique facilities in India. This machine is similar to a conventional milling machine with a special attachment of ultrasonic generator to generate the ultrasonic motion of 20 KHz, which will be directly transformed through the special spindle and tool holder and is used for milling/grinding.
Ultrasonic Horn for Cylindrical Grinding Machine https:// Ultrasonic machining, also known as …
An ultrasonic horn (also known as acoustic horn, sonotrode, acoustic waveguide, ultrasonic probe) is a tapering metal bar commonly used for augmenting the oscillation displacement amplitude provided by an ultrasonic transducer operating at the low end of the ultrasonic frequency spectrum (commonly between 15 and 100 kHz). The device is necessary because …

In this paper, a ultrasonic horn, which can vibrate longitudinally with a frequency of 20㎑, was designed using finite element method (FEM). And the ultrasonic horn was fabricated for ultrasonic assisted grinding. To evaluate machining performance of the fabricated ultrasonic horn, grinding test was conducted on alumina ceramic (Al2O3). In the grinding test, …
The horn may be solid (typically hardened steel, figure 4) or may have a replaceable multi-lobed welding tip (Holze[1] patent 3,813,006; see figure 5 and Appendix A; see setup).The ultrasonic stack is often mounted in some type of cylindrical shell (e.g., the polar mount of figure 6) that allows rotation about the stack (polar) axis so that the multi-lobed tip can be properly oriented …
The tool never contacts the workpiece and as a result the grinding pressure is rarely more than 2 pounds, which makes this operation perfect for machining extremely hard and brittle materials, such as glass, sapphire, ruby, diamond, and ceramics.
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 …

Ultrasonics offer a fast, clean, efficient method for bonding polysulfone to itself. Welds can be obtained with a 0.5 second ultrasonic time. This welding cycle is much shorter than that of any other method. A standard cylindrical step horn under 40 psi (0.3 MPa) air cylinder pressure has given good results.
