Ultrasonic Machining
Ultrasonic machining (USM) is a type of machining process used for shaping and polishing hard materials. Ultrasonic machining uses high frequency vibrations to break down brittle materials into small particles. The vibration is applied by a rotary wheel that moves back and forth across the workpiece, while an abrasive slurry is sprayed onto the workpiece. As the wheel moves, it pulverizes the material, resulting in a finer finish.
USM has a wide range of applications. It can be used to shape, polish and deburr metals, ceramic, glass and composites. It is often used to create intricate shapes and smooth surfaces that would be difficult to produce with traditional machining methods. USM is also well suited for deburring, since the abrasive slurry suspends any hard particles present in the workpiece.
USM is ideal for creating detailed shapes, since the wheel is constantly in contact with the material. This contact allows the wheel to grind easier and more smoothly along complex curves than with traditional machining processes. USM is also more efficient; the wheel is always being supplied with fresh abrasive slurry to ensure that it is always rotating and cutting at its maximum efficiency.
USM also has a number of advantages over other types of machining. Since the wheel is always in contact with the material, less force is needed to produce a precise machining result. Additionally, USM produces an exceptionally clean finish on even the hardest materials. The process is also highly precise and repeatable; it is capable of producing errors less than one micron (1/1000 of a millimeter).
Lastly, USM requires very little setup and teardown time. The process is simple and requires little user input, allowing for a low cycle time and high throughput.
Overall, USM is a versatile machining process that can be used for a variety of applications. Its precision, high throughput, and low setup times make it an excellent choice for shaping difficult to machine materials.
