20Khz high power Ultrasonic impact grinding Ultrasonic machining

Ultrasonic Machining 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 process involves an abrasive slurry that runs between the tool and the work piece. Due to this, the tool and the work piece never interact with each other. The process rarely exceeds two pounds.

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 0.125 mm (0.002 to 0.005 in.). The fine abrasive grains are mixed with water to form a slurry that is distributed across the part and the tip of the tool. Typical grain sizes of the abrasive material range from 100 to 1000, where smaller grains (higher grain number) produce smoother surface finishes.

Ultrasonic vibration machining is typically used on brittle materials as well as materials with a high hardness due to the micro-cracking mechanics.

Working Principle of Ultrasonic Machining
The time spent on ultrasonic machine entirely depends on the frequency of the vibrating tool. It also depends on the size of grains of the abrasive slurry, the rigidity and the viscosity as well. The grains used in the abrasive fluid are usually boron carbide or silicon carbide as they are rigid than others. The used abrasive can be carried away easily if the viscosity of the slurry fluid is less.

Ultrasonic Machining Advantages and Disadvantages
Get to know about the advantages and disadvantages of machining process in order to make the right decision:

Advantages
Machined all sorts of hard materials
Produces fine finished and structured results
Produces less heat
Various hole cut shapes due to vibratory motion of the tool

Disadvantages
Requires a higher degree of integrity and skills
No certified record of radiography
Additional repairs might be required due to spurious signs and misunderstanding of the process

Ultrasonic machines are the future of machining which is used all over the world for creating hard and brittle forms of materials for the industrial uses. A lot of operations can be performed with the ultrasonic machine which can benefit the industrialists in a variety of ways. The advanced technology creates solution which helps in opening up the market opportunities and has made things easier.
