H%s"or)The process was first developed in 1950sand was originally used for finishing

surfaces.first using of ultrasonic in the beginning of20th century.

In 1960 ultrasonic machine tools of various

type and size are introduced in market.

I$"ro*u&"%o$Also Known as Ultrasonic Impact Grinding.

Vibrating tool at ultrasonic frequency.

Use of abrasive slurry.

Very little heat generated.

m#&'%$eUltrasonic Machining is a non-traditionalprocess, in which abrasives contained in a

slurry are driven against the work by a tooloscillating at low amplitude and highfrequency.

App!%"%o$s Machining of cavities in electrically non-conductive

materials.

Used to machine fragile components.

Used for multistep processing. Circular as well as non circular holes can be done

with straight or curved axis.


17/26

App!%"%o$s Used for machining hard brittle metallic alloys

semiconductors glass ceramics carbides etc.

Used for machining round s!uare irregular shaped

holes and surface impressions.

Used in machining of dies for wire drawing

punching and blan"ing operations.


18/26

App!%"%o$s U#M has been used for piercing of dies and for

parting off and blan"ing operations.

U#M enables a dentist to drill a hole of any shape on

teeth without any pain.

$errites and steel parts mineral stones can be

machined using U#M.


19/26

App!%"%o$s%t has been proved successful in machining silicon

!uart&.

U#M is used for grinding 'uart& (lass ceramics.

Cutting holes with curved or spiral centre lines and

cutting threads in glass and mineral.


20/26

App!%"%o$sU#M can perform machining operations li"e drilling

grinding and milling operations on all materials which

can be treated suitably with abrasives.

)arge number of holes of small diameter. *+, holes

with ,.+mm has been reported using hypodermic

needles.

conductive material.

o heat is generated in wor" therefore no significant

changes in physical structure of wor" material.

A*/#$"#.es on-metal 0because of the poor electrical

conductivity1 that cannot be machined by 23M and

2CM can very well be machined by U#M.

%t is burr less and distortion less processes.

%t can be adopted in con4unction with other newtechnologies li"e 23M2CM.

%s#*/#$"#.es5ool wear rate is high due to abrasive particles. 5ools

made from brass tungsten carbide M# or tool steelwill wear from the action of abrasive.

U#M can be used only when the hardness of wor" is

more than 67 89C.
