Ultrasonic machining, a precision machining technology, has been
used in the machining of these hard materials which show
exceptional cutting strength and low thermal conductivity, and
resistance to abrasion, corrosion, pressure and high temperature.
In addition, ultrasinic machining is a promising machining method
for hard machining because of its high machining stability. This
technique is widely used to produce high quality mirror-surface
finished products in recent advanced technological applications to
meet all aspects of growing markets. This technique results in
cleaner handling, a noticeable reduction of deep cracks in the
material, the reduction of machining steps and the elimination of
electrode machining which in turn reduces the cutting cost, avoids
wastage and improves product quality.
1 Low machining force, about 1/10 to 1/3 of conventional machining
2 High machining accuracy, depends on the machine precision,and
geometric tolerance of workpiece close to machine tool%27s
3 Low machining temperature, workpiece keep in a room temperature
4 No built-up edge, No burr, Little deformation.
5 Low roughness of cutting surface, reach Ra0.2 below, close to the
6 The rigid change of processing components, compared with common
machining, equivalent to improve the rigid.
7 Machining stably, effectively eliminate the chatter.
8 Machining tool durability improves from several times to dozen of
9 Processing surface is under compressive stress, extending the
workpiece fatigue strength wear resistance, and corrosion
Ultrasonic machining can be widely used in areospace, war industry,
hard and brittle materials machining, etc.
1 Machining difficult-to-machine materials: such as heat resistant
steel, titanium alloy, constant modulus alloy, superalloy,
stainless steel, cast iron, engineering ceramic, composite material
2 Machining hardened steel and superhard parts,ultrasonic can
achieve high accuracy and high quality surface, even machining
hardened steel over HRC60 easily, such as high speed steel paper,
bearing steel, etc.; Machining hard alloy with PCD tool can greatly
improve the durability of tools.
3 Forming machining: machining all types of curved surface, sphere,
transition radii, conical surface with molding cutting tool.
4 Machining slender bars and thin walled parts.
5 Machining superfine diameter parts.
