Little heat produced Ultrasonic Abrasive Processing For Ceramic or
Diamonds Impact Grinding
Ultrasonic machining is changing the manufacturing industries with
its superlative performance. The main reason why this machining
process is used in the manufacturing area is because it evolves
less heat in the process. All the operations done with the
ultrasonic machining method are cost effective and best in results.
Ultrasonic machining is an abrasive process which can create any
material into hard and brittle form with the help of its vibrating
tool and the indirect passage of abrasive particles towards the
work piece. It is a low material removal rate machining process.
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.
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 processing features:
1.It is not limited by the conductivity of materials. It is
suitable for punching, cutting, grooving, nesting, engraving, etc.
of various hard and brittle materials such as glass, quartz,
ceramic, silicon, ferrite, gemstone and jade. Batch deburring of
small parts, surface polishing of the mold and dressing of the
2.The processing precision is high and the surface quality is high.
The aperture diameter of ultrasonic drilling is 0.1~90mm, the
processing depth can reach more than 100mm, and the precision of
the hole can reach 0.02~0.05mm. The surface roughness of the glass
treated with W40 boron carbide abrasive can reach 1.25~0.63um, the
processed hard alloy can reach 0.63~0.32um, and the processed
surface has no structural change, residual stress and burn.
3.The tool has small macroscopic force on the workpiece, small heat
influence, can process thin wall, narrow slit and sheet workpiece,
and can process various complex cavities and profiles as long as
the workpiece is made into corresponding shapes and sizes.
4.Since the scraping of the workpiece material mainly depends on
the action of the abrasive, the final hardness should be higher
than the hardness of the material to be processed, and the hardness
of the tool can be lower than the hardness of the workpiece
5.There is no need to make the tool and the workpiece make
relatively complicated relative movements. Therefore, the structure
of the ultrasonic machining machine is relatively simple, and the
operation and maintenance are convenient.
6.Ultrasonic machining can be combined with other traditional or
special processing, such as ultrasonic vibration cutting,
ultrasonic vibration grinding, ultrasonic electric spark machining
and ultrasonic electrolytic composite processing, which can improve
the processing and obtain better processing results.
