3. Process principle
Workpiece is fixed in two vertical opposing cylinders
which extrude the abrasive
flow media up and down
by hydraulic force to get required ;
- Polishing
- Deburring
- Radiusing
㈜디버텍

4. Abrasive Flow Media
Silicone based viscoelastic polymer whose shearing force is changed by viscosity.
Depending on application,
it consists of
-Diamond
-SiC
-Boron
-AI2O3
㈜디버텍

5. Process Parameters Machining Pressure -> 10 ~ 140 bar
The number of cycles
Type of abrasive flow media (viscosity, grit size)
Polishing - > High viscosity
Deburring - > Low viscosity
Tooling which provides passage of abrasive flow media between workpiece and tooling.

9. Application Effect Processing internally inaccessible area
Improving surface profile -> Ra 0.05 um
Deburring small intersecting holes (0.1 mm)
Processing several products at same time
in case of same products.
Removing heat recast layer which is occurred
when part is processed
->Relieving residual stress and improving fatigue strength
Improving flow resistance and transmissibility
->Increasing durability, improving quality and
extending life
