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 2018-11-30 ㈜디버텍

Abrasive Flow Media Silicone based viscoelastic polymer whose shearing force is changed by viscosity. Depending on application, it consists of -Diamond -SiC -Boron -AI2O3 2018-11-30 ㈜디버텍

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. 2018-11-30 ㈜디버텍

Deburring and radiusing of productive components Application Area Polishing of Dies Deburring and radiusing of productive components 2018-11-30 ㈜디버텍

Mold - Drawing - Cold forging - Powder metallurgy Process time - Extrusion - Drawing - Cold forging - Powder metallurgy Process time 5 – 60 min. 2018-11-30 ㈜디버텍

Productive components Fuel injection system Pump and impeller Valve body Fittings for Semiconductor, Medical device and Food processing line. 2018-11-30 ㈜디버텍

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 2018-11-30 ㈜디버텍

Application Example Improving flow rate by deburring, polishing and radiusing on spray holes 2018-11-30 ㈜디버텍

Increasing durability by generating Radius on intersecting feed hole 2018-11-30 ㈜디버텍
