Abstract

As industrial technology advances functionally, there is an increasing necessity to treat edges of products well to satisfy the required function. Specifically, burrs inside products at intersecting holes are very difficult to remove because the accessibility of the burr location inside the product to tools is very limited. We propose a new deburring method called abrasive deburring. This method uses a pipe with a hole as a deburring tool to move water with an abrasive and a pump for suction. To determine the suitability of the proposed deburring method, abrasives with different sizes and specific gravities are used. The geometry of the tool and the operating conditions were specified using the following parameters: the diameter of the crossing hole, the diameter of the suction tool, the gap between the sample hole and the tool, the pressure of the pump, and the location of the hole of the tool. The suction-deburring method was very useful for removing micro burrs formed at intersecting holes with an appropriate pump pressure, which is not as high as that in the water-jet or extrude-hone method. However, given the limited deburring force, the method is only applicable for removing micro burrs; other burrs are reduced to stable burrs, which do not require removal from the product.
