For efficient deburring of burrs that form inside mechanical parts after drilling, new special deburring tool was developed specifically for the burr found at intersecting holes. In this paper, the process for finding ideal cutting conditions has been carried out to identify the efficient performance of deburring using a new tool. The burrs at the entrance and exit surface were analyzed for efficient removal. The surface roughness after deburring was also reviewed for better performance. In addition, the influence of the feed rate on deburring quality was analyzed for improved productivity. Through this process, a new deburring tool can be applied effectively to remove burrs formed at intersecting holes.

The cleanability of machine parts is becoming increasingly important in the industrial field. In particular, cleanability is the most important factor in hydraulic products. The burr and chips are dominant factors of cleanability. If the burrs are not removed completely before the beginning of the machining stage, this will cause many problems, such as scratches and operation failure. Due to the complexity of the valve body itself, it is very difficult to use common deburring tools. In this study, a brush-like deburring tool was suggested and verified as a proper tool for removing the burrs and forming a proper edge shape through a real experiment. Various kinds of brush materials and process conditions were tested for proper deburring of the valve body. It was shown that the suggested method was successful for valve body deburring.

In machining operations, a burr is an undesirable material formed by plastic deformation in a workpiece. With the ongoing industrial developments, it has become an important issue to efficiently remove burrs. Several deburring methods have been developed to remove specific burrs that require special machining. However, to remove burrs formed while machining at the CNC machining center, deburring tools must be developed. In a previous study, a new deburring tool was developed by the authors. In this study, the influence of the rake angle and stiffness of the new deburring tool was analyzed to improve performance. The theoretical model was driven considering the rake angle and stiffness, and experiments were carried out to validate the model. Especially, conditions based on the designed rake angle and stiffness to effectively remove burrs, which is difficult, at the exit surface were suggested.
