Abstract
Despite the large number of methods available for deburring the outside of parts, it is difficult to remove burrs on the inside of small and long parts. Here, a new magnetic internal deburring method is proposed. This method applies a magnetic field-assisted machining process using a magnetic machining jig (permanent magnet tool). The machining force applied to the magnetic machining jig can be controlled freely by adjusting the clearance between the outside pole and magnetic machining jig. A flexible half-fixed finishing behavior can be obtained, because finishing can be achieved through magnetic particles attracted to the magnetic machining jig. In this study, we examined deburring of a hole drilled on the inside of SUS304 stainless steel tubing. The results showed that internal burrs could be removed using this magnetic deburring process.
