Development of Polishing Tool Capable of Self-Adaptive to Processing Site Using Steel Balls and Magnetic Force

Abstract:

There has been the requirement in recent times for environmentally friendly methods for finishing free-form surfaces such as those of molding dies [1]. This has led to interest in the development of a new polishing technology that utilizes less abrasive slurry and magnetic abrasive finishing. However, it is well known that the traditional magnetic polishing method is unstable and produces insufficient surface smoothness. In the present paper, we discuss the causes of the instability of conventional magnetic polishing. We also propose a self-adaptive polishing tool comprising a brush with steel balls and a coating of thin slurry and present the results of its use to polish various incline surfaces on a three-axis machining center. The proposed self-adaptive polishing tool was found to be effective for polishing a free-form surface using less abrasive slurry.
