MAGIC 숫돌에 의한 연마작업의 표준화(연마입자의 종류와 배합율이 연마면 조도에 미치는 영향)

Standardization of polishing work by MAGIC wheel (Influence of composition ratio and kind of polishing grain on polishing surface roughness )

In order to polish complicated shaped inner surfaces of molds, a new polishing method with consolation liquid was Invented The MAGIC (MAGnetic Intelligent Compound) Polishing is the best method, a countermeasure of polishing trouble that is reduce of productivity and instability of quality. But because MAGIC polishing is new polishing method there is no study of the standardization of polishing by MAGIC wheel yet. So we want to standadize MAGIC polishing condition. For the First time, we will evaluate the influence of composition ratio and kind of polishing grain in polishing surface roughness. In this study, we determined amount of dressing oil and dressing point as kind and composition ratio of polishing grain. we compared surface roughness case by case
