  • As the industrial development is accelerated, a new machining process and system are keenly required to achieve super precision surface finish. Especially to get ground surface finish fer complicated and narrow inner shape of molds, it is impossible with the existing methods so that a new method is being required to be developed. A new material, called Magic(MAGnetic Intelligent Compounds), is finally made and it is called Magic machining that uses this material. There is a way to make a material as follows, the mixture of magnetic particles, bonding material and particles of abrasive grain should be melt down by proper heat, and then this mixture put in a mold and cool down in magnetic field which has a uniform direction. This new polishing method is spotlighted as an excellent solution to the existing problems. However it hasn't reported any study about the influence of the machining conditions of polishing velocity, amplitude and polishing pressure to the surface roughness yet. This study would examine closely the influence of polishing conditions of the Magic polishing tool to the surface finish to decide the optimum polishing condition and to standardize the Magic polishing work.

  • Recently, new polishing system which was made by magnetic intelligent compound (MAGIC) was invented and, the study is going on for practical use the analysis of factors, that is, the kind of polishing grain, composition ratio of wheel elements, machining frequency, polishing pressure, which the main influence for polishing efficiency are the first step. In this study, analyzed influence of wheel raw material composition ratio on 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

  • Recently, new polishing tool which was made by magnetic intelligent compound(Magic) was invented. The distribution of abrasives in this new tool can be controlled by magnetic field. Therefore, we can make a special polishing tool which has well arranged abrasives after cooling. In this study, 3 dimensional polishing machine was developed in order to polish complicated - shaped inner surfaces of molds. The performance of developed machine was investigated by measuring the roughness of polished surface using new polishing tool.
