Proposal of automatic polishing method for die

精密模具制造自动化技术近年来取得了显著的发展。然而，目前模具的抛光工作仍然依赖于人工操作。由于这个原因，模具形状变得更加复杂，并且无法使用传统的砂轮进行抛光。提出了一种新型粘结磨料抛光轮，介绍了其制造工艺及特点。这种制造方法的原理和特点不同于传统的砂轮。在这里，这种新的抛光轮被称为MAGIC（磁性智能化合物）。这种轮子有以下许多优点。(1)采用传递法可以制造出适合各种模具形状的砂轮。(2)利用磁粉和磁场，可以制造出磨粒均匀性和分散性都很好的抛光轮。(3)加热溶解后，可进行车轮整形。所有这些都可以在工厂里简单地进行。通过抛光实验表明，该材料具有稳定的抛光特性。

Automatic technology of the precision die manufacturing has accomplished remarkable development recently. However, the polishing work of the die depends still on the manual operation at the present time. As this reason, the die shape became complicated more and the application of conventional grinding wheel is impossible to polish. In this study, a new polishing wheel consisted of bonding abrasive was proposed and the manufacturing technique and characteristics of it were introduced. Principle and features of this manufacturing are different from the conventional grinding wheel. Here this new polishing wheel shall be called MAGIC (MAGnetic Intelligent Compounds). This wheel has many advantages as follows. (1) It is possible to make the wheel which is suitable for various die shapes using the transfer method. (2) By utilizing magnetic particle and magnetic field, the polishing wheel which was excellent in the uniformity and dispersiveness of abrasive grain was able to be manufactured. (3) The wheel reshaping is possible if it is dissolved by the heating. (4) All of them can be simply carried out in the factory. Then it was shown that stabilized polishing characteristics could be expected from the polishing experiment.
