摘要： A carriage for a hard disc drive polished as final finish has high surface precision of micron order. The finish surface is smooth, a cutting trace does not exist, and the surface layer is hardened uniformly by a magnetic material being hit by magnetic power. A cutting bur the edge of which is very tiny does not fall after installing the hard disc drive. The carriage for the magnetic head of the hard disc are not influenced by a temperature change and a seasonal change. The present invention forms a magnetic polishing brush by keeping magnetic abrasive material between magnetic poles in the carriage as a head arm member formed by extrusion molding or drawing for the magnetic head of the hard disc drive. The carriage of non-magnetic material as an aluminum part of HDD inserted in the above described magnetic polishing brush, is given reciprocation motion and vibration, thus the surface of the above described part is polished. The final finish is made by magnetic beam processing to polish or remove burs. Further, surface polish as final finish of the carriage is made by the above described magnetic beam processing using feeble magnetism, the relative magnetic permeability of which is 1.5 to 200, as the above described abrasive material. Further, stainless steel, nickel alloy or iron alloy having the same hardness as said stainless steel is used as the above described polish material.
摘要翻译：用于作为最终抛光抛光的硬盘驱动器的托架具有高微米级的高表面精度。精加工表面光滑，不存在切割痕迹，表面层被被磁力击中的磁性材料均匀地硬化。安装硬盘驱动器后，其边缘非常小的切割刀头不会掉落。用于硬盘磁头的托架不受温度变化和季节变化的影响。本发明通过将磁性研磨材料保持在滑架中的磁极之间形成磁性抛光刷，作为通过挤出成型或硬盘驱动器的磁头拉拔而形成的头臂部件。作为插入上述磁性抛光刷中的HDD的铝部件的非磁性材料的滑动被赋予往复运动和振动，因此上述部件的表面被抛光。最后的完成是通过磁束处理来抛光或去除毛刺。此外，作为上述研磨材料，通过上述使用弱磁性（磁导率为1.5〜200）的弱磁体进行上述磁束处理，进行表面抛光。此外，使用与所述不锈钢相同硬度的不锈钢，镍合金或铁合金作为上述抛光材料。

摘要： The present invention provides a method for processing such as deburring, polishing and washing of surfaces of slits of a workpiece, having slits with narrow width from outer surface toward inside, with high accuracy and high efficiency. Magnetic abrasive material is retained in a magnetic field formed between magnetic poles 3 and 4, and magnetic brushes 5 are formed. A workpiece 1 made of non-magnetic material and having slits 1f with narrow width is placed in said magnetic brushes 5, and by relatively vibrating said magnetic poles and said workpiece, surfaces of the slits are processed. It is more effective to tilt the slit surface with respect to the magnetic field after the slit surface is arranged in parallel to the magnetic field.

摘要： The present invention provides a method and an apparatus for surface treatment to polish and wash with high accuracy the inner surface of a member having complicated internal configuration. A magnet 23 is arranged on outer side of a member 1, which is made of a nonmagnetic material and for which surface treatment is to be performed on inner surface. Magnetic grains and abrasive grains in slurry state are supplied to inner surface of the member. At least one of the member 1 and the magnet 23 is rotated and are relatively moved in axial direction at the same time.
