    • To provide an electrolytic integrated polishing method for the external surface of metallic tubes, wherein both dimensional precision such as roundness or the like and product yield can be improved, and aluminum alloy photosensitive drum substrates prepared thereby. A metallic tube, both ends of which are supported, is positively charged and rapidly rotated about the axis thereof. More than one grindstone are pressed with a constant pressure against the external surface of the metallic tube from opposite directions or radial directions having the rotation axis as the center of rotation. Negative pole electrodes are disposed so as to sandwich the grindstones along a circular direction to perform electrolytic integrated polishing by supplying electrolyte to the external surface of the metallic tube. High-precision mirror processing of the external surface of the metallic tube can be performed by an integrating abrasion effect for eliminating a passivation coating formed on the external surface of the metallic tube by the grindstones and intensive electrolytic elution by the electrolyte.
    • 为了提供金属管的外表面的电解集成研磨方法,其中可以提高诸如圆度等的尺寸精度和产品成品率,并由此制备铝合金感光鼓底片。 其两端被支撑的金属管被带正电并且围绕其轴线快速旋转。 从旋转轴线为旋转中心的相反方向或径向方向以一定压力将多于一个的研磨石压在金属管的外表面上。 负极电极被设置为沿着圆形方向夹住砂轮,以通过向金属管的外表面供应电解质来进行电解集成抛光。 金属管的外表面的高精度镜面加工可以通过一体化磨损效果进行,以消除由磨石形成在金属管的外表面上的钝化涂层,并且由电解质进行强烈的电解洗脱。

    • A method for manufacturing a mirror surface tube for a photosensitive drum of a copying machine or the like, by which an external surface of an aluminium or aluminium alloy tube can be mirror-processed with high accuracy without surface defects, and in such a way that good quality required for a photosensitive drum is ensured and dimension accuracy, such as roundness, and production yield is improved involves a first step in which an aluminium or aluminium alloy tube, finished in a predetermined shape and dimension with surface roughness of 10 microns or less, is processed by a centerless grinding process. Then, in a second step, a grinding process is performed using an electrolytic integrated polishing apparatus including a tool electrode mechanism having an elastic grindstone so as to make a mirror surface tube having the surface roughness of 2.0 microns or less. Further, preferably, in a third stage, a roller burnishing process is performed to finish the tube to a surface roughness of 0.5 microns or less.
