することによりメッキを行なう。The connecting-type plating shaft of the present invention is divided into two or more at the center shaft, has a magnetic disk groove on the outer peripheral surface, and has a step portion fitted to the connecting portion. A splice support is fitted and two or more splice supports are attached to the shaft, and both ends of the central shaft are covered with end caps having step portions matching the step portions of the splice support. The both ends are screwed to the bolts implanted in the rotating disk by the drilled bolt holes. Plating is performed by immersing a plurality of aluminum substrates for magnetic disks attached to the outer peripheral grooves of the joint support with the shaft in a plating tank.

い。FIG. 1 shows an embodiment of a connecting type plating shaft according to the present invention, wherein 1 denotes a central shaft, and S denotes a central shaft.
It is made of a material such as US, and a plurality of joint supports 3 are inserted around its outer periphery. The joining support 3 is formed of a peak material (polyetherketone) or the like, and a groove 5 is provided on an outer peripheral surface thereof so that an aluminum substrate 4 for a magnetic disk can be suspended at a predetermined interval, and both ends are adjacent to each other. A step portion 6 is provided in which the joint supports are fitted. Two or more splicing supports are inserted into the central shaft 1, and end caps 7 having stepped portions matching the stepped portions 6 of the splicing support 3 are attached to both ends thereof by fitting the stepped portions 6. A bolt hole 8 is provided at the center of the outer end of the end cap 7,
Both ends of the shaft are screwed by bolts 10 implanted in the rotating disk 9. The inner step portion of the joint support 3 is shown in FIG.
As shown in (1), a space portion 11 that forms an air pocket when the joint supports are fitted may be provided.

る。According to the present invention as described above, since the shaft is configured to be supported at both ends, the runout is significantly reduced, the contact between the aluminum substrates for the magnetic disk is avoided, and good plating is achieved. I can do it. In addition, since the splicing support is divided into a plurality of parts and a step portion that matches each other is provided, there is almost no runout compared to the case of connecting with bolts, and it is inexpensive because it is only necessary to replace the splicing support of the damaged part is there. Furthermore, unlike the conventional shaft, it is not necessary to increase the diameter of the base portion of the shaft, so that the shaft can be machined from a material having a predetermined joint support diameter, so that the machining cost can be reduced and a lightweight shaft can be obtained.
