Abstract
To provide a manufacturing method of wheels which can easily and beautifully remove plating at the welding planned portion and which can manufacture wheels with rims plated at low price and efficiently. A method for manufacturing two-piece type wheels having a rim 2 and a disk, in which after providing a chromium plating to the rim 2 as a wheel component member, a welding planned portion RW with respect to the disk on the inner circumferential surface of the rim is ground by a grinding belt 29, removing plating at the welding planned portion RW, thereafter the disk is fitted and fixed to the rim 2 so that the disk and the rim are welded and joined along the welding planned portion RW.
Claims3
1-4. (canceled)
A method for manufacturing three-piece type wheels having an inner rim, an outer rim, and a disk, comprising steps of:
- providing a chromium plating treatment to the outer rim as a wheel component member;
- grinding a welding planned portion on an outer circumferential surface of a curved portion linked from a superimposed parts of rims to a cylindrical body part in the outer rim by an abrasive cloth/paper to remove plating of the welding planned portion;
- assembling both of the rims by superimposing the superimposed parts while superimposing an outer circumferential parts of the disk to the superimposed parts;
- fixing the disk to the superimposed parts with bolts;
- and
- welding to join the welding planned portions of both of the rims from an outside.
