Abstract
A polishing apparatus comprises a holder having rod-shaped members each having an end portion to be polished. The rod-shaped members are positioned on the holder so that respective distances between the rod-shaped members and a center of the holder are different from one another. When relative motion is effected between the holder and the polishing member while maintaining distances between a center of the polishing member and the respective rod-shaped members different from one another and while pressing the respective end portions of the rod-shaped members against the polishing member, the respective end portions of the rod-shaped members are polished.
Claims11
A method of polishing end surfaces of rod-shaped members comprising the steps of:
- mounting a plurality of rod-shaped members on a holder to position the rod-shaped members so that respective distances between the rod-shaped members and a center of the holder are different from one another;
- and
- causing a relative trochoid curvilinear motion between the holder and a polishing disc disposed opposite the holder while maintaining distances between a center of the polishing disc and the respective rod-shaped members different from one another and while pressing respective tip ends of the rod-shaped members against the polishing disc so that the respective tip ends of the rod-shaped members are polished.
A method of polishing end surfaces of rod-shaped members comprising the steps of:
- providing a holder having a plurality of rod-shaped members positioned so that respective distances between the rod-shaped members and a center of the holder are different from one another;
- providing a polishing member having a polishing surface;
- and effecting relative motion between the holder and the polishing member while pressing respective tip ends of the rod-shaped members against the polishing surface of the polishing member to polish the respective tip ends of the rod-shaped members.
A method of polishing end surfaces of rod-shaped members comprising the steps of:
- providing a holder having a plurality of rod-shaped members mounted thereon so that respective distances between the rod-shaped members and a center of the holder are different from one another;
- providing a polishing member having a polishing surface;
- and effecting relative motion between the holder and the polishing member while maintaining distances between a center of the polishing member and the respective rod-shaped members different from one another and while pressing respective tip ends of the rod-shaped members against the polishing surface of the polishing member to polish the respective tip ends of the rod-shaped members.
A polishing apparatus comprising:
- a holder having a plurality of rod-shaped members each having an end portion to be polished, the rod-shaped members being positioned at different distances from a center of the holder;
- and a polishing member having a polishing surface for polishing the respective end portions of the rod-shaped members;
- whereby when relative motion is effected between the holder and the polishing member while pressing the respective end portions of the rod-shaped members against the polishing member, the respective end portions of the rod-shaped members are polished.
