End surface polishing machine

An end surface polishing machine comprising:

• a holding disc for holding a plurality of elongated members having end surfaces;
• a polishing disc;
• a support mechanism for supporting the holding disc and placing the end surfaces of the elongated members in contact with the polishing disc;
• and
• a drive mechanism including a rotation motor for rotating the polishing disc about a first axis, a revolution motor for revolving the polishing disc about a second axis, a first rotating disc rotatable about the first axis by the rotation motor, at least one second rotating disc disposed eccentrically on the first rotating disc, a third rotating disc connected to the second rotating disc for rotation about the second axis, a revolution axle supported for revolution around the first axis by the revolution motor and having a through-hole defining a center extending along the second axis, and a rotation axle rotatably disposed within the through-hole and having a first end connected to the third rotating disc and a second end supporting the polishing disc.

An end surface polishing machine comprising:

• a polishing disc;
• a drive mechanism for rotating the polishing disc about a first axis and for revolving the polishing disc about a second axis;
• a holding disc for holding at least one elongated member having an end surface, the holding disc having a first central opening and a second opening, the first opening having a tapered surface, the first and second openings extending along the first axis;
• and a support mechanism for supporting the holding disc, the support mechanism including a pressing member insertable in the first opening of the holding disc and engageable therewith to press the end surface of the elongated member against the polishing disc, the pressing member having a tapered portion for engagement with the tapered surface of the first opening, and a stopper element insertable in the second opening of the holding disc to prevent rotation of the holding disc about the first axis.
