Abstract
A small test piece polishing apparatus is provided which is less likely to bend or damage a small test piece, which is superior in working efficiency, and which ensures uniform quality for the small test pieces produced. The small test piece polishing apparatus 1 for polishing a surface of a small test piece 3 having a circular cross section using a string-type member 13 includes string-type member delivery/recovery means 10, abrasive applying means 20, holding/rotating means 30, and pressing/scanning means 40. The abrasive applying means 20 applies an abrasive to the string-type member delivered by the string-type member delivery/recovery means 10. Thereafter, the pressing/scanning means 40 presses the string-type member 13 applied with the abrasive against the small test piece 3 held and rotated by the holding/rotating means 30 to perform scanning, to thereby polish the small test piece 3.
