The invention discloses a miniature steel wire ball machine comprising a base (1); the base (1) is provided with a paying-off support (11) provided with a steel wire (2); the steel wire (2) passes through a space between two needle bearings (6) by a supporting seat (4) and reaches a disk feeder (8) by a motor (7); the supporting seat (4) is provided with a regulating nut (3); the motor (7) drives a gear (9) by a belt (10); and the needle bearings (6) are arranged in the gear (9). The miniature steel wire ball machine disclosed by the invention is simple in manufacturing process and can be purchased and used by every family. A steel wire ball is manufactured by water wire drawing, is incapable of being stained with oil and rusting, bright and clean, soft and elastic and is woven to be in an inner spiral way, high in stubborn stain removal capacity, no scraps fall off, and a cleaning ball raw material cannot injure hands and the surfaces of objects, so that the steel wire ball can be repeatedly used for a long term. Balls with expected sizes can be machined by using the miniature steel wire ball machine, so that the miniature steel wire ball machine is very wide in application range. In addition, the miniature steel wire ball machine is relatively light and is also relatively portable.
