Abstract
The present disclosure involves various embodiments for finishing the internal wall of a capillary tube. A quantity of abrasive particles and a rod are placed in a capillary tube, wherein a portion of the abrasive particles is magnetic. A magnet is positioned near a side of the capillary tube, thereby attracting the abrasive particles toward an internal wall of the capillary tube. A relative rotation of the capillary tube is produced with respect to the magnet, thereby causing the abrasive particles to finish the internal wall of the capillary tube.

An arrangement, comprising:
- a capillary tube configured to promote a flow of a fluid by a surface tension between the fluid and the capillary tube;
- at least one magnet positioned near a side of the capillary tube;
- a plurality of abrasive particles disposed in the capillary tube within a magnetic field of the at least one magnet, wherein at least a portion of the abrasive particles is magnetic;
- and
- a rod disposed in the capillary tube.
A method, comprising the steps of:
- placing a quantity of abrasive particles and a rod in a capillary tube, wherein a portion of the abrasive particles is magnetic, wherein the capillary tube is configured to promote a flow of a fluid by a surface tension between the fluid and the capillary tube;
- positioning a magnet near a side of the capillary tube, thereby attracting the abrasive particles toward an internal wall of the capillary tube;
- and
- producing a relative rotation of the capillary tube with respect to the magnet, thereby causing the abrasive particles to finish the internal wall of the capillary tube.
