Description of the Related Art Conventionally, in order to hold a ball of a metal ball pen tip such as brass, nickel silver, stainless steel, copper alloy, aluminum alloy, etc., a center hole of the ball pen tip and a ball holding chamber. After forming the internal structure such as by cutting, etc., the ball is installed in the ball holding chamber, and the tip of the ball pen tip is caulked to form a reduced diameter portion to form the ball. There is known a ball-point pen chip that holds a part of a ball while holding it.

All of these things become a catch on the writing surface such as paper surface,
Not only does it increase the frictional resistance during writing, but it also damages the surface to be written, and there is the problem that handwriting is disturbed by ink penetration into the damaged area. It has been desired to form the outer shape of the tip portion that is likely to come into contact with a smooth curved shape.

The abrasives that are also undergoing scraping. If the abrasive is used for a long period of time, the part used (the part that comes into contact with the material) is scraped, and if the absolute position of the abrasive is determined, the abrasive does not come into contact with the material to be processed.
Also, for those that determine the relative position with respect to the material to be processed, the life of the abrasive is short because it abuts with a minimum force that abuts the material in the state of a new abrasive, and
There is a risk that the tip portion of the ball-point pen tip will be distorted if it is brought into contact with an excessively strong force, and there is a problem in terms of work efficiency due to the necessity of making delicate adjustments according to the variations of the ball-point pen tips.

Even if the abutting force of the abrasive material to be abutted against is somewhat excessive, the excessive amount of the abutting force can be absorbed by the bending amount of the synthetic resin pipe. Further, the delicate adjustment of the contact force can be easily and surely adjusted by adjusting the distance between the holding position of the synthetic resin pipe and the abrasive.

Can be formed to increase the coefficient of friction. Further, in order to prevent the surface of the synthetic resin pipe 2 from being damaged on the contact surface 3e of the receiving roller-3b with respect to the synthetic resin pipe 2, a synthetic resin sheet or cloth is attached or the receiving roller 3b is attached. La-3b itself can be formed of synthetic resin.

The polishing surface 4c is formed of a cloth such as felt or cotton, a fiber converging body such as cotton or silk, or leather such as deer leather or cow leather. The ball pen tip 1 is rotated while rotating.
A ball pen tip 1 that increases friction resistance at the time of writing by abutting against a writing surface such as a corner portion formed on the outer shape of the ball-pen tip 1 or fine processing lines or scratches or burrs, It is removed to form a smooth curved surface. Here, if a polishing agent such as fine powder of chromium oxide, silicon carbide, aluminum oxide or diamond powder is applied to the polishing surface 4c, the polishing effect can be efficiently obtained.

離を縮めればよい。The contact position of the abrasive 4a with the ball-point pen tip 1 is displaced from the position where the rotary machine 3 holds the synthetic resin pipe 2 described above. By doing so, the synthetic resin pipe 2 is bent. In order to adjust the bending amount, a large bending amount is required by adjusting the distance between the position where the rotary machine 3 serving as the fulcrum holds the synthetic resin pipe 2 and the contact position of the abrasive 4a with the ball-pen tip 1. In that case, the distance may be increased, and if a small amount of bending is required, the distance may be reduced.

ものとなる。In the rotation direction A of the abrasive 4a indicated by the arrow in the drawing, when polishing is performed from the synthetic resin pipe 2 side of the ball-pen tip 1 toward the tip 1a side, the powdery abrasive is blown. It is preferable in that it is difficult for the rupen tip to enter the inner hole. Further, as shown in FIG. 2, when the rotary shaft 4b is displaced 90 degrees from that of FIG. 1 and polishing is performed in a direction perpendicular to the longitudinal direction of the ball-point pen tip 1, the durability of the abrasive is improved and the life is increased. Is preferable in that it becomes longer.
