ABSTRACT:
A simple and efficient method of manufacturing a syringe needle is provided herein, which involves spreading a resin solution on the entire inside and outside of a cut stainless steel tube having the dimensions of a syringe needle, hardening the resin on the inside and outside of said cut tube, removing the hardened resin from the outside of the cut tube, grinding one end of the tube with a grinder to form a main bevel, changing the contact angle between the grinder and the cut tube to form side bevels to produce a syringe needle tube having a piercing point at the ground edge of said tube, and washing away grinding materials and pollutants from the tube.
