| PURPOSE: To smoothly and quietly cut, obtain an excellent cut surface, expand the life of a tip and improve efficiency by using cast iron which has high damping effect and excellent strength for a main body or parts of a throw-away type tool. CONSTITUTION: Toughened cast iron is applied instead of conventional Cr-Mo steel for a material of main bodies 11, 13 of a throw-away end mill and a face cutter, a supporter 15 and a wedge part 16. Toughened cast iron is applied to the holder 19 of a cutter used for longitudinal cutting processes. Then, as a result of comparison of this article with the conventional ones for cutting of carbon steel by the throw-away end mill, this article shows no chipping and its life is twice as long as the conventional ones while the conventional ones are short in tool life due to chipping. Additionally, this article shows excellent surface roughness in comparison with the conventional one rough in surface, due to vibration and chipping. COPYRIGHT: (C)1992,JPO&Japio | ||||||
