这种铰刀(见图)用于高强度耐热合金等材料的小孔铰削。其特点为: 1.刀齿材料为YW2硬质合金,刀体材料为9 CrSi,刀齿和刀体用粘结剂粘成一体。刀具前导部分尺寸为0.5×45°,主刀刃为1×18°,校正部分长度为10毫米,做成倒锥。 2.用直刀片,容屑槽为15°螺旋槽,装刀片的槽用15°斜槽。为了保证刀片与刀体粘结牢固,用环氧树脂粘结,配方为6001环氧树脂115克,乙二胺6.92克,
This reamer (see picture) is used for reaming small holes in materials such as high-strength heat-resistant alloys. Its characteristics are: 1. The tooth material is YW2 cemented carbide, and the body material is 9 CrSi. The leading part of the tool has a size of 0.5 × 45 ° and a main cutting edge of 1 × 18 °. The length of the correction part is 10 mm and is made into a reverse taper. 2. With a straight blade, the chip flute is 15 ° spiral groove, mounted blade 15 ° chute slot. In order to ensure the blade and the knife body firmly bonded with epoxy resin bonding formula is 115 grams of 6001 epoxy resin, ethylenediamine 6.92 grams,
