江苏省盐城市砂轮厂根据南京航空学院的科研成果制造的加工钛合金的新型磨具——浸渍涂层砂轮,经航天部贵州一七○厂、成都四二○厂等单位试用,证明是较为理想的钛合金磨具。钛合金是质坚韧而轻的材料。在磨削时,钛屑会迅速粘附到砂轮上,堵塞砂轮气孔,使磨削难以持续进行。浸渍涂层砂轮选用石墨和二硫化铝作为主要渗渍剂,经过浸渍涂层工艺处理,使渗渍剂牢固地粘结在磨粒表层。这样,一方面有效地防止磨粒与钛合金的直接接触,消
Yancheng City, Jiangsu Province, according to wheel grinding wheel plant in Nanjing Institute of Aeronautic Research and manufacturing of titanium alloy processing of new abrasive - dipping coating wheel, the Department of Guizhou Aerospace Department 170 plants, Chengdu 420 plants and other units proved to be more Ideal titanium alloy abrasive. Titanium is a tough, lightweight material. When grinding, titanium filings will quickly adhere to the wheel, clogging the grindstone pores, making grinding difficult to continue. Impregnated coating wheel selected graphite and aluminum disulfide as the main infiltration agent, after dipping coating process, so that the infiltration agent firmly bonded to the abrasive surface. In this way, on the one hand to effectively prevent the abrasive particles and titanium direct contact, eliminate
