摘要： The present invention includes an insert securably mountable within the chamber of a core drill, such as a chamfering diamond core drill used for drilling and chamfering glass articles. The insert preferably includes a first diverting facility for diverting a first portion of a lubricating/cooling fluid from within the core drill to the inner drilling surfaces of the core drill, and a second diverting facility for diverting a second portion of the lubricating/cooling fluid to the outer drilling surface and chamfering surface of the core drill, to prevent thermal damage to the article being drilled and chamfered, during both the drilling and chamfering steps. The present invention further includes a method of lubricating/cooling an article during drilling and chamfering operations with lubricating/cooling fluid from within the core drill, to prevent thermal damage to the article being drilled.
摘要翻译：本发明包括可固定地安装在芯钻的室内的插入件，例如用于钻孔和倒角玻璃制品的倒角金刚石芯钻头。插入件优选地包括第一转向设备，用于将润滑/冷却流体的第一部分从芯钻头内部转移到钻芯的内钻孔表面;以及第二转向设备，用于将第二部分的润滑/冷却流体到钻孔的外钻孔表面和倒角表面，以防止在钻孔和倒角步骤期间被钻孔和倒角的物品的热损伤。本发明还包括一种在钻孔和倒角操作期间用来自芯钻头内的润滑/冷却流体润滑/冷却物品的方法，以防止对所钻制品的热损伤。
