シリカ微粒子を利用した固体潤滑法の提案(機械要素,潤滑,工作,生産管理など)

A new cutting lubrication method employing solid lubricant has been proposed for green machining. In this method, nm order silica particles were selected for the lubrication agent, referring to glass extrusion process. Glass has not only an ability to lublicate, but also it has some great advantages, for example, the strong electrostatic to manipulate its motion. Therefore paying attention to electrophoresis in particular, the lubrication method, spraying nm order silica particles under colloidal condition around cutting area and guide them to the cutting point, was tried out. The result showed the good prospect of the method, such as reduction of cutting force and burr, long tool life since glass particles promote better chip flow, and that also proved this method was efficient for environment.
