Development of high performance grinding stone using electrophoresis deposition

传统的砂轮由磨粒、粘结剂和磨尖袋组成。大多数磨石主要考虑的是加工能力。其余的人只考虑润滑的功能。因此，需要一种没有微胶囊等上述元件的砂轮新元件。微胶囊的分散性为精密砂轮的制造提供了有利条件。采用原位聚合的方法研制了含全氟聚醚油（PFPE油）的微胶囊研磨石。PFPE油在磨削点周围高压高温下会产生摩擦化学反应。PFPE油的摩擦化学反应使软质材料变脆，使铝合金和硅片的可加工性变好。这种微胶囊研磨石为我们提供了高精度、高效率、高性能研磨的可能性。

Conventional grinding wheel is consists of abrasive grain, binder, and tip pocket. The majority of grinding stone are mainly considering the ability of machining. The rest of then are considering only the function of lubrication. Therefore the new element of grinding wheel without above element like microcapsule is needed. The dispersiveness of Microcapsule has advantages to manufacture Precision grinding wheel.Lapping stone with Microcapsule including perfluoropolyether oil (PFPE oil) was developed by "In-Situ" polymerzation in this research. PFPE oil can bring about tribochemical reaction under high pressure and high temperature around grinding point. The tribochemical reaction related with PFPE oil that changes the soft material to brittle can make machinability of aluminum alloy and silicon wafer better.This lapping stone with microcapsule gives us possibilities of high accuracy, high efficiency, and high performance grinding.
