ガス通気研削加工法の開発

Abstract

Grinding has drawbacks where the attrition wear of grain deteriorates the accuracy and the quality of workpiece under the condition of high speed and high pressure. So far it has been made clear that a chemical reaction in manufacturing is the cause of the attrition wear of grain. In other words, the chemical reaction control should make possible to manufacture with the sharp grain. This study pays attention to the chemical reaction caused by grinding into steel materials with aluminum oxide grain. The purpose of this study is to reduce a chemical reaction by removing oxygen that is caused by it in the grinding point and to propose a new grinding method that maintains sharp grain on wheel surface for long time. The method used is a kind of processing method where argon gas passes through a grinding wheel. According to this method, the chemical reaction should be caused between workpiece and grain controlled, and the workpiece surface should be manufactured as good one with the sharp grain. As a result obtained it was clear that the manufacture efficiency of the new processing method was improved better in comparison with a conventional method of it. This paper shows the valuation of grinding phenomena and effect of the new processing method.
