Study on Characteristics of Two Phase Flow Field in Grinding Zone of Large Spiral Angle Groove Wheel

Aiming at the high specific removal energy and heat generation rate in grinding process, low transfer efficiency arc zone of ordinary wheel, problems local temperature burn are easy to occur. In this paper, plane grooving wheel with large spiral Angle is taken as research object, numerical analysis model gas-liquid two-phase flow field wedge established. The enhancement mechanism performance groove was investigated. results show that fluid into will be hindered by airflow around resulting backflow side leakage. Compared wheels without grooves, drainage big grooves significantly reduced, a amount transported exchange channel. has good conduction effect on fluid, easier enter zone, thus improving effectively reducing during process.
