Abstract

In recent years, a large number of patents have been devoted to developing abrasive machining techniques that can significantly improve both finishing precision and efficiency. Among them, one patent is about the minimum quantity lubrication grinding system. The oil composition can achieve an excellent balance between misting property and inhibition of floating mist, and ensure that an adequate lubricant reaches the grinding zone between grinding wheel and workpiece for grinding by minimum quantity lubrication system. Abrasive machining is defined as a material-removing process using hard mineral grains as cutting tools. The machining technique, which adopts a grinding wheel or abrasive belt to remove materials, is the most widely applied. Other abrasive machining processes include various techniques such as honing, lapping, polishing, and abrasive jet machining. Compared with other techniques, abrasive machining can realize high tolerance, dimensional accuracy, and surface integrity. Various high-hardness materials can be machined, especially hard and brittle materials such as optical glass, ceramics, and semiconducting materials. This paper aims to review the history, current status, and future of the abrasive machining technology. The review relies on notable academic publications as well as recent patents on grinding and abrasive machining.
