Truing of Super-abrasive Wheels for Form-grinding

Abstract

Diamond or CBN wheels are widely used now, but the application of these wheels in formgrinding is still limited due to the difficulty of truing. The subject of study is to achieve the technology of truing super-abrasive wheels for the form-grinding. In the present paper, a new technique using a cup-type GC wheel is proposed, and the truing device is designed and produced. This device can true a wheel into any convex shape, through envelope of lines made by the cup-type GC truer. The fundamental characteristics including truing efficiency and accuracy are also investigated by truing a CBN grinding wheel. The excellent truing performance of this device is demonstrated by grinding following truing.
