Effects of truing/dressing intensity on truing/dressing efficiency and grinding performance of vitrified diamond wheels

摘要

A systematic study on truing and dressing of vitrified diamond wheels using silicon carbide and mild steel rollers was conducted. Truing/dressing intensity was introduced to evaluate the truing/dressing efficiency. Experimental results show that the truing/dressing efficiency exhibits a strong relationship with the intensity. Grinding tests were also carried out to examine the effect of the truing and dressing on the grinding performance of the wheel, particularly at higher speeds. It was found that larger dressing intensities should be applied for rough grinding whilst lower dressing intensities can be used for fine grinding in terms of the wheel topography produced and the subsequent grinding performance.
