The machining of grinding wheel is an important research problem related to grinding finishing process. In this study, the turning experiment was performed on white alumina grinding wheels, Hose size is 100mm in diameter and 40mm in length, by the use of cemented carbide, sintered CBN, and sintered diamond single point cutting tools, The cutting speed ranged from 30 to 150m/min, the maximum depth of cut was 1.0mm, and the feed was 0.2 to 0.8mm/rev. Thus, the tool wear and cutting force were measured for various cutting conditions, and the optimum operating condition was obtained. The effects of speed, feed, rake angle, and approach angle were specially investigated. The cutting mechanism was also studied by means of a low speed orthogonal cutting experiment, FFT analysis, and static shear and compression tests. It is evident from this study that grinding wheel can be cut easily by using a proper cutting tool, such as K01, CBN, or diamond, and by selecting relatively low cutting speeds, large negative rake angle, and large tool tip radius.

砂轮加工是磨削精加工工艺相关的一个重要研究问题。本研究在白刚玉砂轮上进行车削实验，软管尺寸为直径100mm，长度40mm，采用硬质合金、烧结CBN、烧结金刚石单点切削刀具，切削速度范围为30至150m/min，最大切削深度为1.0mm，进给量为0.2至0.8mm/rev。因此，测量了各种切削条件下的刀具磨损和切削力，并获得了最佳操作条件。特别研究了速度、进给、前角和接近角的影响。还通过低速正交切削实验、FFT分析以及静态剪切和压缩试验研究了切削机理。从这项研究中可以看出，通过使用合适的切削刀具，如K01、CBN或金刚石，并选择相对较低的切削速度、较大的负前角和较大的刀尖半径，可以很容易地切削砂轮。
