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.

磨轮的加工是与磨削过程有关的重要研究问题。在这项研究中，通过使用胶结的碳化物，烧结的CBN和烧结的钻石单点切割工具，对白色氧化铝研磨轮进行转弯实验，直径为100mm，长度为40mm，长度为30至150m min/min/min/min/min/min/min，最大的切割速度为1.0mm和0.20.8mmmm，因此，在各种切割条件下测量了工具磨损和切割力，并获得了最佳的工作条件。速度，进料，耙角和接近角的影响进行了专门研究。还通过低速正交切割实验，FFT分析以及静态剪切和压缩测试研究了切割机制。从这项研究中可以明显看出，可以使用合适的切割工具（例如K01，CBN或钻石）轻松切割磨牙，并选择相对较低的切割速度，大的负耙角和大型工具尖端半径。
