绪论 磨具的一项重要特性是他的自锐性,即磨具在工作过程中不断恢复切削能力的性能。 由于工作规范和工序的具体条件不同,磨具的这一性能也不同。例如,砂轮(砂瓦)圆周速度,加工工件速度,冷却、进刀量、加工工件的形状,材料和硬度等配合得不同,同一个砂轮的自锐性也就表现得不同 Introduction An important feature of abrasive tools is his self-sharpening, the ability of a grinding tool to continuously recover cutting power during work. Due to different work practices and the specific conditions of the process, the performance of abrasive is also different. For example, the grinding wheel (sand tile) circumferential speed, the processing speed of the workpiece, cooling, feed rate, the shape of the workpiece, hardness and other materials are different with the same self-sharpening wheel also behave differently
