摘要： A grinding wheel is for use in a grinding machine, and is attached on a wheel spindle of the grinding machine for simultaneously grinding at least two parts of a workpiece. The grinding wheel includes at least two wheel cores. Each of wheel cores has a disk-like shape. An abrasive layer is disposed on a circumferential surface of each of the wheel cores. A spacer portion is inseparably fixed on at least one of the wheel cores for keeping a space between the abrasive layers of the wheel cores. And a first labyrinth portion located on one of side surfaces of one of the wheel cores for forming a labyrinth seal with a second labyrinth portion arranged on the grinding machine. The number of separable parts of the grinding wheel are extremely decreased in consideration of imbalance of every part. The spacer portion is integral with at least one of the wheel cores. Since the grinding wheel is easily accurately balanced, vibration of the grinding wheel is decreased and stability is enhanced when the wheel spindle is driven at very high speed. As a result, machining accuracy for grinding is enhanced.
摘要翻译： 砂轮用于研磨机，并且被安装在研磨机的砂轮轴上，用于同时研磨工件的至少两个部分。 砂轮包括至少两个轮芯。 每个轮芯具有盘状形状。 研磨层设置在每个轮芯的圆周表面上。 间隔件部分不可分离地固定在至少一个轮芯上，用于保持轮芯的磨料层之间的空间。 以及位于一个轮芯的一个侧表面上的第一迷宫部分，用于形成迷宫式密封件，其具有布置在研磨机上的第二迷宫部分。 考虑到每个部件的不平衡，砂轮的可分离部件的数量极大地减少。 间隔部分与至少一个轮芯一体。 由于砂轮容易准确地平衡，所以当以非常高的速度驱动砂轮主轴时，砂轮的振动减小，稳定性提高。 结果，提高了研磨的加工精度。
