摘要： A grinding wheel comprising abrasive grains, a bonding material for bonding the abrasive grains, and grain clusters of accumulated filler grains having a size smaller than the abrasive grains. The grinding wheel may be a vitrified grinding wheel, and in this case, chromium oxide having good affinity with the vitrified bonding material may be used as the filler grains.

摘要： A solid fats and oils is impregnated in an air space of a stone matrix, as lubrication particles, of a grinding stone. The fats and oils is melted out of the air space to a peripheral surface of the grinding stone to lubricate friction between the grinding stone and a workpiece and to create a space again in the air space of the stone matrix. The created space can perform to receive a cutting tip and to discharge it. The melted lubrication particles lubricate friction between the grinding stone and the workpiece to restrain a generation of heat in order to reduce a grinding resistance. As a result, it restrains a loss of grinding particles on the peripheral surface of the grinding stone to keep a high quality of the grinding characteristics of the workpiece and to extend a truing interval and a life of the grinding stone.
摘要翻译： 将固体脂肪和油浸渍在作为研磨石的润滑颗粒的石基质的空气空间中。 脂肪和油从空气空间熔化到研磨石的周边表面，以润滑研磨石和工件之间的摩擦，并在石基质的空气空间中再次产生空间。 创建的空间可以执行以接收切割尖端并将其排出。 熔融的润滑颗粒润滑磨石与工件之间的摩擦，以抑制发热，以降低耐磨性。 因此，能够抑制磨石的周面上的研磨粒子的损失，保持工件的研磨特性的高质量，并延长磨石的修整间隔和寿命。

摘要： 5 n7 A grinding machine having an angular type grinding wheel and a dressing apparatus therefor. The grinding wheel is formed with first and second grinding surfaces usable for grinding a cylindrical surface and shoulder end surface of a workpiece, respectively, and first and second reference surfaces parallel to the first and second grinding surfaces, respectively. The positions of the first and second reference surfaces and the first and second grinding surfaces are detected with touch bars before each dressing operation so as to obtain a first distance between the first grinding surface and first reference surface, and a second distance between the second grinding surface and second reference surface. After that, a first dressing amount for dressing the first grinding surface and a second dressing amount for dressing the second grinding surface are so determined that the fist distance and the second distance would have a predetermined constant relationship after dressing operation. The first grinding surface is then dressed by the first dressing amount, while the second grinding surface is dressed by the second dressing amount.
摘要翻译： 一种具有角型砂轮的研磨机及其修整装置。 砂轮分别形成有分别用于研磨工件的圆柱形表面和胎肩端面的第一和第二磨削表面以及平行于第一和第二磨削表面的第一和第二参考表面。 在每次修整操作之前，用触摸杆检测第一和第二参考表面和第一和第二研磨表面的位置，以便获得第一研磨表面和第一参考表面之间的第一距离，以及第二研磨之间的第二距离 表面和第二参考面。 之后，确定用于修整第一研磨表面的第一修整量和用于修整第二研磨表面的第二修整量，使得在修整操作之后第一距离和第二距离将具有预定的恒定关系。 然后通过第一敷料量对第一研磨表面进行修整，同时通过第二敷料量来修整第二研磨表面。

摘要： A grinding wheel 10 comprises a disk core 11 and a grinding stone 20 surrounding the core 11. The grinding stone 20 includes a first abrasive portion 30 and a second abrasive portion 40. The first abrasive portion forms a circumferential surface of the grinding stone 20 and has small grains. The second abrasive portion 40 forms at least one lateral surface of the grinding stone 20 and has larger grains than the first abrasive portion 30.
