    摘要： A circular or non-circular workpiece is ground in a plurality of grinding steps, including a final finish grinding step. A grinding wheel is caused to effect profile generation movement in synchronism with rotation of the workpiece and in accordance with profile data derived from the target shape of the workpiece. In each grinding step, the grinding wheel is advanced in such a manner that the grinding wheel causes cut-in movement within a predetermined cut-in angle defined on the workpiece. After completion of the final finish grinding step, the grinding wheel is retracted over a predetermined back-off angle defined on the workpiece. The retraction is effected in accordance with composite data obtained through combining the profile data and back-off data. The back-off angle is greater than the cut-in angle employed during the final finish grinding step.

    摘要： The present invention supplies coolant to a grinding wheel surface and reliably guides the coolant to a grinding point on the grinding wheel surface, thereby significantly reducing the amount of coolant to be used.
    In a grinding method and device for supplying coolant while grinding a workpiece W with a rotating grinding wheel 1, a fluid nozzle 2 is disposed upstream from a grinding point 11 on the circumferential surface 10 of the grinding wheel 1. The fluid nozzle 2 blows a jet of fluid across an air layer 12, which is a layer of flowing air dragged along the circumferential surface 10 of the grinding wheel 1, from one lateral side of the air layer 12 to the other lateral side of the air layer 12. A grinding fluid nozzle 3 is supplies coolant to a region between the grinding point 11 and a cutoff position 13 at which the fluid jet from the fluid nozzle 2 has deflected the air flow from the air layer 12. The coolant supplied from the grinding fluid nozzle 3 contacts the grinding point 11 on the grinding surface 10.

    摘要： A grinding wheel (G) for grinding a workpiece (W) has a first grinding surface (30) and a second grinding surface (31) successive thereto. The first and second grinding surfaces are parallel to and inclined with respect to the rotational axis (O s ) of the workpiece (W), respectively. A diameter of the workpiece (W) to be ground in a next grinding operation is measured in advance. An angle (ϑ) to be formed between the second grinding surface (31) and the rotational axis (O s ) of the workpiece (W) is selected based upon the measured diameter (d) of the workpiece (W). The selected angle (ϑ) is established between the second grinding surface (31) and the rotational axis (O s ) of the workpiece (W), in which situation. The grinding wheel (G) is moved relative to the workpiece (W) in a direction of the rotational axis (O s ) of the workpiece (W), whereby the cylindrical surface of the workpiece (W) is firstly ground by the second grinding surface (31) and subsequently ground by the first grinding surface (30) of the grinding wheel (G).
