Method and machine for grinding a workpiece.

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 (Os) 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 ( theta ) to be formed between the second grinding surface (31) and the rotational axis (Os) of the workpiece (W) is selected based upon the measured diameter (d) of the workpiece (W). The selected angle ( theta ) is established between the second grinding surface (31) and the rotational axis (Os) 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 (Os) 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). <IMAGE>
