A method and apparatus (100) for grinding a surface (104) on a workpiece (102), such as a spignot on a pipe, while supporting the workpiece (102) on the surface being ground (104). The grinding apparatus (100) includes workpiece support wheels (120, 121, 122). The grinding apparatus also includes a rotator mechanism (130). The grinding apparatus further includes a surface grinding mechanism (150). A cutter mechanism (150) is adjustable in a vertical direction and angularly to grind an angled surface. The grinding surface of the workpiece is maintained in contact with the two workpiece support wheels (120, 121, 122) so that the workpiece (102) self-feeds towards the surface grinding mechanism. The grinding apparatus (100) can also include an end workpiece support (140), a top workpiece support (146), a measuring device (148), and an adjustment control mechanism (184).
