Title: Workpiece guide device of centerless grinding machine
Inventor: NAKAMURA TAKASHI
IPC: B24B5/307
Filed: 1989-06-15
Abstract: PURPOSE:To almost eliminate the necessity for readjusting a position of a guide plate, even when the diameter of a workpiece is changed, by tilting the guide plate in an adjusting wheel side-workpiece guide to a tilt angle corresponding to an angle of center height and setting a front surface of the guide plate, in a contact position of the workpiece with an adjusting wheel, to agree with almost the direction of a tangent of the latter. CONSTITUTION:The position of a guide plate 11 is fixed in such a manner that the periphery of a workpiece W on a blade BD almost accurately agrees with the periphery of an adjusting wheel RW. Here because the guide plate 11 is tilted by a predetermined tilt angle for a vertical surface, a front surface of the guide plate 11 agrees, in a contact position between the workpiece W and the adjusting wheel, almost with the direction of a tangent of the latter. Accordingly, when a position is adjusted and set for a workpiece W of specific diameter, the necessity for readjusting the guide plate 11 is almost eliminated only with center height H of the workpiece in a fixed value even when the workpiece W of different diameter is machined.
