砥石を徐々に下降させていた。2. Description of the Related Art A pair of upper and lower grinding wheels having a vertical axis,
The workpiece carrier was installed concentrically and spaced apart from each other, and passed between the upper and lower whetstones. The workpiece carrier has a disk that holds a large number of short columnar workpieces with their axes vertically aligned, and is rotated by a vertically oriented drive shaft. Then, in a posture in which the disk extends in a horizontal plane, a halfway portion of the radius of the disk enters between the upper and lower grinding wheels. Then, the length (height) of the workpiece was continuously measured by the sizing device, and when the value was larger than the set value, the upper whetstone was gradually lowered by an electric signal from the sizing device. .

砥石２の上昇が止まる。The raising control of the lower grindstone 2 according to the present invention is performed as follows. The lower surface of the workpiece A coming out from between the upper and lower grinding wheels 1 and 2 is positioned lower than the set value due to the wear of the lower grinding wheel 2. At this time, the lower surface of the workpiece A hits the upper inclined surface 13a of the contact plate 13 and lowers it. A voltage corresponding to the descending amount is generated from the differential transformer of the displacement sensor 5, and this voltage signal is sent to an elevation servomotor (not shown) of the lower grindstone 2. The lower grindstone 2 gradually keeps rising at the same constant speed until this signal falls within the set value range. When the height of the lower surface of the workpiece A reaches the set value, the displacement sensor 5 does not lower the contact plate 13 even if the workpiece A comes out of the lower grindstone 2 or lowers the contact plate 13 slightly. Becomes within the set value range, and the lowering wheel 2 stops rising.
