めで、そのためワークの弧状外面を定圧でバフ研
摩することができなかつた。 The reason for this is that it is not equipped with a mechanism to move the buff roll along the arcuate outer surface and a mechanism to press the buff roll against the arcuate outer surface at the desired polishing pressure, so it is not possible to buff the arcuate outer surface of the workpiece at a constant pressure.
