(under subclass 64) Abrading machine using an abrading tool the motion of which can be defined as a first movement about an axis and a second movement to-and-fro along a line.
(1) Note. In this subclass is a machine in which the active face of the tool is not necessarily or distinctively either the peripheral or the radial face and the reciprocation is other than a simple rectilinear or oscillating movement in one plane.
