  • Abrasive machining assembly
    Patent number: 5718619
    Abstract: An abrasive machining assembly (10) wherein a worktable (14) is rotatably supported on a frame (12) for rotation about a table axis (A) and a plurality of platens (32) are supported on the worktable (14) with each of the platens (32) being adapted for supporting a workpiece to be machined by a machining disc (38) rotating about a tool axis (B). Each platen (32) is rotatably supported for rotation about a platen axis (C) which is radially spaced from the table axis (A) a different distance than the tool axis (B) whereby each of the platens (32) rotates about a platen axis (C) which is parallel to and offset from the tool axis (B) when positioned in the workstation.
