Abstract

A CNC cylindrical grinding machine comprising a bed, a worktable movable relative to the bed along a linear path, wheelhead movable in a direction generally perpendicular to the direction of worktable travel, a rotatable grinding wheel mounted thereon for engagement with a workpiece mounted on the worktable, wheel drive means on the wheelhead for rotating the grinding wheel, headstock and tailstock means carried by the worktable for supporting a workpiece at its opposite ends, drive means associated with the headstock and tailstock means for rotating the workpiece, worktable drive means for effecting movement of the worktable relative to the bed and therefore the wheelhead, wheelhead drive means for effecting movement of the wheelhead and therefore the grinding wheel towards and away from the workpiece, control means by which all of the drive means and particularly the worktable and wheelhead drive means, are controlled, thereby to enable the workpiece to be positioned axially and rotationally relative to the grinding wheel, and to move the grinding wheel into engagement with the workpiece, further comprising transducer means for generating position and speed of rotation signals from at least the worktable and the wheelhead, and the headstock drive, for supply to the said control means, thereby to enable complex shapes and forms to be ground in the surface of the workpiece.
