Title:
METHOD FOR MANUFACTURING GROUND WORKPIECES, AND CUP GRINDSTONE
Document Type and Number:
WIPO Patent Application WO/2018/030120
Kind Code:
A1
Abstract:
A ground workpiece having a smaller diameter than that of an object to be ground 10 is manufactured by grinding a side surface of the object to be ground 10 through the following steps (a) and (b). In step (a), a cup-type grindstone 30 is arranged such that a central axis 30a is offset from a state of being orthogonal to a central axis 10a of the object to be ground 10 to a state of being parallel thereto. In step (b), while the object to be ground 10 is axially rotated and moved in the axial direction, the cup-type grindstone 30 is axially rotated such that the cup-type grindstone 30 grinds the side surface of the object to be ground 10. By doing so, while the object to be ground 10 is roughly ground by a side surface grindstone part 36 of the cup-type grindstone 30, an outer circumferential side of the object to be ground 10 is finish cut by a bottom surface grindstone part 38 to obtain a ground workpiece.
