Title:
PROCESS OF MANUFACTURE RING-SHAPED COMPONENT AND MANUFACTURING APPARATUS
Document Type and Number:
Japanese Patent JP2019070443
Kind Code:
A
Abstract:
To provide a process of manufacture ring-shaped component suitable for large item small scale production by supplying the ring-shaped component at a short time.SOLUTION: A process of manufacture ring-shaped component comprises: an inside cutting process in that a first cutting blade is moved in a radial direction D4 from the state of being applied to the thickness center of one end 91a of the rotating cylindrical material 91, and is moved in the axial direction D1 to the other end 91b side and cut the inner periphery R1 side of the cylindrical material 91; an outside cutting process in that before, after or simultaneously of the inside cutting process, a second cutting blade is moved in the radial direction D4 from the state of being applied to the thickness center of one end 91a of the rotating cylindrical material 91, and is moved in the axial direction D1 to the other end 91b side and cut the outer periphery R2 side of the cylindrical material 91; and a separation process in that after the inside cutting process and the outside cutting process, a portion 92 of the cylindrical material 91 cut from the inner periphery R1 side and the outer periphery R2 side is cut-off from the remaining portion 93 of the cylindrical material 91 to obtain the ring-shaped component 94 having a substantially circular cross section.SELECTED DRAWING: Figure 6
