  • Method for manufacturing sintered component, sintered component, and drill
    Patent number: 11325186
    Abstract: Provided is a method for manufacturing a sintered component, which can suppress occurrence of edge chipping when a through-hole is formed in a powder-compact green body and also has a good productivity. The method for manufacturing a sintered component includes a molding step of press-molding a raw material powder containing a metal powder and thus fabricating a powder-compact green body; a drilling step of forming a hole in the powder-compact green body using a drill; a sintering step of sintering the powder-compact green body after drilling, wherein the drill used for drilling has a circular-arc shaped cutting edge on a point portion thereof.
    Type: Grant
    Filed: December 8, 2015
    Date of Patent: May 10, 2022
    Assignees: Sumitomo Electric Sintered Alloy, Ltd., Nikken Tool Co., Ltd.
    Inventors: Yasunori Sonoda, Ryota Take, Fumihiro Matsumoto, Tsuguru Sugimoto
