  • Method for forming hole-processed cast, cast casing, and screw compressor casing
    Patent number: 10352323
    Abstract: A method for forming drilled cast which includes drilling with a drill so as to provide communication with a cast hole includes a casting step and a drilling step. The casting step is to cast a cast having a cast hole which includes a flat inner wall surface in which width of a position to be drilled with the drill is obtained by adding first length H1 serving as a manufacturing error range of the cast to a diameter D of the drill, which is a second length H2. The drilling step is to form a through hole providing communication between an interior of the cast hole and an exterior of the cast through the flat inner wall surface with the drill.
