意味

切断する／切り分ける（技術的に切る）

More technical and precise than the general 切 (to cut). Commonly used in manufacturing, construction, surgery, and geology. Also used figuratively for political or territorial division: 切割利益 (to divide up interests) or 切割责任 (to separate oneself from responsibility). The figurative use is informal and somewhat negative.
