…First, around 1790, H. Maudsley of England spent 10 years creating one highly accurate screw (lead screw), and established the technology to precisely replicate a second and third lead screw using a lathe attached to this as a moving screw. Meanwhile, the production of female threads, which had previously been difficult, became dramatically easier with the use of taps created by Joseph Clement (1769-1844), who worked in Maudsley's factory. It was J. Whitworth, also a student of Maudsley, who created a thread-cutting lathe that is not different from the current one, and thus established the technology for mass production of fastening screws and moving screws. … *Some of the terminology that mentions "Clement, J." is listed below.

…まず,イギリスのH.モーズレーは1790年ころ,10年がかりで1本の精度の高いねじ(親ねじ)を作り,これを運動用ねじとして取りつけた旋盤により第2,第3の親ねじを精密に複製する技術を確立した。一方,従来困難であっためねじの製作は,モーズレーの工場で働いていたクレメントJoseph Clement(1769‐1844)が作ったタップの利用により,飛躍的に容易となった。現在のものと変わらないねじ切り旋盤をつくり,これによって締結用ねじおよび運動用ねじの大量生産の技術を確立したのは,これまたモーズレーの弟子であったJ.ホイットワースである。… ※「Clement,J.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
