Kuyesa m'malo otsetsereka ndi kugubuduza kukhudzana kumawoneka kuti kunali kosangalatsa ngakhale m'nthawi yakale. Mliri wa chithunzicho ndi chojambula pakhoma ku Igupto. Mwala wawukulu ukunyamulidwa mosavuta pazipila zogubuduza zomwe zaikidwa pansi pake. Momwe zipika zomwe zimagwiritsidwa ntchito zimanyamulidwira kutsogolo zikuwonetsa momwe makina ozungulira amagwirira ntchito masiku ano.
Ngakhale ma bere oyenda mozungulira amapeza komwe adachokera kale, sanagwiritsidwe ntchito ngati zida zamakina mpaka koyambirira kwa zaka za zana la 20, pomwe zozungulira zozungulira zozungulira pogwiritsa ntchito mipira yachitsulo pamayendedwe awo olondola komanso osalala adathandizira kugwiritsa ntchito makina olondola.
The Basic mechanism of rolling elementzimbalangondo zoyendainakhazikitsidwa mu 1946 pamene kampani ya ku United States, Thomson, inagulitsa mpira bushings (mtundu wokonzanso mpira). Maziko a maupangiri amasiku ano (magawo ogubuduza okhala ndi njanji) atha kuwoneka mu patent yomwe idaperekedwa ku France mu 1932. Patent iyi, ngakhale ikuphatikiza ntchito zonse zofunika za maupangiri apamizere, idayenerabe kudikirira kwazaka zambiri ntchito yawo isanayambike pamsika. Panthawiyo, zida zingapo zamakina zomwe zimagwiritsa ntchito zinthu zogudubuza monga zomangira za mpira kapena splines za mpira zidagulitsidwa. Mitundu yosiyanasiyana ya mabala a mpira (mizere yozungulira mpira) idabweretsedwanso kumsika, kuphatikiza mitundu yotseguka. Pakadali pano, zopanga zambiri ndi zokongoletsedwa zamitundu yofananira zidapangidwaotsogolera mzere.
Ife,PYG-Zhejiang Pengyin Technology Development Co., LTD, ndi bizinesi yapamwamba imayang'ana pa kafukufuku ndi chitukuko cha zigawo zofananira zotumizira zolondola komanso kapangidwe katsopano kwazaka zopitilira 20. Kuti akwaniritse zofuna zapadziko lonse lapansi, PYG ikupitiliza kukulitsa zida zopangira ndi kukonza, kuyambitsa zida zapadziko lonse lapansi zotsogola ndiukadaulo wamakono, PYG imatha kupanga misala yotsika kwambiri 0.003 mm.
