Isku dayga in lagu beddelo isdhaafsiga taabashada xidhiidhka ayaa u muuqda in lagu madadaasho xitaa da 'prhistoric. Sawirka dharbaaxo waa rinjiyeynta derbiga ee Masar. Dhagax aad u weyn ayaa loo qaadayaa si fudud oo loogu qaado diiwaanka duuban ee hoos lagu dhigay. Qaabka ay u socdaan diiwaannada hore ee dhinaca hore ayaa muujinaya sida saxda ah ee loo duubay sida muuqaalka ugu sarreeya ee farsamada wareegga ee farsamada maanta lagu soo rogay.
In kasta oo lagu duubo waxyaabaha toosan ee xijaabka ah oo dib ugu soo celiya asalkooda waqtiyadii hore, si fudud uma aysan isticmaalin inay yihiin walxaha farsamada ilaa qarnigii 20aad, marka kuwa ay kubadiyaan qarniyo toosan oo ku saabsan dhaqdhaqaaqa toosan oo toosan oo ay fududeeyaan arjiga mashiinnada saxda ah.
Habka aasaasiga ah ee sheyga la duubayMiiska toosanWaxaa la aasaasay 1946 markii shirkad Mareykan ah, Thomson, tuubbooyinka kubadaha ganacsiga (nooca dib-u-wareejinta kubbadda re-wareesan). Aasaaska hagida toosan ee maanta (cutubyo isku duuban oo leh tareenno) ayaa lagu arki karaa patent lagu siiyay Faransiiska 1932. Patent-kani, in kasta oo ay ka mid tahay dhammaan howlaha aasaasiga ah ee hagida toosan, ayaa wali ku qasbanaaday in la sugo tobanaan sano ka hor inta aan kulankiisii ugu horeysay ee suuqa lagu soo rogo. Xilligaas, dhowr qaybood oo mashiin ah oo adeegsanaya walxaha duuban sida boorarka kubadaha ama kubada kubadaha ayaa ganacsi laga dhigay. Noocyo kala duwan oo kubadaha kubadaha kubadaha ah Waqtigan xaadirka ah, wax qabadyo badan iyo hagaajinta noocyada isku midka ah ayaa loo sameeyayTilmaamaha toosan.
Annaga,Py-Zhejiang Pengding Pingyin Pringyin-ka Co., Ltd, waa shirkad tikniyoolajiyadeed oo sareysa ay diiradda saaraan cilmi-baarista iyo qaab-dhismeedka saxda ah, Pyg, Pyg wuxuu awood u leeyahay inuu wax ka beddelo taamnimada saxda ah ee saxda ah oo leh sax ahaanta 0.003 mm.
