Izikulufu ezincane zilukwe ezimpilweni zethu. Abanye abantu bangase bakuphike lokhu, kodwa sisebenzisa izinto ezinezikulufu kuzo nsuku zonke. Kusukela kuzikulufu ezincane kuma-smart phone kuya kwizixhumi ezindizeni nasemikhunjini, sijabulela ukunethezeka kwezikulufu ngaso sonke isikhathi. Khona-ke kuyadingeka ukuthi sazi ukungena nokuphuma kokuthuthukiswa kwesikulufu.
Imvelaphi eyinhloko
Izikulufu ziwumkhiqizo womphakathi wezimboni. Kunzima ukulandelela ukusungulwa kwesikulufu sokuqala namuhla, kodwa izikulufu zensimbi zazisetshenziswa njengezibophelelo eYurophu okungenani ngekhulu le-15. Kodwa ngaleso sikhathi, inqubo yokukhiqiza izikulufo yayiyinkimbinkimbi kakhulu futhi ibiza, ngakho-ke izikulufa zazingavamile kakhulu futhi zingasetshenziswa kakhulu.
Intuthuko enkulu
Ekupheleni kwekhulu le-18, kwenziwa intuthuko enkulu ekukhiqizeni nasekusetshenzisweni kwezikulufu. Ngo-1770, umenzi wezinsimbi u-Jesse Ramsden wasungula i-screw lathe yokuqala, eyakhuthaza ukusungulwa komshini oyisikulufa. Ngo-1797, uMaudsley wasungula i-all-metal precision screw lathe. Ngonyaka olandelayo, uWilkinson wasungula umshini wokwenza amantongomane namabhawodi. Ngalesi sikhathi, izikulufi zazithandwa kakhulu njengendlela yokulungisa, ngoba kwakutholwe indlela engabizi yokukhiqiza.
Ukuthuthukiswa kwesikhathi eside
Ngekhulu lama-20, kwavela izinhlobo ezahlukene zamakhanda ezikulufa. Ngo-1908, isikulufu se-Robertson esinekhanda eliyisikwele sathandwa ngenxa yezindawo zaso zokulwa nokushelela ngesikhathi sokufakwa. Ngo-1936, i-Phillips head screw yasungulwa futhi yanikezwa ilungelo lobunikazi. Yayiqinile futhi iqinile kunesikulufu sikaRobertson.
Ngemuva kwekhulu lama-21, izinhlobo zezikulufi zihlukahluka kakhulu futhi uhlelo lokusebenza luhle kakhulu. Izikulufu ezihlukene zizosetshenziselwa izimo ezihlukene, njengezindlu, izimoto, amabhuloho, njll., kanye nezinto ezihlukile ezifana nensimbi, ukhuni, i-drywall, njll. Ukwelashwa kokushisa nokuphathwa kwendawo yezikulufu nakho kuyathuthuka.
Uma udinga izikulufo noma izixhumi ngokwezifiso, sinakho okufunayo. U-Fasto uneminyaka engu-20 yesipiliyoni sokukhiqiza nokudayisa izinsimbi. Sizokunikeza isevisi egculisayo.
