Izikulufu ezincane zihlangene nempilo yethu. Abanye bangase bakuphike, kodwa sisebenzisa izinto ezinezikulufu nsuku zonke. Kusukela kuzikulufu ezincane kuma-smartphones kuya kuzixhumi ezindizeni nasemikhunjini, sijabulela ukunethezeka esilethwa ngezikulufu ngaso sonke isikhathi. Khona-ke, kuyadingeka ukuthi siqonde ukungena nokuphuma kokuthuthukiswa kwesikulufu.
- Umsuka woqobo
Izikulufu ziwumkhiqizo womphakathi wezimboni. Kunzima ukulandelela ukusungulwa kwesikulufu sokuqala namuhla, kodwa okungenani ekhulwini le-15 leminyaka eYurophu, izikulufu zensimbi zazisetshenziswa njengezibophelelo. Kodwa-ke, ngaphansi kwezimo ngaleso sikhathi, inqubo yokukhiqiza izikrini yayiyinkimbinkimbi kakhulu futhi izindleko zaziphezulu, 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-lathe yokuqala yokusika isikulufu, eyakhuthaza ukusungulwa komshini wokujiya isikulufu. Ngo-1797, uMaudsley wasungula i-all-metal precision screw lathe. Ngonyaka olandelayo, uWilkinson wasungula umshini wokwenza amantongomane namabhawodi. Ngalesi sikhathi, izikulufi zazidume kakhulu njengezindlela zokulungisa, ngoba kwakutholwe indlela engabizi yokukhiqiza.
- Ukuthuthukiswa kwesikhathi eside
Ngekhulu lama-20, kwavela izinhlobo ezahlukene zamakhanda ezikulufa. Ngo-1908, isikulufu sekhanda lesikwele seRobertson sathandwa ngezimfanelo zaso ezingasheleli ngesikhathi sokufakwa. Ngo-1936, isikulufu sekhanda se-Phillips sasungulwa futhi sanelungelo lobunikazi, esihlala isikhathi eside futhi siqinile kunesikulufu se-Robertson.
Ngemuva kwekhulu lama-21, izinhlobo zezikulufi zihluke kakhulu futhi izinhlelo zokusebenza zicwengisiswe kakhulu. Izimo zokusetshenziswa ezihlukile, njengezindlu, izimoto, amabhuloho, njll., nezinto ezihlukile njengensimbi, ukhuni, i-gypsum board, njll., zizosebenzisa izikulufu ezihlukene. Inqubo yokwelashwa kokushisa kanye nokwelashwa kwendawo yezikulufi nayo ithuthuka njalo.
Uma udinga izikulufu noma izinto zokubopha ezenziwe ngezifiso, sinakho okufunayo. I-Tianjin Lituo Hardware inesipiliyoni seminyaka engu-20 ekukhiqizeni nasekuthengiseni izinto ezisheshayo, futhi sizokunikeza isevisi egculisayo.
