Uhlolojikelele lwezinsimbi zokusika zamahhala
Izinsimbi zokusika zamahhala ezaziwa nangokuthi izinsimbi zomshini zamahhala yilezo zinsimbi ezakha ama-chips amancane uma zisebenza ngomshini. Lokhu kukhulisa ukusebenza kahle kwezinto ngokuhlephula ama-chips abe yizicucu ezincane, ngaleyo ndlela kugweme ukugxambukela emishinini. Lokhu kuvumela ukusebenza okuzenzakalelayo kwesisetshenziswa ngaphandle kokuxhumana komuntu. Izinsimbi zokusika zamahhala ezinomthofu nazo zivumela amazinga aphezulu omshini. Njengomthetho wesithupha, insimbi yokusika mahhala ngokuvamile ibiza u-15 % kuya ku-20 % ngaphezu kwensimbi evamile. Kodwa-ke lokhu kwenziwa ukwanda kwesivinini somshini, ukusikeka okukhudlwana, nempilo ende yamathuluzi.
Insimbi yokusika yamahhala okuyinsimbi ye-alloy yengezwe inani elithile lesulfure, i-phosphorus, i-lead, i-calcium, i-selenium, i-tellurium nezinye izakhi ukuze kuthuthukiswe ukusebenza kahle. Njengoba ukuthuthukiswa kobuchwepheshe bemishini, izidingo ze-machinability zensimbi zibaluleke nakakhulu. Kunomthelela omkhulu embonini.
Izicelo zensimbi yokusika yamahhala
Lezi zinsimbi zisetshenziselwa ukukhiqiza ama-ekseli, amabhawodi, izikulufu, amantongomane, imishayo ekhethekile, izinduku zokuxhuma, izinsimbi ezincane neziphakathi, izintambo ezibandayo nezinduku, ama-rotor aqinile, i-rotor kanye ne-gear shaft, izikhali, isitoko sikakhiye, izimfoloko namabhawodi okusetshenzwa kulengwa. isikulufu, iziqeshana zasentwasahlobo, amashubhu, amapayipi, ama-rails anesisindo esincane, ukuqinisa ukhonkolo njll.
