Ngesikhathi kwenzeka ukwehluleka, imbangela isuke igqitshwe ekujuleni kangangoba kuvame ukusolwa 'kumabherethi amabi' noma 'ukuguga okujwayelekile,' esikhundleni sephutha lokuqondanisa elikuqale konke.

Ukudlidliza: The Silent Spindle Killer

Onjiniyela bayakuthokozela kakhulu ukudlidliza ngoba kokubili kuwuphawu futhi kuyimbangela yayo yonke imodi yokuhluleka kokuphotha. Ukufaka nokungaqondi kahle ngendlela engafanele kuphakathi kwezindlela ezisheshayo zokwethula ukudlidliza ohlelweni olwaklanyelwe ukusebenza kahle.

Uma ukudlidliza sekukhona, kukhulisa zonke ezinye izinkinga. Ukuthwala ukukhathala kuyashesha, izinto zokubopha ziyaxega, ukuphila kwamathuluzi kuyehla, futhi ukuqedwa kwendawo kuyawohloka. Amafilimu okugcoba aba nokungazinzi, aguqule othintana naye abe oslayidayo. Ukushisa kuyenyuka, ukuvuleka kuyashintsha, futhi i-spindle kancane kancane ilahlekelwa ukunemba kwayo.

Ingozi yangempela ukujwayela. Ama-opharetha ayawujwayela umsindo. Amaqembu okunakekela amukela ukudlidliza 'njengokuthi lo mshini ubulokhu unjani.' Ngokombono wonjiniyela, lesi yisigaba esesabisa kakhulu—ngoba ngesikhathi ukudlidliza kuzwakala kuyinto evamile, ukwehluleka kakade kuyaqhubeka.

Ukufaka nokuqondanisa okufanele akuzona izinqubo ezingcono ozikhethele zona; ziyizidingo eziyisisekelo zokusinda kwe-spindle. Uma kwenziwa ngendlela efanele, i-spindle isebenza ngokuthula, ngokushelelayo, nangokubikezela. Uma kwenziwa kabi, abukho ubungcweti bomklamo obungawulondoloza.

Ukwesaba 7: Ukungazinaki Izimpawu Zokuqala Eziyisixwayiso

Amafulegi Abomvu Womsindo, Ukushisa, Nokudlidliza

Ama-spindle awavamile ukuhluleka ngaphandle kwesixwayiso. Esikhathini eside ngaphambi kokuba kwenzeke umonakalo omkhulu, kuba nezimpawu—izinguquko ezincane, ezichithwa kalula onjiniyela abanolwazi abazibona ngokushesha. Ukushintsha kancane komsindo ngesikhathi sokusheshisa. Izinga lokushisa elikhuphuka ngaphezu kokujwayelekile ngemva kwesikhathi eside. Ukudlidliza okuncane obekungekho ngenyanga edlule. Lokhu akukona ukuqondana; bayizinduku zokuphotha ezikhuluma ngosizi.

Onjiniyela baqeqeshelwe ukulalela imishini, hhayi nje ukuyikala. Bayazi ukuthi i-spindle enempilo izwakala kanjani nokuthi iziphatha kanjani ngesivinini esihlukene kanye nemithwalo. Lapho lawo maphethini eshintsha, ngisho nangobuqili, kuphakamisa ukukhathazeka ngokushesha. Umsindo, ukushisa, nokudlidliza yizinkomba zokuqala ezintathu ezinokwethenjelwa kakhulu zokuthi okuthile okungaphakathi kwe-spindle akusasebenzi ngendlela eklanywe ngayo.

Okupholisa umgogodla kanjiniyela amagama avame ukusetshenziswa amakhasimende ukuze alahle lezi zimpawu: 'Kuhlale kuzwakala kanjalo,' noma 'Sekuyiminyaka kushisa.' Ngokombono wobunjiniyela, lezo zitatimende ngokuvamile zisho ukuthi izimpawu eziyisixwayiso azinakwa isikhathi eside ngokwanele ukuba umonakalo omkhulu wangaphakathi ube usuqhubeka.

Okwenza Abaqhubi Benze Ukuziphatha Okungavamile

Abantu banekhono elimangalisayo lokuzivumelanisa nezimo, futhi ezindaweni zomshini, lelo khono lingaba yingozi. Ama-opharetha asebenza ngemishini efanayo nsuku zonke. Ukushintsha kancane kancane kumsindo, izinga lokushisa, noma ukudlidliza kwenzeka kancane kangangokuthi kuhlangana ngemuva. Okwake kwabangela ukukhathazeka ekugcineni kuzwakala kujwayelekile.

Onjiniyela bayakwesaba lokhu kujwayelekile ngoba kususa ukuphuthuma ezinkingeni ezidinga ukunakwa ngokushesha. I-spindle eba phezulu kancane inyanga ngayinye ayibangeli ama-alamu, kodwa ngaphakathi, izindawo ezithwele ziyawohloka futhi ukulayisha kuqala kuphuma ngaphandle kokucaciswa. Ngesikhathi ushintsho lubonakala, umonakalo ngokuvamile awulungiseki.

Lokhu akubona ubudedengu—isayensi yokusebenza kwengqondo. Ingcindezi yokukhiqiza, amashejuli aqinile, kanye nesifiso sokugwema isikhathi sokuphumula konke kukhuthaza abaqhubi ukuthi baqhubeke nokusebenza inqobo nje uma umshini usakhiqiza izingxenye. Onjiniyela bayakuqonda lokhu kucindezela, kodwa futhi bayazi ukuthi ukuziba izimpawu eziyisixwayiso zangaphambi kwesikhathi akuyiqedi inkinga. Ihlehlisa kuphela, kuyilapho inyusa kakhulu izindleko ekugcineni.

Izindleko 'Ukuyiqhuba Ize Yehluleke'

Ngokombono wobunjiniyela, 'yiqhube ize yehluleke' ingelinye lamasu okulungisa abiza kakhulu angenzeka. Lapho i-spindle ihluleka ngendlela eyinhlekelele, ayivamile ukwenza kanjalo yodwa. Ama-bearings ayabanjwa, ama-shafts score, izindlu ziyawohloka, futhi imfucumfucu isakazeka kuyo yonke i-spindle futhi kwesinye isikhathi ingene emshinini uqobo.

Umonakalo uvame ukudlulela ngale kwe-spindle. Abanikazi bamathuluzi bonakele. Ama-workpieces alahliwe. Izinto zokulungisa zonakele. Ezimweni ezimbi kakhulu, ukwakheka komshini noma uhlelo lokushayela luba nomonakalo wokubambisa. Okungase kube ukushintshwa okuhleliwe okuhleliwe noma isheke lokuqondanisa kuphenduka isikhathi sokuphumula esingahleliwe, ukulungiswa okuphuthumayo, nokulahleka kokukhiqiza.

Onjiniyela bayazi ukuthi ukungenelela kusenesikhathi konga imali, isikhathi nokucindezeleka. Ukubhekana nomsindo, ukushisa, noma ukudlidliza kuphawu lokuqala ngokuvamile kusho ukulungiswa okuncane esikhundleni sokushintshwa okugcwele. Inselele ukukholisa amakhasimende ukuthi ukumisa umshini kusenesikhathi akukona ukwehluleka—kuyisinqumo esihlakaniphile.

Kunjiniyela, ukwehluleka okukhungathekisa kakhulu yilokho obekungagwemeka ngokusobala. Izimpawu eziyisixwayiso zazilapho. Iphinifa lalicela usizo. Akulalelwanga nje ngokuhamba kwesikhathi.

Hlonipha iSpindle, Hlonipha umshini

Ngemva kweminyaka engu-20 kubunjiniyela, ukwesaba okukhulu akukhona ukuxaka, ubuchwepheshe obuthuthukisiwe, noma izinhlelo zokusebenza ezinzima—ukusetshenziswa kabi. Imishini yokuphotha yesimanje iyimpumelelo emangalisayo yobunjiniyela obunembayo. Bahlanganisa ukubekezelelwa kwezinga le-micron, ama-bearings afaniswe ngokucophelela, amasistimu okugcoba athuthukisiwe, kanye neminyaka yokuthuthukiswa komklamo. Kodwa kungakhathaliseki ukuthi zithuthuke kangakanani, izinsimbi zokuphotha azinakonakala.

Ukwehluleka okuningi kokuphotha akuwona umphumela wokuklama okungalungile noma amaphutha okukhiqiza. Ziwumphumela wokungaqondi kahle, izinqamuleli ezithathwe ngaphansi kwengcindezi yokukhiqiza, kanye nezinqumo ezenziwe ngaphandle kokucutshungulwa ngokugcwele kwemikhawulo ebonakalayo yesistimu. Ukucindezela imithwalo ephezulu, ukusebenza ngesivinini esingalungile, ukuziba izinqubo zokufaka, noma ukucashisa izimpawu eziyisixwayiso zangaphambi kwesikhathi kungase kugcine ukukhiqiza kuqhubeka namuhla—kodwa buthule baboleka isikhathi kukusasa le-spindle.

Ukuhlonipha i-spindle kusho ukuhlonipha i-physics. Kusho ukuqonda ukuthi umthwalo, isivinini, ukuthambisa, ukuqondanisa, nokudlidliza akuzona iziphakamiso—kuyizimfuneko. Kusho ukulandela izinqubo ezifanele zokufaka nokulungisa, ukukhetha amapharamitha okusebenza ngamabomu, nokuphendula ngokushesha lapho okuthile kungezwakali kahle.

Lapho amakhasimende nonjiniyela besebenza ndawonye—babelana ngolwazi, behlonipha inhloso yokuklama, nokwenza izinqumo ezinolwazi—ama-spindle aletha ukusebenza okumangalisayo, ukunemba, nokuphila isikhathi eside. Agijima epholile, ethule, futhi enokwethenjelwa. Isikhathi sokuphumula siyancipha. Izindleko zizinza. Ukuthembela emshinini kuyakhula.

Lapho lobo budlelwano bubhidlika, nokho, ngisho nemiklamo engcono kakhulu yokuphotha igcina ingaphumeleli. Hhayi ngokuzumayo, hhayi ngokuphawulekayo—kodwa ngokubikezela.

I-spindle ehlonishwayo izoklomelisa ngeminyaka yenkonzo ethembekile. I-spindle enganakwa iyohlala iqoqa izindleko zayo ekugcineni.
