Injongo yokulinganisa umbhobho wentsimbi (ukunciphisa) kubukhulu (ukunciphisa) umbhobho orhabaxa kunye nedayamitha enkulu ukuya kumbhobho wentsimbi ogqityiweyo onobubanzi obuncinci kunye nokuqinisekisa ukuba ububanzi bangaphandle kunye nobukhulu bodonga lombhobho wentsimbi kunye nokutenxa kwabo kuyahlangabezana iimfuno zobugcisa ezifanelekileyo.

Iziphene ezisemgangathweni ezibangelwa ukulinganisa umbhobho wentsimbi (ukunciphisa) ngokukodwa kubandakanya ukutenxa komlinganiselo wejometri wombhobho wentsimbi, ubukhulu (ukunciphisa) "umgca oluhlaza", "uphawu lwezikhonkwane", isiva, i-abrasion, i-pockmark, i-convexity yangaphakathi, isikwere sangaphakathi, njl.
Ukutenxa komlinganiselo wejometri wombhobho wentsimbi: Ukutenxa komlinganiselo wejometri wombhobho wentsimbi ikakhulu ubhekiselele kwidayamitha engaphandle, ubukhulu bodonga, okanye umbhoxo wombhobho wentsimbi emva kokulinganisa (ukunciphisa) ukungafezeki komlinganiselo kunye neemfuno zokutenxa ezichazwe kwimigangatho efanelekileyo.

Ngaphandle kokunyamezela kwedayamitha yangaphandle kunye ne-ovality yombhobho wentsimbi: Izizathu eziphambili zezi: i-roller engafanelekanga kunye nokulungiswa komngxuma we-size (ukunciphisa) i-mill, ukusabalalisa okungekho ngqiqweni kwe-deformation, ukuchaneka okungahambi kakuhle, okanye ukunxitywa okukhulu kokulinganisa (ukunciphisa) i-roller, iqondo lokushisa eliphezulu kakhulu okanye eliphantsi kakhulu lombhobho orhabaxa, kunye nobushushu be-axial obungalinganiyo. Ibonakaliswa ikakhulu kwimilo yomngxuma kunye nendibano ye-roller, ukucuthwa kobubanzi bombhobho orhabaxa, kunye nobushushu bobushushu bombhobho orhabaxa.

Ukunganyamezeli kobunzima bodonga lombhobho wentsimbi: Ubukhulu bodonga lombhobho orhabaxa oveliswe emva kokulinganisa (ukunciphisa) buphuma ekunyamezelweni, okubonakaliswa ngokubonakalayo njengobunzima bodonga olungalinganiyo kunye nomngxuma ongaphakathi ongeyo-circular wombhobho wentsimbi. Ichatshazelwa ikakhulu zizinto ezinjengobungqingqwa bodonga ukuchaneka kombhobho orhabaxa, ukumila komngxuma kunye nohlengahlengiso lomngxuma, uxinzelelo ngexesha lokulinganisa (ukunciphisa) ubungakanani bokunciphisa umbhobho orhabaxa wedayamitha, kunye nobushushu bobushushu bombhobho orhabaxa.

"Imigca eluhlaza okwesibhakabhaka" kunye "namanqaku eminwe" kwimibhobho yentsimbi: "Imigca eluhlaza okwesibhakabhaka" kwimibhobho yentsimbi ibangelwa ukungahambi kakuhle kweerola kwisakhelo esinye okanye ezininzi zemill yokulinganisa (ukunciphisa), okubangela ukuba uhlobo lomngxuma lungabikho " ngeenxa zonke”, ebangela ukuba umda we-roller ethile usike kumphezulu wombhobho wentsimbi ukuya kubunzulu obuthile. "Imigca eluhlaza okwesibhakabhaka" ihamba kwindawo yangaphandle yombhobho wensimbi yonke ngendlela yomgca omnye okanye ngaphezulu.

"Iimpawu zeminwe" zibangelwa ngumahluko othile kwisantya somgca phakathi komgca we-roller kunye nezinye iindawo ze-groove, ezibangela ukuba umgca we-roller unamathele kwintsimbi uze ukrwele umphezulu wepayipi yensimbi. Esi siphene sisasazwa kwicala le-longitudinal ye-tube body, kwaye i-morphology yayo i-arc emfutshane, efana nokumila kwe "fingernail", ngoko kuthiwa "uphawu lweminwe". "Imigca eluhlaza okwesibhakabhaka" kunye "namanqaku eminwe" inokubangela ukuba umbhobho wensimbi ukhutshwe xa unzima.

Ukuphelisa "imigca eluhlaza okwesibhakabhaka" kunye "namanqaku eminwe" kwiziphene kumphezulu wombhobho wensimbi, ukuqina kwe-roller yokunciphisa (ukunciphisa) kufuneka kuqinisekiswe kwaye ukupholisa kwayo kufuneka kugcinwe kakuhle. Xa uyila umngxuma roll okanye uhlengahlengiso umngxuma roll, kuyimfuneko ukuba uqinisekise umngxuma efanelekileyo icala udonga i-angle yokuvula kunye nexabiso umsantsa roll ukunqanda umngxuma ukuba ungahambi kakuhle.

Ukongezelela, umlinganiselo wokunciphisa umngxuma wefreyimu enye kufuneka ulawulwe ngokufanelekileyo ukuze ugweme ukwanda okugqithisileyo kombhobho ogqithiseleyo emngxunyeni xa uqengqeleka umbhobho ophantsi wobushushu obuphantsi, obangela ukuba isinyithi sicinezele kwi-gap yomqulu, kwaye ukonakalisa ukuthwala ngenxa yoxinzelelo olugqithileyo lokuqengqeleka. Umkhuba ubonise ukuba ukusetyenziswa kwetheknoloji yokunciphisa uxinzelelo kukulungele ukunciphisa ukwandiswa kwecala lentsimbi, esebenza kakhulu ekunciphiseni "imigca eluhlaza okwesibhakabhaka" kunye "namanqaku eminwe" yemibhobho yensimbi. Iziphene zinefuthe elihle kakhulu.

Ukuqhawuka kombhobho wentsimbi: Ukukrala kombhobho wentsimbi kusasazwa ngendlela engaqhelekanga kumphezulu womzimba wombhobho. I-scarring ikakhulu ibangelwa yintsimbi enamathele kumphezulu we-roller yokulinganisa (ukunciphisa). Inxulumene nezinto ezifana nobunzima kunye neemeko zokupholisa ze-roller, ubunzulu bohlobo lomngxuma, kunye nokulinganisa (ukunciphisa) ubungakanani bombhobho orhabaxa. Ukuphucula imathiriyeli ye-roller, ukwandisa ubulukhuni bomphezulu we-roller, ukuqinisekisa iimeko zokupholisa ze-roller ezilungileyo, ukunciphisa ubungakanani bombhobho orhabaxa (ukunciphisa), kunye nokunciphisa isantya sokutyibilika phakathi komphezulu we-roller kunye nomphezulu wesinyithi luncedo ekunciphiseni. ithuba lokuncamathela kwintsimbi. Emva kokuba umbhobho wentsimbi ufunyanwe unenxeba, isakhelo apho inxeba iveliswa khona kufuneka lifunyanwe ngokwemilo kunye nokusasazwa kwesiphene, kwaye inxalenye yerola enamathela kwintsimbi ifanele ihlolwe, isuswe okanye ilungiswe. I-roller engakwazi ukususwa okanye ukulungiswa kufuneka itshintshwe ngexesha.

Ukukrwela umbhobho wentsimbi: Ukukrwela umbhobho wentsimbi ikakhulu kubangwa “ziindlebe” phakathi komlinganiselo (ukunciphisa) izakhelo kunye nomphezulu wetyhubhu yesikhokelo sokungena okanye ityhubhu yesikhokelo sokuphuma encamathele kwintsimbi, ukuhlikihla kunye nokonakalisa umphezulu wombhobho wentsimbi oshukumayo. . Nje ukuba umphezulu wombhobho wentsimbi ukrwelwe, Khangela ityhubhu yesikhokelo yentsimbi encangathi okanye ezinye iziqhoboshelo ngexesha, okanye ususe "iindlebe" zentsimbi phakathi kokulinganisa (ukunciphisa) izakhelo zoomatshini.

Umphandle we-hemp wangaphandle wombhobho wentsimbi: Umphezulu we-hemp wangaphandle wombhobho wentsimbi ubangelwa kukunxitywa komphezulu we-roller kwaye uba rhabaxa, okanye iqondo lobushushu lombhobho orhabaxa liphezulu kakhulu, kangangokuba isikali somphezulu we-oxide singqindilili kakhulu, kodwa sithe kratya. ayisuswanga kakuhle. Phambi kokuba umbhobho orhabaxa ulinganiswe (uncitshiswe), isikali se-oxide kumphezulu ongaphandle wombhobho orhabaxa kufuneka sisuswe ngokukhawuleza nangempumelelo ngamanzi anoxinzelelo oluphezulu ukuze kuncitshiswe ukwenzeka kweziphene kumphezulu we-hemp wangaphandle wombhobho wentsimbi.

Umbhobho wentsimbi wangaphakathi: Ubunzulu obungaphakathi bombhobho wentsimbi bubhekisa kwinto yokuba xa umbhobho orhabaxa ulinganisiwe (uncitshisiwe), ngenxa yobukhulu obugqithisileyo (ukunciphisa) ubungakanani besakhelo esinye somatshini wokulinganisa (wokunciphisa), umbhobho. udonga lombhobho wensimbi lugobile ngaphakathi (ngamanye amaxesha kwimilo evaliweyo), kwaye i-defect linear ephakanyisiweyo yenziwe eludongeni lwangaphakathi lombhobho wensimbi. Esi siphene asenzeki rhoqo. Ubukhulu becala kubangelwa iimpazamo ekudityanisweni kwezakhelo zerola zomatshini wokulinganisa (ukunciphisa) okanye iimpazamo ezinzulu kwimilo yohlengahlengiso lomngxunya xa ulinganisa (ukunciphisa) imibhobho yentsimbi ebhityileyo. Okanye i-rack inokusilela komatshini. Ukwandisa i-coefficient yoxinzelelo kunokunyusa ukunciphisa okubalulekileyo kokunciphisa. Ngaphantsi kweemeko ezifanayo zokunciphisa ububanzi, inokuphepha ngokufanelekileyo ukuchasana kwangaphakathi kombhobho wensimbi. Ukunciphisa ukunciphisa ububanzi kunokuphucula ukuzinza kombhobho onqabileyo ngexesha lokuguqulwa kunye nokuthintela ngokufanelekileyo umbhobho wensimbi kwi-convex. Kwimveliso, ukudibanisa umqulu kufuneka kuqhutywe ngokungqongqo ngokuhambelana netafile eqengqelekayo, kwaye uhlobo lomngxuma we-roll kufuneka lulungiswe ngononophelo ukukhusela ukwenzeka kweziphene ze-convex kumbhobho wensimbi.

"Isikwere sangaphakathi" sombhobho wensimbi: "Isikwere sangaphakathi" sombhobho wensimbi sithetha ukuba emva kokuba umbhobho orhabaxa ulinganiswe (uncitshiswe) ngokulinganisa (ukunciphisa) i-mill, umngxuma ongaphakathi wecandelo layo elinqamlezileyo "li-square" (i-roller ezimbini). ukulinganisa kunye nokunciphisa ilitye lokusila) okanye "i-hexagonal" (i-ezintathu-roller ukulinganisa kunye nokunciphisa ilitye). "Isikwere sangaphakathi" sombhobho wensimbi siya kuchaphazela ukuchaneka kodonga lwayo kunye nokuchaneka kobubanzi bangaphakathi. I-"square yangaphakathi" yesiphako sombhobho wensimbi ihambelana nexabiso le-D / S lombhobho onqabileyo, ukunciphisa ububanzi, ukunyanzeliswa ngexesha lokulinganisa (ukunciphisa), ukubunjwa komngxuma, isantya sokujikeleza, kunye nokushisa okujikelezayo. Xa ixabiso le-D/S lombhobho orhabaxa lincinci, uxinzelelo luncinci, ukuncitshiswa kwedayamitha kukhulu, kwaye isantya sokuqengqeleka kunye nobushushu obuqengqelekayo buphezulu, umbhobho wentsimbi unokuba nobunzima obungalinganiyo bodonga olunqamlezayo, kwaye “ isikwere esingaphakathi” isiphene sibonakala ngakumbi.
