Ubume bamaqhekeza angaphezulu kunye nokubunjwa kwengubo kudlala indima ebalulekileyo ekulungelelaniseni amavili okugaya kwizicelo ezahlukeneyo.
Ukuthelekisa usetyenziso kwivili le-superabrasive elilelona lifanelekileyo kunokuzuza ngokuphucula umgangatho wenxalenye kunye nemveliso yemveliso, ukwenza ulwazi olunzulu lwegrit, ibhondi kunye neempawu zokugquma ezibaluleke kakhulu kubasebenzisi begrinder.Ifoto ngoncedo lukaWanyu Abrasives.
Ukhetho olufanelekileyo lwamavili okugaya anzima kakhulu luyimfuneko kwinkqubo yokugaya esebenzayo.Ivili elilungileyo linokwandisa iinxalenye ngeyure, ukunciphisa utshintsho lwesixhobo, ukwandisa ixesha lomatshini, ukuphucula umgangatho wemveliso kunye nokunciphisa iindleko zokusebenza.Nangona kunjalo, ukufumana ivili elinjalo kufuna ukufundisisa ngononophelo kwimilo yeenkozo kunye nokugquma kwe-supraabrasive, phakathi kwezinye iimpawu.
Superabrasive amavili okugaya asebenza phantsi kweemeko ezinzima zokusila kwaye kufuneka abe nenani leepropati, kubandakanywa ubulukhuni kumaqondo aphezulu okushisa, ukuhanjiswa okuphezulu kwe-thermal ukususa ubushushu kwi-edge yokusika, ukuzinza kokubumba, ukuxhathisa ukunxiba, ukuthambisa kunye nokumelana nokuguqulwa kweplastiki.
Ukusebenza kwevili lokugaya i-supraabrasive ngokuyinhloko kunqunywe yi-substrate edibeneyo, kunye neempawu zendalo kunye nomgangatho wengqolowa ye-abrasive yevili, ingaba yidayimane okanye i-cubic boron nitride (CBN).Iinqununu ezahlukeneyo kunye neengubo zibonelela ngamandla ahlukeneyo kwaye ngoko ke zifanelekile kwizicelo ezahlukeneyo.Ukwazi ukuba zeziphi iinqununu kunye neengubo ezifanelekileyo kwizicelo ezithile kunokugcina imali yabavelisi ngexesha.
Kuxhomekeka kwisicelo okanye inkqubo yokusila, ukutya okuziinkozo kweprimiyamu okanye ukutya okuziinkozo okuxabisa kakhulu kunokuba lolona khetho lunoqoqosho lomsebenzi.Ngokunjalo, eyona diamond ibiza kakhulu okanye amavili e-CBN ayinakulungela isicelo esinikiweyo.Eyona nto ibalulekileyo ayilona xabiso, kodwa imilo yeenkozo ezigqithisileyo kunye nohlobo lokwaleka olusetyenziswa kwivili.
Ukuqina kubhekisa ekuziphatheni kwenkozo erhabaxa phantsi koxinzelelo lomatshini, oko kukuthi, ukukwazi kwayo ukumelana nokuqhekeka, ukuqhekeka, kunye nokuqhekeka.Ubuqhophololo bubhekisa ekukwazini ukophuka kunye nokuzilola kweenkozo.
Iinkozo eziqine kakhulu ezirhabaxa zithande ukuba ngqindilili kwaye zibambe imilo yazo ngcono kunokuba zisuse izinto.Iincinci ze-brittle zilolwa ngamaxesha, imilo yazo ye-angular isusa izinto ezininzi ngokudlula nganye.Ukusetyenziswa okuhlukeneyo kufuna iinkozo kwiindawo ezahlukeneyo kwi-spectrum phakathi kwezi fom zimbini.
Ngokwefom, kukho iindidi ezimbini ze-polar: i-blocky kunye ne-angular.I-agglomerated okanye ijikelezwe ngamaqhekeza e-abrasive, iyancipha ukusika, kodwa ngcono ukubunjwa kugcinwe.Amasuntswana aqokelelweyo anamandla kwaye amelana namandla abrasive aphezulu phambi kokuba aphuke.
Ngokuchasene noko, iimilo ze-angular zinobundlobongela kwaye zingena ngcono kwaye zisuse izinto.Nangona kunjalo, iinkozo ze-angular zitshatyalaliswa ngomzamo omncinci.
Ngokufanelekileyo, kufuneka kubekho i-particle elungelelanisa le milo mibini, ivumela ukuba ihlale iqinile, ivumela ukuba iphule ngokwemvelo, ibonakalise i-edge entsha, ebukhali yokusika.Ngaphandle kokukwazi ukuqhekeka, iinkozo ziya kuba buthuntu kwaye zikhuhle ngokuchasene nomsebenzi endaweni yokusika, kubangela ukunyuka kwamandla okusila kunye neengxaki ezinzulu zevili kunye nomsebenzi.
Ukwambathisa yinkqubo yokwaleka ngokupheleleyo nangokulinganayo iinkozo superabrasive umaleko wezinto ezongezelelweyo.Le nkqubo inyusa ubungakanani bengqolowa kunye nobunzima, obuhlala busetyenziselwa ukuphucula iimpawu ezifana namandla kunye nokuqina ekusileni.
Amandla e-matrix edibeneyo yokubamba ingqolowa enqabileyo imisela ukusebenza kwevili lokusila.Inzuzo ephambili yokugquma kukuba bayakwazi ukuthungatha idayimani okanye amasuntswana e-CBN ukuze babambelele ngakumbi kwivili, nokuba yi-resin, i-vitreous, isinyithi, i-hybrid okanye enye.Ukuphuculwa kokugcinwa koomatshini kunye neekhemikhali zesixokelelwano sokudibanisa siphucula ukuthembeka kwevili.
Ukongiwa kweendleko kunye nemveliso ephezulu eza ngokukhetha ivili lokusila elilungileyo kunokuba lula ukukhuphisana ukuba iworkshop idlala amakhadi ayo ngokufanelekileyo.
I-Nickel, i-copper kunye ne-silver coatings zezona zinto ziqhelekileyo zokugquma.I-Nickel plating ixhaphakile kwi-resin bonded wheels.Ezi zogquma ziphucula ubomi bevili, ukugqiba komphezulu, ukuchithwa kobushushu kunye nokuncamathela ngoomatshini kwiindawo zokubopha ukunyusa ukusebenza.
Iingubo zobhedu ziyi-copper ekhethiweyo yokugaya okomileyo ngenxa yokukwazi ubhedu ukuqhuba ukushisa kude nommandla wokugaya kunye nokuphucula ukugcinwa kweengqungquthela zomatshini kunye neekhemikhali kwinkqubo edibeneyo.
Iingubo zesilivere zibiza kakhulu kodwa zinika i-thermal conductivity ephezulu yeentlobo ezintathu zokugquma, kunye nokugcinwa kwe-particle ephuculweyo kunye ne-lubricity eyongezelelweyo.Isilivere yeyona nto ikhethwayo xa i-oyile esulungekileyo isetyenziswa njengesipholisi.
Ubungakanani bokugquma kwiinkozo ezirhabaxa bunokusuka kwi-30% ukuya kwi-70% yobunzima bubonke benkozo egqunyiweyo.Izogquma kwiisuntswana zedayimani ziqhele ukuba ngama-50% ukuya kuma-56% ngobunzima, ngelixa amasuntswana e-CBN ahlala esetyenziselwa ukoleka kwi-60% ubunzima.Ii-superabrasives ezigqunyiweyo zikholisa ukuba zibiza kakhulu kuneebrasives ezingagqunywanga ngenxa yokusebenza kwazo okuphezulu okulindelweyo kunye namanyathelo okwenziwa awongezelelweyo afunekayo ukuze zivelise.
Nokuba uhlengahlengiso oluncinci kwi-abrasive kwivili lokugaya lunokuba lutshintsho lomdlalo kwinkqubo yakho yokugaya kunye nenkqubo.Ugcino lweendleko kunye neenzuzo zemveliso ekukhetheni ivili lokusila elilungileyo kunokuba lula ukukhuphisana ukuba iworkshop idlala amakhadi ayo ngokufanelekileyo.
Ngokusebenzisa ubuchule obuphambili, obuphezulu bokusebenza kwinkqubo yomatshini, itekhnoloji yeSolidCAM iMachining inokunciphisa kakhulu amaxesha okujikeleza kwaye yandise kakhulu ubomi besixhobo xa kuthelekiswa nokusila kwemveli.
Amandla abandakanyekayo kwinkqubo yokusila inokulinganiswa, ukuvumela izixhobo zemathematika ukuba zisetyenziswe ukuqikelela nokulawula la mandla.Iifomula ezichanekileyo zokubala ezi zixhobo zikuvumela ukuba ulungise umgangatho womsebenzi wokusila.
