Ukulungiswa kwentsimbi engagqwaliyo kwimizi-mveliso kunika "udonga lokusebenza" olukhulu kubasebenzi bentsimbi abaninzi kunye neengcali zokuthenga. Ngelixa intsimbi engagqwaliyo inika ukumelana nokugqwala okugqwesileyo kunye nokukhanga kobuhle, iimpawu zayo zoomatshini zenza kube nzima kakhulu ukuyitshixa. Amanqanaba aphezulu okuqina komsebenzi kunye nokuqhuba okuphantsi kobushushu kudla ngokukhokelela ekugugeni ngokukhawuleza kwezixhobo okanye ukusilela okukhulu xa kusetyenziswa izixhobo eziqhelekileyo. Olu celomngeni luhlala lubangela ingxoxo ebalulekileyo kwimarike yezixhobo zehlabathi: Ngaba i-cobalt iyimfuneko ngokwenene ekugrumbeni intsimbi engagqwaliyo ngempumelelo? Njengento eyaziwayoUmthumeli we-China Top Metal Cobalt Drill Bit, I-Jiacheng Tools iphendula lo mbuzo ngokuhlalutya indlela edibana ngayo isinyithi sezixhobo kunye nezinto zokusebenza ezixineneyo kakhulu. Ukuqonda ukuhambelana kwezinto akusiyo nje inkcukacha yobugcisa; yimfuneko ebalulekileyo kubasasazi abafuna ukubonelela ngezisombululo ezithembekileyo kwimizi-mveliso yeenqwelo-moya, iimoto, kunye nokucubungula ukutya.
Ukukhetha isixhobo esifanelekileyo kufuna ukuphonononga nzulu indlela ii-alloys ezahlukeneyo eziziphatha ngayo phantsi kobushushu obugqithisileyo kunye noxinzelelo lwendawo yokusika. Esi sikhokelo sihlola imfuneko yokusebenza kwe-cobalt ngelensi yobungcali, sibonelela ngokucaca malunga nokuba kufuneka nini kwaye kutheni ii-alloys ezikhethekileyo ukuze kugcinwe ukusebenza kakuhle kwemveliso.
Umbuzo 1: Kutheni ii-standard HSS drill bits zihlala zingaphumeleli xa zidityaniswe nentsimbi engagqwaliyo?
Ukuze uqonde ukuba kutheni iStandard High-Speed Steel (HSS) "ibetha" okanye ingaphumeleli ngexesha lokusetyenziswa kweStainless Steel, umntu kufuneka ahlolisise ifiziksi yokusika. IStainless Steel ayisebenzi kakuhle ekufudumaleni. Ngokungafaniyo neCarbon Steel, evumela ubushushu ukuba buphele kwindawo yokusebenza kunye neetships, iStainless Steel ibamba amandla obushushu kwindawo yokudibana phakathi komphetho wesixhobo kunye nesinyithi. Oku kwakheka kobushushu kwindawo ethile kunokufikelela kumaqondo obushushu angaphezulu kwama-600 degrees Celsius ngemizuzwana.
Izixhobo ze-HSS eziqhelekileyo, ezenziwe ngentsimbi ye-M2 grade, zinomda othile "wobunzima obomvu". Nje ukuba ubushushu budlule lo mkhawulo, umda ophambili uyathamba, into eyaziwa ngokuba yi-plastic deformation. I-Cobalt iyitshintsha ngokupheleleyo le khemikhali. Ngokusebenza njenge-stabilizing matrix, i-cobalt inyusa ubushushu apho intsimbi iqala ukuthamba khona.Izixhobo zeJiacheng Ingcali kwiiklasi ze-HSS M35 kunye ne-M42, apho ukongezwa kwe-cobalt kuqinisekisa ukuba i-drill bit igcina ukuqina kwayo kunye nomgca obukhali nangona indawo yokusika ikhazimla ngombala obomvu. Ngaphandle kwe-cobalt, ukungqubana okubangelwa yindalo eqinileyo, "ethambileyo" yentsimbi engagqwaliyo kuya kuyenza ingabi mnandi i-bit eqhelekileyo phantse ngoko nangoko, nto leyo ekhokelela kwiimfuno zokunyuka kwe-thrust kunye nokuqhekeka okunokwenzeka.
Umbuzo 2: Phakathi kwe-5% yeCobalt (M35) kunye ne-8% yeCobalt (M42), iingcali zifanele zikhethe njani ngokusekelwe kwiimfuno ezithile?
Ukukhethwa kwezinto akusoloko kusithiwa "okuninzi kusoloko kungcono." Endaweni yoko, kukulinganisela phakathi kobulukhuni kunye nokuqina. Abathengisi abangochwephesha bahlulahlula izixhobo ze-cobalt zibe ziiklasi ezimbini eziphambili ukuze bahlangabezane neemfuno zoshishino ezahlukeneyo. I-Jiacheng Tools ibonelela ngesakhelo sokukhetha esichanekileyo kumaqabane ayo aphesheya ukuqinisekisa ukuba isixhobo sihambelana ne-alloy ethile eyombiwayo.
Kwizintsimbi eziqinileyo ze-austenitic stainless steels, ezifana neGrade 304, i-HSS M35 (equlethe i-5% ye-cobalt) ngokubanzi lolona khetho lungabizi kakhulu kwaye lusebenza kakuhle. I-M35 inika ukwanda okukhulu kokumelana nobushushu ngaphezu kwe-M2 ngelixa igcina ukuqina okwaneleyo ukumelana nokungcangcazela kokubhola ngesandla okanye okuzenzekelayo. Nangona kunjalo, xa usetyenziso lubandakanya izixhobo ezifuna kakhulu ezifana neGrade 316, Grade 317, okanye i-Super Duplex stainless steel, ukutshintshela kwi-HSS M42 (equlethe i-8% ye-cobalt) kuba yimfuneko. I-M42 ifikelela kwi-Rockwell hardness ephezulu (HRC), ebalulekileyo kwiintsimbi ezingenela ngaphakathi ezibonisa ukuqina okugqithisileyo komsebenzi. Inzuzo kukuba i-M42 ibuthathaka kancinci kune-M35. Ke ngoko, i-M42 ifanelekile kwiindawo ze-CNC eziqinileyo nezichanekileyo apho uzinzo lomatshini lunciphisa umngcipheko wokuqhekeka ecaleni. Eli nqanaba lokwahlulahlula ngobungcali livumela abasasazi ukuba banike iingcebiso ezifanelekileyo kubathengi babo, bephucula ubomi bezixhobo kunye nohlahlo-lwabiwo mali lweprojekthi.
Umbuzo 3: Ngaphaya kokwakheka kwezinto, uyilo lwejometri luyidala njani impembelelo "yokusika okubandayo"?
Nangona i-alloy inika isiseko, uyilo lwejometri yesixhobo lusebenza njengenjini yokusebenza. Iibhithi zeCobalt drill ezenzelwe ukusebenza ngesinyithi esinzima zihlala zinenguquko ezahlukeneyo ezahlukileyo kwiibhithi zenjongo eqhelekileyo. Umzekelo oyintloko kukusetyenziswa kwenqaku lokwahlulahlula le-135-degree. Iibhithi eziqhelekileyo zihlala zinenqaku le-118-degree, elifanelekileyo kwiintsimbi ezithambileyo kodwa lidla "ngokuhamba" kumphezulu oqinileyo wentsimbi engagqwaliyo.
I-engile ye-135-degree inika iprofayili ethe tyaba edibana nommandla omphezulu ngoko nangoko, nto leyo evumela isixhobo ukuba sizibeke kwindawo yaso. Olu yilo, kunye nolwakhiwo "oluxineneyo", lonyusa ubulukhuni be-drill iyonke. I-Jiacheng Tools ikwasebenzisa ukugaywa okuchanekileyo okukhethekileyo ukuze kufezekiswe "indawo yokwahlulahlula" enciphisa ubude bomphetho we-chisel. Olu tshintsho lunciphisa kakhulu ukutyhala kwe-axial okufunekayo ukungena kwizinto. Ngokunciphisa amandla afunekayo ukusika, isixhobo sivelisa ukungqubana okuncinci, kwaye ngenxa yoko, ubushushu obuncinci. Olu nxibelelwano phakathi kwe-M35/M42 metallurgy kunye ne-geometry ephucukileyo ludala oko iinjineli zikubiza ngokuba yi-"cold cutting effect", apho isixhobo sihlala sizinzile kwaye umsebenzi uhlala ungonakaliswanga luxinzelelo lobushushu.
Ukusuka ekuKhethweni kwezinto ukuya ekuLungeleleni uQhagamshelo lweZibonelelo
Ukusombulula "udonga lokusebenza" lwentsimbi engagqwaliyo kufuna okungaphezulu kwesixhobo esinye esikumgangatho ophezulu; kufuna inkqubo yokuvelisa eqinisekisa ukuba yonke ibhetshi ihlangabezana nemigangatho efanayo eqinileyo. Kubasasazi behlabathi, umceli mngeni kukufumana iqabane elinokudibanisa obu buchule bobuchwephesha kunye nobonelelo oluzinzileyo nolukhulu. Isebenza phantsi kwenkqubo yolawulo lomgangatho ye-ISO 9001 eqinisekisiweyo, iJiacheng Tools iqinisekisa ukuba yonke into etyunjiweyo ye-cobalt ihlolwa ngokungqongqo kwezinto eziluhlaza, unyango lobushushu be-vacuum, kunye nokusilwa ngokuchanekileyo.
Intsebenziswano ethembekileyo ivumela abasasazi ukuba bagxile ekwandiseni imakethi kunokusombulula iingxaki zomgangatho.iinkonzo ezipheleleyo ze-OEM kunye neelebheli zabucala, okuvumela abanini beempawu ukuba banikezele ngobukhulu obulungiselelwe wena kunye neengubo ezikumgangatho ophezulu ezifana ne-Amber okanye i-TiN (Titanium Nitride) kwiimarike zabo zasekuhlaleni. Ezi ngubo zongeza ngakumbi ukutyeba kunye nokumelana nokuguguleka kwesiseko se-cobalt, zibonelela ngomaleko owongezelelweyo wokhuseleko kwindalo yokurhawuzelela yentsimbi engagqwaliyo. Ngamava eminyaka eli-15 yokuthumela ngaphandle, umzi-mveliso ugcina unxibelelwano olucacileyo kunye neeshedyuli zemveliso ezithembekileyo, ukuqinisekisa ukuba amaqabane aphesheya afumana rhoqo izixhobo ezifunekayo kubunjineli bokuchaneka kwanamhlanje.
Intsebenziswano eCwangcisiweyo yoMatshini oNgxamisekileyo
Ngaba i-cobalt iyimfuneko kwintsimbi engagqwaliyo? Nakweyiphi na indlela apho ukusebenza kakuhle, ukuchaneka, kunye nobude bexesha lesixhobo zizinto eziphambili, impendulo ngu-ewe oqinisekileyo. Nangona ii-HSS bits eziqhelekileyo zinokulawula imingxunya embalwa kwiishiti ezincinci, azinakukhuphisana nokuzinza kobushushu kunye nokugcinwa komphetho wee-alloys ezityebisiweyo ze-cobalt kwindawo yemizi-mveliso. Ukukhetha i-cobalt grade efanelekileyo kunye noqwalaselo lwejometri yeyona ndlela isebenzayo yokoyisa imingeni yoomatshini yee-alloys ezinzima.
I-Jiacheng Tools isazinikele ekuphuculeni ukusebenza kwe-HSS M35 kunye ne-M42 tooling. Ngokudibanisa isayensi ye-metallurgical kunye nemveliso echanekileyo, inkampani inika umqolo wobugcisa kwiingcali zokusebenza ngesinyithi kwihlabathi liphela. Kubasasazi kunye namagosa okuthenga kwimizi-mveliso, ukukhetha iqabane eliqondayo ezi zinto zihambelanayo linyathelo lokuqala lokufikelela ekugqweseni kokusebenza. Njengoko imfuno yehlabathi yezinto zentsimbi engagqwaliyo iqhubeka isanda, indima ye-cobalt drills esebenza kakhulu iya kuba yinto ebaluleke ngakumbi.
