Ukubhola yinxalenye ebalulekileyo ye PCB Itekhnoloji yokulungisa intaba, kunye nokukhethwa kwesixhobo sokugrumba kubaluleke kakhulu. Isuntswana le-carbide e-welding, eyaziwa ngamandla alo oxhulumaniso oluphezulu phakathi kwe-drill tip kunye nomzimba wokusika, inokuqhubekeka imingxunya enoburhabaxa bomhlaba, ukunyamezelana kokungavuleki okuncinci kunye nokuchaneka kwendawo ephezulu. Xa isikisi sokutshixa siqinisiwe, i-drill yesithsaba inokufikelela kwindawo ephezulu njengokutya kwe-welding.

Abantu abaninzi ngempazamo bakholelwa kwelokuba ukubhola kufanele ukwenziwa ngeqondo lokutya okuphantsi kunye nesantya esisezantsi. Oku bekusoloko kuyinyani, kodwa ii-carbide bits zanamhlanje zilibali elahlukileyo. Ngapha koko, ukukhetha ibhithi elungileyo kunokwandisa imveliso kunye nokunciphisa iindleko kumngxunya kwibhodi nganye.

Zine iindidi ezisisiseko zokumba izixhobo ezinemiphetho yokusika i-carbide efumanekayo kumsebenzisi wokugqibela: i-carbide eqinileyo, ukufakwa kwe-indexable, iingcebiso ze-carbide drill, kunye neengcebiso ze-carbide drill. Nganye inezibonelelo zayo kwisicelo esithile.

Iibhithi zekhabhide yokuqala eqinileyo zisetyenziswa kumaziko ophando lwangoku. Yenziwe nge-carbide ecolekileyo kwaye yambathiswe nge-TIAlN yobomi besixhobo, ezi zinto zizenzela zona zibonelela ngolawulo lwe-chip kunye nokususa kuninzi lwezixhobo zomsebenzi ngenxa yemiphetho yazo eyilwe ngokukodwa. Ijiyometri yokuzimela kunye nokuchaneka kweebhite ze-carbide bits kuqinisekisa ukuba imingxunya ekumgangatho ophezulu iyafezekiswa ngaphandle kokuphinda kusebenze ngomatshini.

Iimpawu zebhanti ezinesalathiso zigubungela uluhlu olubanzi lweedayimitha kubunzulu obuvela kwi-2XD ukuya kwi-5XD. Zingasetyenziswa kuzo zombini izicelo ezijikelezayo kunye neentsimbi. Ezi zinto zisebenzisa i-Angle ye-geometric Angle yezixhobo ezininzi zomsebenzi ukunciphisa amandla okusika kunye nokubonelela ngolawulo lwe-chip olulungileyo.

Isinyithi sokugrumba esine-welding senza imingxunya ngokugqitywa komphezulu ophakamileyo, ngokuchaneka okuphezulu kunye nokuchaneka kwendawo elungileyo ngaphandle kokugqiba. Ngokupholisa ngemingxunya, iingcebiso ezincinci ezinokusetyenziswa zingasetyenziselwa kumaziko okuchwetheza, i-CNC lathes, okanye ezinye izixhobo zomatshini ezinokuzinza ngokwaneleyo kunye nesantya sokujikeleza.

Ifom yokugqibela idibanisa umzimba osikiweyo wentsimbi kunye nenqaku elisusiweyo elibizwa ngokuba sisithsaba. Uqheliso lubonelela ngokuchanekileyo ngokufanayo nge-welded bit ngelixa kufikelelwa kwimveliso ephezulu ngexabiso eliphantsi loomatshini. Esi sizukulwana silandelayo sinesithsaba se-carbide sibonelela ngokunyusa okuthe ngqo kunye ne-angle geometric ye-geometric eqinisekisa ngokuchaneka okuphezulu.

Qaphela ngononophelo ukunyamezeleka kunye nozinzo lwesixhobo somatshini

Umzi mveliso kufuneka ukhethe isuntswana ngokungqinelana nokunyamezelana okuthe ngqo kumatshini. Imingxunya emincinci enobubanzi idla ngokuba nokunyamezelana okuqinileyo. Ke ngoko, abavelisi bezinto ezincinci bahlela iibits ngokuchaza ukuvulwa okungacacanga kunye nokunyamezelana okuphezulu. Kuzo zonke iifom zokugrumba, i-carbide bit eqinileyo inonyamezelo oluqinileyo. Oku kubenza babe lolona khetho lufanelekileyo lokugrumba imingxunya ngokunyamezelana okuqinileyo. Umzi mveliso unokugrumba nge-10mm ubukhulu be-carbide bit ngokunyamezelana ukusuka ku-0 kuye + 0.03mm.

Kwelinye icala, amasuntswana atyhidiweyo okanye amasuntswana aphezulu anesithsaba se-carbide anokubuyiselwa kunyamezelo ukusuka ku-0 kuye + 0.07mm. Ezi zibonda zihlala zikhethwa kakuhle kwiinkqubo zemveliso yokomba.Isalathiso sentsimbi enesalathiso ngumsebenzi osindayo kolu shishino. Ngelixa ixabiso labo eliphambili lihlala liphantsi kunezinye iibits, zikwanokunyamezelana okukhulu, ukusukela ku-0 ukuya ku-0.3mm ngokuxhomekeke kubungakanani be-diameter-to-hole-ratio. Oku kuthetha ukuba umsebenzisi wokugqibela unokusebenzisa isaliti esine-indexable xa unyamezelo lomngxunya luphezulu, kungenjalo kufuneka bakulungele ukuwugqiba umngxunya ngokusika okudikayo. Kunye nokunyamezelana kwemingxunya, umzi-mveliso kufuneka uqwalasele uzinzo lwesixhobo somatshini kwinkqubo yokhetho. Kungenxa yokuba uzinzo lokuqinisekisa ubomi besixhobo kunye nokuchaneka ngokuchanekileyo. Umzi-mveliso uya kuqinisekisa ngobume boomatshini bokuluka, izixhobo kunye nezixhobo. Kuya kufuneka bakuthathele ingqalelo ukuzinza kwendalo. Umzekelo, i-carbide bits monolithic ibonelela ngqongqo olufanelekileyo, oluvumela ukuchaneka okuphezulu.

Kwelinye icala, ii-blade blade bits ezinokuchaphazeleka zithambekele ekuphambukeni. Ezi zixhobo zixhotyiswe ngamacangci amabini – iblade yangaphakathi embindini kunye nebala elolulela ngaphandle ukusuka kwibala elingaphakathi ukuya emaphethelweni- kwaye ekuqaleni ibloko enye kuphela ethatha inxaxheba ekusikeni. Oku kudala imeko engazinzanga ebangela ukuba umzimba omncinci uphambuke. Kwaye kukhulu ukuphambuka kwenyanga. Ke ngoko, xa usebenzisa i-4XD kunye nezinye iibheyidi ezinesalathiso, isityalo kufuneka siqwalasele ukunciphisa isondlo semilimitha yokuqala size sandise ukutya kuqheleke. Isuntswana esinesinyithi kunye nesithsaba esiguqulwayo siyilelwe njengemiphetho yokusika macala emibini eyenza i-Angle yejiyometri eyi-self-centering. Uyilo lokusika oluzinzileyo luvumela isuntsu ukuba lingene kwindawo yokusebenza ngesantya esipheleleyo. Ukwahluka kuphela kuxa isuntswana lingaxhomekekanga kumphezulu womatshini. Kuyacetyiswa ukunciphisa ukutya nge-30% ukuya kuma-50% ngexesha lokusikwa nokusikwa.

Umzimba omncinci wesinyithi uvumela ukuphambuka kancinci, ukuwenza ukuba usetyenziswe ngempumelelo kwi-lathes. I-carbide bit eqinileyo enokuqina okuqinileyo inokuqhekeka ngokulula, ngakumbi xa umsebenzi ungagxili kakuhle. Sukutyeshela iichips kwimizi-mveliso emininzi enengxaki yokususwa kwe-chip. Ngapha koko, ukususwa okungafunekiyo kwe-chip yeyona ngxaki ixhaphakileyo ekubholeni, ngakumbi xa kusenziwa intsimbi ethambileyo. Kwaye akunamsebenzi ukuba yeyiphi into oyisebenzisayo. Iifektri zihlala zisebenzisa ukupholisa kwangaphandle ukusombulula le ngxaki, kodwa kuphela kubunzulu bemingxunya engaphantsi kwe-1XD kunye nokunciphisa iiparameter zokusika. Ngaphandle koko, kufuneka basebenzise isipholisi esifanelekileyo ukutshatisa ukuhamba kunye noxinzelelo lomngxuma. Kwizixhobo zomatshini ezingenasipholisi sendawo yokuluka, umzi-mveliso kufuneka usebenzise isipholisi ukuya kwisixhobo. Khumbula, okukhona usiba nzulu umngxunya, kokukhona kunzima ngakumbi ukususa iichips kunye noxinzelelo olupholileyo ngakumbi luyafuneka. Soloko ujonga inqanaba lokuhamba lokupholisa eliphantsi lomenzi. Kumaqondo okuhamba asezantsi, ukutya okuncitshisiweyo kunokuba yimfuneko. Ukuphonononga umjikelo wobomi beendleko zemveliso okanye iindleko kumngxunya ngamnye yenye yeendlela eziphambili ezichaphazela ukubhola namhlanje. Oku kuthetha ukuba abavelisi bezinto kufuneka bafumane iindlela zokudibanisa iinkqubo ezithile kunye nokuphuhlisa iibits ezinokufumana amaqondo aphezulu okutya kunye nokusebenza ngesantya esiphezulu.

Iibithi zamva nje ezineengcebiso eziqinileyo ezinokutshintsheka ze-carbide zibonelela ngoqoqosho oluphezulu. Endaweni yokutshintsha umzimba uphela, umsebenzisi wokugqibela uthenga kuphela intloko ye-carbide ebiza imali efanayo nokubuyisa i-carbide bit eqinileyo okanye eqinileyo. Ezi zithsaba zithathelwa indawo ngokulula kwaye zichanekile, zivumela umzi-mveliso ukuba usebenzise izithsaba ezininzi kumzimba omnye ukubhola ubukhulu bemingxunya eyahlukeneyo. Le nkqubo yemodyuli yokomba inciphisa iindleko zoluhlu lweebhitim ezinobubanzi ukusuka kwi-12mm ukuya kwi-20mm.

Ukongeza, ishenxisa iindleko zokuba nesipele esincinci xa isuntswana esine-welding okanye i-carbide bit ephindaphindayo. Umzi-mveliso kufuneka uthathe ingqalelo kubomi besixhobo xa uphonononga iindleko kumngxunya ngamnye. Ngokwesiqhelo, isuntswana le-carbide elinye linokuphinda lijikeleze amaxesha angama-7 ukuya kweli-10 kumzi-mveliso, ngelixa isinyithi esirhabaxa sinokuphinda sijikeleze amaxesha ama-3 ukuya kwayi-4. Ngakolunye uhlangothi, i-Crown drill bits, inomzimba wokusika isinyithi onokutshintsha ubuncinci ubuncinci i-20 ukuya kwi-30 isithsaba ngelixa usenza intsimbi.

Kukwakho nombuzo wemveliso. Iintsimbi ze-carbide zentsimbi okanye ezomeleleyo kufuneka ziphinde zirhangqwe; Ke ngoko, iifektri zihlala zinciphisa isantya ukuthintela iitshipsi ezinamathelayo. Nangona kunjalo, into ebuyiswayo ayifuni ukuphinda ijikeleze, ke umzi-mveliso unokuqhubekeka ngesondlo esaneleyo kunye nesantya ngaphandle kokukhathazeka malunga ne-cemented carbide chip.
