Ukukhetha i-twist drill bit yeprojekthi yakho kubandakanya ukuqonda izinto ezintathu eziphambili: imathiriyeli, ukugquma, kunye neempawu zejometri. Nganye kwezi zinto zidlala indima ebalulekileyo ekusebenzeni kunye nokuqina kwe-drill bit. Nalu ujongo olusondeleyo kwindlela yokwenza isigqibo esinolwazi.
Izinto eziphathekayo
1. Isinyithi esinesantya esiphezulu (HSS):
I-Speed-Speed Steel (i-HSS) sele iyinxalenye yezixhobo zokusika isithuba esingaphezu kwenkulungwane, ixabiswa ngenxa yokusetyenziswa kwayo okubanzi kunye nokufikeleleka kwayo. I-HSS drill bits ziyaziwa ngokuguquguquka kwazo, ziqhuba kakuhle ngezandla zombini kunye namaqonga azinzileyo afana noomatshini bokushicilela. Inzuzo engundoqo ye-HSS kukukwazi ukulola kwakhona, ukwandisa ubomi obude be-drill bits kwaye iyenze ibe lukhetho olungabizi kakhulu kwizixhobo ze-lathe. Ngaphaya koko, i-HSS inamabanga ahlukeneyo, ngalinye lineengoma ezahlukeneyo zokuhlangabezana neemfuno zokusika. Olu didi kumanqanaba entsimbi yongeza ukuguquguquka kwe-HSS, iyenza ibe yinto eguquguqukayo kwaye iyimfuneko kwimisebenzi eyahlukeneyo yomatshini.
2. I-Cobalt HSS (i-HSSE okanye i-HSSCO):
Xa kuthelekiswa ne-HSS yendabuko, i-Cobalt HSS ibonisa ubunzima obuphezulu kunye nokunyamezela ubushushu. Oku kongezwa kwiipropathi kukhokelela ekuphuculeni ngokubonakalayo ukuxhathisa kwe-abrasion, okwenza i-HSSE drill bits yomelele kwaye isebenze. Ukudityaniswa kwe-cobalt kwi-HSSE akupheleli nje ekubeni negalelo ekwandeni kokuchasa kwe-abrasion kodwa kwandisa ubomi bayo bonke. Ngokufana ne-HSS eqhelekileyo, ii-bits ze-HSSE zigcina i-benefit yokuphinda ilolwe, nto leyo eyandisa ngakumbi ubomi babo obusebenzisekayo. Ubukho be-cobalt kwi-HSSE kwenza ezi bits zifaneleke ngakumbi kwimisebenzi yokomba enzima kakhulu apho ukuqina kunye nokuchasana ne-abrase kubalulekile.
3. Carbide:
I-Carbide yintsimbi ye-matrix composite, eyenziwe ngokuyinhloko nge-tungsten carbide enezibophelelo ezahlukeneyo. Iyodlula kakhulu i-HSS ngobulukhuni, ukunyamezela ubushushu, kunye nokuxhathisa i-abrasion. Ngelixa zibiza kakhulu, izixhobo ze-carbide zigqwesa kubomi kunye nesantya somatshini. Bafuna izixhobo ezikhethekileyo zokulola kwakhona.
Ukwaleka
Iingubo ze-Drill bit ziyahluka ngokubanzi kwaye zikhethwa ngokusekelwe kwisicelo. Nantsi inkcazo emfutshane yezinye iingubo eziqhelekileyo:
1. Ingagqunywanga (Eqaqambileyo):
Ngowona mbala uqhelekileyo we HSS drill bits. Efanelekileyo kwizinto ezithambileyo ezifana ne-aluminium alloys kunye ne-carbon steel ephantsi, izixhobo ezingafakwanga zezona zifikelelekayo.
2. IMaleko ye-Oxide emnyama:
Ibonelela ngokuthambisa okungcono kunye nokumelana nobushushu kunezixhobo ezingagqunywanga, iphucula ubomi obungaphezulu kwama-50%.
3. IMaleko ye-Titanium Nitride (TiN):
Amasuntswana e-Titanium-coated drill asebenza kakuhle kwiimeko ezininzi zokusetyenziswa ngenxa yeempawu zabo zokusebenza ezizodwa. Okokuqala, Yongeza ubulukhuni kunye nokuxhathisa kwe-abrasion ngokusebenzisa i-coating, ivumela i-bit ukuba ihlale ibukhali ngelixa ubhobhoza ngokusebenzisa izinto ezinzima, kunye nokubonelela ubomi benkonzo obude. Ezi bits zinciphisa ukukhuhla kunye nokwakhiwa kobushushu, ukwandisa ukusebenza kakuhle kokusika ngelixa ukhusela i-bit ekutshiseni. I-Titanium-plated bits ifanelekile ukusetyenziswa kwizinto ezininzi, ezifana nensimbi engenasici, i-aluminium kunye nemithi, ezenza zibe zilungele ubunjineli kunye nezicelo zendlu. Ukongeza, ezi bits zingena kwizinto ezikhawulezayo kwaye zicocekile, zinika indawo yokusika ecocekileyo. Ngelixa i-titanium-plated drills inokubiza ngaphezulu kwe-drills eqhelekileyo, ukusebenza kwabo okuphezulu kunye nobomi obude bubenza babe yimbuyekezo efanelekileyo kutyalo-mali lwezicelo ezifuna ukuxhathisa okuphezulu kwe-abrasion kunye nokusika ngokuchanekileyo.
4. IAluminiyam ye-Titanium Nitride (AlTiN) yoMgqumo:
Okokuqala, iingubo ze-AlTiN zikwazi ukumelana nobushushu, zibenza baphumelele ekusikeni ngesantya esiphezulu kunye nomatshini we-alloys ephezulu yobushushu. Okwesibini, le ngubo iphucula kakhulu ukuxhathisa kwe-abrasion kwaye yandisa ubomi besixhobo, ngakumbi xa kusetyenzwa izinto ezinzima ezifana nentsimbi engatyiwa, iialloyi zetitanium kunye ne-nickel-based alloys. Ukongeza, ukugquma kwe-AlTiN kunciphisa ukungqubana phakathi kwe-drill bit kunye ne-workpiece, ukuphucula ukusebenza kakuhle komatshini kunye nokunceda ukufezekisa indawo yokusika elula. Kwakhona inokumelana ne-oxidation efanelekileyo kunye nokuzinza kweekhemikhali, okuyenza ikwazi ukugcina ukusebenza kwiindawo zokusebenza ezinzima. Kuzo zonke, i-AlTiN-coated drills ifanelekile kwi-high-speed, i-high-precision-precision machining applications, kwaye ifaneleke ngokukodwa ukuphatha izinto ezinzima ezibeka umngeni kwiidrill eziqhelekileyo.
Iimpawu zeJometri
1. Ubude:
Umlinganiselo wobude ukuya kwidayamitha uchaphazela ubungqongqo. Ukukhetha i-drill bit enobude obaneleyo befluti yokukhutshwa kwetshiphu kunye nokuxhonywa okuncinci kunokomeleza ubulukhuni kunye nobomi besixhobo. Ubude befluti obungonelanga bunokonakalisa intwana. Kukho imigangatho eyahlukeneyo yobude bokukhetha kwiimarike. Obunye ubude obuqhelekileyo yiJobber, stubby, DIN 340, DIN 338, njl.
2. I-Engile yeNqaku loMzobo:
I-angle ye-118 ° iyinto eqhelekileyo kwiintsimbi ezithambileyo njengentsimbi ephantsi yekhabhoni kunye ne-aluminium. Idla ngokungakwazi ukuzimela, ifuna umngxuma wokulingwa. I-angle ye-135 ° ye-angle, kunye ne-self-centing feature yayo, isusa isidingo somngxuma wokumisa owahlukileyo, ukugcina ixesha elibalulekileyo.
Ukuqukumbela, ukukhetha i-twist drill bit echanekileyo ibandakanya ukulungelelanisa iimfuno zemathiriyeli egrunjwayo, ubomi obunqwenelekayo kunye nokusebenza kwebit, kunye neemfuno ezithile zeprojekthi yakho. Ukuqonda le miba kuya kuqinisekisa ukuba ukhetha eyona nto isebenzayo nesebenzayo yokugrumba kwiimfuno zakho.
