Ukukhetha i-trill ye-twill elungileyo yeprojekthi yakho kubandakanya ukuqonda kwezinto ezintathu eziphambili: Izixhobo, ukudibanisa, kunye neempawu zejometri. Inye yezi zinto idlala indima ebalulekileyo kwintsebenzo kunye nokuqina kwe-drill bit. Nantsi indlela ukujonga ngendlela yokwenza isigqibo esiziyo.
Isixhobo
I-1. Intsimbi ye-high yentsimbi (HSS):
Intsimbi enesitepi esiphezulu (i-HSS) iphazamisekile kwizixhobo ezisika ngaphezulu kwenkulungwane, ixabisekile ngenxa yesicelo sayo esibanzi kunye nokufikeleleka. I-HSS inxile i-bits yaziwa ngokuguquguqukayo, iqhuba kakuhle i-drills yesandla kunye namaqonga azinzileyo anjengoomatshini bokuziphatha. Inzuzo ephambili ye-HSS inamandla ayo ebukhali, yandisa ububele be-onger ye-Drill Bits kwaye yenze ukhetho olunempumelelo kwizixhobo ze-lathe. Ngaphaya koko, i-HSS inamabanga ahlukeneyo, nganye ineengoma ezahlukeneyo zokugcina iimfuno ezithile zokusika. Ezi ntlobo ngamanqanaba ensimbi yongeza kwi-quiptis, eyenza ukuba ibe yinto ebalulekileyo kwimisebenzi yomatshini eyahlukeneyo.
I-2. I-Cobabalt HSS (i-hss okanye i-hssco):
Xa kuthelekiswa ne-HSS yendabuko, i-Cobabalt Hss ibonisa ubukhali obukhulu kunye nonyamezelo lobushushu. Olu ncedo kwipropathi lukhokelela ekuchasweni kwe-arasion, ukwenza i-hsed drill bill ihlale ixesha elide kwaye isebenza ngokufanelekileyo. Ukufakwa kweCobalt kwi-HSSE AKUKHO BUNGOZI KAKHULU NGOKUKHUSELEKILE KAKHULU KUNYE NOKUKHUSELEKO IXESHA LOKUGQIBELA. Kanye njenge-HSS eqhelekileyo, i-HISSE Bits igcina izibonelelo zokungazibukiswa kwakhona, ezinokufikelela ebomini babo obunokuzonwabisa. Ubukho be-Cobabat kwi-HISE b.S.S. SETYAMAKenza ukuba ezi bits zilungele imisebenzi yokugrumba ethe kratya apho kuqhekezwayo kunye nokuchasana no-Abrase kubalulekile.
I-3. I-carbide:
I-carbide sisimo sentsimbi ye-matrix, ngokuyintloko senziwe nge-carbide ye-tungsten enezibonda ezahlukeneyo. Iphengulula i-HSS embindini, unyamezelo, kunye nokuchaswa kuka-Alasion. Ngelixa iindleko ezixabisa kakhulu, izixhobo ze-carbide zigqwesisela kwi-Lindepan kunye nesantya somatshini. Bafuna izixhobo ezikhethekileyo zokulolonga kwakhona.
Ukuthuthumela
I-Drill Cutress i-bit ihluka ngokubanzi kwaye ikhethwe ngokusekwe kwisicelo. Nalu umbono olufutshane lwengubo ethile eqhelekileyo:
I-1. I-Insweli (iqaqambile):
Ngowona mbala uqhelekileyo kwi-HSS i-bits. Ilungele izixhobo ezithambileyo ezinje ngo-Alminium Alloys kunye ne-carbon yekhabhoni, izixhobo ezingafakwanga zezona zifikelelekayo.
I-2. I-Oneaside emnyama
Ibonelela ngolungelelwano olungcono kunye nokuxhathisa ubushushu kunezixhobo ezingafakwanga, ukuphucula i-Lifepan ngaphezulu kwe-50%.
I-3. Titanium Nitride (Tin)
I-tits ye-tittiium-enamagqabi aqhuba kakuhle kwizinto ezininzi zesicelo ngenxa yeempawu zabo zentsebenzo. Okokuqala, iphucula ubunzima kunye nokunganyangeki kwe-alasion ngokudibana, ukuvumela ukuba incinci ukuba ihlale ibukhali ngelixa iqhuba ngezinto ezinzima, kwaye ibonelela ubomi obude benkonzo. Ezi bits zinciphisa ukungqubana kunye nokwakha ubushushu, ukwanda kokusika ukusebenza ngempumelelo ngelixa sikhusela kancinci. I-bits efakwe i-Titanium ifanelekile ukuba isetyenziswe kwizinto ezininzi, ezinje ngentsimbi engenasibala, ialuminium kunye neenkuni, zisenza ukuba zilungele ubunjineli kunye nezicelo zekhaya. Ukongeza, ezi biti zingena kwizixhobo ngokukhawuleza kwaye zicocekile, zibonelela ngomphezulu omncinci wokusika. Ngelixa i-titanium-ephantsi inokuthi ihlawule ngaphezulu kweedrives ezingaphezulu, ubuchule bazo obuphakamileyo kunye nobomi obude bubenze babuyele kutyalo-mali lwezicelo ezifuna ukumelana okuphezulu kwe-arasion kunye nokusika ngokuthe ngqo.
I-4. I-Alweminium Titanium Nitride (Altin)
Okokuqala, iingubo zangaphantsi zinobushushu obukhulu, zibasebenzela ukuba bagqwesise ekunciphiseni ngesantya esiphezulu kunye nomatshini obunamaqondo aphezulu. Okwesibini, oku kuhlekisana kakhulu ukuphucula imeko yokunganyangeki kwe-abrashion kunye nokudlulisela isixhobo sobomi, ngakumbi xa kufakwa izinto ezinzima zentsimbi, i-titanium ye-alloys kunye ne-Alkeys. Ukongeza, i-Altin iqengqeleka inciphisa ukungqubana phakathi kwe-Drill bit kunye nomsebenzi, ukuphucula ukusebenza kakuhle kunye nokunceda ekufezekiseni indawo yokusika. Ikwanokumelana nokunganyangeki okufanelekileyo kunye nokuzinza kwemichiza, ukuyenza ukuze kugcinwe intsebenzo kwiindawo zokusebenza ezinzima. Kuzo zonke iindawo, ezinama-Altin-Altin zilungele isantya esiphezulu, iinkqubo zomatshini ezikumgangatho ophezulu, kwaye zilungele ukuphatha izixhobo ezinzima ezibangela ucelomngeni lokuqhuba okungekho siqhelekileyo.
Iimpawu zejometri
1. Ubude:
Umlinganiso wobude obunefuthe kubuncinci. Ukukhetha i-drill bill kunye nobude obuneflethi olwaneleyo kwi-chip yokukhuphela kunye nobuncinci obuncinci unokuphucula i-rigidity kunye nesixhobo sobomi. Ubude obungonwabanga bungonakalisa kancinci. Kukho imigangatho yobude eyahlukeneyo ukukhetha kwimarike. Ubude obuxhaphakileyo buqhekezile, i-stubby, nt 340, dana 338, njl.
I-2. I-Drill Angle:
I-118 ° Angle iqhelekileyo ixhaphakile kwiintsimbi ezithambileyo njenge-carbon yentsimbi kunye ne-aluminium. Ngokwesiqhelo ingenamandla ozibonelelayo, ifuna umngxunya wenqwelomoya. I-135 ° Ingqungquthela ye-135, kunye nenqaku lakhe lokuzila, lisusa isidingo semingxunya eyahlukileyo ebonakalayo, esonga ixesha elibonakalayo.
Ukuqukumbela, ukukhetha i-twill ye-twill ye-twill efanelekileyo kubandakanya ukulinganisa iimfuno zezinto ezenziweyo, i-LindePan enqwenelekayo, kunye nokusebenza kwe-bit, kunye neemfuno ezithile zeprojekthi yakho. Ukuqonda ezi zinto kuya kuqinisekisa ukuba ukhetha eyona isebenzayo nenempumelelo ye-right kwiimfuno zakho.
