Uthotho: Kutheni ii-Drill Bits zingaphumeleli | Inqaku le-10
Amagama angundoqo: i-engile ye-drill bit point, i-118 vs 135 drill bit, i-split point drill bit, i-HSS drill bit, isikhokelo sokukhetha i-drill bit
Ukuba uhlela imibuzo eyaneleyo ye-drill bit, uyayibona ipateni. Abathengi babuza ukuba yeyiphi i-engile yenqaku "engcono" - 118° okanye 135° - ngokungathi enye ingcono kunenye. Akunjalo. I-engile nganye isombulula ingxaki eyahlukileyo, kwaye ukudideka kudla ngokuvela kwikopi yokuthengisa ephatha i-135° split point njengento ethatha indawo yendawo yonke endaweni yesixhobo esithile somsebenzi othile.
Sizenzela zombini, ngobuninzi, abathengi abazisebenzisa ngeendlela ezahlukeneyo kakhulu. Nantsi into egqibayo ukuba zeziphi eziza kusetyenziswa kumthengi — kwaye kutheni.
Yintoni etshintsha i-Angle yePoint ngokwenene
I-engile yenqaku yi-engile eyenziwe phakathi kwemilebe emibini yokusika kwincam yokubhola. Idla ngokuchazwa ngokuthi "i-118° ibukhali, i-135° ithambile," into echanekileyo kodwa engaphelelanga. Oko kulawulwa yiloo engile zizinto ezintathu:
• Kufuneka i-axial thrust engakanani ukuze kuqalwe ukusika.Ingongoma ebukhali igxininisa amandla kwindawo encinci, ukuze ilume ngaphandle kokutyhala kakhulu. Ingongoma ethe tyaba isasaza loo mthwalo kumda omde wokusika.
• Indlela eziphatha ngayo umphetho wetshiseli.Umphetho wetshiseli — icandelo elifutshane elisembindini wencam, apho kudibana khona iifluti ezimbini — alinqumli. Lityhalela ecaleni izinto. Lo ngumthombo omkhulu wokungqubana nobushushu ekuqaleni komngxuma, kwaye liziphatha ngokwahlukileyo kuxhomekeke kwikona yenqaku.
• Ukwakheka kwetships.Kwi-118°, ubukhulu be-chip buyahluka ngakumbi kumphetho wokusika — bukhulu kwikona engaphandle, bunciphile kufutshane nombindi. Kwi-135°, ubukhulu be-chip buyalingana ngakumbi, nto leyo ebalulekileyo kwizinto ezivelisa ii-chips ezinde, eziqinileyo.
Akukho nanye kwezi zinto ezibonakalisa uluvo. Yiyo loo nto kukho la ma-engile mabini kwasekuqaleni, kwaye yiyo loo nto enye ingeyona nje "inguqulelo engcono" kwenye.
Kutheni i-135° Phantse Ihlala Iza Nenqaku Eliqhekekileyo
Oku kufanelekile ukucaciswa kakuhle, kuba yeyona ndawo uninzi lwezikhokelo zokufumana ulwazi eziphosakele kuyo okanye ezingayifumani ngokupheleleyo.
Umphetho we-chisel awunqumli — ukhupha izinto. I-engile eyenza ngayo oku (i-engile yayo esebenzayo ye-rake) iba mbi ngakumbi njengoko i-engile ye-point iba tyaba. Ngokwendlela esebenzayo: xa i-point ithambile, kokukhona i-center part ikhula ngakumbi endaweni yokucheba. I-point ye-135°, xa ingachukunyiswanga, inengxaki ye-chisel-edge embi kune-point ye-118° — ayincinci.
Oko kuchasene noko uninzi lwabathengi lukucingayo. Ingqiqo ithi: "I-135° ithambile, i-flatter kufuneka ithethe ukuba ithambile, i-soft kufuneka ithethe ukuba kulula ukuqala." Enyanisweni, i-135° engahlulwanga ihamba ngaphezulu kwe-118° eqhelekileyo, kuba i-geometry ekufuneka iyenze izinze kwimiphetho engaphandle yenza embindini ube mbi.
I-split point geometry ikhona ngokukodwa ukulungisa oku. Igaya imiphetho emibini eyongezelelweyo yokusika kwi-chisel edge, iguqula elo candelo liphakathi elingasikwanga libe ngumphezulu wokusika wokwenyani. Yiloo nto inika i-135° split point yayo yokuziphatha kwayo okuzijongayo kunye nokutyhala kwayo okusezantsi kokuqala - hayi i-engile ye-point ngokwayo.
Kungoko ke ezi zinto zimbini zithengiswa rhoqo. I-135° point ngaphandle kwe-split point geometry ayisebenzi kakuhle kwizicelo ezi-135° ezikhethiweyo — imingxunya echanekileyo kwizinto eziqinileyo, umsebenzi we-CNC ngaphandle kwe-center punch, ukugqobhoza kwiindawo ezigobileyo okanye ezityibilikayo. Akukho nto ishiyekileyo xa utsiba inyathelo le-split point, ngoko ke bambalwa abavelisi abakhathazekayo ngokunikezela ngaloo ndibaniselwano. Asingomthetho onzima we-geometry. Kukuba i-135° ngaphandle kwe-split point iyoyisa injongo yayo.
Ingcamango ephosakeleyo eqhelekileyo ekufanele ilungiswe ngokuthe ngqo: i-split point ayixhomekekanga kwi-135° kuphela.I-118° split point ikhona kwaye isetyenziswa — ikakhulu apho umthengi efuna i-low thrust kunye ne-general-purpose versatile ye-118°, kodwa ikwafuna i-centering engcono kune-standard point ye-118°, ngaphandle kokuya kwi-flat, i-weave-resistant geometry ye-135°. Ayixhaphakanga kuba uninzi lwezicelo ze-118° azifuni loo nqanaba lokuchaneka kwe-centering kwasekuqaleni, kodwa luyilo lokwenyani, olunokwenziwa — aluyonto inomdla kakhulu.
I-Angle yeNgcali Ayilo Ibali Elipheleleyo — Ukuziphatha kwezinto eziphathekayo kuyahluka
Ukuphatha i-point angle njenge-single variable echaza impumelelo yokubhola kwenza ingxaki ibe lula kakhulu. Imizekelo embalwa apho umthetho othi "izinto eziqinileyo, i-flatter angle" uyawa:
•I-aluminiyam:I-engile yenqaku ayibalulekanga kangako apha kune-engile ye-helix kunye nokukhululeka kwemilebe. I-drill ene-engile ye-helix ephezulu (34°–38°) kunye nokukhululeka kwemilebe okukhulu isusa iitships ngokukhawuleza ngokwaneleyo ukuthintela umda owakhelweyo — imo yokwenyani yokusilela kwi-aluminiyam — nokuba inqaku liyi-118° okanye i-135°.
•Jula i-ayini:Ivelisa iitships ezimfutshane, ezijijekileyo kunezinde, ngoko ke inzuzo yokukhupha iitships ze-135° ayibalulekanga kangako apha kunezixhobo ezivelisa iitships eziqhubekayo. Iivenkile ezininzi zisebenzisa i-118° kwisinyithi esityhidiweyo ngaphandle kwengxaki.
•Yenziwe ngentsimbi eshayinayo:Kulapho i-135° split point ifumana khona udumo lwayo. Ukusebenza okungaqinanga kuyaqina xa kukho ukungqubana, kwaye isenzo sokulima se-chisel edge ekuqaleni komngxuma yisona kanye esibangela ukuqina kwaloo mngxuma. Ukunciphisa loo mngxuma nge-split point geometry akunyanzelekanga ukuba ufuna umgangatho ohambelanayo wemingxuma kuyo yonke imveliso.
•Iiplastiki kunye nezinto ezidityanisiweyo:Ingqiqo iyajika ngokupheleleyo. Ezi zinto zifuna i-blunter, hayi i-curvy, ukuze kuthintelwe ukuqhekeka okanye ukuqhekeka njengoko i-drill iphuma kwi-material. Isikhokelo se-angle ye-metal-drill point point asisebenzi.
Le pateni ihambelana noko sikubonileyo kuyo yonke imo yokusilela kolu ngcelele: inombolo yephepha le-spec ayifane ichaze lonke ibali. I-point angle idibana ne-helix angle, i-lip relief, kunye nobukhulu bewebhu. Ukuthatha oku njengesigqibo esizimeleyo yindlela abathengi abagqibela ngayo bene-drill bit echanekileyo ephepheni nengalunganga emsebenzini.
Oku kuthetha ukuthini xa kufunwa i-Sourcing
Ukuba uchaza iibhithi zokubhola zevenkile yezinto ezixutyiweyo, i-118° yenjongo eqhelekileyo igubungela uninzi lomsebenzi wesiqhelo ngexabiso eliphantsi. Ukuba imveliso yakho ihambelana nentsimbi engatyiwayo, intsimbi exutyiweyo, okanye izinto eziqinileyo — okanye ukuba inkqubo yakho ayivumeli inyathelo lokubethela eliphakathi — i-135° yokuqhekeka ayilokhetho, yimfuneko yokugcina ukunyamezelana kunye namaxesha omjikelo engaguqukiyo.
I-engile egximfizwe kwi-spec sheet iluncedo kuphela xa sele uyazi ukuba yintoni ingxaki eyisombululayo. I-drill bit ehamba, etyibilikayo, okanye egugayo kwangethuba ayisiyonto imbi yoku-drill bit — isenokuba yi-point angle engalunganga kwinto ebiceliwe ukuba iyenze.
Malunga nolu ngcelele
Kutheni i-Drill Bits Ingaphumeleli luluhlu lobuchwephesha olubhalwe liqela lethu lemveliso. Inqaku ngalinye ligxile kwinto enye ethile ekusebenzeni kwe-drill bit - ukusuka kwizinto eziluhlaza ukuya ekupakisheni. Injongo ilula: ukunceda abathengi baqonde ukuba bathenga ntoni, kunye nemibuzo abanokuyibuza.
