Uthotho: Kutheni ii-Drill Bits zingaphumeleli | Inqaku le-11
Amagama angundoqo: uyilo lweflute ye-drill bit, i-chip evacuation, i-drill bit helix angle, i-parabolic flute drill bit, ubukhulu bewebhu, ukupakisha iitship, ukubhola umngxuma onzulu i-HSS, iflute eqhelekileyo kunye neflute ye-parabolic

Inqaku lokugqibela kolu ngcelele lijonge indlela i-angle yenqaku ehambelana ngayo nezinto ezahlukeneyo - xa umphetho wokusika usika izinto kwindawo yokusebenza. Le iphinda iqale emva koko: xa itshiphu isikiwe, kusafuneka ishiye umngxuma. Ukuba ayikwenzi oko, yonke into enyukayo - umgangatho wezinto, unyango lobushushu, ijiyometri yenqaku - ayisayi kuba namsebenzi. Intwana inokwenziwa ukusuka kwi-M35 yokwenyani ize igutywe iye kwincwadi yesifundo ephuhliswe nge-135° kwaye isahluleke, ukuba iflute ayikwazi ukukhupha itshiphu ngokukhawuleza.

Apho iChip Iya Khona Ngokwenene

I-twist drill isusa izinto ezikwincam, kodwa isusa ezo zinto ecaleni kweflute - umjelo ojikelezayo ukusuka kumphetho wokusika ukuya kwi-shank. I-chip ayiphumi emngxunyeni yodwa; ikhwela kuloo mjelo, ityhalelwa kukujikeleza kwe-bit kunye nokuma kodonga lweflute. Izinto ezintathu ezitshintshayo zigqiba ukuba olo hambo luhamba kakuhle kangakanani: ukuba i-spiral inyuka kangakanani (i-helix angle), ukuba ingakanani i-solid metal ehleli embindini we-bit (ubukhulu bewebhu), kunye nokuba ingakanani indawo evulekileyo enikezelwa yiflute channel (uhlobo lweflute). Akukho nanye kwezi enokulungiswa yodwa - itshintshisana, kwaye ibhalansi elungileyo ixhomekeke kwizinto kunye nobunzulu bomngxuma, kungekhona kwinani elinye "elingcono".

I-Helix Angle: Isantya sokuFuduka ngokuchasene namandla angundoqo

I-angle ye-Helix yi-engile ejikelezayo yeflute elinganiswa ngokuchasene ne-axis ye-drill. I-helix ethe tye ityhala iitships ngaphandle ngokukhawuleza kwaye ifinyeza ubude bomphetho wokusika xa udibana nezinto nangaliphi na ixesha - kodwa ikwanyusa ukutyhala kwe-axial kwaye isuse izinto ezingaphezulu emzimbeni we-drill, nto leyo ebuthathaka umbindi. I-helix ethe tyaba igcina intsimbi engaphezulu embindini kwaye ibambe ngcono phantsi kwe-torque, kodwa iitships ziphuma kancinci, nto leyo eba ngumda wokwenyani xa umngxuma unzulu.

Yingakho i-engile ye-helix ifaniswa nohlobo lwe-chip endaweni yokuba ibekwe kwinani elinye. Ii-chips ezinde, ezithambileyo — uhlobo oluveliswa zizinto ezithambileyo okanye ezisebenzisekayo ngakumbi — zifuna i-helix eqinileyo ukuze ziqhubeke zihamba; ii-chips ezimfutshane, ezibuthathaka ezivela kwizinto ezinzima azidingi kutyhalwa okufanayo kwaye zizuza ngakumbi kumandla angundoqo ongezelelweyo e-engile engaphantsi. Akukho engile ye-helix "engcono" iyonke. Kukho i-engile kuphela ehambelana nendlela i-chip eyakheka ngayo.

Ubukhulu bewebhu: Ukuqina ngokuchasene negumbi le-chip

I-web yi-core eqinileyo ehla embindini we-bit, phakathi kwee-flute ezimbini. Inika i-drill amandla ayo okujika — amandla okumelana nokujija okanye ukuqhekeka phantsi kwe-torque enqumlayo. Ubukhulu be-web abuhlali buhamba kwi-bit; iyancipha ngabom, incinci kwincam kwaye ityebile ukuya kwi-shank, ngoko ke i-bit ifumana ukuqina kanye apho i-torque eqokelelweyo iphezulu khona.

Utshintshiselwano luthe ngqo: iwebhu eninzi ithetha amandla angakumbi, kodwa indawo encinci kwiflute ukuze iitships zihlale njengoko zihamba. Cinezela ubukhulu bewebhu kakhulu kwaye ubudlelwane buyaphela - xa iwebhu iwela malunga ne-40% yobubanzi bedrill, itshaneli yeflute eseleyo iba mxinwa kakhulu ukuba isuse iitships ngokuthembekileyo, kwaye umngcipheko utshintsha ukusuka "kwi-bit iyaguga" ukuya "kwi-bit jams and snaps." Le nkcukacha ayibonakali rhoqo kwiphepha le-spec, kodwa sesinye sezizathu eziqhelekileyo zokuba idrill iqhekeke ngaphakathi komngxuma endaweni yokuba ibuthuntu kwincam.

I-Flute esemgangathweni vs. I-Parabolic Flute: Iimpendulo ezimbini kwiNgxaki efanayo

Sivelisa zombini iintlobo zeflute, kwaye aziyonto "esisiseko" kunye "nephuculweyo" yedrill efanayo - zakhelwe imisebenzi eyahlukeneyo.

Iflute eqhelekileyo igcina umjelo omxinwa kunye newebhu ekhaphukhaphu, eyaneleyo kwiinjongo ezininzi zokubhola ngokubanzi: ubunzulu bemingxuma engaphantsi ukuya kwephakathi, umsebenzi oqhelekileyo wobude bemisebenzi, kunye nezixhobo ezingavelisi iitships ezinde, ezingalawulekiyo. Uninzi lokubhola lwemihla ngemihla luwela kolu didi, kwaye akukho nzuzo yokucacisa ngokugqithisileyo ngaphaya koko.

Iflute engumzekelo ivula loo mjelo. Udonga lweflute lugaywa lube yiprofayili ebanzi, egobileyo enika iitships indawo engakumbi kunye nendlela egudileyo yokuphuma, idibene ne-spiral ekhawulezayo ezihambisa ngamandla. Umjelo obanzi uthetha ukuba iwebhu engaphantsi nayo inokwenziwa ibe nkulu - malunga ne-25-50% yobubanzi bokubhola, xa kuthelekiswa malunga ne-12-25% kwiflute eqhelekileyo - ngoko ke i-bit ifumana amandla etships kunye namandla engundoqo ngexesha elinye, endaweni yokutshintshiselana enye ngenye. Loo nhlanganisela yiyo evumela iflute engumzekelo ukubamba imingxunya enzulu nakwizinto ezivelisa iitships ezinde, eziqhubekayo, kubandakanya intsimbi engagqwaliyo, ubhedu, kunye ne-aluminium, ngaphandle kokufuna ukugqobhoza umngxuma rhoqo.

Loo web ityebileyo iphakamisa i-axial thrust, yiyo loo nto ii-parabolic flute drills zihlala zidibene ne-split point - i-geometry efanayo ye-135° echazwe kwiNqaku 9 - ukubuyisela loo thrust kwinqanaba elilawulekayo.

Ngaphakathi komgca wethu we-parabolic, sikwabonelela ngobubanzi bee-groove ezimbini. I-V-groove enkulu ikhulisa igumbi le-chip kunye nesantya sokuphuma, esifanelana nezinto ezilukhuni kumatshini kodwa siza nentsimbi encinci engundoqo emva kwayo. I-V-groove encinci igcina intsimbi eninzi emzimbeni kwimisebenzi apho ubulukhuni bubaluleke ngaphezu komthamo ophezulu weflute. Yeyiphi omawuyisebenzise ixhomekeke ekubeni ingaba izinto okanye ubulukhuni bomsebenzi yeyona nto ithintelayo - hayi ukuba yeyiphi evakala iphucukile ngakumbi.

iflute esemgangathweni vs. iflute ehambisanayo

Kwenzeka ntoni xa iFlute ilahlekelwa yingxabano?

Xa i-geometry yeflute ingahambelani nezinto okanye ubunzulu bomngxuma, itshiphu iyayeka ukuhamba ngaphambi kokuba ifikelele phezulu kweflute. Ipakisha kwitshaneli endaweni yokuphuma kuyo. Ukusuka apho, ulandelelwano lokusilela luhlala lufana: iitshiphusi ezipakishiweyo zonyusa ukungqubana eludongeni lweflute kunye nodonga lomngxuma, ukungqubana kuvelisa ubushushu ngokukhawuleza kunokuba bunokunyamalala, kwaye umda wokusika uqala ukusika kwakhona izinto esele zisusiwe endaweni yesitokhwe esitsha. Iziphumo ezibonakalayo yibhore erhabaxa okanye enkulu, ukunyuka kwe-torque ngequbuliso, kwaye - ukuba ukupakishwa kukhulu ngokwaneleyo - kancinci okumayo kwaye kuqhekeke ngaphakathi komngxuma.

Le yindlela efanayo olu luhlu oluhlala lubuyela kuyo: umthengi akathengi nto yokubhola, uthenga ubuchule bokwenza imingxunya obuhlala buhleli. Uyilo lweFlute yindawo yokusilela okulula ukuyityeshela kuba iflute eqhelekileyo kunye neflute efana neparabolic zifana kwifoto. Umahluko ubonakala kuphela xa umngxuma unzulu ngokwaneleyo, okanye izinto zivelisa iitships ezinde kakhulu ukuba zingaphathwa ngumjelo omxinwa.

Oku kuthetha ukuthini xa uthelekisa ababoneleli

Akukho nanye kwezi zinto ethetha ukuba yeyiphi iflute “engcono.” Kuthetha ukuba yeyiphi iflute eyakhelwe umsebenzi ophambi kwakho. Xa uvavanya i-drill bit ngokuchasene nesicelo sakho sokwenyani, kufanelekile ukubuza:

•Bungakanani ubunzulu bomngxuma obucetywayo, kwaye ngaba iflute inomjelo ovulekileyo owaneleyo wokususa iitships kuloo bunzulu ngaphandle kokuzigqobhoza rhoqo?
•Ngaba ubukhulu bewebhu bulinganiswe ngokwezinto eziphathekayo — bunamandla aneleyo engundoqo ngaphandle kokuphazamisa itshaneli yetshiphu?
•Ukuba umthengisi unikezela ngeflute efana neyomfanekiso, ngaba idibene nendawo yokwahlulahlula ukulawula i-thrust eyongezelelweyo, okanye loo nkcukacha ishiywe ngaphandle?

Le yimibuzo ekuxelela ukuba ingaba iflute yenzelwe izinto zakho kunye nobunzulu bomngxuma, okanye iphawulwe nje ngayo.
