Uthotho: Kutheni ii-Drill Bits zingaphumeleli | Inqaku le-13
Amagama angundoqo: i-strill bit yokugrila ngobuchule, ukunyamezelana kwe-drill bit epheleleyo, ukunyamezelana kwe-h8 drill bit, i-drill bit back taper, i-web taper, i-drill bit margin grinding, i-drill bit surface finish, i-drill bit consistency batch drill, i-interference fit drill, i-reaming tolerance

Inqaku lokugqibela kolu ngcelele lijonge iindlela ezimbini ezahlukeneyo zokufaka iflute kwisiqwenga sentsimbi — enye esusa izinto, enye engazange ikwenze oko. Le ithatha inyathelo eliya phambili. Iziqwenga zomhlaba ezipheleleyo zenziwe ngokusila, kodwa "umhlaba" awungomsebenzi omnye. Zininzi, nganye ilawula ubukhulu obahlukileyo. Eli nqaku lijonga ukuba zeziphi ezo milinganiselo, kunye nendlela ezithwala ngayo ukuya kumngxunya umthengi agqibela enawo.

Oko Abathengi Bakukhathaleleyo Ngokwenene

Abathengi abasoloko bebuza ukuba zingaphi iipasi zokusila ezidlule kuzo. Eyona nto bayibuzayo kukuba ingaba imingxunya abayigqobhozayo iya kuba nobukhulu obufanayo na, nokuba iqela elilandelayo liya kusebenza ngendlela efanayo nale, kwaye ingaba i-bit inokuxhasa na umsebenzi ongaphantsi komsinga ofana nokucofa, ukuxovula, okanye ukucinezela. "Umhlaba opheleleyo" awuphenduli nayiphi na yale mibuzo ngokwawo - uchaza kuphela inkqubo. Oyena mphumo uchaza ukuba le nkqubo ibamba ziphi izilinganiso, kwaye iqine kangakanani.

Ukusila Akulawuli Ubungakanani Obunye — Kulawula Uthotho Lwazo

Inxalenye epheleleyo yokugaywa ayibumbeki ngendlela enye. Idlula kwimisebenzi eyahlukeneyo yokugaywa, nganye ibambe ubukhulu obahlukileyo:

Ububanzi bangaphandle kunye nokusila komda kugqiba ukuba i-bit ihlala rhoqo ngaphakathi kwe-standard tolerance band — ukunyamezelana kobubanzi obuqhelekileyo kwishishini kwi-twist drills yi-h8, inkcazo yehlabathi, ayiyonto eyenziwa yifektri nganye ngokwayo. Indlela olu sebenzi oluqhutywa ngayo ibonakala ngokuthe ngqo kwi-radial runout ye-bit xa sele itshixiwe.

I-Back taper: ububanzi bangaphandle buyancipha kancinci ukusuka kumphetho wokusika ukuya emgongxweni. Le tape igqunywa ngabom ukuze kuncitshiswe ukungqubana nobushushu phakathi komda nodonga lomngxuma. I-back taper encinci kakhulu kwaye i-bit inokubopha emngxunyeni; ininzi kakhulu kwaye ilahlekelwa yisikhokelo, nto leyo evumela umngxuma ukuba uphume embindini. Ukusila kungabamba olu bukhulu ngokuchanekileyo - i-roll forged bit ngokubanzi ayinakukwazi, kuba kuxhomekeke kwimeko yee-rolling dies, ezigugayo kwaye zikhukulise ngaphakathi komjikelo omnye wemveliso.

I-Web taper: ubukhulu be-core buyanda ukusuka kwincam ukuya kwi-shank ukuze kongeze ukuqina komzimba we-bit, ngaphandle kokuthatha indawo eninzi kangangokuba i-chip evacuation iyahlupheka. Le yenye indlela ebekwe ngokuzimeleyo ekugayweni, kwaye yiyo egqibayo ukuba i-bit iyajika - okanye iyaqhekeka - kancinci kumngxuma onzulu.

Ulungelelwaniso lweFlute-to-flute: kwi-full ground bit, iiflute ezimbini ziyacolwa ngokwahlukeneyo. Ukuba i-wheel dressing okanye ii-feed parameters ziyashukuma phakathi kwezi zimbini, iiflute ziphuma zingalingani kancinci. Oku kunxulumene — kodwa kwahlukile kwi — point centering, esikugubungele kwiNqaku 9 kwi-135° split point. Kwane-ground point angle echanekileyo ayizukuhlawula ngokupheleleyo iiflute ezingalinganiyo; i-bit iya kuqhubeka isebenza ngokungalingani okuncinci.

Ukugqitywa komphezulu kukwayinto elawulwayo

Umphezulu womhlaba uthambile kunowokugoqwa okanye oqiniweyo. Lo asingomahluko nje kuphela wobuhle — umphezulu weflute othambileyo unciphisa ukumelana nokuhamba kweetships kwaye unciphisa ukuthambekela kweetships zokuwelda okanye ukupakisha ngaphakathi kweflute. Isiphumo sibonakala kakhulu kwizinto ezithambekele kumphetho owakhelwe phezulu, njengentsimbi engagqwaliyo kunye netitanium, apho ibonakala khona ngqo kubomi bezixhobo.

Umhlaba Opheleleyo Uphakamisa Isilingi — Akuqinisekisi Isiphumo

Le ngongoma ibalulekile: inkqubo epheleleyo yomhlaba ibeka umda ophezulu wokuba ngokuchanekileyo okunokufezekiswa. Ayiqinisekisi ukuba yonke ibhetshi iyafikelela kuyo. Iibhithi ezimbini zinokuba yi-full ground kwaye zisebenze ngokwahlukileyo, kuba:

•Ivili lokusila elingafakwanga ngexesha elifanelekileyo liya kuphuma kancinci kancinci kwiprofayili yalo.
•Ngaphandle kokuhlolwa kwenkqubo, ukuhambelana kwebhetshi ukuya kwibhetshi akujongwa ngokwenene. Kwimigca yethu, abaqhubi benza uhlolo lokuqala ekuqaleni kwebhetshi nganye - kuqinisekisa ububanzi bangaphandle kunye nokubaleka komhlaba wokuqala - kulandelwa luhlolo oluqhubekayo ngexesha lokuqalisa, endaweni yokufumana ukushukuma okulinganayo kuphela emva kokuba yonke ibhetshi igqityiwe.
•Imeko kunye nokugcinwa kwezixhobo zokugaya ngokwazo kugqiba ukuba ngaba ipharamitha yokugaya emiselwe kakuhle ingena ngaphakathi kokunyamezelana ekusebenzeni.

Ngamanye amazwi, "siphelele, ngoko ke sichanekile" siphendula umbuzo wenkqubo, kungekhona umbuzo wokuhambelana. Yiyo loo nto abathengisi ababini banokubhala "isiseko esipheleleyo" kodwa banike iziphumo ezahlukeneyo kakhulu.

Oko Kuthethwa Ngala Maqondo Kwimisebenzi Yomthengi Ephantsi

•Imingxunya engaphambi kokuthepha: ukunyamezelana kobubanzi bemingxunya kumisela ipesenti yokubandakanyeka komsonto. Inkulu kakhulu kwaye ukubandakanyeka akwanelanga; incinci kakhulu kwaye ukwaphuka kwempompo kuba yingozi.

•Ukuphinda-phinda: isibonelelo sesitokhwe se-reamer sibalwa ngokumalunga nokunyamezelana kwangaphambi komngxuma. Ukuba umngxuma ogqojoziweyo ngokwawo uyahluka ukusuka kwisiqwenga ukuya kwisiqwenga, ubomi bokuphinda-phinda kunye nokuchaneka kokuphinda-phinda kuyachaphazeleka.

•Imingxunya ye-dowel pin kunye nokulingana kokuphazamiseka: ukulingana kokuphazamiseka kuhlanganisa iindawo ezimbini ngokwenza i-shaft ibe nkulu kancinci kunomngxuma, ngoko ke ukulingana koxinzelelo kuvelisa ukuguqulwa kwe-elastic kunye nokungqubana okuvalela iindawo endaweni ngaphandle kwezinto zokubopha ezongezelelweyo. Ukuphazamiseka kudla ngokuba zii-microns ezimbalwa ukuya kwezilishumi elinesibini kuphela, ngoko ke ukuba umngxuma uphuma umkhulu kakhulu ukulingana akuyi kubamba; mncinci, kwaye ukulingana koxinzelelo kunokuqhekeza indawo. Le yenye yezona mfuno ziqinileyo zokuqina umngxuma obotshiweyo onokucelwa ukuba uhlangabezane nazo.

•Ukubhola nge-jig bushing-guided: ukulingana phakathi kobubanzi bomda we-bit kunye ne-bushing bore kuqinisekisa ukuba i-bushing iyaguga ngokukhawuleza kangakanani, kunye nokuba indawo yomngxuma ihlala ihambelana na kwisixhobo esinemingxuma emininzi.

Oku kuthetha ukuthini xa uthelekisa ababoneleli

"Umhlaba opheleleyo" uphendula indlela eyakhiwe ngayo iqhekeza — hayi ukuba loo ngcaciso iphindaphindwa ngokuthembekileyo na. Ngaphambi kokuthelekisa iikowuteshini, kufanelekile ukubuza ngokuthe ngqo:

•Ngaba i-drill ingagaywa ukuze ifikelele kumlinganiselo we-h8?
•Ngaba i-back taper kunye ne-web taper zibekwe kumgangatho omiselweyo?

Umgangatho wokugaya akufuneki uthathwe njengowomthengisi kuphela. Umthengi angayijonga inxalenye yayo ngokuthe ngqo: bamba iqhekeza phezulu ekukhanyeni aze ajonge umphezulu weflute kunye nomphezulu we-margin. Amanqaku okugqiba alinganayo, ahambelanayo okugaya okuzinzileyo; amanqaku abonakalayo okuthetha okanye uburhabaxa obungahambelaniyo kuyafaneleka ukubuzwa.
