Iimpawu ezisi-8 ze-twist drill kunye nemisebenzi yayo

Ngaba uyazi ukuba le migaqo: i-helix engle, i-angle yenqaku, umphetho ophambili, iprofayili yeflethi? Ukuba akukhange kubenjalo, kuya kufuneka uqhubeke ufunda. Siza kuphendula imibuzo efana: Yintoni umda wesibini wokusika? Yintoni i-ongix engix? Zichaphazela njani ukusetyenziswa kwesicelo?

Kutheni kubalulekile ukwazi ezi zinto: Izixhobo ezahlukeneyo zibeka iimfuno ezahlukeneyo kwesi sixhobo. Ngesi sizathu, ukukhetha i-twist parll enesakhiwo esifanelekileyo kubaluleke kakhulu kwisiphumo sokuqhuba.

Makhe sijonge izinto ezisibhozo ezisisiseko ze-twist parll: i-angle i-chan, umda wokusika, indawo yokusika i-chissel kunye nenqaku le-FORTE, iprofayile, kunye ne-Angle enqumlayo.

Ukwenzela ukufezekisa ukusebenza okukhulu kwezixhobo ezahlukeneyo, zonke iimpawu ezisibhozo kufuneka zitshintshelwe omnye komnye.

Ukubonisa ezi zinto, sithelekisa ezi zinto zintathu zilandelayo:

• I-twist rull nye 338, hss-e
• I-twist drolls hin 338, hsseli-com35
• I-twist dull din 338, HSS 4341

I-Angle yeNqaku

I-engile yenqaku ikwintloko ye-twist drill. I-angle ilinganiswa phakathi kwemiphetho emibini enqamlezileyo phezulu. I-angle yenqaku iyimfuneko ekuboleni i-twist ye-twill.

Incinci i-engile yenqaku, kokukhona lula ukuseka izixhobo. Oku kunciphisa umngcipheko wokutyibilika kwindawo egudileyo.

I-engle enkulu inqaku, elifutshane ixesha lokucofa. Nangona kunjalo, uxinzelelo oluphezulu luyafuneka kwaye ukulungiselela ukubakho kwezinto kunzima.

I-Geometricked ngokulandelelana, i-angle encinci ithetha imiphetho emide enqumlayo, ngelixa i-angle enkulu ithetha imiphetho enqabileyo.

I-cuts ecekeceke

Imiphetho ephambili yokusika ithatha i-on of the perlling. Imiphetho emide yokusika inomsebenzi ophakamileyo wokusika xa kuthelekiswa nemiphetho emifutshane yokusika, nokuba umahluko mncinci kakhulu.

I-twist drill ihlala inee-ophethi ezimbini eziphambili ezivunyiweyo ngumda we-chisel chisel.

Sika umda we-chisel

Umda we-chisel chisel iphakathi embindini we-drill ye-drill kwaye ayinasiphumo esisika. Nangona kunjalo, kubalulekile ukwakhiwa kwe-twist drill, njengoko inxibelelanisa imiphetho emibini enqamlezileyo.

Umda we-chisel chisel uxanduva lokungena kwezixhobo kunye noxinzelelo kunye nokuxabana kwezinto. Ezi ndawo, ezingenakuthelekiswa nanto kwiNkqubo yokuFunyanwa, kubangele ukwanda kwesizukulwana sobushushu kunye nokusetyenziswa kwamandla.

Nangona kunjalo, ezi mpahla zinokuncitshiswa ngokuthi "ukucofa".

I-Point Cuts kunye nenqaku lokukhetha

Inqaku lokunciphisa inqaku linciphisa umda we-chisel chisel ephezulu kwi-twist drill. Iziphumo zokucothisisa ekunciphiseni kakhulu kwimikhosi engxamisekileyo kwizinto kwaye ke kuncitshiswe amandla okutya.

Oku kuthetha ukuba ukuncipha yinto ethatha isigqibo sokugcina izibolo ezibonakalayo. Iphucula ukuphupha.

Ukuncitshiswa kwamanqaku ezahlukeneyo kumiselwa kwimilinganiselo ye-Din 1412 yeemilo. Ezona milo ziqhelekileyo ziyinto ephikisayo (imilo n) kunye nendawo yokuqhekeka (imilo c).

Iprofayili yeFlute (iprofayile yeGroove)

Ngenxa yomsebenzi wayo njengenkqubo yesiteshi, iprofayili yeflethi ikhuthaza ukubanjwa kwe-chip chip kunye nokususwa.

Iprofayile yeGroove, engcono ukufunxa i-chip kunye nokususwa.

Ukususwa kwe-chip ezihlwempuzekileyo kuthetha ukukhula okuphezulu kobushushu, okunokubuya kunokukhokelela ekuhambeni nasekupheleni kokutsala i-twill.

Iiprofayili ezibanzi ze-groove ziyisicaba, iiprofayili ezinamabala amancinci zinzulu. Ubunzulu beprofayili yeGroove ichaza ubukhulu becala le-dill. Iiprofayili ze-roove roove zivumela iidayimitha eziphambili ze-core. Iiprofayili ezinzulu ze-groove zivumela iidayimitha ezincinci (ezityebileyo).

Core

Ubungqingqwa bezinto eziphambili kukugqiba komgangatho wokuzinza kwe-twing rhasi.

I-twist idralls ene-ceameter enkulu (i-mught) ineendawo ezinozinzo eziphezulu kwaye ke zilungele iirroqui eziphezulu kunye nezixhobo ezinzima. Baye bakufaneleke kakhulu ukuba basebenzise iidrives zesandla njengoko zixhaphake kakhulu kwiindawo ezine-pickes kunye namandla alandelayo.

Ukwenzela ukuba kube lula ukususwa kweetshipsi ezivela kwi-Groove, ubukhulu becala buyenyuka kwi-dip ye-drill ukuya kwi-shank.

Ukukhokela i-champors kunye nenqanaba lokusika lesibini

I-charfles ezimbini zeSikhokelo zikwimibhobho. I-charfler yomhlaba kabukhali isebenza ngokongeza kwi-Borehole kwaye ixhase isikhokelo sokugqobhoza i-twill kwimngxunya eyomeleleyo. Umgangatho weendonga zodonga lwe-borehole nazo zixhomekeka kwiipropathi zesikhokelo se-chamfers.

Umda wesibini wokusika ucofa ukutshintsha okukhokela i-chamfers kwiprofayile yeGroove. Ikhulula kwaye inqumle iitshipsi ezinamathele kuloo nto.

Ubude be-chamflers yesikhokelo kunye nemiphetho yesibini yokusika ixhomekeke ikakhulu kwi-helix engle.

I-helix engle (i-spiral angle)

Inqaku eliyimfuneko le-twist drill yi-helix engle (i-spiral angle). Ichaza inkqubo yokwenziwa kwe-chip.

Ii-angles ezinkulu ze-helix zibonelela ngokususwa okusebenzayo kwezinto ezithambileyo, ezinde. I-helix encinci ye-helix, kwelinye icala, isetyenziselwa izixhobo ezinzima, ezimfutshane.

I-twist drolls ene-angle encinci kakhulu (10 ° - i-19 °) ine spiral ubude. Ngembuyekezo, i-twist drill swith i-helix enkulu ye-helix I-twist drills ene-spiel eqhelekileyo inesiphene se-Helix ye-19 ° - 40 °.

Imisebenzi yeempawu kwisicelo

Ekuqaleni, umxholo we-twist drills ibonakala ngathi inzima. Ewe, zininzi izinto kunye neempawu ezahlula-hlula i-twist drill. Nangona kunjalo, iimpawu ezininzi zixhomekeka.

Ukuze ufumane i-trill ye-twill elungileyo, ungazifumana kwisicelo sakho kwinyathelo lokuqala. Incwadana yemibhalo ye-D Drills kunye ne-Coltinks ichaza, phantsi kwe-Din 1836, ukwahlulahlulwa kwamaqela esicelo kwiindidi ezintathu n, h, kunye ne-W:

Kule mihla awuyi kufumana ezi ntlobo zintathu n, h, kunye ne-W emarikeni, kuba ekuhambeni kwexesha, iindidi zicwangcisiwe ngokwahlukileyo ukwenza iidrazi ezizodwa kwizicelo ezizodwa. Ngenxa yoko, iifom ze-hybrid zisekwa ukuba iinkqubo zothungelwano azikho mgangatho kwincwadi ye-din. Kwi-msk awuyi kufumana kuphela uhlobo lwe-N kodwa kunye neentlobo ze-Uni, i-UTL okanye VA.

Isiphelo kunye nesishwankathelo

Ngoku uyazi ukuba zeziphi iimpawu ze-twist ezigqwetha inkqubo yokuqhuba. Le theyibhile ilandelayo ikunika isishwankathelo sezinto ezibaluleke kakhulu kwimisebenzi ethile.

Ngokusisiseko, unokuchonga isicelo sakho kunye nesixhobo ofuna ukuqhuba ungene.

Thatha ingqalelo apho kunikezelwa ii-twist zetreyitha kwaye uthelekise iimpawu kunye nemisebenzi oyifunayo yezaxhobo zakho zinxitywe.
