Lub tshuab muaj zog precision yog siv hauv kev lag luam los ua cov khoom ua haujlwm. Lawv yog tus cwj pwm los ntawm kev kub ceev ntawm kev sib hloov ntawm cov cuab yeej txiav, uas tso cai rau kev ua tiav cov khoom mus rau qhov xav tau qhov ntev. Tab sis nws yog tsis yooj yim sua kom ua raws li cov hauj lwm zoo yam tsis muaj nozzles uas phim lawv cov yam ntxwv.
Cov khoom siv niaj hnub, txawm tias cov cuab yeej hlau, tsis tas yuav tiv taus qhov siab tshaj plaws, yuam cov tswv lag luam nrhiav cov khoom siv zoo dua. Txhawm rau daws qhov teeb meem no, CBN cutters, lossis cov ntxig ntxig, ua kom muaj kev ntseeg siab ntawm cov txheej txheem tseem ceeb thiab ua kom muaj txiaj ntsig ntawm kev ua haujlwm ntawm cov khoom ua haujlwm.
Cov ntaub ntawv dav dav txog Elbor
Cov khoom siv nrov tshaj plaws siv hauv kev tsim khoom ua ntu txiav yog pob zeb diamond. Nws muaj cov qib siab hardness, tuaj yeem tiv taus hnyav thiab ruaj khov. Nyob rau hauv lem, elbor muaj peev xwm ua raws li ib tug lwm txoj rau ib tug natural ntxhia. Nyob rau hauv cov nqe lus ntawm txhua yam khoom, nws yog xyaum tsis inferior rau pob zeb diamond, thiab nyob rau hauv cov nqe lus ntawm hardness nws yog 3-4 lub sij hawm superior rau tsoos abrasive consumables. Nyob rau tib lub sij hawm, elbor li xws li yog tsis tag nrhocuab yeej txiav.
Lub workpiece yog tsim los ntawm prefabricated, ib feem tseem ceeb ntawm cov khoom siv thiab cov cuab yeej steel. Thaum kawg ntawm cov ntsiab lus, elbor daim hlau rau cutters yog tsau, uas ncaj qha ua txhua yam abrasive nkaus. Cov no yog cov ntxig raws li cov muaju, uas yog cubic boron nitride. Cov duab thiab qhov loj ntawm daim phiaj overlay yuav txawv nyob ntawm qhov kev siv thiab tsim ntawm cov cab kuj.
Kev ua tau zoo ntawm cov khoom siv CBN
Txawm tias tawm tsam keeb kwm ntawm carbide thiab ntxhia-ceramic cutters, cov khoom siv thiab lub cev ntawm CBN yog qhov zoo heev. Suffice nws hais tias nws tuaj yeem pom machining tsis kam ob peb zaug siab dua li cov ntaub ntawv hais saum toj no. Qhov no tso cai rau, piv txwv li, ntawm lub spindle ceev ntawm txog 500 m / min, kho cov workpieces ua los ntawm cam khwb cia hlau. Qhov no yog li cas ntxhib mechanical finishing yog manifested, tab sis elbor cutters kuj yuav siv tau nyob rau hauv lub kawg tsim ntawm contours ntawm qhov chaw.
Los ntawm txoj kev, qhov tob ntawm kev tshem tawm ntawm txheej txheej tuaj yeem ncav cuag 0.1-0.2 hli. Lub peev xwm txiav ntau ntawm CBN sib txawv hauv qhov kev siv zog tsawg yog xav tau los ntawm lub tshuab ua kom tiav. Ntawm qhov tod tes, qhov no ua rau nws muaj peev xwm ua tau zoo tiv thaiv cov alloys nyuaj, thiab ntawm qhov tod tes, siv nyiaj tsawg kawg nkaus ntawm cov peev txheej ntawm lub zog hauv kev pabcuam tsis tshua muaj teeb meem workpieces.khoom siv. Txo cov kev xav tau rau lub zog muaj peev xwm yog vim qhov peculiarities ntawm kev sib cuag ntawm CBN nrog rau saum npoo ntawm lub workpiece.
Yam ntxwv ntawm CBN cutters raws li GOST
Cov qauv tsim thiab cov yam ntxwv ntawm qhov seem yog ua raws li cov qauv dav dav txuas nrog cov ntsiab lus nrog cov lus qhia pob zeb diamond. Tshwj xeeb, koj tuaj yeem tsom mus rau GOSTs hauv ntu 13288 thiab 13297-67. Raws li cov kev cai, qhov ntev ntawm cov khoom yuav txawv ntawm 40 mus rau 125 hli. Nyob rau hauv rooj plaub no, cov kauj ruam yuav yog 20 hli - uas yog, muaj consumables rau 40, 60, 80 mm, thiab lwm yam nyob rau tib lub sij hawm, qhov ntev ntawm lub workpiece nws tus kheej txawv ntawm 10 mus rau 40 mm - qhov ntsuas no kuj txiav txim siab. txoj kab uas hla ntawm lub hauv paus ua haujlwm, uas yog lub elbor cutter. GOST qhia tias lub thickness ntawm lub puab txheej ntawm ib feem yuav tsum yog los ntawm 6 mus rau 12 hli. Tag nrho txoj kab uas hla txawv ntawm 10 mus rau 40 mm. Ntawd yog, nws tuaj yeem ua cov ntsiab lus nyias rau kev sib tsoo zoo, thiab cov cutters loj heev rau kev kho qhov chaw ntxhib ntawm cov duab.
txheej txheem txheej txheem
Txhawm rau tswj xyuas qhov ua tau zoo, nws yog qhov tsim nyog los tsim cov xwm txheej tshwj xeeb raws li cov khoom siv tuaj yeem muab cov txiaj ntsig zoo. Nws raug nquahu kom siv cov cutters thaum tsis muaj kev vibration cuam tshuam thiab cov nyhuv ntawm kev ntaus. Kev vibration siab amplitude tuaj yeem ua rau cov hlua khi.
Ib qho ntawm cov khoom siv ntau tshaj plaws ntawm hom no yog ib qho elbor tho txawv cutter, los ntawm qhovua tiav qhov kawg ntawm qhov khoob ua los ntawm cov hlau tawv tawv. Hauv cov haujlwm zoo li no, cov kws tshaj lij qhia ua haujlwm ntau theem hauv ntau hom. Raws li, nyob ntawm qhov yuav tsum tau ua rau qhov kawg tshwm sim, kev sib txawv ntawm kev sib tsoo thiab kev sib tsoo zoo yog siv ntawm qhov ceev ntawm 60-80 m / min. Thaum ua hauj lwm nrog ob peb lub dav hlau, nyob rau hauv uas nws kuj yog npaj los ua qhov rau lub bushings, nws yog pom zoo kom ua ntej bore thiab ces pib drilling.
tawm tswv yim zoo ntawm ntu
Hauv kev xyaum, cov neeg ua haujlwm ntawm cov cuab yeej siv tshuab tau muab nrog CBN qhov chaw nco txog qib siab ntawm kev ua haujlwm ntev nrog kev ua haujlwm zoo ntawm cov khoom ua haujlwm. Nyob rau lub sijhawm luv luv (piv rau cov tshuab txiav tsoos), cov neeg siv tau txais cov khoom ntawm qhov xav tau, tsis hais cov khoom siv hauv paus.
Cov txiaj ntsig ntawm kev siv cuab yeej ntawm kev saib xyuas kuj tau qhia. Qhov no yog rooj plaub thaum lub cuab yeej muaj qhov cuam tshuam rau tus kheej. Ntawd yog, CBN cutters khaws lawv cov kev ua haujlwm zoo, tsis tas yuav tsum tau kho cov duab tshwj xeeb. Vim li no, qhov kev pheej hmoo ntawm kev poob qhov xav tau cutter geometry vim hnav tsis raug raug tshem tawm. Nyob rau tib lub sijhawm, cov neeg ua haujlwm tseem hais txog qhov tsis muaj qhov xav tau los saib xyuas kev tswj xyuas qhov kub thiab txias ntawm qhov txiav. Cov khoom siv tuaj yeem tiv taus kev ntxhov siab, yog li dej txias yuav tsis siv.
Kev tshuaj xyuas tsis zoo
Vim elbor twb xub tsim los uacov ntaub ntawv rau sharpening, noj mus rau hauv tus account tag nrho cov nuances ntawm cov txheej txheem thev naus laus zis, tsis muaj kev thuam ntawm nws qhov kev ua tau zoo. Puas yog nws tsim nyog sau cia qhov tsis ntseeg ntawm cov neeg tig mus rau cov txiav nrog cov overlays xws li.
Yog hais tias nyob rau hauv cov nqe lus ntawm kev ua tau zoo ntawm cov abrasive kev txiav txim siab tag nrho lawv tus kheej, ces cov qauv tsim qhia qee yam kev txwv ntawm kev siv cov ntsiab lus. Tab sis qhov no siv tsis tau rau CBN inserts rau cutters, tab sis kuj rau pob zeb diamond counterparts.
Teb daim ntawv thov ntawm cov khoom siv elbor
Cov khoom siv no yog siv hauv yuav luag txhua qhov chaw ntawm kev lag luam hlau. Nyob ntawm qhov tshwj xeeb ntawm kev lag luam, cov cuab yeej tuaj yeem ua kom zoo, kho kom zoo, sib tsoo, thiab lwm yam. Nws yog ib qho tseem ceeb uas yuav tsum tau hais tias, tsis zoo li ntau cov khoom siv rau kev ua hlau, lub elbor tig cuab yeej zoo copes nrog ob qho tib si ua ntej thiab zaum kawg ntawm cov khoom.. Raws li qhov ntau ntawm cov khoom siv rau kev ua haujlwm, lawv suav nrog tsis yog tsuas yog cam khwb cia hlau thiab hardened steels, tab sis kuj mineral-ceramic high-strength blanks.
Zaj lus
Cutters ntawm hom no, tau kawg, tsis pom zoo siv rau feem ntau cov dej num hauv kev ua cov hlau nrog qhov nruab nrab hardness. Ntxiv mus, mos alloys tuaj yeem deformed nrog cov cuab yeej zoo li no. Yog li ntawd, nws yog tsim nyog tham txog qhov nqaim tshwj xeeb ntawm lub elbor cutter. Tus nqi ntawm qhov ntsuas kuj txwv nws txoj kev siv - ntawm qhov nruab nrab 1,5-2 txhiab rubles.
Pom tseeb, tsis tas yuav muab cov qauv hauv tsev ntawm lub tshuab dhos nrog cov khoom siv li no. Txawm li cas los xij, nrog kev poob ntawm cov khoom ua haujlwm ntawm cov pa carbide cutters, tus neeg siv tsuas yog yuav tsum tau tig mus rau cov tuam txhab muab cov kev pabcuam elbor sharpening. Yog tias peb tham txog lwm txoj kev xaiv, ces qhov ze tshaj plaws yuav yog tib lub pob zeb diamond cutter. Nws yog ntau yoog raws cov dej num ntawm kev ua cov khoom siv hlau sib txawv ntawm cov hardness. Tab sis nyob rau hauv cov nqe lus ntawm kev ua hauj lwm zoo nyob rau hauv relation mus high-strength ntom workpieces, pob zeb diamond seem poob rau elbor sawv daws yuav.
