Txiav yog ib hom kev xyaum nrog sib sib zog nqus ua rau cov khoom siv los ntawm nplhaib txiav. Tus txheej txheem nesting yuav tawm hauv tus cag, txuag khoom thiab txo lub hwj huam noj ntawm cov cuab yeej siv twj. Thaum nws tsim nyog los coj cov qauv ntawm qhov chaw khoom siv rau kev xeem, kev siv lub tes tsho tes tsis tuaj yeem hloov los ntawm lwm cov cuab yeej. Kev siv lub nplhaib yog siv los ua cov txheej txheem hla 60 hli inch, thiab qhov tob ntawm qhov chaw muaj peev xwm ncav tau ntau tshaj kaum lub hli.
Muaj ob hom trepanning:
ib tug yog ntim sab nraud tshem tawm thiab lwm yam yog sab hauv nti tshem tawm (saib qhov tob qhov qhwv). Qhov zoo ntawm qhov kev sib txuas ntawm lwm tus ntiv tes xoo tho txhais tau tias cov cuab yeej ntawm cov kua nruab nrog cev yog yooj yim, tiam sis txoj kab uas hla cov yeeb nkab yog me me, yog li lub zog thiab kev sib zog ntawm cov yeeb nkab yog cov neeg pluag, thiab nws yog siv nyob rau hauv tsawg cov khoom me me.
Kev tshem tawm ntawm kev ntim thaij sab nrhau tawm ntawm lub siab ntawm cov kua dej ntub dej tawm los ntawm cov yeeb nkab, ces nws xav tau cov khoom siv dej ntau dua thiab daws qhov teeb meem, tab sis qhov tsim tau siab, thiab nws tsim nyog rau batch ntau lawm.
Tus trepanning yuav muaj ib los yog ntau dua kev ceev fais fab los yog cav txiav kheej, thiab lub tshuab ntuag ntsev yog nruab nrog cov kev taw qhia kom tiv thaiv kev co thaum lub sij hawm txiav thiab txo qhov deflection. Phau ntawv qhia thaiv yog ua ntawm cemented carbide, bakelite los yog nylon. Lub cav ntuag thiab lub qhov kav hlau tubular siv tau los txuas los ntawm cov khoom siv los yog cov xov xwm tshwjxeeb. Yuav kom paub tseeb tias qhov kev tshem tawm ntawm chips thiab txo txiav load, qhov txiav sawv ntawm txhua lub cuab tam lub taub hau ntawm trepanning yog tsim nyob rau hauv ntau daim, thiaj li hais tias lub chips yuav muab faib narrowly. Nyob rau tib lub sijhawm, tus chip breaker rubbed nyob rau hauv ntawm txhua tus hniav kom tawg lub chips. Rau qhov loj ntawm lub qhov muag tsis pom qhov chaw, qhov tshwj xeeb txiav khoom yuav tsum cais cov hauv paus ntawm lub cev.
Khoom siv drilling sib sib zog nqus qhov txawv tseem ceeb xim - tob qhov ua lag luam tuaj qhia koj:
1: Thaum pib los ntawm drilling, lub tshuab txiav yuav tsum qis qis thiab lub ntug ntawm lub hau yuav tsum kov lub phaj hlau qeeb. Thaum lub me ntsis drilled mus txog 1-2 hli, lub tshuab txiav yuav pub txhua zaus tom qab tswj kev pub.
2: Thaum drilling, lub zog yuav tsum tsis txhob muaj zog los yog tsawg dua, qhov kev quab yuam yuav tsum muaj qhov nruab nrab thiab qhov pub yuav tsum hnav.
(1) Ntau lub zog thiab cav load yuav cuam tshuam rau lub neej txoj haujlwm ntawm lub tshuab thiab nti raug tshem tawm tib lub sijhawm.
(2) Yog tias lub zog qis dhau lawm, txoj kev txhuam ntawm ntug kev yuav nce siab thiab qhov kev hla kev tawm ntawm lub ntsis yuav tsum ceev.
(3) Qhov tsim nyog tuab ntawm hlau chips yog 0.10-0.15 mm.
3: Thaum nce lub nrawm, kev ceev noj yuav tsum tau qis qeeb kom tsis txhob muaj kev txav mus rau qhov tob tob, qhov kev puas ntawm cov hniav thiab cov hau kev sib tw.
4: Nyob rau hauv cov txheej txheem ntawm qhov drilling, yuav muaj tshwm sim rau sab nraud, uas tuaj yeem tshwm sim los ntawm ntau qhov kev quab yuam lossis kev ua haujlwm ntawm cov me me, kev siv tawv thiab qhov muag ntawm cov khoom ua haujlwm, impurities, cov voj voog khiav thiab lwm yam. 5: Chips manifestation: tsis txawv txav thaum drilling, co ntawm tes, nce ntawm lub cev load thiab lwm yam phenomena
Cov Kev Khiav Haujlwm:
1) Rov qab riam rau hauv lub sijhawm thiab ntau zaus kom cov thawv ntim thiab thev xa hluav taws xob tuaj yeem tso tawm.
2) Tshem tawm cov npog ntsej muag hlau nrog hooks hauv lub sij hawm (tsis muaj (tsis muaj tes, tsam khawb)
3) Xyuas seb qhov me ntsis yog kis tau thiab hloov qhov me ntsis rau hauv lub sijhawm.
4) Yog tias tsis muaj kev tshem tawm ntawm cov khoom plias tshem tawm thiab kev plias tshem tawm tsis pauv, nws yuav yooj yim rau cov khib nyiab thiab cov tub ntxhais yuav tsum tau txav, uas yuav ua rau tshwm sim ntawm ntsis ntug pob thiab tawg.
