Peb txhua tus paub tias pob zeb diamond sib tsoo lub log tuaj yeem ua cov ntaub ntawv nyuaj, thiab yog li ntawd lawv feem ntau siv yam tsis muaj hesitation. Txawm li cas los xij, qee cov neeg siv khoom tau pom cov kab nrib pleb tshwm hauv lawv lub log sib tsoo thaum siv. Dab tsi ua rau qhov no?
Yog vim li cas rau tawg nyob rau hauv pob zeb diamond sib tsoo log:
1. Nto txiav cov kab nrib pleb feem ntau yog tshwm sim los ntawm qhov kub siab tshaj tam sim no nyob rau hauv cheeb tsam txiav kev sib cuag thaum lub sij hawm txiav, ua rau qhov ntiav compressive kev nyuaj siab faib rau ntawm qhov chaw txiav thiab qhov siab tensile siab tshaj qhov tseem ceeb nyob ze ntawm qhov chaw tshaj qhov tensile lub zog ntawm cov khoom. Yog li ntawd, thaum lub sij hawm txiav, lub cim ntawm instantaneous kub kub yuav tsum tau txo thiab tiv thaiv, yog li txo thiab tiv thaiv tiam ntawm residual tensile kev nyuaj siab.
2. Tsis tsuas yog yuav tsum tau txiav cov kab nrib pleb yuav tsum zam, tab sis kuj txiav hlawv. Thaum lub sij hawm ua cov pob zeb diamond, qhov kub ntawm lub cuab yeej tam sim no nyob ntawm txoj kev ua, cov yam ntxwv ntawm cov cuab yeej pob zeb diamond, thiab cov kev txiav.
3. Qhov ntau dua qhov nrawm nrawm thiab axial txiav ceev ntawm lub pob zeb diamond sib tsoo lub log, lub log hardness siab dua, qhov zoo dua qhov me me, qhov qis thermal conductivity ntawm cov khoom siv, thiab qhov loj dua lub log hnav, qhov siab dua qhov kub yuav nce, ua rau nws yooj yim rau txiav cov kab nrib pleb thiab sib tsoo kub.
Kev daws rau cov kab nrib pleb hauv pob zeb diamond sib tsoo log:
1. Thaum hnav lub log sib tsoo siv nws sab, kev ua haujlwm yuav tsum tau ua raws li kev cai. Tsis txhob siv sab ntawm lub log sib tsoo rau kev hnav khaub ncaws. Xyuas seb qhov sib tsoo lub log sib dhos tsis raug.
2. Tshawb xyuas thiab kho lub tshuab cuab yeej spindle los txhim kho nws cov precision.
3. Thaum hloov lub log sib tsoo, nco ntsoov xaiv lub pob zeb diamond sib tsoo lub log nrog qhov loj tib yam li cov ncej thiab siv cov sib tsoo cov log ntawm tib yam tshwj xeeb.
4. Ua raws li cov lus qhia nruj me ntsis lossis cov pob zeb diamond sib tsoo log neeg siv phau ntawv kom raug txiav ua haujlwm.
Pob zeb diamond sib tsoo log tseem hu ua superhard sib tsoo log. Raws li cov lus hais mus, tej yam uas nyuaj heev yog nkig, tshwj xeeb tshaj yog ceramic pob zeb diamond sib tsoo lub log, qhov twg cov binder yog ceramic (iav), uas yooj yim heev rau tawg. Yog tias cov khoom siv hlau tawg, feem ntau yog vim muaj kev cuam tshuam thaum siv. Yog hais tias lub fused txheej tawg vim yog vim li cas lwm yam tsis muaj kev cuam tshuam, nws feem ntau yog vim tsis zoo tswj kub thaum lub sij hawm tsim khoom, ua rau tsis sib xws. Yog hais tias lub fused txheej tsis zoo sib raug zoo rau cov khoom siv hauv paus lossis cov txheej txheej tawm, nws yog vim qhov tsis sib xws ntawm cov nplaum thaum tsim khoom lossis kev cuam tshuam tsis txaus ntawm cov hniav serrated ntawm cov khoom siv hauv paus. Cov txheej me me tuaj yeem kho tau ntawm lub hoobkas; kev puas tsuaj loj yuav tsum tau hloov.
