Thaum nws los txog rau kev tsim lub tshuab kho qhov muag tsis siv neeg, muaj ntau yam khoom siv tau. Ob ntawm cov ntaub ntawv no yog hlau thiab granite. Txawm hais tias ob qho tib si cov ntaub ntawv muaj lawv qhov zoo thiab qhov tsis zoo, granite feem ntau yog cov khoom siv rau kev ua kom pom tseeb thiab raug tsis siv neeg tshuaj xyuas tshuab. Nov yog qee qhov laj thawj vim li cas:
1. Rigidity thiab Stability: Granite yog ib yam khoom uas tsis tshua muaj zog thiab ntom, ntau denser dua hlau xws li txhuas lossis hlau. Qhov no muab nws zoo heev rigidity thiab stability uas yog ib qho tseem ceeb rau txhua lub tshuab uas yuav tsum tau precision thiab raug. Qhov rigidity thiab ruaj khov no kuj pab txo qis kev vibration thiab xyuas kom meej tias lub tshuab nyob twj ywm hauv qhov chaw thaum lub sijhawm ua haujlwm, uas yog qhov tseem ceeb rau kev ua tiav cov txiaj ntsig raug.
2. Tsawg Thermal Expansion: Granite muaj coefficient tsawg heev ntawm thermal expansion piv rau hlau xws li txhuas thiab hlau. Qhov no txhais tau hais tias nws tsis tshua muaj kev nthuav dav lossis kev cog lus vim qhov kev hloov pauv ntawm qhov kub thiab txias, uas tuaj yeem ua rau qhov tsis zoo ntawm kev ntsuas hauv lwm cov ntaub ntawv. Hauv kev tshuaj xyuas lub tshuab kho qhov muag, qhov tseeb yog qhov tseem ceeb, yog li kev siv cov khoom siv nrog thermal expansion yog qhov tseem ceeb kom ua tiav cov txiaj ntsig raug.
3. Kev tiv thaiv kev hnav thiab kev puas tsuaj: Granite tiv taus hnav thiab kev puas tsuaj uas ua rau nws yog ib qho khoom siv zoo tshaj plaws rau qhov chaw ntawm lub tshuab tshuaj xyuas qhov muag tsis siv neeg uas yuav tsum tau siv ntau zaus. Cov khoom no tseem tiv taus cov tshuaj thiab cov kuab tshuaj, uas ua rau nws yog qhov kev xaiv zoo tshaj plaws rau kev lag luam hnyav.
4. Muaj: Granite yog ib qho khoom siv ntau heev uas muaj nyob rau ntau qhov chaw hauv ntiaj teb. Qhov no txhais tau hais tias nws yog ib qho yooj yim mus nrhiav thiab qhov chaw tsim khoom ntawm lub tshuab tsis siv neeg kho qhov muag tshuaj xyuas. Qhov no yog qhov tseem ceeb vim nws pab kom tus nqi ntawm kev tsim khoom qis thiab ua kom lub tshuab tuaj yeem tsim tau sai thiab ua tau zoo.
5. Compatibility nrog Precision Manufacturing: Granite yog ib tug zoo tagnrho cov khoom rau precision manufacturing raws li nws yuav tsum machined rau siab heev kam rau ua. Qhov no yog ib qho tseem ceeb raws li lub tshuab kuaj xyuas qhov muag tsis siv neeg yuav tsum tau ntsuas qhov tseeb thiab qib siab ntawm qhov raug thaum tsim khoom. Vim nws qhov ntom thiab hardness, granite kuj txo qhov kev pheej hmoo ntawm deformation los yog warping thaum lub sij hawm machining, ua rau cov khoom kawg zoo dua.
Hauv cov ntsiab lus, thaum hlau tseem tuaj yeem siv los tsim lub tshuab kho qhov muag tsis siv neeg, granite feem ntau yog cov khoom siv vim nws qhov kev nruj nruj thiab kev ruaj ntseg, tsis tshua muaj thermal expansion, tsis kam hnav thiab puas, muaj, thiab compatibility nrog precision manufacturing. Qhov no yuav pab kom paub tseeb qhov tseeb thiab qhov tseeb uas yuav tsum tau muaj nyob rau hauv lub tshuab tshuaj xyuas qhov muag tsis siv neeg.
