Qhov kev ua tau zoo ntawm txoj kev qhia txiav txim siab qhov du thiab raug ntawm lub tshuab txav mus los. Cov kev qhia ntawm granite muaj cov coefficient qis ntawm kev sib txhuam thiab muaj zog tiv taus kev hnav. Piv nrog cov hlau qhia, lawv tuaj yeem txo qhov hnav ntawm cov khoom txav mus los thiab txo qhov zaus ntawm kev saib xyuas. Lub caij no, nws qhov kev ua tau zoo heev ntawm kev co tuaj yeem nqus tau qhov kev co thaum lub sijhawm ua haujlwm ntawm lub tshuab thiab txhim kho qhov zoo ntawm qhov chaw ua haujlwm. Hauv cov txheej txheem txiav ceev ceev, cov kev qhia ntawm granite tuaj yeem ua rau lub cuab yeej txiav nyob rau hauv lub xeev txiav ruaj khov, txo qhov roughness ntawm qhov chaw ua haujlwm, thiab txhim kho kev ua haujlwm zoo thiab cov khoom zoo.
4. Lub tshuab hluav taws xob tso tawm tshuab ua haujlwm
Thaum lub sijhawm ua haujlwm hluav taws xob, qhov kub thiab txias siab thiab kev cuam tshuam hluav taws xob raug tsim tawm, uas ua rau muaj kev xav tau siab rau kev ruaj khov thiab kev rwb thaiv tsev ntawm lub rooj ua haujlwm. Granite tsis yog tsuas yog muaj kev ruaj khov thermal zoo heev, muaj peev xwm tiv taus kev hloov pauv kub thaum lub sijhawm ua haujlwm, tab sis kuj muaj cov khoom rwb thaiv tsev ntuj thiab tsis cuam tshuam los ntawm kev cuam tshuam hluav taws xob. Yog li ntawd, cov rooj ua haujlwm granite tuaj yeem muab qhov chaw ua haujlwm ruaj khov rau kev ua haujlwm hluav taws xob, ua kom ntseeg tau tias kev ua tiav raug thiab qhov zoo ntawm qhov chaw.
II. Cov txiaj ntsig tseem ceeb ntawm Granite hauv CNC Numerical Control Equipment
Kev ruaj khov thermal zoo heev
Thaum lub sijhawm ua haujlwm ntev ntawm cov khoom siv CNC, muaj cua sov ntau heev, ua rau muaj kev nthuav dav thiab kev sib cog lus ntawm cov khoom siv. Tus coefficient ntawm thermal expansion ntawm granite yog qis heev (tsuas yog 4-8 × 10⁻⁶ / ℃), thiab nws qhov loj me tseem yuav luag tsis hloov pauv thaum qhov kub hloov pauv, uas tuaj yeem zam kev ua yuam kev thiab kev ntsuas kev hloov pauv los ntawm thermal deformation. Piv txwv li, nyob rau hauv qhov chaw kub siab, cov khoom siv CNC nrog cov hauv paus granite tseem tuaj yeem tswj tau qhov tseeb ntawm kev ua haujlwm ruaj khov, kom ntseeg tau tias cov khoom zoo tsis cuam tshuam los ntawm kev hloov pauv kub.
2. Kev ua tau zoo heev tiv thaiv kev co
Thaum lub sijhawm ua haujlwm CNC machining, kev ua haujlwm ceev ceev ntawm lub tshuab thiab lub zog txiav yuav ua rau muaj kev co, cuam tshuam rau qhov tseeb ntawm kev ua haujlwm thiab qhov zoo ntawm qhov chaw. Cov qauv siv lead ua tshwj xeeb hauv granite muab rau nws nrog kev ua haujlwm zoo heev, ua rau nws sai sai txo qis lub zog vibration sab nraud thiab txo qis kev cuam tshuam kev co. Cov ntaub ntawv sim qhia tau hais tias qhov piv ntawm damping ntawm granite tuaj yeem ncav cuag 0.05-0.1, uas yog 5-10 npaug ntawm cov khoom siv hlau. Nws tuaj yeem txo cov cuab yeej vibration thiab qhov nthwv dej ntawm qhov chaw ua haujlwm, thiab txhim kho qhov tseeb ntawm kev ua haujlwm thiab qhov tiav ntawm qhov chaw.
