Thaum cov kws tsim kho tshuab tsim tshuab thawb cov ciam teb ntawm qhov siab - qhov chaw ceev, lawv thaum kawg tsoo lub raj mis: qhov hnyav - mus rau - nruj piv ntawm cov khoom txav. Txawm hais tias ntuj dub granite yog qhov kev xaiv zoo tshaj plaws rau cov tshuab nyob ruaj ruaj vim nws qhov loj thiab dampening, nws qhov hnyav tuaj yeem dhau los ua lub luag haujlwm rau siab - acceleration txav gantries lossis Z- axis spindles. Hauv cov xwm txheej no, cov khoom siv Ceramics siab heev- xws li Alumina (Al2O3) thiab Silicon Carbide (SiC)- tawm los ua lwm txoj hauv kev.
Nyuaj-rau-Qhov Ntsuas Qhov Ntsuas: Qhov Zoo Tshaj Ceramic
Rau siab -ceev scanning gantries, cov khoom zoo tagnrho yuav tsum nruj heev (kom tiv thaiv kev khoov hauv qab acceleration) tab sis lub teeb heev (kom txo qis lub cev muaj zog thiab tsim hluav taws xob). Cov kws ua haujlwm saib xyuas qhov nruj nruj, xam raws li Elastic Modulus (E) muab faib los ntawm qhov ntom ntom (d):
| Khoom siv | Elastic Modulus (GPa) | Qhov ceev (g / cm3) | Kev nruj nruj (GPa⋅cm3 / g) | Tus nqi txheeb ze |
| Ntuj Dub Granite | 95 | 3.1 | 30.6 | ★ (Lub hauv paus) |
| Alumina Ceramic (Al2O3 99%) | 370 | 3.9 | 94.8 | ★★★★☆ |
| Silicon Carbide (SiC) | 450 | 3.2 | 140.6 | ★★★★★ |
| Aluminium qauv | 70 | 2.7 | 25.9 | ★☆☆☆☆ |
Raws li cov lus qhia, Silicon Carbide muaj qhov tshwj xeeb nruj ze li tsib zaug siab dua li ntawmntuj granitelos yog aluminium. Qhov no txhais tau tias Silicon Carbide gantry beam tuaj yeem tsim kho kom lub teeb thiab nyias, tab sis flex zoo li xoom nyob rau hauv siab - nrawm nrawm.
Thermal Performance thiab Ib puag ncig
Thaum ntuj granite muaj cov khoom siv thermal zoo, Silicon Carbide nta tshwj xeeb thermal conductivity ua ke nrog CTE tsawg heev. Qhov no tso cai rau cov cua sov hauv zos (xws li los ntawm lub cev muaj zog) kom tawg sai sai thoob plaws tag nrho, tshem tawm cov thermal hotspots thiab tsis sib xws.
Kev Xaiv: Granite lossis Ceramics?
Thaum twg los lo nrog Precision Granite:
Nyob ruaj ruaj Machine Bases & Kem: Qhov hnyav hnyav yog qhov txiaj ntsig ntawm no, vim nws muab lub zog inertial thauj tog rau nkoj uas tiv thaiv sab nraud hauv pem teb kev co.
Tus nqi -Sensitive Precision: Ntuj granite yog tus nqi ntau dua - zoo rau cov chaw txua txiag zeb, tshuab, thiab ceg tawv, tshwj xeeb tshaj yog rau cov qauv loj.
Lub Sijhawm Lead luv: Cov qauv ceramic loj yuav tsum tau tshwj xeeb sintering qhov cub thiab pob zeb diamond dav - cov txheej txheem sib tsoo, ua rau lub sijhawm ua cov hmoov txhuas ntev dua.
Thaum twg los hloov kho rau Industrial Ceramics:
Siab-Kev nrawm nrawm: Txo qhov loj ntawm cov nqaj txav nrog cov ceramics txo qis kev siv hluav taws xob, lub cev muaj zog cua sov, thiab lub sijhawm voj voog.
Extreme Chemical / Vacuum Environments: Advanced ceramics muaj nyob ze -zero porosity thiab tiv taus cov plasma corrosive los yog tshuaj ntxuav cov tshuaj siv hauv wafer fabrication.
Siab -Kev Ua Haujlwm Kub: Ceramics tuaj yeem tiv taus qhov kub siab tshaj 1000℃yam tsis muaj kev cuam tshuam los yog nkag.
Kev sib koom tes tsim: Niaj hnub nimno ultra- cov tshuab precision feem ntau siv cov qauv tsim: hnyav, ruaj khov UNPARALLELED® Dub Granite Base ua ke nrog ultra- lub teeb, tawv Silicon Carbide (SiC) crossbeam. Qhov no muab qhov kawg tshuav nyiaj li cas ntawm stability thiab dynamic kev ua tau zoo.
