Mechanical contact yog tus yeeb ncuab ntawm nanometer precision. Cua Bearings ntawm Precision Granite lossis Ceramic guides tshem tawm kev sib txhuam, hnav, thiab kev co. Nrog rau ib txwm ya-qhov siab ntawm 5-10 μm thiab xoom- kev sib txhuam txav, cov tshuab no ua rau 10 nm daws teeb meem xav tau rau qib siab semiconductor lithography thiab high-end metrology.
1. Tshem tawm kev sib txhuam: Txoj kev mus rau lub neej uas tsis muaj kawg
Vim tias tsis muaj kev sib cuag ntawm lub cev ntawm cov khoom txav, huab cua cov kabmob muaj qhov tsis zoo. Qhov no ua kom ntseeg tau tias qhov kev ntsuas thawj zaug ntawm lub scanning theem tseem siv tau rau xyoo. Nyob rau hauv siab - lub voj voog lub luag haujlwm ib puag ncig zoo li wafer scanning, "lub neej tsis kawg" no txo cov nqi tu thiab tshem tawm qhov xav tau ntawm lubrication, uas yog qhov tseem ceeb rau kev ua raws li chav huv.
2. Ua tiav Sub-Micron ncaj nraim hla kev mus ncig ntev
When an air bearing glides over a DIN 876 Grade 000 granite guide, it averages out the microscopic surface irregularities. This "averaging effect" results in motion straightness that is often superior to the physical guide itself. For long-travel applications (>1000mm), qhov no tso cai rau kom muaj qhov sib npaug ntawm cov lus tsa suab nrog qhov yuam kev tsawg kawg nkaus (pitch, yob, yaw).
3. Kev sib cais ntawm kev vibration thiab smoothness ntawm kev txav
Mechanical bearings (pob los yog rollers) tsim "recirculation suab" uas cuam tshuam nrog kev ntsuas rhiab. Cua bearings ua hauj lwm ntawm ib tug nyias zaj duab xis ntawm cov cua pressurized, muab ib tug natural vibration dampening nyhuv. Qhov no ua rau ultra- kev txav mus los yooj yim nrog lub nrawm nrawm nrawm, uas yog qhov tseem ceeb rau siab - kev daws teeb meem duab thiab nanometer- nplai deg profileing.
4. Vim li cas Granite thiab Ceramics yog Qhov Tseem Ceeb Cua Bearing Substrates?
Kev ua tau zoo ntawm cov kabmob huab cua yog nyob ntawm qhov zoo ntawm qhov chaw nws ntab. Jinan Black Granite thiab Technical Ceramics muab cov huab cua flatness thiab thermal stability yuav tsum tau ua kom muaj qhov sib txawv ntawm 5 μm. Ib qho thermal warping ntawm substrate yuav tsoo cov kabmob, ua cov khoom xaiv qhov tseem ceeb tshaj plaws kev txiav txim siab engineering.
5. Kev sib xyaw ua ke: Kev sib xyaw ua ke ntawm Air Bearings nrog Linear Motors
Yuav kom ua tiav siab -ntaus nanoscale positioning, peb integrate Ironless Linear Motors nrog cua bearing theem. Qhov kev sib xyaw ua ke no tshem tawm "cogging" thiab kev sib nqus sib nqus, muab cov lus tsa suab huv tshaj plaws. Ntawm UNPARALLELED, peb muab tag nrho cov khoom siv sib dhos, suav nrog lub hauv paus granite, huab cua bearing pucks, thiab lub cev muaj zog mounting interfaces.

FAQ: Cua Bearing Technology
Q1: Yuav ua li cas yog tias huab cua tsis ua haujlwm?
A: Peb siv qhov chaw tsaws thaum muaj xwm txheej ceev lossis "nyuaj-coated" ceramic interfaces los tiv thaiv kev puas tsuaj. Peb kuj pom zoo kom lub siab sensors uas ua rau muaj kev kub ntxhov ceev thiab koom nrog cov neeg kho tshuab nres yog tias huab cua siab poob qis dua qhov tseem ceeb.
Q2: Cov huab cua zoo li cas rau cov kabmob no?
A: Cov huab cua yuav tsum tau lim, qhuav, thiab roj -dawb. Peb feem ntau hais txog ISO 8573-1 Chav Kawm 1.4.1 huab cua zoo kom ntseeg tau tias tsis muaj cov khoom lossis cov dej noo cuam tshuam cov sub-micron orifices ntawm huab cua bearing pucks.
Q3: Cov kabmob puas tuaj yeem ua haujlwm hauv lub tshuab nqus tsev?
A: Yog lawm, tab sis lawv xav tau lub tshuab nqus tsev- cov qauv tsim ua ntej lossis tshwj xeeb sib txawv ntawm cov ntsaws ruaj ruaj los tiv thaiv huab cua los ntawm lub tshuab nqus tsev. Cov no muaj nyob rau hauv advanced EUV semiconductor cov cuab yeej.
Q4: Yuav ua li cas cov huab cua bearings tuav hnyav loads?
A: Los ntawm kev nce thaj tsam ntawm cov kabmob pucks thiab huab cua siab (feem ntau 0.5-0.6 MPa), peb tuaj yeem txhawb nqa cov khoom xws li ob peb grams mus rau ob peb tons nrog kev sib txhuam tsis sib xws.
Q5: Puas yog nws nyuaj rau nruab huab cua bearing theem?
A: Lawv xav tau kev sib raug zoo thiab ib qho chaw tiaj tus heev. Qhov no yog vim li cas UNPARALLELED feem ntau muab cov cua bearings ua ntej-mounted thiab sim ntawm peb precision granite bases kom ntseeg tau tias "tawm- ntawm--box" kev ua tau zoo.
Q6: Dab tsi yog qhov txiaj ntsig tseem ceeb rau CMM cov tuam txhab?
A: Ceev thiab raug. Huab cua bearings tso cai rau CMM sojntsuam txav nrawm dua yam tsis muaj kev vibrations, ua rau kev soj ntsuam sai dua thiab siab dua rau cov duab geometries nyuaj pom hauv cov tshuab aerospace niaj hnub.
