Qhov twg Ceramic yeej ob qho tib si Hlau thiab Pob Zeb hauv Cov Khoom Siv Precision

Granite thiab mineral casting daws tau feem ntau ntawm cov teeb meem kev ruaj khov hauv kev tsim tshuab precision, tab sis muaj ib chav kawm ntawm daim ntawv thov uas tsis muaj ib qho zoo txaus, thiab cov engineers ncav cuag rau kev siv ceramic technical - feem ntau yog alumina lossis zirconia-based cov ntaub ntawv.

Qhov laj thawj yog vim muaj qhov tawv thiab hnav tsis kam ntau dua li qhov kub thiab txias. Granite ruaj khov tab sis mos thiab tawg yooj yim thaum thauj khoom; ib qho khoom tawv uas raug ntes ntawm ib qhonto granitethiab ib qho khoom txav tau tuaj yeem khawb lossis tawg nws. Piv txwv li, cov khoom siv ceramics muaj qhov nyuaj nyob rau hauv qhov ntau ntawm 1,200-1,500 HV - zoo dua li cov hlau cuab yeej tawv - thaum khaws cov coefficient ntawm thermal expansion uas feem ntau qis dua granite. Qhov kev sib xyaw ua ke ntawm qhov nyuaj, CTE qis, thiab tshuaj lom neeg inertness yog vim li cas cov khoom siv ceramics tshwm sim tshwj xeeb hauv cov khoom ntawm lub tshuab uas muaj kev sib cuag ntau zaus lossis ib puag ncig hnyav: cov spindles cua, cov guideway rails raug rau kev sib cuag tas li, thiab cov khoom siv siv sab hauv lub tshuab nqus tsev lossis cov txheej txheem corrosive hauv semiconductor fabrication.

Qhov zoo ntawm qhov hnyav tsis muaj leej twg tham txog txaus

Cov khoom siv ceramic kuj khiav li 30-40% sib dua li hlau uas muaj qhov sib npaug, thiab sib dua li granite hauv ntau qhov geometries. Rau txhua lub kaw lus uas ib qho khoom yuav tsum tau nrawm thiab qeeb dua - ib sab caj npab wafer, ib theem optical scanning ceev - txo cov khoom txav mus los yam tsis muaj kev txi rigidity txhais tau tias ncaj qha mus rau hauv throughput siab dua thiab qis dua servo motor load. Qhov no yog ib feem ntawm vim li cas cov khoom ceramic tau dhau los ua ntau hauv cov khoom siv ceev ceev thiab hauv cov theem txav mus los ntawm AOI (automated optical inspection) systems, qhov twg lub sijhawm voj voog yog tus nqi ncaj qha.

Kev piav qhia: tus nqi thiab lub sijhawm ua haujlwm

Tsis muaj ib yam dab tsi no los pub dawb. Cov khoom siv ua los ntawm cov av nplaum uas raug ntsuas yog qhov nyuaj thiab qeeb rau kev siv tshuab - tib qho kev tawv uas ua rau nws tsis yooj yim hnav kuj ua rau nws kim heev rau kev sib tsoo kom nruj, thiab cov qauv geometries feem ntau xav tau cov cuab yeej pob zeb diamond thiab lub sijhawm voj voog ntev dua li cov hlau lossis granite sib npaug. Qhov no yog vim li cas cov av nplaum feem ntau raug tseg rau cov khoom tshwj xeeb uas xav tau nws cov khoom - cov nplaim bearing, cov phaj hnav, cov khoom chamber - es tsis txhob siv ua cov khoom siv txaj tag nrho, qhov twg granite lossis cov khoom siv casting tseem pheej yig dua rau tib qho kev sib zog-rau-tus nqi piv.
