Dab tsi yog cov hnav tsis kam ntawm precision graniteents?

Precision Granite yog ib txwm yog ib feem tseem ceeb ntawm ntau yam kev lag luam xws li kev tsim khoom, kho tsheb, thiab aerospace. Lawv tau siv rau hauv ntau cov ntawv thov vim tias lawv cov kev ruaj khov zoo tshaj plaws, kev ruaj khov, thiab cov raug. Ib qho ntawm cov tseem ceeb ntawm cov khoom siv granite yog lawv cov coj tsis kam, uas ua rau lawv zoo tagnrho rau kev siv nyob rau hauv ib puag ncig muaj ib puag ncig thiab cov ntawv thov.

Hnav tsis kam yog lub peev xwm ntawm cov khoom siv los tiv thaiv kev hnav, kev yaig lossis kev tsis sib haum xeeb vim muaj kev cuam tshuam nrog ib puag ncig ib puag ncig lossis lwm yam khoom siv. Granite muaj qhov tshwj xeeb hnav tsis kam piv rau feem ntau lwm cov ntaub ntawv. Thaum xav txog cov coj tsis kam ntawm precision graniteents, cov ntsiab lus hauv qab no yuav tsum tau txiav txim siab:

Kev nyuaj

Granite yog ib qho nyuaj thiab cov khoom siv ntom ntom, uas muab nws cov khoom tiv thaiv zoo tshaj plaws. Lub hardness ntawm granite yog ntsuas ntawm mohs nplai, uas yog qhov muaj peev xwm tiv thaiv kev hnav thiab tuaj yeem tiv thaiv tas li hauv kev puas tsuaj tas li tsis muaj kev puas tsuaj.

Nto tas

Qhov chaw ua tiav ntawm precision granite, tseem tuaj yeem ua lub luag haujlwm tseem ceeb hauv lawv cov kev coj tsis kam. Ib tug zoo-polished thiab du nto yuav pab txo kev sib txhuam thiab hnav. Qhov kev ua tiav saum npoo no tiav los ntawm precision machining machising thiab polishing txheej txheem. Qhov siab dua qib ntawm polishing, smoother rau saum npoo, thiab qhov zoo dua nws cov coj tsis kam.

Tshuaj Kuj

Granite yog cov khoom siv inert xreatically, uas txhais tau tias nws yog heev resistant rau tshuaj corrosion. Qhov no ua rau nws cov khoom siv uas tsim nyog rau cov ntawv thov uas raug tshuaj lom neeg yog kev tsis taus. Qhov tsis kam ntawm Granite rau cov kua qaub thiab alkali ua rau nws ruaj khov thiab tsis tshua hnav.

Thermal ruaj khov

Granite yog qhov ruaj khov nyob rau hauv ib puag ncig kub heev. Qhov qis coefficient ntawm thermal expansion ntawm granite ua rau nws tsis tshua muaj kev cia siab los yog tawg txawm tias thaum raug kub. Qhov no ua rau cov khoom siv granite haum rau kev siv hauv cov ntawv thov uas yuav tsum muaj qhov ntsuas siab, xws li metrology, qhov chaw tswj qhov ntsuas kub.

Hauv kev xaus, precision granite yog cov hnav zoo heev thiab tuaj yeem tiv taus cov mob hnyav. Lawv lub hardness, nto tiav, tshuaj lom neeg ua tiav, thiab thermal ruaj khov ua rau lawv zoo rau kev siv hauv cov ntawv thov uas xav tau durability thiab precision. Cov Khoom Siv Zoo Granite tuaj yeem siv sijhawm ntev xyoo, ua rau lawv daws tau nqi thiab txhim khu kev ua haujlwm zoo rau ntau yam kev lag luam.
