Ranking tus nqi ntawm Precision—Granite vs. Cast Iron vs. Ceramic Platforms

Cov Khoom Siv Tus Nqi Sib Tw hauv Ultra-Precision Manufacturing

Thaum nrhiav ib lub hauv paus rau cov cuab yeej ntsuas ntsuas tseem ceeb, kev xaiv cov khoom siv - Granite, Cam khwb cia hlau, lossis Precision Ceramic - suav nrog kev ntsuas kev nqis peev ua ntej tiv thaiv kev ua haujlwm ntev thiab ruaj khov. Thaum cov kws ua haujlwm saib xyuas qhov tseem ceeb ntawm kev ruaj ntseg thiab cov khoom cua sov, pawg neeg yuav khoom tsom rau tus nqi ntawm Cov Khoom Siv (BOM).

Ntawm ZHHIMG®, peb nkag siab tias kev txheeb xyuas cov khoom tiav yuav tsum tsis yog tsuas yog tus nqi raw tab sis kuj yog qhov nyuaj ntawm kev tsim khoom, xav tau kev ruaj ntseg, thiab kev saib xyuas mus sij hawm ntev. Raws li qhov nruab nrab ntawm kev lag luam thiab kev tsim khoom tsis yooj yim rau qhov zoo sib xws, siab-precision, metrology-qib platforms, peb tuaj yeem tsim kom muaj tus nqi tseeb.

Tus nqi Hierarchy ntawm Precision Platforms

Rau cov platforms uas tsim los rau cov qauv ntsuas ntsuas siab (piv txwv li, DIN 876 Qib 00 lossis ASME AA), tus nqi qis tshaj, los ntawm qis tshaj mus rau tus nqi siab tshaj, yog:

1. Cast Iron Platforms (Tus nqi qis tshaj plaws)

Cast Iron muab cov khoom siv qis tshaj plaws thiab cov nqi tsim khoom rau lub hauv paus qauv. Nws lub zog tseem ceeb yog nws cov rigidity siab thiab yooj yim ntawm kev sib koom ua ke ntawm cov yam ntxwv nyuaj (ribs, sab hauv voids) thaum lub sij hawm casting txheej txheem.

• Tus Nqi Tsav Tsheb: Cov khoom siv pheej yig pheej yig (hlau ore, steel seem) thiab cov txheej txheem tsim khoom ntau xyoo.
• Kev lag luam tawm: Cam khwb cia hlau qhov tsis muaj zog hauv ultra-precision yog nws qhov ua rau xeb / xeb thiab nws qhov yuav tsum tau ua rau thermal stabilization (kev kho cua sov) los txo cov kev ntxhov siab sab hauv, uas ntxiv cov nqi. Tsis tas li ntawd, nws qhov siab dua Coefficient ntawm Thermal Expansion (CTE) ua rau nws tsis haum dua li granite rau qhov muaj tseeb qhov chaw nrog qhov kub thiab txias.

2. Precision Granite Platforms (Tus Thawj Coj Tus Nqi)

Precision Granite, tshwj xeeb tshaj yog cov khoom siv ntom ntom zoo li peb 3100 kg / m3 ZHHIMG® Dub Granite, feem ntau zaum hauv nruab nrab ntawm tus nqi ntau, muab qhov zoo tshaj plaws ntawm kev ua tau zoo thiab kev them taus.

• Tus Nqi Tsav Tsheb: Thaum lub quarrying raw thiab cov khoom xaiv raug tswj, tus nqi tseem ceeb nyob rau hauv qeeb, nruj, ntau theem txheej txheem-xws li ntxhib shaping, ntev ntuj laus rau kev ntxhov siab, thiab xav tau, heev txawj kawg phau ntawv lapping kom tiav nanometer flatness.
• Tus nqi Proposition: Granite yog ib txwm tsis-sib nqus, corrosion-resistant, thiab muaj ib tug tsawg CTE thiab superior vibration damping. Tus nqi yog qhov tsim nyog vim tias granite xa cov ntawv pov thawj, kev ruaj ntseg ntev yam tsis tas yuav tsum muaj kev kho cua sov kim lossis cov txheej txheem tiv thaiv corrosion. Qhov no ua rau granite yog qhov kev xaiv zoo rau feem ntau ntawm cov niaj hnub metrology thiab semiconductor daim ntaub ntawv.

3. Precision Ceramic Platforms (Tus nqi siab tshaj)

Precision Ceramic (feem ntau high-purity Aluminium Oxide los yog Silicon Carbide) feem ntau hais kom tus nqi siab tshaj plaws hauv khw. Qhov no qhia txog cov khoom siv raw khoom synthesis thiab cov txheej txheem tsim hluav taws xob siab.

• Tus Nqi Tsav Tsheb: Cov khoom sib txuas yuav tsum muaj kev purity siab thiab kub sintering, thiab cov txheej txheem tiav (pob zeb diamond sib tsoo) nyuaj thiab kim.
• Lub Niche: Ceramics yog siv thaum huab cua nruj-rau-qhov hnyav piv thiab qhov qis tshaj qhov ua tau CTE yuav tsum tau, xws li nyob rau hauv high-acceleration linear motor theem lossis lub tshuab nqus tsev ib puag ncig. Thaum zoo dua hauv qee qhov kev ntsuas kev ntsuas, tus nqi siab heev txwv nws txoj kev siv rau kev tshwj xeeb, cov ntawv thov tshwj xeeb uas cov peev nyiaj yog qhov thib ob rau kev ua haujlwm.

Xaus: Ua ntej tus nqi tshaj tus nqi qis

Xaiv lub platform precision yog qhov kev txiav txim siab ntawm engineering tus nqi, tsis yog tus nqi pib xwb.

Thaum Cast Iron muaj qhov pib nkag qis tshaj plaws, nws cuam tshuam cov nqi zais hauv kev sib tw thermal stability thiab kev saib xyuas. Precision Ceramic muaj kev ua haujlwm siab tshaj plaws tab sis xav tau kev cog lus loj heev.

Precision Granite tseem yog tus nqi sib tw. Nws muab kev ruaj ntseg zoo, zoo tshaj thermal zog rau cam khwb cia hlau, thiab txij nkawm-dawb lub neej ntev, tag nrho ntawm tus nqi qis dua ntawm ceramic. ZHHIMG® txoj kev cog lus rau cov ntawv pov thawj zoo, txhawb nqa los ntawm peb Quad-Certifications thiab traceable metrology, xyuas kom meej tias koj cov peev hauv granite platform yog qhov kev txiav txim siab zoo tshaj plaws rau kev lees paub ultra-precision.
