Granite CMM Platform: Technical Specification & Application Guide for Metrology Professionals

Raws li cov cuab yeej metrological hauv kev tsim khoom, Granite CMM Platform (tseem hu ua marble tswj ntsuas tshuab lub rooj, precision granite ntsuas lub rooj) yog dav lees paub rau nws qhov kev ruaj ntseg zoo dua thiab raug. Lus Cim: Nws yog qee zaus misclassified nrog cam khwb cia hlau CMM platforms nyob rau hauv kev ua lag luam, tab sis lub ntuj ntxhia muaj pes tsawg leeg ntawm granite endows nws nrog irreplaceable zoo nyob rau hauv high-precision ntsuas scenarios - ib tug tseem ceeb sib txawv rau cov tub txawg nrhiav txhim khu kev qha metrological benchmarks.

1. Cov ntsiab lus tseem ceeb & Cov ntawv thov tseem ceeb

• Ua haujlwm raws li lub hauv paus ua haujlwm rau kev sib koom tes ntsuas tshuab (CMM) kev ua haujlwm, ua kom muaj tseeb qhov ntsuas qhov ntsuas ntawm cov khoom siv tshuab.
• Txhawb kev ntsuas qhov tseeb ntawm cov cuab yeej siv tshuab, txheeb xyuas qhov tseeb geometric (piv txwv li, flatness, parallelism) ntawm cov cuab yeej siv tshuab ua haujlwm.
• Ua qhov tseeb qhov tseeb thiab daim ntawv sib txawv ntawm qhov kev txiav txim siab siab (piv txwv li, aerospace Cheebtsam, automotive precision qhov chaw).
• Featuring peb tus qauv siv cov cim rau ntawm nws qhov chaw ua haujlwm, ua kom yooj yim calibration thiab muab tso rau ntawm CMM sojntsuam rau kev ntsuas kev ua haujlwm tau zoo.

2. Mineral Composition & Natural Performance Advantages

2.1 Ntsiab Mineral Composition

• Pyroxene (35-45%): Txhim kho cov qauv ntom ntom thiab hnav tsis kam.
• Plagioclase feldspar (25-35%): Ua kom zoo nkauj zoo nkauj thiab qis thermal expansion.
• Cov ntxhia pob zeb (olivine, biotite, magnetite): Pab txhawb rau cov khoom siv dub luster thiab sib nqus.
  Tom qab ntau pua lab xyoo ntawm kev laus ntawm ntuj tsim, qhov kev ntxhov siab sab hauv ntawm granite tau tso tawm tag nrho, ua rau muaj cov qauv crystalline ruaj khov uas tshem tawm cov deformation tom qab ua tiav - qhov tshwj xeeb zoo dua li cov khoom siv los ntawm tib neeg.

2.2 Technical Advantages

• Exceptional Stability: Zero internal stress los ntawm natural aging kom tsis muaj seem deformation nyob rau hauv lub sij hawm ntev los yog hnyav loads (txog 500kg / m² rau cov qauv qauv).
• High Hardness & Wear Resistance: Mohs hardness ntawm 6-7 (ntau tshaj cam khwb cia hlau lub 4-5), kom ntseeg tau qhov tsawg kawg nkaus hnav txawm tias tom qab 10,000+ ntsuas cycles.
• Corrosion & Sib Nqus Resistance: impervious rau acids, alkalis, thiab muaj kuab tshuaj; non-magnetic zog tsis txhob cuam tshuam nrog precision magnetic ntsuas cov cuab yeej.
• Tsawg Thermal Expansion: Linear expansion coefficient ntawm 5.5 × 10⁻⁶ / ℃ (1/3 ntawm cam khwb cia hlau), txo qhov sib txawv ntawm qhov sib txawv los ntawm qhov kub thiab txias.
• Kev tu qis: du, ntom ntom ntom (Ra ≤ 0.4μm) yuav tsum tsis muaj xeb-pov thawj lossis tsis tu ncua lubrication; yooj yim so nrog ib daim ntaub uas tsis muaj lint yuav ua kom huv.

3. Precision Standards & Tolerance Specifications

• Chav Kawm 000 (Ultra-Precision): Tolerance = 1 × (1 + D / 1000) μm (tsim rau ultra-high-precision CMMs hauv cov chaw kuaj mob).
• Chav Kawm 00 (High Precision): Tolerance = 2 × (1 + D / 1000) μm (zoo tagnrho rau qib CMMs hauv tsheb / aerospace manufacturing).
• Chav Kawm 0 (Precision): Kev kam rau siab = 4 × (1 + D / 1000) μm (siv rau kev ntsuas cov cuab yeej siv dav dav thiab kev tshuaj xyuas ib feem).
• Chav Kawm 1 (Standard): Tolerance = 8 × (1 + D / 1000) μm (muaj feem xyuam rau kev tswj kev ua haujlwm tsis zoo).

4. Ua hauj lwm nto yuav tsum tau & txwv

4.1 Cov Txheej Txheem Zoo rau Kev Ua Haujlwm Ntog

• Cov xuab zeb qhov, shrinkage kab noj hniav, kab nrib pleb, los yog inclusions (uas ua rau tsis sib npaug zog faib).
• Kos, abrasions, los yog xeb stains (uas distort ntsuas cov ntsiab lus siv).
• Porosity los yog tsis sib xws kev ntxhib los mos (uas ua rau hnav tsis sib xws).
  Qhov chaw tsis ua hauj lwm (xws li, sab ntug) tso cai rau kev kho me me ntawm cov dents lossis chamfer defects, yog tias lawv tsis cuam tshuam rau kev ncaj ncees.

4.2 Technical Limitations & Mitigation

• Impact Sensitivity: Tsis tuaj yeem tiv taus qhov hnyav (piv txwv li, xaum hlau qhov chaw); kev cuam tshuam yuav ua rau micro-pits (tab sis tsis yog burrs, uas tsis txhob cuam tshuam qhov ntsuas qhov tseeb).
• Humidity Sensitivity: Dej nqus dej yog ~ 1%; Lub sijhawm ntev ntawm cov av noo (> 60%) tuaj yeem ua rau muaj kev hloov pauv me ntsis. Kev txo qis: Siv cov txheej txheem tshwj xeeb silicone-raws li cov dej tsis muaj dej (muab pub dawb nrog UNPARALLELED xaj).

5. Vim li cas thiaj xaiv UNPARALLELED Granite CMM Platforms?

• Cov khoom siv: Peb tsuas yog siv "Jinan Black" granite (qib hwm nrog <0.1% impurity cov ntsiab lus), ua kom muaj kev ntxhib los mos thiab kev ua haujlwm ruaj khov.
• Precision Machining: Ua ke CNC sib tsoo (qhov siab ± 0.5μm) thiab tes-polishing (Ra ≤ 0.2μm) cov txheej txheem dhau ntawm cov qauv kev lag luam.
• Customization: Peb muab qhov tsis zoo raws li qhov ntau thiab tsawg (los ntawm 300 × 300mm txog 3000 × 2000mm) thiab tsim tshwj xeeb (xws li, T-qhov grooves, threaded qhov) kom phim koj tus qauv CMM.
• Kev Pabcuam Tomqab Muag Khoom: 2-xyoo lav, pub dawb txhua xyoo kev rov kho dua tshiab, thiab kev saib xyuas thoob ntiaj teb ntawm qhov chaw (nrog rau Tebchaws Europe, North America, thiab Southeast Asia).
