Sida aaladda mitirka aasaasiga ah ee wax soo saarka saxda ah, Granite CMM Platform (sidoo kale loo yaqaan miiska mashiinka cabbiraadda isku-dubarid marmar, miiska cabbirka granite saxda ah) ayaa si weyn loogu aqoonsaday xasilloonidiisa iyo saxnaantiisa sare. Fiiro gaar ah: Mararka qaarkood waxaa lagu sifeeyaa qalabyada CMM ee birta ah ee suuqa, laakiin ka kooban macdanta dabiiciga ah ee granite waxay ku siinaysaa faa'iidooyin aan la bedeli karin oo ku jira xaaladaha cabbirka saxda ah ee saxda ah - farqiga muhiimka ah ee xirfadlayaasha raadinaya jaangooyooyin mitir oo la isku halayn karo.
1. Qeexida Muhiimka ah & Codsiyada Aasaasiga ah
Qalabka granite ee CMM waa qalab cabbiraadda saxda ah oo laga sameeyay granite dabiici ah oo heer sare ah, oo lagu farsameeyay farsamaynta CNC iyo geeddi-socod-dhammaystirka gacanta. Codsiyada aasaasiga ah waxaa ka mid ah:
- U adeegaya sidii kursiga aasaasiga ah ee shaqada isku xirka mashiinka cabbiraadda (CMM), awood u siinaya kormeer cabbir sax ah ee qaybaha farsamada.
- Taageerida tijaabinta saxda ah ee qalabka mishiinada, xaqiijinta saxnaanta joomatari (tusaale, flatness, parallelism) ee miisaska qalabka mishiinada.
- Samaynta saxnaanta cabbirka iyo qaabka qiimaynta weecasho ee qaybaha saxda ah (tusaale, qaybaha hawada sare, qaybaha saxda ah ee baabuurta).
- Muujinaya saddex calaamado tixraaceed oo heersare ah oo ku yaal dusha sare ee shaqada, fududaynta hagaajinta degdega ah iyo meelaynta tijaabooyinka CMM si loo cabbiro socodka shaqo ee hufan.
2. Halabuurka Macdanta & Faa'iidooyinka Waxqabadka Dabiiciga ah
2.1 Halabuurka Macdanta Muhiimka ah
Goobaha granite ee tayada sare leh waxay ugu horrayn ka kooban yihiin:
- Pyroxene (35-45%): Waxay xoojisaa cufnaanta qaabdhismeedka waxayna xidhataa caabbinta.
- Plagioclase feldspar (25-35%): Waxay xaqiijisaa labbiska isku midka ah iyo ballaarinta kulaylka hooseeya.
- Macdanta raadraaca (olivine, biotite, magnetite): Ka qayb qaado dhalaalka madaw ee walxaha iyo iska caabbinta magnetic.
Ka dib boqollaal milyan oo sano oo gabowga dabiiciga ah, diiqada gudaha ee granite si buuxda ayaa loo sii daayaa, taasoo keentay qaab dhismeed crystalline ah oo xasilan oo meesha ka saaraya qallafsanaanta ka dib - faa'iido gaar ah oo ka badan alaabta dadku sameeyo.
2.2 Faa'iidooyinka Farsamada
Marka la barbar dhigo tuurista birta ama aaladaha walxaha isku dhafan, aaladaha granite CMM waxay bixiyaan waxqabad aan la mid ahayn:
- Xasilooni Gaar ah: Dhibka gudaha ee ka imanaya gabowga dabiiciga ahi waxa uu xaqiijiyaa in aanu isbedel xaga cabbirka ahi ku iman culaysyada muddada dheer ama culus (ilaa 500kg/m² ee moodooyinka caadiga ah).
- Adag Adag oo Sare & Xiro Caabbi: Adkaynta Mohs ee 6-7 (ka badan kabka birta 4-5), hubinta xidhashada ugu yar ee dusha sare xitaa ka dib 10,000+ wareegyada cabbirka.
- Daxalka & Iska caabinta Magnetic: Asiidh, alkalis, iyo dareerayaasha warshadaha; Guryaha aan magnetic-ka ahayn waxay iska ilaaliyaan faragelinta qalabka cabbirka magnetic saxda ah.
- Balaadhinta kulaylka Hoose: Isku xidhka fidinta tooska ah ee 5.5×10⁻⁶/℃ (1/3 ee birta shubka ah), yaraynta weecsanaanta cabbirka ee ay keento isbedbedelka heerkulka jawiga.
- Dayactirka hooseeya: siman, oogada cufan (Ra ≤ 0.4μm) uma baahna caddayn miridhku ama saliidayn joogto ah; ku masaxidda fudud ee maro aan dheeha lahayn waxay ilaalisaa nadaafadda.
3. Heerarka Saxda ah & Tilmaamaha Dulqaadashada
Dulqaadka dabacsanaanta ee aaladaha granite CMM waxay si adag ugu hoggaansamaan heerka GB/T 4987-2019 (oo u dhiganta ISO 8512-1) waxaana loo kala saaraa afar darajo oo sax ah. Qaaciddada dulqaadka fidsanaanta waa sida soo socota (D = dhererka xajmiga ee dusha shaqada, mm; heerkulka cabbirka: 21± 2℃):
- Fasalka 000 (Ultra-Precision): Dulqaad = 1 × (1 + D/1000) μm (ku habboon CMM-yada saxda ah ee aadka u sarreeya ee deegaanka shaybaadhka).
- Fasalka 00 (Saaxsanaanta Sare): Dulqaad = 2 × (1 + D/1000) μm (ku habboon heerka-warshadeynta CMM-yada wax-soo-saarka baabuurta/aerospace).
- Fasalka 0 (Sax): Dulqaad = 4 × (1 + D/1000) μm (oo loo isticmaalo baaritaanka guud ee qalabka mashiinka iyo kormeerka qayb).
- Fasalka 1 (Standard): Dulqaad = 8 × (1 + D/1000) μm (loo adeegsan karo xakamaynta tayada mashiinnada qallafsan).
Dhammaan aaladaha granite ee aan la is barbardhigin ayaa la mariyaa xaqiijinta mitirka ee dhinac saddexaad, oo leh warbixin sax ah oo la raadin karo oo la siiyay unug kasta- hubinta u hoggaansanaanta shuruudaha tayada caalamiga ah.
4. Shuruudaha Dusha sare ee Shaqeynta & Xaddidaadaha
4.1 Shuruudaha tayada ee dusha sare ee shaqada
Si loo dammaanad qaado saxnaanta cabbiraadda, dusha sare ee shaqada ee meeraha granite CMM waa inay ka xoroobaan cilladaha saameeya waxqabadka, oo ay ku jiraan:
- Godad cammuud ah, godadka yaraaday, dildilaaca, ama ku darida (taasoo sababta qaybinta xoog aan sinnayn).
- Xaaqid, nabar, ama wasakhda miridhku (kuwaas oo qalloociya dhibcaha tixraaca).
- Porosity ama qaab-dhismeed aan sinnayn (taas oo horseedaysa xidhmo aan is-waafaqayn).
Dusha sare ee aan shaqaynayn (tusaale, geesaha dhinac) waxay u oggolaanayaan dayactir xirfadeed ee ilko yaryar ama cilladaha chamfer, waase haddii ayan saameyn ku yeelan sharafta qaabdhismeedka.
4.2 Xadaynta Farsamada & Yaraynta
In kasta oo aaladaha granite ay si sax ah ugu sarreeyaan, waxay leeyihiin xaddidaadyo gaar ah oo ay tahay in xirfadlayaashu ogaadaan:
- Dareenka Saamaynta: Uma adkeysan karo saamaynta culus (tusaale, qaybo birta ah oo soo dhacaya); Saamayntu waxay keeni kartaa godad-yar (inkasta oo aanay ahayn dabaysha, taas oo ka fogaanaysa inay saamayso saxnaanta cabbirka).
- Dareenka Humidity: Heerka nuugista biyaha waa ~ 1%; Soo-gaadhista muddada dheer ee huurka sare (> 60%) waxay keeni kartaa isbeddelo cabbir yar. Yaraynta: Codso daahan gaar ah oo silikoon ku salaysan oo aan biyuhu lahayn (waxaa lagu bixiyaa amaro AAN LA FAAHFAAHIN).
5. Waa maxay sababta aad u dooratay Platforms Granite CMM AAN LA ISBARBARAYN?
- Isha Walxaha: Waxaan si gaar ah u isticmaalnaa "Jinan Black" granite (daraajo qaali ah oo leh <0.1% wax aan nadiif ahayn), hubinta qaab-dhismeedka isku midka ah iyo waxqabadka xasilloon.
- Mashiinka Saxda ah: Shiididda CNC ee isku dhafan (dulqaadka ± 0.5μm) iyo dhaqidda gacmaha (Ra ≤ 0.2μm) hababka ayaa ka sarreeya heerarka warshadaha.
- Habaynta: Waxaan bixinaa cabbirro aan caadi ahayn (laga bilaabo 300 × 300mm ilaa 3000 × 2000mm) iyo naqshado gaar ah (tusaale, T-slot grooves, godadka dunta) si ay u dhigmaan qaabkaaga CMM.
- Taageerada Iibka Kadib: 2-sano oo dammaanad ah, dib-u-habayn sax ah oo sanadle ah oo bilaash ah, iyo dayactirka goobta caalamiga ah (oo daboolaya Yurub, Waqooyiga Ameerika, iyo Koonfur-bari Aasiya).
