A matsayin ainihin kayan aiki na metrological a cikin masana'anta na daidaitattun masana'antu, Granite CMM Platform (wanda kuma aka sani da teburin auna ma'aunin marmara, tebur ma'aunin ma'auni) an san shi sosai don ingantaccen kwanciyar hankali da daidaito. Lura: Wani lokaci ana yin kuskure tare da simintin ƙarfe CMM dandamali a kasuwa, amma abubuwan ma'adinai na halitta na granite yana ba shi fa'idodi maras ma'auni a cikin ma'aunin ma'aunin ma'auni mai mahimmanci - bambanci mai mahimmanci ga ƙwararrun masu neman amintattun ma'auni.
1. Core Definition & Primary Applications
Dandali na granite CMM kayan aiki ne na ma'aunin ma'aunin ma'auni wanda aka kera daga babban granite na halitta, wanda aka ƙera ta hanyar injinan CNC da ayyukan gamawa da hannu. Babban aikace-aikacen sa sun haɗa da:
- Yin hidima a matsayin tushen tushen aiki don gudanar da ayyukan injunan aunawa (CMM), yana ba da damar ingantacciyar ma'auni na kayan aikin injiniya.
- Taimakawa daidaitaccen gwajin kayan aikin injin, tabbatar da daidaiton lissafi (misali, lebur, daidaici) na kayan aikin injin.
- Gudanar da daidaiton ƙima da ƙima na ƙima na madaidaicin sassa (misali, abubuwan haɗin sararin samaniya, daidaitattun sassa na mota).
- Yana nuna madaidaitan alamomi guda uku akan saman aikin sa, yana sauƙaƙe saurin daidaitawa da kuma sanya abubuwan binciken CMM don ingantaccen ma'auni na aiki.
2. Ma'adinan Ma'adinai & Abubuwan Amfanin Halitta
2.1 Maɓalli Mai Ma'adinai
Manyan dandamali na granite sun ƙunshi da farko:
- Pyroxene (35-45%): Yana haɓaka yawan tsari da juriya.
- Plagioclase feldspar (25-35%): Yana tabbatar da nau'in nau'in nau'i da ƙananan haɓakar zafi.
- Race ma'adanai (olivine, biotite, magnetite): Ba da gudummawa ga baƙar fata da juriya na maganadisu.
Bayan daruruwan miliyoyin shekaru na tsufa na halitta, damuwa na ciki na granite ya cika cikakke, yana haifar da tsayayyen tsari na crystalline wanda ke kawar da nakasar bayan sarrafawa - fa'ida ta musamman akan kayan da mutum ya yi.
2.2 Fa'idodin Fasaha
Idan aka kwatanta da simintin ƙarfe ko dandali na kayan abu, dandali na granite CMM suna ba da aiki mara misaltuwa:
- Ƙarfafawa Na Musamman: Rashin damuwa na ciki daga tsufa na halitta yana tabbatar da cewa babu nakasar girma a ƙarƙashin dogon lokaci ko nauyi mai nauyi (har zuwa 500kg/m² don daidaitaccen ƙira).
- Babban Taurin & Saka Juriya: Taurin Mohs na 6-7 (mafi girman simintin ƙarfe na 4-5), yana tabbatar da ƙarancin lalacewa ko da bayan 10,000+ hawan keke.
- Lalata & Magnetic Resistance: Rashin ƙarfi ga acid, alkalis, da kaushi na masana'antu; kaddarorin da ba na maganadisu ba suna guje wa tsangwama tare da daidaitattun kayan aikin ma'aunin maganadisu.
- Fitar da zafin rana: Yankin fadada madaidaiciya na 5.5 × 10⁻⁶ / ℃ (1/3 na satar baƙin ƙarfe), ragewar yanayin karkatar da yanayin zafi wanda ya haifar da lalacewar zafin jiki wanda ya haifar da lalacewar zafin jiki.
- Low Maintenance: M, m surface (Ra ≤ 0.4μm) ba bukatar wani tsatsa-proofing ko na yau da kullum lubrication; shafa mai sauƙi tare da zane maras lint yana kula da tsabta.
3. Ma'auni Madaidaici & Ƙimar Haƙuri
Haƙuri da kwanciyar hankali na dandamali na CMM granite yana bin ƙa'idodin GB/T 4987-2019 (daidai da ISO 8512-1) kuma an rarraba shi cikin madaidaitan maki huɗu. The flatness dabara dabara ne kamar haka (D = diagonal tsawon na aiki surface, a mm; auna zafin jiki: 21± 2℃):
- Class 000 (Ultra-Precision): Haƙuri = 1 × (1 + D/1000) μm (wanda ya dace da madaidaicin madaidaicin CMM a cikin mahallin dakin gwaje-gwaje).
- Class 00 (High Precision): Haƙuri = 2 × (1 + D/1000) μm (mai kyau ga masana'antu-grade CMMs a cikin mota / Aerospace masana'antu).
- Class 0 (Madaidaici): Haƙuri = 4 × (1 + D / 1000) μm (an yi amfani da shi don gwajin kayan aikin injin gabaɗaya da dubawar sashi).
- Class 1 (Standard): Haƙuri = 8 × (1 + D/1000) μm (wanda ya dace da sarrafa ingantattun machining).
Duk dandamalin dutsen da ba a kwatanta su ba suna fuskantar tantancewar yanayin yanayi na ɓangare na uku, tare da ingantaccen rahoton da aka tanadar don kowace naúrar-tabbatar da bin ƙa'idodin ingancin ƙasa da ƙasa.
4. Aiki Surface Bukatun & Iyakance
4.1 Ingantaccen Ma'auni don Filayen Aiki
Don tabbatar da daidaiton aunawa, farfajiyar aiki na dandamali na CMM granite dole ne su kasance marasa lahani waɗanda ke shafar aiki, gami da:
- Ramin yashi, ramukan raguwa, fasa, ko haɗa (wanda ke haifar da rarraba ƙarfi mara daidaituwa).
- Scratches, abrasions, ko tsatsa (wanda ke gurbata ma'aunin ma'auni).
- Porosity ko rashin daidaituwa (wanda ke haifar da lalacewa mara daidaituwa).
Filayen da ba sa aiki (misali, gefuna na gefe) suna ba da izinin ƙwararrun gyare-gyare na ƙananan hakora ko lahani, muddin ba su yi tasiri ga amincin tsari ba.
4.2 Ƙayyadaddun Fasaha & Ragewa
Duk da yake dandamali na granite sun yi fice a daidaici, suna da takamaiman iyakoki waɗanda ƙwararru yakamata su lura:
- Hankalin Tasiri: Ba za a iya jure tasiri mai nauyi ba (misali, faɗuwar sassan ƙarfe); Tasirin na iya haifar da ƙananan ramuka (ko da yake ba burrs ba, wanda ke guje wa tasirin daidaiton aunawa).
- Hankalin Danshi: Yawan sha ruwa shine ~1%; Tsawaita bayyanar da zafi mai zafi (> 60%) na iya haifar da ɗan canje-canjen girma. Ragewa: Aiwatar da abin rufe fuska na musamman na silicone (wanda aka bayar kyauta tare da oda mara kyau).
5. Me yasa Zabi Platforms na Granite CMM MARASA KYAU?
- Kayan aiki na kayan: Muna amfani da "Jinan Black" Granite (babban saiti tare da <0.1% abun ciki na suturar kaya da kuma tsayayyen aikin.
- Daidaitaccen Machining: Haɗewar CNC niƙa (haƙuri ± 0.5μm) da goge-goge (Ra ≤ 0.2μm) matakai sun wuce ka'idodin masana'antu.
- Keɓancewa: Muna ba da nau'ikan da ba daidai ba (daga 300 × 300mm zuwa 3000 × 2000mm) da ƙira na musamman (misali, T-slot grooves, ramukan threaded) don dacewa da ƙirar CMM ku.
- Tallafin Bayan-tallace-tallace: Garanti na shekara 2, sake daidaita daidaitaccen daidaitaccen shekara-shekara kyauta, da kiyayewa a kan rukunin yanar gizon duniya (wanda ke rufe Turai, Arewacin Amurka, da kudu maso gabashin Asiya).
