Ipulatifomu ye-Granite CMM: Ukucaciswa Kobuchwepheshe kanye Nomhlahlandlela Wokusebenza Kwabachwepheshe Be-Metrology

Njengethuluzi eliyinhloko le-metrological ekukhiqizeni ngokunemba, i-Granite CMM Platform (eyaziwa nangokuthi ithebula lomshini wokulinganisa i-marble coordinate, ithebula lokulinganisa i-precision granite) yaziwa kabanzi ngokuqina kwayo okuphezulu nokunemba. Qaphela: Ngezinye izikhathi ihlukaniswa kabi ngamapulatifomu e-CMM ensimbi ensimbi emakethe, kodwa ukwakheka kwamaminerali ngokwemvelo kwe-granite kuyinika izinzuzo ezingenakuphindwa ezimweni zokulinganisa ngokunemba okuphezulu— umehluko obalulekile kochwepheshe abafuna izilinganiso ze-metrological ezinokwethenjelwa.

1. Incazelo Eyinhloko kanye Nezicelo Eziyinhloko

• Isebenza njengebhentshi eliyisisekelo lokusebenza komshini wokulinganisa odidiyelwe (i-CMM), okuvumela ukuhlolwa okunembile kobukhulu bezingxenye zemishini.
• Ukusekela ukuhlolwa kokunemba kwamathuluzi omshini, ukuqinisekisa ukunemba kwejometri (isb., ukuthamba, ukuhambisana) kwamatafula okusebenza amathuluzi omshini.
• Ukwenza ukunemba kobukhulu kanye nokuhlolwa kokuphambuka kwamafomu kwezingxenye ezinembe kakhulu (isb., izingxenye zezindiza, izingxenye ezinembe kakhulu zezimoto).
• Iqukethe izimpawu ezintathu zokubhekisela ezijwayelekile endaweni yayo yokusebenza, okwenza kube lula ukulinganisa okusheshayo nokubeka ama-probe e-CMM ukuze kube nokusebenza kahle kokulinganisa.

2. Ukwakheka Kwamaminerali kanye Nezinzuzo Zokusebenza Kwemvelo

2.1 Ukwakheka Okuyinhloko Kwamaminerali

• I-Pyroxene (35-45%): Ithuthukisa ukuqina kwesakhiwo kanye nokumelana nokuguguleka.
• I-Plagioclase feldspar (25-35%): Iqinisekisa ukuthungwa okufanayo kanye nokukhula okuphansi kokushisa.
• Amaminerali alandelelanayo (i-olivine, i-biotite, i-magnetite): Anegalelo ekukhanyeni okumnyama kwento kanye nokumelana nomagnetic.
  Ngemva kwamakhulu ezigidi zeminyaka yokuguga ngokwemvelo, ukucindezeleka kwangaphakathi kwe-granite kukhululwa ngokugcwele, okuholela esakhiweni esiqinile sekristalu esiqeda ukuguquka ngemva kokucubungula—inzuzo eyingqayizivele ngaphezu kwezinto ezenziwe umuntu.

2.2 Izinzuzo Zobuchwepheshe

• Ukuzinza Okumangalisayo: Akukho ukucindezeleka kwangaphakathi okuvela ekugugeni kwemvelo kuqinisekisa ukuthi akukho ukuguquguquka okubonakalayo ngaphansi kwemithwalo yesikhathi eside noma esindayo (kufika ku-500kg/m² kumamodeli ajwayelekile).
• Ukuqina Okuphezulu Nokumelana Nokugqokwa: Ukuqina kwe-Mohs okungu-6-7 (kudlule insimbi engu-4-5), okuqinisekisa ukugqokwa okuncane kakhulu kwendawo ngisho nangemva kwemijikelezo yokulinganisa engaphezu kuka-10,000.
• Ukugqwala Nokumelana Nomagnetic: Ayithinteki kuma-acid, ama-alkali, kanye nezinyibilikisi zezimboni; izakhiwo ezingezona ezimagnetic zigwema ukuphazamiseka kwamathuluzi okulinganisa amagnetic anembile.
• Ukwanda Okuphansi Kokushisa: I-coefficient yokwanda okuqondile engu-5.5×10⁻⁶/℃ (1/3 yensimbi ephonswe ngensimbi), kunciphisa ukuphambuka kobukhulu okubangelwa ukushintshashintsha kwezinga lokushisa elizungezile.
• Ukugcinwa Okuphansi: Ubuso obubushelelezi, obuqinile (Ra ≤ 0.4μm) abudingi ukuvikela ukugqwala noma ukugcotshwa okuvamile; ukusula okulula ngendwangu engenama-lint kugcina ukuhlanzeka.

3. Izindinganiso Zokunemba kanye Nemininingwane Yokubekezelelana

• Isigaba 000 (Ukunemba Okuphezulu): Ukubekezelelana = 1×(1 + D/1000) μm (kufanele ama-CMM anembile kakhulu ezindaweni zelebhu).
• Isigaba 00 (Ukunemba Okuphezulu): Ukubekezelelana = 2×(1 + D/1000) μm (kufanelekile kuma-CMM asezingeni lezimboni ekukhiqizweni kwezimoto/izindiza).
• Isigaba 0 (Ukunemba): Ukubekezelelana = 4×(1 + D/1000) μm (kusetshenziselwa ukuhlolwa kwamathuluzi omshini ojwayelekile kanye nokuhlolwa kwezingxenye).
• Isigaba 1 (Esijwayelekile): Ukubekezelelana = 8×(1 + D/1000) μm (kusebenza ekulawulweni kwekhwalithi yomshini onzima).

4. Izidingo Zokusebenza Nokulinganiselwa

4.1 Izindlela Zokusebenza Ezisezingeni Eliphezulu

• Izimbobo zesihlabathi, imigodi yokuncibilika, imifantu, noma izinto ezifakiwe (ezibangela ukusatshalaliswa kwamandla okungalingani).
• Ukuklwebheka, ukuklwebheka, noma amabala okugqwala (okuphazamisa amaphuzu okubhekisela ekulinganisweni).
• Ukugoba noma ukuthungwa okungalingani (okuholela ekugugeni okungalingani).
  Izindawo ezingasebenzi (isb., imiphetho eseceleni) zivumela ukulungiswa kochwepheshe kwezimbobo ezincane noma amaphutha e-chamfer, uma nje zingathinti ubuqotho besakhiwo.

4.2 Ukulinganiselwa Kobuchwepheshe Nokunciphisa

• Ukuzwela Komthelela: Ayikwazi ukumelana nokushayisana okukhulu (isb., izingxenye zensimbi eziwayo); ukushayisana kungabangela ama-micro-pits (nakuba kungabi ama-burrs, okugwema ukuthinta ukunemba kokulinganisa).
• Ukuzwela Komswakama: Izinga lokumuncwa kwamanzi lingu-1%; ukuchayeka isikhathi eside emswakama ophezulu (>60%) kungabangela izinguquko ezincane zobukhulu. Ukunciphisa: Faka isembozo esingangeni manzi esisekelwe ku-silicone (esinikezwe mahhala ngama-oda ANGAFANELEKILE).

5. Kungani Ukhetha Amapulatifomu e-CMM e-Granite Angenakuqhathaniswa?

• Ukuthola Izinto: Sisebenzisa kuphela i-granite ethi “Jinan Black” (izinga eliphezulu kakhulu elinokuqukethwe okungcolile okungaphansi kuka-0.1%), siqinisekisa ukuthungwa okufanayo nokusebenza okuzinzile.
• Umshini Wokuchwephesha Oqondile: Izinqubo ezihlanganisiwe zokugaya i-CNC (ukubekezelelana ±0.5μm) kanye nokupholisha ngesandla (Ra ≤ 0.2μm) zidlula amazinga embonini.
• Ukwenza ngokwezifiso: Sinikeza osayizi abangajwayelekile (kusukela ku-300×300mm kuya ku-3000×2000mm) kanye nemiklamo ekhethekile (isb., imigoqo ye-T-slot, imigodi enezintambo) ukuze ifane nemodeli yakho ye-CMM.
• Ukusekelwa Ngemva Kokuthengisa: iwaranti yeminyaka emi-2, ukulinganiswa kabusha kokunembile kwaminyaka yonke kwamahhala, kanye nokugcinwa komhlaba wonke esizeni (okumboza iYurophu, iNyakatho Melika, kanye neNingizimu-mpumalanga ye-Asia).
