Iqonga leGranite CMM: Inkcazelo yoBugcisa kunye neSikhokelo seSicelo seeNgcali zeMetrology

Njengesixhobo esiphambili semetrological ekwenzeni ngokuchanekileyo, iGranite CMM Platform (ekwaziwa ngokuba yitheyibhile yomatshini wokulinganisa imabula, itafile yokulinganisa igranite echanekileyo) yaziwa ngokubanzi ngokuzinza kwayo okuphezulu kunye nokuchaneka. Qaphela: Ngamanye amaxesha ihlelwa kakubi ngamaqonga e-CMM esinyithi akwimarike, kodwa ukwakheka kwezimbiwa zendalo zegranite kuyinika iingenelo ezingenakutshintshwa kwiimeko zokulinganisa ngokuchanekileyo okuphezulu— umahluko obalulekileyo kwiingcali ezifuna imilinganiselo yemetrological ethembekileyo.

1. Inkcazo ePhambili kunye nezicelo eziphambili

• Isebenza njengesiseko somsebenzi wokulinganisa oomatshini (CMM), ivumela ukuhlolwa okuchanekileyo kobukhulu bezinto zoomatshini.
• Ukuxhasa uvavanyo oluchanekileyo lwezixhobo zomatshini, ukuqinisekisa ukuchaneka kwejometri (umz., ukuthamba, ukufana) kweetafile zokusebenza zezixhobo zomatshini.
• Ukuqhuba ukuchaneka kobukhulu kunye novavanyo lokuphambuka kwesakhiwo seendawo ezichanekileyo (umz., iindawo zeenqwelo-moya, iindawo ezichanekileyo zeemoto).
• Iquka iimpawu ezintathu ezimiselweyo kumphezulu wayo wokusebenza, nto leyo enceda ekulinganisweni ngokukhawuleza nasekubekweni kwee-probes ze-CMM ukuze kubekho imisebenzi yokulinganisa esebenzayo.

2. Ulwakhiwo lwezimbiwa kunye neenzuzo zokusebenza kwendalo

2.1 Ulwakhiwo lwezimbiwa oluPhambili

• I-Pyroxene (35-45%): Yonyusa uxinano lwesakhiwo kunye nokumelana nokuguguleka.
• I-Plagioclase feldspar (25-35%): Iqinisekisa ukuthungwa okufanayo kunye nokwanda okuphantsi kobushushu.
• Iiminerali ezilandelelanayo (i-olivine, i-biotite, i-magnetite): Zinegalelo ekukhanyeni okumnyama kwezinto kunye nokumelana nemagnethi.
  Emva kwamakhulu ezigidi zeminyaka yokwaluphala kwendalo, uxinzelelo lwangaphakathi lwegranite lukhululwa ngokupheleleyo, nto leyo ephumela kwisakhiwo esiqinileyo sekristale esisusa ukuguquka emva kokulungiswa—inzuzo ekhethekileyo ngaphezu kwezinto ezenziwe ngumntu.

2.2 Iingenelo zobuGcisa

• Uzinzo Olungaqhelekanga: Akukho xinzelelo lwangaphakathi oluvela ekwaluphaleni kwendalo luqinisekisa ukuba akukho tshintsho lubonakalayo phantsi kwemithwalo yexesha elide okanye enzima (ukuya kuthi ga kwi-500kg/m² kwiimodeli eziqhelekileyo).
• Ukuqina Okuphezulu Nokumelana Nokunxiba: Ubunzima beMohs obuyi-6-7 (budlula intsimbi ephoswe kwi-4-5), okuqinisekisa ukungonakali komphezulu nokuba emva kwemijikelo yokulinganisa engaphezu kwe-10,000.
• Ukugqwala kunye nokuxhathisa iMagnetic: Ayichaphazeleki zii-asidi, ii-alkalis, kunye nezinyibilikisi zoshishino; iipropati ezingezizo zemagnethi ziphepha ukuphazamiseka kwezixhobo zokulinganisa ngokuchanekileyo imagnethi.
• Ukwandiswa kobushushu obuphantsi: I-coefficient yokwandiswa komgca we-5.5×10⁻⁶/℃ (1/3 yesinyithi esityhidiweyo), kunciphisa ukuphambuka kobukhulu okubangelwa kukuguquguquka kobushushu obuphakathi.
• Ukugcinwa Okuphantsi: Umphezulu ogudileyo noxineneyo (Ra ≤ 0.4μm) awufuni kuthintela umhlwa okanye ukuthambisa rhoqo; ukusula nje ngelaphu elingena-lint kugcina ucoceko.

3. Imigangatho echanekileyo kunye neenkcukacha zokunyamezelana

• Iklasi 000 (Uchaneko Oluphezulu): Ukunyamezelana = 1×(1 + D/1000) μm (ifanelekile kwii-CMM ezichaneke kakhulu kwiindawo zelebhu).
• Iklasi 00 (Ubuchule obuphezulu): Ukunyamezelana = 2×(1 + D/1000) μm (ilungele iiCMM zezinga lemizi-mveliso kwimveliso yeemoto/yeenqwelo-moya).
• Udidi 0 (Ukuchaneka): Ukunyamezelana = 4×(1 + D/1000) μm (kusetyenziselwa uvavanyo lwezixhobo zomatshini ngokubanzi kunye nokuhlolwa kwenxalenye).
• Udidi 1 (Umgangatho): Ukunyamezelana = 8×(1 + D/1000) μm (kusebenza kulawulo lomgangatho womatshini onzima).

4. Iimfuno kunye nemida yoMphezulu wokusebenza

4.1 Iikhrayitheriya zoMgangatho kwiindawo zokusebenzela

• Imingxunya yesanti, imingxunya yokuncipha, imifantu, okanye izinto eziqukethwe kuyo (ezibangela ukusasazwa kwamandla okungalinganiyo).
• Imikrwelo, ukukrweleka, okanye amabala okugqwala (okubangela ukuphazamiseka kweendawo zokulinganisa).
• Ukugutyungelwa okanye ukuthungwa okungalinganiyo (okukhokelela ekugugulekeni okungalinganiyo).
  Iindawo ezingasebenziyo (umz., imiphetho esecaleni) zivumela ukulungiswa kobuchwephesha kwezimbobo ezincinci okanye iziphene ze-chamfer, ukuba azichaphazeli ukuqina kwesakhiwo.

4.2 Imida yoBugcisa kunye nokuNciphisa

• Uvakalelo kwiMpembelelo: Ayikwazi ukumelana neempembelelo ezinzima (umz., ukuwisa iindawo zesinyithi); iimpembelelo zinokubangela ii-micro-pits (nangona zingeyiyo i-burrs, nto leyo ethintela ukuchaphazela ukuchaneka komlinganiselo).
• Ubushushu Bokufuma: Izinga lokufunxwa kwamanzi yi ~1%; ukuvezwa ixesha elide kumswakama ophezulu (>60%) kunokubangela utshintsho oluncinci kubukhulu. Ukunciphisa: Faka i-coating ekhethekileyo engangeni manzi esekelwe kwi-silicone (inikwe simahla ngee-odolo EZINGAFANIYO).

5. Kutheni Ukhetha iiPlatforms ze-CMM zeGranite EZINGENAKWENZEKIYO?

• Ukufunyanwa kwezinto: Sisebenzisa kuphela i-granite ethi “Jinan Black” (umgangatho ophezulu ongaphantsi kwe-0.1% yokungcola), siqinisekisa ubume obufanayo kunye nokusebenza okuzinzileyo.
• Umatshini Ochanekileyo: Iinkqubo ezidibeneyo zokugaya i-CNC (ukunyamezelana ± 0.5μm) kunye nokupolisha ngesandla (Ra ≤ 0.2μm) zidlula imigangatho yoshishino.
• Ukwenziwa ngokwezifiso: Sinikezela ngobukhulu obungaqhelekanga (ukusuka kwi-300×300mm ukuya kwi-3000×2000mm) kunye noyilo olukhethekileyo (umz., imingxunya ye-T-slot, imingxunya enemisonto) ukuze ihambelane nemodeli yakho ye-CMM.
• Inkxaso Emva Kokuthengisa: Iwaranti yeminyaka emi-2, uhlengahlengiso lwasimahla lonyaka, kunye nokugcinwa kweendawo kwihlabathi liphela (kuquka iYurophu, uMntla Melika, kunye noMzantsi-mpuma weAsia).
