Kwihlabathi lobunjineli bokuchaneka, i-metrology, kunye nokuveliswa kwezinto eziphezulu, ukuchaneka akuyonjongo nje kuphela—yinto efunekayo ngokupheleleyo. Eyona nto iphambili kokuchaneka kukwisixhobo esisisiseko: ipleyiti yomphezulu. Nangona iipleyiti zesinyithi kunye nentsimbi bezidlala indima kwiiworkshops, i-granite iye yavela njengezinto ezikhethwayo kwiindawo zanamhlanje nezichaneke kakhulu. Nangona kunjalo, ayizizo zonke iipleyiti zomphezulu we-granite ezenziwe ngokulinganayo. Ukuqinisekisa ukuthembeka kokulinganisa kwakho, kubalulekile ukuqonda umgangatho wamazwe ngamazwe olawulayo: i-DIN 876.
Esi sikhokelo siza kukufundisa izinto ezibalulekileyo ze-DIN 876, sikuncede uhambe kwiindidi ezahlukeneyo kwaye ukhethe ipleyiti yomphezulu wegranite efanelekileyo kwiimfuno zakho zoshishino.
Kutheni iGranite ilukhetho oluphezulu lokuchonga
Ngaphambi kokuba ungene kwimigangatho yobugcisa, kubalulekile ukuqonda ukuba kutheni i-granite iyinto ekhethwayo kwiiplati zomphezulu ezichanekileyo. Iimpawu zomzimba ze-granite zibonelela ngeenzuzo ezahlukeneyo kunezinye iindlela zesinyithi, nto leyo eyenza ukuba ifaneleke kwiindawo apho uzinzo lobushushu kunye nokuchaneka kwexesha elide kubaluleke kakhulu.
Okokuqala nokubalulekileyo, igranite iqinile ngendlela emangalisayo. Igranite esemgangathweni ophezulu esetyenziswa kwi-metrology idla ngokuba nobunzima be-Mohs obuyi-6 ukuya kwi-7, obunzima kunentsimbi eqinileyo. Oku kuqinisekisa ukuba umphezulu awugugi kwaye awugugi, ugcina ulungelelwano lwawo nakwiindawo ezixakekileyo zokusebenzela. Ngokungafaniyo nentsimbi, igranite ayinamagnethi ngokupheleleyo kwaye ayisebenzisi umbane, nto leyo ephelisa ukuphazamiseka ngexesha lokulinganisa okubonakalayo kwe-elektroniki okanye kwemagnethi.
Mhlawumbi eyona nzuzo ibalulekileyo kukuzinza kobushushu begranite. Inomlinganiselo ophantsi wokwanda kobushushu kunye nokuqhuba kobushushu okuphantsi. Oku kuthetha ukuba ukuguquguquka kobushushu obuphakathi kunempembelelo encinci kubungakanani bepleyiti, kwaye ubushushu bendawo (njengobuvela ezandleni zomsebenzi okanye into efudumeleyo ebekwe etafileni) bunyamalala kancinci nangokulinganayo, buthintela ukugqwetheka. Ngaphezu koko, igranite ngokwemvelo ayidli mhlwa kwaye imelana kakhulu nee-asidi, iqinisekisa ubomi obude kunye nokugcinwa okuncinci. Ukongeza, igranite yodidi oluphezulu iyafana ngokwesakhiwo kwaye ayinaxinzelelo lwangaphakathi, oko kuthetha ukuba iyamelana nokugoba nokujika ngokuhamba kwexesha.
Ukucacisa i-DIN 876 Standard
I-DIN 876 ngumgangatho wezoshishino waseJamani ochaza iimfuno zeepleyiti zomphezulu wegranite. Iyaziwa ngokubanzi kwihlabathi liphela njengomgangatho womgangatho kwi-metrology. Lo mgangatho ulawula yonke into ukusuka kuhlobo lwelitye elisetyenzisiweyo ukuya kwimida evumelekileyo yokuba tyaba.
Umgangatho uhlela iipleyiti zomphezulu wegranite zibe ziiklasi ezine ezahlukeneyo zokuchaneka. Ukukhetha izinga elifanelekileyo kukulinganisela phakathi kwenqanaba lokuchaneka olifunayo kunye nohlahlo-lwabiwo mali olukhoyo. Ngokubanzi, izinga lokuchaneka liphezulu, kokukhona iindleko ziphezulu ngenxa yomsebenzi omninzi ofunekayo kwiinkqubo zokulepha nokukrwela.
Ibanga 00: Umgangatho weLebhu
Ibanga 00 limele incopho yokuthamba nokuchaneka. Iipleyiti zomphezulu ezihlangabezana nalo mgangatho zenziwe ngokunyamezelana okuqinileyo kwaye zenzelwe ukusetyenziswa kwiindawo ezilawulwayo, njengeelebhu zokuhlola kunye namagumbi okulinganisa. Ukuba umsebenzi wakho ubandakanya ukuqinisekisa ezinye izixhobo zokulinganisa okanye ukwenza imilinganiselo echanekileyo kakhulu apho nokuba yi-micron yempazamo ingamkelekanga, iBanga 00 lukhetho lwakho olufunekayo. Ezi pleyiti azifumaneki rhoqo kumgangatho wefektri ngenxa yomngcipheko womonakalo kunye nokungazinzi kokusingqongileyo.

Ukukhetha iBanga elifanelekileyo kwiSicelo sakho
Ukukhetha ibakala elifanelekileyo le-DIN 876 kuxhomekeke ekubuzeni imibuzo efanelekileyo malunga nendlela osebenza ngayo. Kufuneka uqwalasele indawo apho ipleyiti iza kuhlala khona kunye nemisebenzi ethile eza kuyenza.
Ukuba ufaka ilebhu yokulawula umgangatho elawulwa bubushushu apho kusayinwa khona okokugqibela kwi-aerospace okanye kwizixhobo zonyango, ukutyala imali kwipleyiti yeBanga 00 okanye yeBanga 0 akunakuxoxiswana ngayo. Ixabiso liyathethelelwa ngokuqinisekiswa kokuchaneka okupheleleyo.
Kwindawo exakekileyo apho oomatshini kufuneka bafake ii-CNC mills okanye ii-lathes, ipleyiti yeBanga loku-1 idla ngokuba yeyona ndawo ilungileyo. Ichanekile ngokwaneleyo ukuqinisekisa ukuba iindawo zenziwe ngomatshini ngokuchanekileyo kodwa zomelele ngokwaneleyo ukumelana nokungcangcazela kunye nomsebenzi womgangatho wemveliso.
Ukuba iimfuno zakho zezokwenziwa okunzima, iitafile zokuwelda, okanye ukuhlanganiswa okurhabaxa apho ukunyamezelana kulinganiswa ngeemilimitha endaweni yee-microns, ipleyiti yeBanga lesi-2 iya kukunceda kakuhle ngaphandle kokuphazamisa uhlahlo lwabiwo-mali.
Isiphelo
Ukuqonda imigangatho ye-DIN 876 linyathelo lokuqala lokuqinisekisa ukuba iinkqubo zakho zokuvelisa nezokuhlola zakhiwe kwisiseko esiqinileyo. Iipleyiti zomphezulu wegranite zibonelela ngozinzo olungenakuthelekiswa nanto, ubulukhuni, kunye nokuqina, kodwa ixabiso lazo liyabonakala ngokupheleleyo kuphela xa uthelekisa umgangatho ochanekileyo wokuchaneka nesicelo sakho esithile.
Nokuba ufuna ukugqibelela kwe-DIN 876 Grade 00 kwilebhu okanye ukuthembeka okuqinileyo kweGrade 1 kumgca wakho wemveliso, ukukhetha isixhobo esifanelekileyo kuqinisekisa ukuba imilinganiselo yakho ithembekile, iinkqubo zakho ziyasebenza, kwaye iimveliso zakho zokugqibela zihlangabezana nemigangatho ephezulu yomgangatho. Ngokutyala imali kwi-granite surface plate efanelekileyo, utyala imali ekuchanekeni nasekudumeni kwayo yonke imisebenzi yakho.
