Kwihlabathi lokwenziwa kombane, ngakumbi kwimveliso yeebhodi zeesekethe eziprintiweyo (PCBs), ukuqinisekiswa komgangatho kubaluleke kakhulu. Esinye sezona zixhobo zisebenzayo zokuqinisekisa ukuchaneka kunye nokuchaneka kwi-PCB yokwenziwa kukusetyenziswa kweebhodi zokuhlola igranite. Ezi ndawo zinamandla kwaye zizinzile zibonelela ngeenzuzo ezahlukeneyo eziphakamisa inkqubo yokuqinisekisa umgangatho.
Okokuqala, iipleyiti zokuhlola i-granite zibonelela ngokugqwesa okugqwesileyo kunye nokuqina. Iimpawu zendalo ze-granite zenza ukuba umphezulu ungabi caba kakhulu, kodwa ungaphantsi kwe-warping kunye nokuguqulwa kwexesha. Olu uzinzo lubalulekile xa kulinganisa ii-PCBs, njengoko nezona zitenxo zincinci zinokukhokelela kwiimpazamo ezibalulekileyo kwinkqubo yokwenziwa kwemveliso. Ngokusebenzisa iipleyiti zegranite, abavelisi banokuqinisekisa ukuba imilinganiselo yabo ichanekile, okukhokelela kwiimveliso ezikumgangatho ophezulu.
Ukongeza, iibhodi zokuhlola zegranite zomelele kakhulu kwaye ziyakwazi ukunxiba. Ngokungafaniyo nezinye izinto ezinokuthi zithobe okanye zonakaliswe ngokuhamba kwexesha, i-granite igcina ingqibelelo yayo, inika isisombululo esihlala ixesha elide sokuqinisekisa umgangatho. Oku komelela kuthetha iindleko eziphantsi zogcino kunye nokutshintshwa okuncinci rhoqo, ukwenza iibhodi zegranite zibe lukhetho olufikelelekayo kubavelisi bePCB.
Enye inzuzo ebalulekileyo yeepleyiti zokuhlola i-granite kukuhambelana kwazo kunye noluhlu olubanzi lwezixhobo zokulinganisa. Ingaba usebenzisa i-calipers, i-micrometers okanye ukulungelelanisa oomatshini bokulinganisa (i-CMMs), iipleyiti zegranite ziyakwazi ukufumana izixhobo ezahlukeneyo, ezizenza zilungele izicelo ezahlukeneyo zokuqinisekisa umgangatho. Oku kulungelelaniswa kwenza abavelisi balungelelanise iinkqubo zabo zokuhlola kunye nokuphucula ukusebenza kakuhle.
Ukuqukumbela, izibonelelo zeebhodi zokuhlola zegranite ze-PCB zokuqinisekisa umgangatho zicacile. Ukuthe tyaba kwazo okugqwesileyo, ukuqina, kunye nokuhambelana nezixhobo zokulinganisa kubenza babe yi-asethi yexabiso kushishino lokwenziwa kombane. Ngokutyala imali kwiibhodi zokuhlola zegranite, abavelisi banokuphucula iinkqubo zabo zokuqinisekisa umgangatho, ekugqibeleni bavelise iimveliso ezisemgangathweni zePCB kunye nokuphucula ukwaneliseka kwabathengi.
