Yiziphi izilinganiso kanye nemininingwane evamile yezisekelo ze-granite ezisetshenziswa kuma-CMM?

 

Izisekelo zegranite ziyizingxenye ezibalulekile emhlabeni wemishini yokulinganisa ehlanganisiwe (ama-CMM), enikeza ipulatifomu ezinzile neqondile yemisebenzi yokulinganisa. Ukuqonda ubukhulu obujwayelekile kanye nemininingwane yalezi zisekelo zegranite kubalulekile ukuqinisekisa ukusebenza kahle kanye nokunemba ezinhlelweni zakho zokulinganisa.

Ngokuvamile, izisekelo ze-granite ziza ngobukhulu obuhlukahlukene, ngobukhulu obujwayelekile obusukela ku-300mm x 300mm kuya ku-2000mm x 3000mm. Ukukhetha usayizi ngokuvamile kuzoncika ezidingweni ezithile ze-CMM kanye nohlobo lokulinganisa okwenziwayo. Izisekelo ezinkulu zifanelekela ukukala izingxenye ezinkulu, kanti izisekelo ezincane zifanelekela ukusetshenziswa okuncane kakhulu.

Ngokuqondene nobukhulu, izisekelo zegranite ngokuvamile ziphakathi kuka-50 mm no-200 mm. Izisekelo ezijiyile zithuthukisa ukuzinza futhi zinciphise ingozi yokuguquka ngaphansi komthwalo, okubalulekile ekugcineni ukunemba kokulinganisa. Isisindo sesisekelo segranite naso siyinto okufanele icatshangelwe, njengoba izisekelo ezisindayo zivame ukunikeza ukumuncwa okungcono kokushaqeka, okuqhubeka nokuthuthukisa ukunemba kokulinganisa.

Ukuphela kobuso besisekelo se-granite kungenye imininingwane ebalulekile. Ukuphela kobuso obujwayelekile besisekelo se-granite se-CMM cishe kungama-micron angu-0.5 kuya ku-1.6, okuqinisekisa ukuthi ubuso buyisicaba futhi bubushelelezi ukuze kuncishiswe amaphutha okulinganisa. Ngaphezu kwalokho, ukubekezelela ukuthamba kubalulekile, ngezincazelo ezivamile ezisukela ku-0.01 mm kuya ku-0.05 mm, kuye ngezidingo zokusetshenziswa.

Izinto zegranite ngokwazo zinokuqina okuhle kakhulu, ukwanda okuphansi kokushisa kanye nokumelana nokuguguleka, okwenza kube ukukhetha okuhle kakhulu ezindaweni zokulinganisa ngokunemba. Izinhlobo ezivame kakhulu zegranite ezisetshenziswa kulezi zindawo zokubeka zihlanganisa igranite emnyama, ethandwa kakhulu ngenxa yokuqina kwayo kanye nobuhle bayo.

Ngamafuphi, lapho ukhetha isisekelo se-granite se-CMM, usayizi, ukujiya, ukuqeda ubuso, kanye nezakhiwo zezinto kumele kucatshangelwe ukuqinisekisa amazinga aphezulu okunemba nokuthembeka kokulinganisa.
