Kushandiswa kwegranite sehwaro hweCoordinate Measuring Machines (CMM) itsika inogamuchirwa muindasitiri yekugadzira.Izvi zvinodaro nekuti granite ine yakanakisa kugadzikana kwemafuta, inova hunhu husingakoshi hwekuyera kuyerwa kwemhedzisiro muCMM.Muchinyorwa chino, isu tichaongorora kuti kugadzikana kwekupisa kweiyo granite base kunokanganisa sei kuyerwa kwemhedzisiro yeCMM.
Kutanga, zvakakosha kuti unzwisise kuti kugadzikana kwekushisa kunorevei.Kugadzikana kwemafuta (Thermal Stability) zvinoreva kugona kwechinhu kushingirira kushanduka kwekushisa pasina shanduko huru muchimiro chayo chemuviri nemakemikari.Panyaya yeCMM, kugadzikana kwekupisa kunoenderana nekugona kwegirenati chigadziko kuchengetedza tembiricha isingaperi kunyangwe shanduko munzvimbo dzakapoteredza.
Kana CMM iri kushanda, michina inogadzira kupisa, izvo zvinogona kukanganisa kuyerwa kwemhedzisiro.Izvi zvinodaro nekuti kuwedzera kwemafuta kunoitika kana chinhu chadziyirwa, zvichikonzera shanduko yehuyero iyo inogona kutungamirira mukuyerwa kukanganisa.Naizvozvo, zvakakosha kuti urambe uchidziya tembiricha yepasi kuti uve nechokwadi chekuyerwa uye kuenderana kwemhedzisiro.
Iko kushandiswa kwegranite sehwaro hweCMM kunopa akati wandei mabhenefiti.Granite ine yakaderera coefficient of thermal kuwedzera, zvichireva kuti haina kuwedzera zvakanyanya kana ichiiswa kune tembiricha shanduko.Iine high thermal conductivity inosimudzira yunifomu tembiricha kugovera pahwaro.Uyezve, granite's low porosity uye thermal mass inobatsira kudzora kushanduka kwetembiricha uye kuderedza mhedzisiro yekushanduka kwekushisa kwezvakatipoteredza pamhedzisiro yekuyera.
Granite zvakare chinhu chakanyanya kugadzikana chinopokana deformation uye inochengetedza chimiro chayo kunyangwe painenge ichiratidzwa kune mechanical stress.Ichi chivakwa chakakosha mukuona kumira kwakaringana kwemakina emuchina, ayo anogona kukanganisa zvakanyanya mibairo yekuyera.
Mukupfupisa, kugadzikana kwekupisa kwegirenati kwakakosha pakurongeka uye kurongeka kwezviyero zveCMM.Kushandiswa kwegranite kunopa chigadziko chakasimba uye chakasimba chinochengetedza kutonhora kunogara uye kupikisa kuchinja nekuda kwezvinhu zvekunze.Nekuda kweizvozvo, inobvumira muchina kuunza kwakaringana uye kunoenderana kuyerwa mhedzisiro, kuvandudza chigadzirwa mhando uye kuderedza mutengo wekugadzira.
