Bambanci tsakanin granite da polymer ba ɗaya ne kawai na yawa ko bayyanar ba; ya ta'allaka ne a cikin mahimman kaddarorin jiki waɗanda ba za'a iya sasantawa ba don daidaiton darajar awo:

1. Thermal Expansion (CTE): Wannan shine babban rauni guda ɗaya na kayan polymer. Filastik suna da Coefficient of thermal Expansion (CTE) sau da yawa sama da na granite sau goma. Ko da ƙananan sauye-sauye a cikin zafin daki, waɗanda suka zama ruwan dare a wajen dakunan tsabta na soja, suna haifar da gagarumin canje-canje mai girma a cikin robobi.

Don ma'auni masu ƙarfi ko gwaji kusa da tushen jijjiga, ɗimbin granite yana ba da mafi girman ɗaukar girgiza da jirgin sama mai shuru.

Ƙananan Girma, Babban Bukatun

Hujjar cewa dandalin "ƙananan girman" ba shi da sauƙi ga waɗannan batutuwa yana da kuskure. A cikin ƙananan dubawa, daidaitaccen tsarin dangi shine sau da yawa mafi girma. Za a iya keɓance ƙaramin matakin dubawa don duba microchip ko na'urar gani mai kyan gani, inda bandejin haƙuri yana da matsewa.

Don ƙananan ayyuka masu ƙima (misali, taro na asali ko ƙaƙƙarfan gwaji na inji), dandamali na polymer na iya bayar da na wucin gadi, madaidaicin farashi.

Koyaya, ga kowane aikace-aikacen inda:

• Dole ne a cika ka'idodin ASME ko DIN.
• Haƙuri yana ƙasa da microns 5.
• Kwanciyar kwanciyar hankali na dogon lokaci ba za'a iya sasantawa ba (misali, hangen na'ura, tsarin CMM, gwajin gani).
