Cov kev xav tau rau cov hlau shafts suav nrog qhov tseeb qhov tseeb, geometric duab raug, kev ua haujlwm raug thiab qhov roughness:
Dimensional raug : Txoj kab uas hla qhov tseeb ntawm phau ntawv journal feem ntau yog IT 6-9, thiab cov ntawv xov xwm precision tuaj yeem ncav cuag IT.
Geometric duab raug: Lub roundness thiab cylindricity ntawm phau ntawv journal yuav tsum tau txwv rau qhov ntau ntawm txoj kab uas hla kam rau ua.
Kev ua haujlwm ntawm qhov raug: Lub coaxiality ntawm cov ntaub ntawv sib txuam ntawm cov khoom sib txuas sib txuas nrog rau cov ntawv xov xwm txhawb nqa ntawm cov kabmob sib dhos yog {{0}}}001 ~ 0.005mm rau high-precision shafts thiab 0.01 ~ 0.03mm rau dav dav precision shafts.
Deg roughness : Lub nto roughness ntawm spindle phau ntawv journal ntawm cov cuab yeej siv tshuab zoo tib yam yog Ra{0}}.16 ~ 0.63um. Nrog rau kev txhim kho ntawm lub tshuab ceev thiab qhov tseeb, qhov kev xav tau ntawm qhov chaw roughness tau me dua thiab me dua.
