Qhov zoo ntawm cov kav dej cylinder

1. Txhim kho qhov roughness kom ua tiav Ra ​​Tsawg dua lossis sib npaug rau 0.08µ Txog m.
2. Qhov tseeb roundness, ovality yuav tsawg dua los yog sib npaug rau 0.01mm.
3. Txhim kho deg hardness, tshem tawm kev ntxhov siab deformation, thiab nce hardness los ntawm HV ntau dua los yog sib npaug rau 4 degree
4. Tom qab ua tiav, muaj cov txheej txheem kev ntxhov siab seem, uas ua rau kom qaug zog ntawm 30%.
5. Txhim kho qhov zoo ntawm qhov haum, txo qhov hnav, thiab txuas ntxiv lub neej kev pabcuam ntawm cov khoom, tab sis cov nqi ua haujlwm ntawm cov khoom raug txo kom tsawg.
