1.Kev ntsuas ntawm txoj kab uas hla thiab tawm-ntawm-roundness
Qhov txoj kab uas hla thiab tawm ntawm qhov sib txawv ntawm cov hlau xaim hlua ntsuas yuav tsum tau ntsuas siv lub vernier caliper nrog lub puab tsaig dav, thiab kev ntsuas yuav tsum tau ua nyob rau hauv cov xwm txheej tsis nruj. Ntawm ob ntu uas nyob ib sab rau ib leeg rau tsawg kawg 1m ntawm txoj kab ncaj nraim 15m deb ntawm qhov kawg ntawm txoj hlua hlau, coj ob qhov txiaj ntsig ntsuas perpendicularly rau ib leeg ntawm tib seem, thiab qhov nruab nrab ntawm plaub qhov kev ntsuas yuav raug siv raws li qhov tseeb ntsuas txoj kab uas hla ntawm txoj hlua hlau. Qhov sib piv ntawm qhov sib txawv siab tshaj plaws ntawm txoj kab uas hla ntsuas ntawm tib seem ntawm cov hlua hlau mus rau qhov nominal txoj kab uas hla yog hu ua qhov tawm-ntawm-roundness ntawm cov hlua hlau.
2.Kev ntsuas qhov ntev
Qhov ntev ntawm txoj hlua steel hlau yuav tsum ntsuas nyob rau hauv tsis muaj load. Cov kev cai tshwj xeeb: Txoj kev ntsuas qhov ntev ntawm txoj hlua hlau yuav tsum tau pom zoo ntawm tus neeg muag khoom thiab tus neeg yuav khoom.
3.Qhov zoo
Qhov saum npoo zoo ntawm cov hlua hlau thiab nws cov hlua yog tshuaj xyuas los ntawm tes thiab kev soj ntsuam pom.
4.Kev ntsuas qhov hnyav
Tag nrho qhov hnyav ntawm cov hlua hlau suav nrog qhov hnyav ntawm cov hlua hlau, cov ntaub ntawv thiab cov khoom ntim, thiab yuav tsum tau ntsuas nrog cov ntsuas ntsuas ntsuas.
