Cov txheej txheem xav tau rau machining ncej qhov chaw
1. Dimensional raug
Phau ntawv xov xwm yog lub ntsiab lus tseem ceeb ntawm cov ncej, uas cuam tshuam rau kev sib hloov qhov tseeb thiab kev ua haujlwm ntawm cov ncej. Txoj kab uas hla qhov tseeb ntawm phau ntawv xov xwm feem ntau yog IT6 ~ 9 raws li nws cov ntawv thov, thiab cov ntawv xov xwm precision tuaj yeem ncav cuag nws 5.
2. Geometric raug
Qhov tseeb geometric ntawm Phau Ntawv Xov Xwm (roundness, cylindricity) feem ntau yuav tsum raug txwv rau txoj kab uas hla ntawm cov ntsiab lus siab. Rau cov uas xav tau qhov tseeb geometric siab, qhov kev tso cai tso cai tuaj yeem raug teev cais ntawm qhov kos duab.
3. Qhov tseeb ntawm qhov chaw
Nws yog hais txog lub coaxiality ntawm mating Journal ntawm cov sib dhos kis tau tus mob ib feem txheeb ze rau cov kev txhawb nqa phau ntawv ntawm lub assembled bearing, uas yog qhia los ntawm lub radial ncig runout ntawm mating phau ntawv journal mus rau lub txhawb phau ntawv journal; Raws li qhov yuav tsum tau siv, nws tau teev tias lub siab precision ncej yog 0.001 ~ 0.005mm, thaum lub dav dav precision ncej yog 0.01 ~ 0.03mm ib. Tsis tas li ntawd, muaj qhov yuav tsum tau ua rau coaxiality ntawm sab hauv cylindrical nto thiab perpendicularity ntawm axial positioning kawg lub ntsej muag thiab kab axis.
4. Nto roughness
Raws li qhov sib txawv ua haujlwm ntawm cov khoom, tuaj yeem muaj qhov sib txawv ntawm qhov roughness qhov tseem ceeb. Nrog rau kev nce ntawm lub tshuab khiav ceev thiab kev txhim kho ntawm precision, qhov saum npoo roughness tus nqi ntawm cov ncej yuav tsum tau me me thiab me.
5. Nws tsis raug tso cai siv thaum lub ntsej muag bearing yog discolored
Thaum lub npoo ntawm cov kabmob alloy yog daj, nws tsis raug tso cai siv nws. Tsis muaj denuclearization nyob rau hauv lub teev kev sib cuag lub kaum sab xis. Qhov chaw denuclearization sab nraud ntawm lub kaum sab xis yuav tsum tsis txhob ntau tshaj 10 feem pua ntawm tag nrho cheeb tsam ntawm cheeb tsam tsis sib cuag. Kev siv lub ntsej muag kawg ntawm lub iav (worm iav) thiab lub xub pwg nyom (los yog lub ntsej muag kawg ntawm lub tes tsho) yuav tsum haum ua ke, thiab nws tsis tuaj yeem kuaj xyuas nrog 0.05mm feeler gauge. Lub perpendicularity ntawm lub iav siv kawg lub ntsej muag thiab lub axis yuav tsum tau guaranteed.
6. Tiv tauj nto
Tom qab kev sib dhos, lub nplhaib sab nraud ntawm cov kabmob yuav tsum nyob rau hauv kev sib cuag nrog lub ntsej muag kawg ntawm cov kabmob npog ntawm qhov chaw kawg. Tom qab kev teeb tsa, cov kabmob dov yuav tsum tig hloov tau yooj yim thiab ruaj khov ntawm tes. Qhov sib koom ua ke ntawm cov kabmob sab sauv thiab sab qis yuav tsum tau muab tso rau ze ze thiab tsis tuaj yeem kuaj xyuas nrog lub ntsuas ntsuas 0.05mm; Thaum kho cov kabmob bush nrog tus pin nrhiav tus pin, kev faib thiab tus pin faib yuav tsum tau ua nyob rau hauv cov xwm txheej uas qhov qhib qhov chaw thiab lub ntsej muag kawg ntawm cov hav txwv yeem yog flush nrog qhov qhib qhov chaw thiab qhov kawg ntawm lub ntsej muag ntawm cov kabmob uas cuam tshuam. Tus pin yuav tsis loosen tom qab tau tsav.
Cov kev xav tau ntawm cov ncej ncej yog qhov siab, yog li cov txheej txheem machining ntawm cov ncej yuav tsum nruj dua, txhawm rau kom ntseeg tau tias cov cuab yeej siv tshuab tuaj yeem ua haujlwm zoo dua thiab muaj kev pabcuam ntev dua.
