1, Machining raug ntawm qhov chaw
Machining raug yog qhov tseeb geometric tsis ntawm qhov chaw tom qab machining, xws li cov duab, qhov loj me thiab qhov sib thooj ntawm qhov chaw. Qhov sib xws ntawm cov kev ntsuas no nrog rau qhov zoo tagnrho geometric parameters. Qhov siab dua qhov kev sib haum xeeb, qhov siab dua qhov machining raug. Lub machining raug ntawm qhov chaw feem ntau suav nrog qhov tseeb qhov tseeb, qhov tseeb thiab qhov tseeb ntawm txoj haujlwm.
1. Dimensional raug
Cov degree uas qhov tseeb qhov tseem ceeb ntawm txoj kab uas hla, qhov ntev, qhov deb thiab lwm qhov ntev ntawm qhov yog nyob ze rau qhov tseem ceeb yog qhov tseeb qhov tseeb, uas yog tswj los ntawm qhov ntev ntev.
2. Cov duab raug
Cov duab raug yog qhov kev sib haum xeeb ntawm cov duab tiag tiag thiab cov duab zoo tshaj plaws ntawm kab thiab nto ntawm ib feem. Cov khoom ntsuam xyuas ntawm cov duab raug suav nrog ncaj, flatness, roundness, cylindricity, West Bank profile thiab nto profile.
3. Qhov tseeb ntawm qhov chaw
Qhov tseeb txoj hauj lwm yog hais txog qhov tseeb txoj hauj lwm ntawm cov ntsiab lus, kab thiab qhov chaw ntawm ib feem tom qab machining thiab cov degree ntawm kev ua raws li txoj hauj lwm zoo tagnrho. Thaum lub sijhawm tshuaj xyuas, qhov sib npaug, qhov tseeb, qhov xav tau, coaxiality, symmetry, txoj hauj lwm, ncig lub voj voog thiab tag nrho cov runout yuav tsum raug tshuaj xyuas raws li cov kev cai ntawm gb/t1182-1996.
2, Machined nto zoo ntawm qhov chaw
Machining nto zoo feem ntau suav nrog cov yam ntxwv geometric ntawm machined nto thiab cov kev hloov ntawm cov khoom ntawm machined nto txheej. Qhov tseeb, qhov chaw ntawm machined qhov chaw tsis yog qhov zoo tagnrho du nto. Muaj ntau qhov sib txawv ntawm qhov chaw roughness, txias hardness thiab tawg ntawm nws nto. Cov no yuav cuam tshuam rau qhov raug, hnav tsis kam, haum qhov tseeb, kev tiv thaiv corrosion thiab qaug zog ntawm cov khoom siv kho tshuab, thiab txawm ua rau muaj kev phom sij rau kev ua haujlwm thiab lub neej ntawm cov khoom.
1. Kev cuam tshuam ntawm qhov zoo ntawm qhov hnav tsis kam ntawm qhov chaw
Qhov saum npoo roughness loj dhau lawm, qhov tseeb siab ntawm qhov sib chwv qhov chaw nce, thiab cov peaks ntxhib tom, tawg thiab txiav ib leeg, yog li kev hnav yog intensified. Yog hais tias qhov saum npoo roughness tsawg dhau, nws tseem yuav ua rau muaj kev hnav ntau ntxiv. Vim tias qhov saum npoo yog du dhau lawm, cov roj lubricating tsis tuaj yeem khaws cia, thiab cov yeeb yaj kiab roj tsis tuaj yeem tsim rau ntawm qhov chaw sib cuag, kev sib txuas molecular yog ib qho yooj yim tshwm sim, uas ua rau muaj zog hnav.
2. Kev cuam tshuam ntawm qhov zoo ntawm qhov qaug zog ntawm qhov chaw
Qhov loj dua qhov roughness, qhov ua rau muaj peev xwm tiv taus kev qaug zog. Nws muaj kev cuam tshuam zoo rau lub zog qaug zog ntawm qhov chaw nyob rau hauv alternating load. Nyob rau hauv qhov kev txiav txim ntawm alternating load, lub concave ib feem ntawm nto roughness yog ib qho yooj yim mus ua kom muaj kev ntxhov siab concentration thiab qaug zog tawg. Qhov me me ntawm qhov roughness tus nqi yog, qhov tsis xws luag yog zam, thiab qhov zoo dua qhov qaug zog ntawm lub workpiece yog; Ntawm qhov tsis sib xws, qhov rougher lub tshuab nto, qhov sib sib zog nqus cov cim rau ntawm qhov chaw, thiab qhov me me ntawm lub vojvoog hauv qab ntawm qhov striation, qhov ua rau nws muaj peev xwm tiv taus kev qaug zog.
3. Kev cuam tshuam ntawm qhov chaw zoo ntawm kev ua haujlwm raug ntawm qhov chaw
Qhov ntau dua qhov roughness ntawm qhov chaw, qhov tsawg dua qhov raug. Cov txheej txheej saum npoo muaj cov kev ntxhov siab loj, uas yuav cuam tshuam rau kev ruaj ntseg ntawm lawv qhov tseeb.
4. Kev cuam tshuam ntawm qhov zoo ntawm qhov corrosion kuj ntawm qhov chaw
Qhov rougher ntawm qhov saum npoo yog, cov tshuaj corrosive ntau dua yuav sib sau ua ke, thiab qhov tob hauv hav yog, qhov muaj zog ntawm kev nkag mus thiab corrosion yuav. Yog li ntawd, txhawm rau txhim kho corrosion kuj ntawm qhov chaw, txoj hauv kev ntau lawm yog los txo qhov roughness ntawm qhov chaw.
