Yuav ua li cas tswj cov ntug chipping hauv iav sib tsoo
May 10, 2022
Qhov teeb meem feem ntau ntsib thaum sib tsoo iav yog qhov nyiaj ntawm ntug chipping tshaj qhov ntau, yog li vim li cas ntug chipping tshwm sim? Yog vim li cas yog tias iav muaj amorphous thiab irregular non-crystalline qauv, uas txhais tau hais tias ntug chipping yog inevitable thiab random thaum sib tsoo iav. Cov tswv yim txiav txim siab cov txiaj ntsig tso tawm hauv kev sib tsoo. Plaub yam tseem ceeb ntawm cov khoom siv yog cov khoom siv, cov cuab yeej, cov khoom siv, thiab cov khoom ua haujlwm. Cov ntug chipping yog qhov tshwm sim ntawm kev sib xyaw ua ke ntawm cov yam ntxwv no.
Cov yam ntxwv uas cuam tshuam rau kev sib tsoo cov nyhuv yog: txoj kab uas hla, grit, groove kaum sab xis, runout (concentricity).
1. Txoj kab uas hla
Qhov me me ntawm txoj kab uas hla ntawm kev sib tsoo lub log nrog qhov qis sib tsoo linear tshaj tawm, uas yuav ua rau muaj kev sib tsoo ntau dua ntawm ib qho abrasive ntawm cov xuab zeb nto, yog li ua rau kev sib tsoo quab yuam thiab ua kom yooj yim los tsim cov npoo tawg.
Yog li ntawd, txoj kab uas hla ntawm lub taub hau sib tsoo yuav tsum yog qhov tsim nyog tsim ntawm txoj kab uas hla ntawm lub taub hau sib tsoo.
2. Nyuaj
Lub coarser lub grit loj txhais tau hais tias qhov tsawg abrasive hais nyob rau saum npoo, uas kuj ua rau kom qhov sib tsoo tus nqi ntawm abrasive thaum lub sij hawm sib tsoo, yog li ua rau lub sib tsoo quab yuam thiab ua rau nws muaj feem yuav ua rau cov ntug breakage.
Txhawm rau kom tswj tau qhov zoo ntawm ntug kev tawg ntawm qhov xav tau, lub pob zeb diamond grit loj yuav tsum raug xaiv kom tsim nyog.
3. Groove Angle
Lub kaum sab xis ntawm qhov zawj tiav yuav cuam tshuam rau qhov nyiaj ntawm ntug kev tawg mus rau qee qhov, vim tias lub log sib tsoo yuav ua rau muaj kev ntxhov siab thiab kev ntxhov siab hauv kev sib tsoo cov iav, thiab kev ntxhov siab shear yog qhov loj tshaj plaws ntawm cov ntug tawg. Txo lub kaum sab xis ntawm qhov zawj tuaj yeem ua rau lub zog hloov mus rau qhov kev ntxhov siab compressive thiaj li txo cov ntug kev tawg.
Txawm li cas los xij, nws yuav tsum raug sau tseg tias qhov txo qis ntawm lub kaum sab xis yuav cuam tshuam cov nti tawm mus rau qee qhov, yog li nws yog qhov tseem ceeb los tswj lub kaum sab xis kom tsim nyog.
4. Concentricity
Concentricity kuj yog qhov ntaus loj uas peb feem ntau hais, qhov loj dua qhov sib tsoo, qhov tsis ruaj khov ntawm lub taub hau sib tsoo, tus naj npawb ntawm abrasive koom nrog kev sib tsoo txo, ua rau ib qho abrasive sib tsoo ntim, loj zog, ua rau lub cev qhuav dej ntawm qhov yooj yim dua. los tsim.
Yog li ntawd, nruj me ntsis tswj qhov concentricity ntawm lub taub hau sib tsoo kuj yog qhov tseem ceeb tshaj plaws.
