Yuav ua li cas feem ntau cov tuag nyob rau hauv ib tug ncaj-los ntawm hlau kos tshuab yuav hloov?
Tsis muaj tus qauv ruaj khov rau lub voj voog hloov tuag ntawm ib qho ncaj -los ntawm lub tshuab nqus hlau. Nws tsuas yog nyob ntawm peb yam tseem ceeb: cov khoom siv, cov txheej txheem tsis, thiab cov khoom siv tuag. Tshwj xeeb, nws tuaj yeem muab faib ua cov xwm txheej hauv qab no:
Los ntawm cov khoom ua tiav:
- Stainless hlau xaim (hardened): Stainless hlau muaj siab hardness, uas ua rau tseem ceeb hnav ntawm tuag. Yog tias ua tiav cov hlau tsis muaj steel hlau nrog ib txoj kab uas hla ntawm Ntau dua lossis sib npaug li 1 hli siv cov cemented carbide zoo tib yam tuag, lub voj voog hloov feem ntau yog 20-50 teev; yog tias ua haujlwm zoo- txoj kab uas hla (tsawg dua lossis sib npaug li 0.5mm), qhov tuag yuav ploj sai dua, thiab yuav tsum tau hloov pauv txhua 10-30 teev.
- Stainless hlau hlau (mos temper): Mos temper stainless hlau xaim muaj zoo ductility thiab tsis tshua muaj hnav, ncua kev hloov lub voj voog ntawm zoo tib yam cemented carbide tuag rau 50-100 teev.
Classified los ntawm cov khoom pwm:
- Ordinary cemented carbide pwm: Tus nqi siab -kev ua tau zoo, nruab nrab hnav tsis kam, thiab hom siv feem ntau hauv khw. Lub voj voog hloov pauv yog nyob ntawm lub sijhawm ua raws li cov khoom tau hais los saum toj no.
- Siab -kev ua tau zoo cemented carbide pwm (xws li ultra- cov nplej zoo cemented carbide): Kev hnav tsis kam yog txhim kho los ntawm 3-5 zaug, thiab lub voj voog hloov tuaj yeem txuas ntxiv mus rau 100-300 xuab moos, haum rau kev tsim khoom loj.
- Pob zeb diamond pwm: Lub zog hnav tsis kam, tshwj xeeb tshaj yog rau cov hlau tsis muaj hlau ua. Lub voj voog hloov pauv tuaj yeem ncav cuag 500-1000 teev, tab sis tus nqi siab dua, thiab lawv feem ntau yog siv rau kev nplua - txoj kab uas hla lossis siab - daim ntawv thov kev ua tiav.
Distinguished los ntawm cov txheej txheem parameter:
- Yog tias qhov txo qis hauv cheeb tsam thaum lub sij hawm xaim hluav taws xob siab dhau lawm (txoj kab uas hla loj txo ib qho dhau), qhov nrawm nrawm nrawm, thiab cua txias thiab lubrication tsis txaus, qhov hnav tus nqi ntawm qhov tuag yuav nce ntxiv, thiab lub voj voog hloov yuav luv los ntawm 30% -50%. Conversely, tsim nyog tswj qhov txo qis hauv cheeb tsam thiab ua kom lub lubrication txaus tuaj yeem ua kom ntev lub neej tuag.
Tswv yim kev txiav txim:
Dhau li ntawm kev txiav txim siab lub sijhawm siv, ib txoj hauv kev ncaj nraim ntawm kev txiav txim siab yog saib xyuas qhov zoo ntawm cov khoom tiav:
Thaum lub npoo ntawm cov hlau tiav tiav pom muaj khawb, burrs, lossis dhau txoj kab uas hla hloov pauv;
Los yog thaum qhov zaus ntawm cov hlau tawg thaum lub sij hawm cov txheej txheem kos duab nce ntau, los yog lub zog ntawm daim duab nce txawv txav, qhov tuag yuav tsum tau hloov tam sim ntawd.
