Thaum xaiv ib lub voj voog txiav, muaj plaub yam tseem ceeb los xav txog. Kuv tau teeb tsa lawv rau hauv qhov yooj yim tshaj plaws thiab yooj yim tshaj plaws version rau kev siv ncaj qha, ua rau lawv nkag siab yooj yim ntawm ib nrais muag.
I. Ua ntej, xav txog yam khoom uas koj txiav
1.Kev txiav ntawv, tsis yog- ntaub npuag, ntaub mos, daim txhuam cev, roj hmab
Kev xaiv: Siab-Speed Steel (HSS) / 9CrSi cuab yeej steel
Yog vim li cas: zoo toughness, sharpness, yooj yim regrinding, thiab nqi tsawg.
2. Txiav yas zaj duab xis, BOPP, PET, txhuas ntawv ci, iav fiber ntau, tshuaj fiber ntau, ntaub pua plag
Kev xaiv: Cemented carbide (tungsten steel)
Yog vim li cas: Ultra hnav-resistant, tsis xav tau riam sharpening rau lub sij hawm ntev, haum rau siab - ceev slitting
3.Kev txiav cov zaub mov (nqaij, txiv hmab txiv ntoo, zaub, qhob cij), tshuaj, lossis ua haujlwm hauv qhov chaw ntub dej
Kev xaiv: Stainless hlau 420/440/3Cr13
Yog vim li cas: xeb-resistant, huv si, yooj yim los ntxuav, thiab ua tau raws li cov zaub mov- qib yuav tsum tau.
4. Txiav cov ntaub nplaum xws li tus kheej - cov ntawv nplaum, daim kab xev, thiab daim ntawv cim npe
Kev xaiv: Coated hniav (TiN / DLC) los yog ceramic hniav
Yog vim li cas: Tsis yog - nplaum, ntxuav qhov chaw, tsis muaj hlau kos.
5.High-precision, plua plav-dawb, thiab cov khoom siv hluav taws xob
Kev xaiv: Ceramic hniav
Yog vim li cas: xeb-dawb, tsis yog- conductive, tsis tshua muaj hnav-resistant, tab sis tsis yooj yim rau tee thiab cuam tshuam.
II. Xyuas qhov txiav ceev
Tsawg ceev, phau ntawv ua haujlwm / cov tshuab yooj yim
→ Cov pa roj carbon steel, cov cuab yeej steel, thiab siab - steel ceev txaus.
Siab -kev sib hloov ceev, ntau lawm
→ Cemented carbide yuav tsum tau siv; txwv tsis pub, nws yuav hnav sai sai.
III. Xyuas seb puas yuav tsum tau tiv thaiv xeb thiab kev tu cev
Rau qhov chaw ntub dej, dej- raug mob, acid- puag ncig puag ncig, thiab kev siv zaub mov thiab tshuaj
→ Stainless hlau yog nyiam vim nws yog xeb - pov thawj thiab nyab xeeb.
Rau kev cob qhia qhuav thiab dav siv slitting
→ Ob leeg siab -ceev steel thiab tungsten steel yog siv tau.
