Txiav-tawm thiab grooving rau cov khoom sib txawv

 

Thaum nws los txog rau txiav tawm thiab grooving operations, cov khoom muaj peev txheej zoo heev cov cuab yeej xaiv, ntxig geometry, thiab machining lub tswv yim. Kab lus no qhia txog cov txheej txheem pom zoo rau kev siv cov khoom siv ntau yam, suav nrog cov khoom siv ntau yam, muaj cov khoom siv titanium, thiab cov khoom tawv tawv.

 

Kuv txiav-tawm thiab grooving ntawm txhuas thiab tsis-ferrous hlau

Cov uas tsis muaj hlau, xws li txhuas, tooj liab, thiab tooj dag, yog cov khoom muag. Txawm li cas los xij, tej yam alloys alloys-tshwj xeeb tshaj yog cov uas muaj siab ntsoos (Si) cov ntsiab lus, zoo li 13% SI-tuaj yeem yog cov abrasive heev. Rau cov ntaub ntawv zoo li no, ntxig nrog cov ntawv txiav ntse yog qhov tseem ceeb kom ua tiav kev txiav siab ceev thiab siv lub neej ntev.

 

Txhawm rau muab cov ntaub ntawv txiav ntse, zoo ib yam li RO-style geometry, av ntxig sawv tseev feem ntau yuav tsum tau ua. Cov kev pom zoo kom tau qhab nia yog tsis ruaj khov los yog maj mam co carbide kom txo kev sib txhuam thiab hnav. Rau qhov uas yuav tsum muaj cov chaw zoo dua qub, polycrystalline pob zeb diamond (PCD) Tipped cov ntxig yog qhov pom zoo heev. Cov cuab yeej no ua kom cov tshuab nrawm nrawm nrog cov cuab yeej zoo thiab ua tiav zoo.

 

 

Ii cut-tawm thiab grooving ntawm tshav kub-resistant super alloys (hrsa)

HRSAS feem ntau muab faib ua peb pawg: Nickel-raws li, hlau raws, thiab cobalt-based alloys. Txhua pab pawg muaj cov khoom siv lub cev sib txawv thiab tshuab ua tus cwj pwm. Kev kho kom sov xws li anealing lossis kev laus cuam tshuam rau machinability, nrog cov khoom tawv tawv sib txawv ntawm 150 thiab 440 hb nyob ntawm cov txheej txheem kho.

 

Nyob rau hauv dav dav, hrsas nyuaj rau kev siv lub tshuab tsis yooj yim dua cov hlau uas muaj cov hlau thiab stainless. Rau kev ua tau zoo tshaj plaws, cov pom zoo pom zoo nkag geometries yog -gf thiab -tf hom. Thaum qhov kev txiav siab ceev yog qhov xav tau, cov hluav taws xob tuaj yeem txhim kho kev tsim khoom lag luam, ua tsaug rau lawv qhov kev ua haujlwm siab tsis kam thiab hnav kev ua tau zoo.

 

 

III txiav-tawm thiab grooving ntawm titanium alloys

 

▲ Daim duab 3Txiav-tawm thiab grooving ntawm titanium alloys

 

Titanium alloys feem ntau yog machinys tom qab annealing los yog kev daws teeb meem thiab kev ua kom laus, ua rau muaj kev nyuaj siab ntawm 250 thiab 440 HB. Cov ntaub ntawv no nyuaj rau tshuab tshaj cov hlau uas muaj cov hlau lossis cov hlau tsis muaj zog, tso cov kev xav tau ntau dua ntawm cov cuab yeej.

 

Nws raug nquahu kom siv cov carbide carbide ntxig nrog cov ntse txiav cov npoo, xws li cov uas muaj -gf geometry. Vim yog titanium txoj kev nyiam ua lag luam ntev, cov chips txuas ntxiv, ua tau zoo chip tswj yog qhov tseem ceeb. Txhawm rau kom ntseeg tau zoo tshaj tawm thiab txuas ntxiv cuab tam lub neej, kev siv cov tshuab siab siab txias rau lub tshuab tau pom zoo.

 

 

IV HARDICATION MACHINING

Niaj hnub tsim tsim kev tsim nyog yuav tsum tau ua tiav machining hauv ib qho teeb tsa, ua rau kev cog lus rau kev ua kom muaj zog hloov. Hauv cov ntawv thov zoo li no, kev txiav cov ntaub ntawv xws li Cubic Boron Nitride (CBN) tseem txhawb cov khoom lag luam los ntawm kev hloov cov khoom sib tsoo.

 

CBN cov cuab yeej tuaj yeem siv tshuab ob qho tib si los ntawm-hardened thiab induction thiab inducted-hardened qhov chaw nrog cov tawv tawv muaj txij li 50 txog 65 teev. Rau grooving operations, -s geometry cov kev pom zoo, thaum -ée geometry ntxig yog haum rau profiling. Rau cov nplooj kuab me me, CBN-TIPPed graining ntxig yog qhov zoo tagnrho. Cov cuab yeej no tau tsim los rau cov kev txiav txuas ntxiv thiab cuam tshuam, muab cov npoo zoo ua tiav thiab kaw qhov raug.
