Nrog rau kev tsim cov thev naus laus zis, carbide inserts tau dhau los ua cov khoom lag luam ntawm CNC machining cov cuab yeej. Ib daim ntawv ntsuam xyuas pom tias carbide inserts suav rau qhov feem ntau ntawm kev muag khoom ntawm cov cuab yeej carbide, txog 50%. Carbide inserts yog siv rau ntau lub tshuab CNC tam sim no. Vim li cas thiaj xaiv carbide inserts ntawm CNC machining? Dab tsi yog daim ntawv thov thiab kev txhim kho yav tom ntej ntawm carbide inserts ntawm CNC machining? Yog tias koj muaj cov lus tsis txaus siab no, thov tsis txhob nco cov lus no. Nws yuav hais cov lus teb hauv cov ntsiab lus.

1. Vim li cas thiaj xaiv carbide inserts ntawm CNC machining?

Carbide inserts, raws li lub npe qhia, nws cov khoom tseem ceeb yog cemented carbide. Cemented carbide yog ua los ntawm refractory hlau carbide thiab hlau binder hmoov tom qab ua tiav. Vim hais tias cov hlau carbides muaj qhov siab melting point, siab hardness thiab zoo tshuaj stability, cemented carbides muaj ib tug loj npaum li cas ntawm refractory hlau carbides kuj muaj cov yam ntxwv ntawm cov refractory hlau carbides. Yog li ntawd, carbide inserts muaj siab hardness, hnav tsis kam, thiab kub tsis kam. Lub hardness ntawm feem ntau siv carbide inserts yog 89 ~ 93HRA, uas yog siab tshaj hardness ntawm high-ceev steel (83 ~ 86.6HRA). Thiab carbide inserts yog resistant rau kub kub. Carbide inserts tuaj yeem txiav cov khoom ntawm qhov kub ntawm 800 ~ 1000 ℃. Qhov kev ua tau zoo ntawm cov carbide inserts yog ntau dua li cov cuab yeej siv high-speed steel. Lub durability ntawm carbide inserts yog ob peb zaug ntawm lwm cov inserts. Thaum lub sijhawm ua haujlwm zoo ib yam, carbide inserts tuaj yeem ua rau kev txiav ceev los ntawm 4 mus rau 10 zaug.

2. Daim ntawv thov ntawm carbide inserts ntawm CNC machining

Vim lub superior hardness thiab kub tsis kam ntawm carbide inserts. Yog li ntawd, CNC machining feem ntau xaiv carbide tej cuab yeej rau lathes txiav cov ntaub ntawv. Cov ntaub ntawv sib xyaw, cov khoom siv yas, cov khoom siv iav organic thiab cov ntaub ntawv hlau tsis muaj hlau nyob hauv kev ua lag luam yog tag nrho cov txiav thiab ua tiav los ntawm cov cuab yeej txiav carbide rau lathes. Cemented carbide tau muab faib ua ob pawg: tungsten-cobalt alloy (YG) thiab tungsten-cobalt-titanium alloy (YT). Tungsten-cobalt alloys muaj zoo toughness. Cov cuab yeej ua los ntawm tungsten-cobalt alloys yog ib qho yooj yim rau deform nyob rau hauv cov txheej txheem txiav, txiav yog lub teeb thiab ceev, thiab cov chips tsis yooj yim rau lo rau riam. Yog li, feem ntau, peb yuav xaiv cov cuab yeej ua los ntawm tungsten-cobalt alloy los ua stainless hlau. Tungsten-cobalt-titanium alloy yog hnav-tiv taus ntau dua li tungsten-cobalt alloy nyob rau hauv qhov kub thiab txias. Tab sis nws yog nkig thiab tsis resistant rau tej yam. Yog li ntawd, peb yuav xaiv cov cuab yeej ua los ntawm tungsten-cobalt-titanium alloy los ua cov ntaub ntawv yas, xws li hlau.

3. Kev txhim kho yav tom ntej ntawm carbide inserts ntawm CNC machining

Nrog kev txhim kho txuas ntxiv ntawm kev tshawb fawb thiab thev naus laus zis thiab kev txhim kho tas mus li ntawm qib ntau lawm, kev hloov pauv ntawm cov cuab yeej siv tshuab los ntawm cov tshuab zoo tib yam rau CNC tshuab yog ib qho kev tsis tuaj yeem. Carbide txiav cov cuab yeej rau lathes ua lub luag haujlwm tseem ceeb hauv kev hloov kho thiab txhim kho cov qauv kev lag luam. Carbide txiav cov cuab yeej rau tshuab dhos tuaj yeem txhim kho cov khoom lag luam tawm los thiab zoo. Kev tswj tus lej tshuab yog ib qho kev hloov kho tshiab ntawm kev lag luam tshuab, thiab qhov kev thov rau cov cuab yeej tswj tus lej tseem yuav nthuav dav. Raws li ib qho tseem ceeb ntawm CNC hlau txiav tshuab, carbide inserts yuav tsav cov neeg siv khoom xav tau rau CNC cov cuab yeej, txawm tias nws yog cov khoom xav tau ntawm cov cuab yeej siv tshuab los yog qhov xav tau ntxiv rau cov cuab yeej siv tshuab tshiab txhua xyoo. Nyob rau tib lub sijhawm, carbide inserts yog consumables. Yog hais tias cov carbide inserts tau hnav mus rau ib qho twg, lawv yuav tsum tau hloov lub sijhawm. Yog li ntawd, qhov kev thov rau carbide inserts nyob rau hauv kev ua lag luam tseem muaj ntau heev.
