Muaj ntau qhov kev faib tawm ntawm cov cuab yeej carbide siv hauv kev txiav ntoo, xws li cov saw saws, sawb band saws, milling cutters, luam riam, thiab lwm yam. Txawm hais tias muaj ntau hom saws, txhua hom cuab yeej yog raws li cov khoom siv thiab cov khoom siv. ntawm ntoo raug txiav. Yam ntxwv: Xaiv cov carbide tsim nyog. Cov hauv qab no teev cov carbide sib xws rau cov khoom sib txawv.

1. Particle board, board ntom ntom, thiab particle board. Cov laug cam no feem ntau yog tsim los ntawm cov ntoo, tshuaj nplaum, thiab melamine panels. Lawv yog cov yam ntxwv los ntawm cov tawv veneer panels, siab cov ntsiab lus kua nplaum nyob rau hauv lub puab txheej, thiab ib tug ib feem ntawm cov impurities nyuaj. Thaum lub sij hawm txiav cov txheej txheem, cov rooj tog zaum muaj cov kev cai nruj ntawm cov burrs ntawm ntu txiav, yog li no hom ntawm ntoo board feem ntau xaiv cemented carbide nrog Rockwell hardness ntawm 93.5-95 degrees. Cov khoom siv hlau feem ntau yog xaiv tungsten carbide thiab tsawg-density carbide nrog cov nplej loj ntawm tsawg dua 0.8um. Nyob rau hauv xyoo tas los no, vim qhov hloov pauv thiab hloov pauv ntawm cov ntaub ntawv, ntau lub tuam txhab rooj tog tau maj mam siv cov pob zeb diamond sib xyaw ua ke es tsis txhob carbide saw hniav rau txiav hauv vaj huam sib luag hluav taws xob txiav saws. Cov pob zeb diamond sib xyaw muaj qhov nyuaj dua thiab siv tau ntev dua. Thaum lub sij hawm txiav cov txheej txheem ntawm cov khoom vaj huam sib luag, cov nplaum thiab corrosion kuj zoo dua li cov cemented carbide. Raws li kev txheeb xyuas kev ua haujlwm ntawm kev ua haujlwm, kev pabcuam lub neej ntawm cov pob zeb diamond pom hniav yog tsawg kawg 15 npaug ntawm cov cemented carbide pom hniav.

2. Khoom ntoo Khoom ntoo feem ntau yog hais txog ntau hom ntoo cog ntoo. Ntau hom ntoo muaj qhov sib txawv txiav nyuaj. Feem ntau cov tuam txhab lag luam feem ntau xaiv cov alloys nrog 91-93.5 degrees. Piv txwv li, xyoob ntoo knots yog ib qho nyuaj tab sis cov ntoo yog yooj yim, yog li ib tug alloy nrog ib tug hardness ntawm ntau tshaj 93 degrees feem ntau yog xaiv los xyuas kom meej zoo sharpness; cav nrog ntau nti yog unevenly stressed thaum lub sij hawm txiav, yog li cov hniav Thaum ntsib cov caws pliav, nws yooj yim heev ua rau cov ntug nti. Yog li ntawd, ib tug alloy ntawm 92-93 degrees feem ntau yog xaiv los xyuas kom meej ib tug tej yam sharpness thiab ib tug tej yam degree ntawm nti kuj. Ntoo uas tsis tshua muaj caws pliav thiab cov ntoo sib xws zoo dua. Ib qho alloy nrog hardness saum 93 degrees yuav raug xaiv. Ntev npaum li kev hnav ua haujlwm siab thiab ua kom pom tseeb, nws tuaj yeem txiav tau ntev; cov ntoo ib txwm nyob rau sab qaum teb yuav tsim cov ntoo khov vim qhov txias txias thaum lub caij ntuj no, thiab cov ntoo khov yuav ua rau cov ntoo khov. Thiab txiav cov ntoo khov khov rau hauv qhov chaw txias heev yog qhov yuav ua rau chipping, yog li qhov no, alloys nrog 88-90 degrees feem ntau yog xaiv rau kev txiav.

3. Impurity ntoo: Hom ntoo no muaj cov ntsiab lus siab ntawm impurities. Piv txwv li, cov laug cam siv rau ntawm qhov chaw tsim kho feem ntau muaj cov ntsiab lus ntawm cov cement, thiab cov laug cam siv rau cov rooj tog zaum disassembly feem ntau muaj cov ntsia hlau los yog cov ntsia hlau. Yog li ntawd, thaum cov hniav tsoo ib yam khoom nyuaj thaum lub sij hawm txiav, Nws yuav ua rau chipping lossis tawg ntawm ntug, yog li alloys nrog qis hardness thiab siab dua toughness feem ntau yog xaiv rau txiav hom ntoo. Hom alloy no feem ntau xaiv tungsten carbide nrog nruab nrab mus rau ntxhib grain loj, thiab cov ntsiab lus ntawm cov binder theem yog siab heev. Rockwell hardness ntawm hom alloy no feem ntau yog qis dua 90. Ntxiv rau kev xaiv cov carbide rau woodworking tej cuab yeej raws li cov yam ntxwv ntawm kev txiav ntoo, lub tuam txhab cuab yeej feem ntau kuj ua kev ntsuam xyuas raws li nws tus kheej tsim thiab ua technology, rooj tog Hoobkas khoom thiab kev khiav hauj lwm technology thiab lwm yam kev mob, thiab thaum kawg xaiv ib tug. nrog kev sib tw zoo tshaj plaws ntawm cemented carbide.
