Hauv kev tsim cov ntaub ntawv, cov vaj huam sib luag zoo nkauj, thiab cov txheej txheem sib xyaw ua ke, "pob zeb diamond saw hniav" yuav tsum tsis txhob raug kho raws li ib qho khoom lag luam. Cov pob zeb diamond ntu ntu cov hniav feem ntau yog siv rau pob zeb, ceramic, pob zeb, thiab lwm yam khoom siv tawv tawv. PCD pom cov hniav, ntawm qhov tod tes, feem ntau yog siv rau fiber ntau cement board, cement-raws li sab, gypsum board, composite panels, laminate, thiab lwm yam ntaub ntawv abrasive.
Rau cov neeg siv, txiav kev ua tau zoo tsis yog txiav txim siab yooj yim los ntawm seb cov hniav puas muaj pob zeb diamond. Dab tsi tseem ceeb tshaj yog qhov sib tw ntawm cov qauv pob zeb diamond, steel core stability, hniav geometry, kev sib khi txoj kev, thiab cov txheej txheem tswj kom zoo. Nakamura lub pob zeb diamond-chav pom hniav ntau yam yog tsim nyob ib ncig ntawm cov tswv yim zoo.
1. Nkag siab Ob Hom Pob Zeb Diamond-Class Blades
Ib hom pob zeb diamond ntu hniav feem ntau yog ua los ntawm cov tub ntxhais hlau thiab pob zeb diamond ntu. Cov pob zeb diamond hais hauv ntu yog tuav los ntawm ib daim ntawv cog lus hlau. Thaum lub sij hawm txiav, cov pob zeb diamond pom tau zom cov khoom tam sim ntawd. Raws li daim ntawv cog lus maj mam hnav, cov pob zeb diamond tshiab tau nthuav tawm, pab cov hniav tswj kev ua haujlwm.
PCD saw hniav siv cov qauv sib txawv. Nws feem ntau nta cov lus qhia polycrystalline pob zeb diamond, ua ke nrog cov hniav geometry thiab kev sib tsoo precision. Piv nrog rau cov qauv carbide hniav, PCD cov hniav yog zoo dua rau cov abrasive boards thiab composite cov ntaub ntawv, xws li fiber ntau cement board, gypsum -raws li panels, ntxhia- raws li panels, thiab engineered composite sheets.
Hauv Nakamura cov khoom lag luam tam sim no, lubPCD Fiber Cement Circular Saw Hniavyog tsim los rau cov ntaub ntawv abrasive xws li fiber ntau cement board thiab gypsum board. Nws lub hom phiaj tsis yog "txiav txhua yam," tab sis tswj kev txiav ruaj khov, ntev hnav tsis kam, thiab cov npoo huv si hauv kev xav tau ntawm daim ntaub ntawv.
2. Cov khoom sib txuam tseem ceeb tshaj qhov kev thov loj
Qhov kev ua tau zoo ntawm cov saw hniav pib nrog nws cov ntaub ntawv ua haujlwm zoo li cas.
Cov tub ntxhais hlau txhawb cov hniav thaum lub sij hawm siab -kev sib hloov ceev. Ib tug txhim khu kev qha tub ntxhais xav tau kom rigidity, flatness, thiab kuj rau deformation. Yog tias tsis muaj lub cev ruaj khov, txawm tias qhov kev txiav ntev ntev kuj tseem tuaj yeem ua rau muaj kev sib tsoo, kev kub ntxhov, lossis kev co.
Lub pob zeb diamond lossis PCD cov lus qhia ua haujlwm tseem ceeb. Rau cov ntaub ntawv abrasive, txiav ntug yuav tsum sib npaug hnav tsis kam thiab sharpness. Yog hais tias lub ntug yog ib qho nyuaj rau cov khoom, txiav yuav qeeb thiab kub. Yog tias nws hnav sai heev, lub cuab yeej lub neej yuav raug txo.
Cov hniav geometry thiab nti clearance kuj tseem ceeb. Fiber cement board, piv txwv li, yog abrasive heev thiab ua cov plua plav zoo thaum txiav. Cov hniav xav tau cov hniav kom haum, cov hniav zoo, thiab qhov chaw gullet. Nakamura cov7 1/4 Fiber Cement Hniavsiv cov -cov hniav- suav cov qauv PCD, ua rau nws tsim nyog rau fiber ntau cement txiav nrog tes tuav ncig saws thiab cov khoom siv ua haujlwm.
3. Cov txheej txheem tsim khoom txhais tau tias ruaj khov
Cov txheej txheem ntau rau pob zeb diamond-chav pom cov hniav muaj xws li sintering, vuam, brazing, electroplating, thiab PCD tip processing. Cov txheej txheem no tsis yog "zoo dua" lossis "phem dua." Txhua tus muaj nws qhov kev thov kom raug.
Sintering feem ntau yog siv rau pob zeb diamond ntu lossis ntu ntu ntu ntu. Los ntawm kev tsim cov hmoov hlau, pob zeb diamond particle xaiv, nias, thiab sintering, ntu tau txais kev hnav tsis kam thiab tswj tus kheej -txoj kev coj tus cwj pwm.
Laser vuam feem ntau yog siv los txuas cov pob zeb diamond ntu rau cov tub ntxhais hlau. Nws yog feem ntau xaiv thaum muaj zog txuas ntxiv thiab kev ruaj ntseg kub zoo dua. Lub hom phiaj yog kev sib txuas kev ntseeg siab ntawm ntu thiab lub cev hniav.
Brazing thiab nqus brazing yog siv rau qee yam khoom siv pob zeb diamond. Nqus brazing tuaj yeem nthuav tawm pob zeb diamond grits ntau dua thiab feem ntau siv hauv kev txiav - thiab - cov cuab yeej sib tsoo, tab sis nws yuav tsum tsis txhob piav raws li qhov tsim nyog rau txhua qhov hnyav - lub luag haujlwm txiav.
Rau PCD pom cov hniav, cov ntsiab lus tseem ceeb yog PCD cov lus qhia zoo, kev ruaj ntseg brazing, hniav geometry, thiab txiav - ntug kev sib tsoo raug. Rau me me -inch abrasive cov ntaub ntawv txiav, lub10T PCD Txiav Hniavtuaj yeem siv rau cov cement-raws li kev sib tw, ultra- cov khoom siv hluavtaws fiber ntau sab nrauv, thiab cov ntaub ntawv zoo sib xws uas cov npoo ruaj khov thiab hnav tsis kam.
4. Kev Tswj Xyuas Zoo yog qhov tseem ceeb tshaj li cov lus hais
Rau kev lag luam saw hniav, txhim khu kev qha zoo tsis yog kev lag luam nqe lus. Nws yog ib txheej txheem rov ua dua.
Ntawm cov khoom siv raw khoom, steel phaj zoo, lub cev hardness, thiab sib xws ntawm PCD lossis pob zeb diamond tswv yim yuav tsum tau tswj. Thaum lub sij hawm ua, cov hniav flatness, axial runout, radial runout, hniav lub kaum sab xis, brazing los yog vuam zog, thiab tshuav nyiaj li cas yuav cuam tshuam rau kev txiav.
Cov hniav tiav kuj xav tau kev txiav txim siab nrog cov ntaub ntawv tiag. Thaum txiav cov fiber ntau cement board, piv txwv li, cov neeg siv yuav tsum xyuas cov npoo chipping, plua plav tawm, txiav tsis kam, hnav tsis kam, thiab kub tsim. Cov hniav tsuas yog tsim nyog rau kev txiav txim rov qab thaum cov ntsuas no nyob ruaj khov.
5. Cov khoom sib txawv yuav tsum tau xaiv cov hniav sib txawv
Pob zeb, ceramic, pob zeb, fiber ntau cement, thiab cov ntaub ntawv sib xyaw tej zaum yuav nyuaj rau kev txiav, tab sis lawv tsis xav tau cov qauv hniav tib yam.
Pob zeb thiab pob zeb txiav feem ntau yog nyob ntawm pob zeb diamond ntu kev tsim, ntub lossis qhuav txiav, lub zog tshuab, thiab ntu txias. Ceramic thiab pobzeb txiav tsom ntau dua ntawm kev tsim cov npoo txuas ntxiv, ntug chipping tswj, thiab cua txias. Fiber cement board, gypsum board, mineral-raws li panels, thiab tej yam boards feem ntau zoo sib xws nrog PCD pom hniav, tshwj xeeb tshaj yog thaum cov neeg siv xav tau lub neej ntev thiab tsawg dua cov hniav hloov.
Yog vim li cas cov hniav xaiv yuav tsum tsis txhob nres ntawm lo lus "pob zeb diamond." Cov neeg siv yuav tsum xav txog cov khoom siv, tshuab fais fab, txiav txoj kev, ntug yuav tsum tau, thiab txiav zaus. Rau cov chaw tsim khoom thiab cov neeg cog lus, cov hniav zoo tshaj plaws tsis yog ib qho uas muaj qhov tshwj xeeb tshaj plaws, tab sis yog ib qho uas sib npaug ruaj khov txiav, cuab yeej lub neej, thiab tag nrho cov nqi txiav.
Xaus
Txoj kev loj hlob ntawm saw hniav technology tsis yog tsuas yog ua rau txiav ntug nyuaj. Nws yog hais txog kev ua cov hniav kom haum rau cov khoom siv thiab kev ua haujlwm.
Tus nqi ntawm Nakamura pob zeb diamond-chav pom cov hniav yuav tsum tsis txhob txwv rau cov lus dav xws li "ntse" lossis "huv." Nws yuav tsum nkag siab los ntawm cov ntawv thov tiag tiag: cov khoom siv twg raug txiav, lub tshuab siv dab tsi, qhov ntug zoo li cas, thiab cov nqi siv nyiaj dab tsi uas tus neeg siv xav tau.
Thaum cov khoom siv, txheej txheem, thiab daim ntawv thov raug sib raug zoo, lub saw saw tuaj yeem xa tus nqi ruaj khov hauv kev txiav cov khoom siv.
