PCD txheej txheem tsim khoom

Nrog rau kev txhim kho sai ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no, cov cuab yeej ua los ntawm cov khoom siv superhard xws li pob zeb diamond aspolycrystalline (PCD) thiab polycrystalline cubic boron nitride (PCBN) tau dhau los ua ntau thiab ntau dua, thiab lawv cov kev ua tau zoo kuj tau tsim thiab txhim kho tas li. Lub abrasive grain loj ntawm cov hniav yog los ntawm kaum ntawm microns mus rau ob peb microns mus rau nanometers; cov ntsiab lus ntawm pob zeb diamond thiab cubic boron nitride muab faib ua cov ntsiab lus qis, nruab nrab cov ntsiab lus thiab cov ntsiab lus siab;

Tus neeg sawv cev sib txuas muaj ob qho tib si hlau, tsis yog hlau thiab cov khoom sib xyaw; lub thickness ntawm PCD txheej yog li ntawm millimeter mus rau micron theem; kev sib xyaw ntawm PCD txheej thiab cemented carbide substrate muaj tiaj tiaj thiab corrugated nto; PCD txheej muaj cov yam ntxwv sib txawv xws li hnav tsis kam, siab toughness thiab siab kub tsis kam. Tam sim no, daim ntawv thov ntau yam ntawm PCD thiab PCBN cov cuab yeej tau nthuav dav rau kev lag luam xws li tsheb, aerospace, precision machinery, khoom siv hauv tsev, ntoo, hluav taws xob thiab hluav taws xob, thiab lwm yam, siv los ua cov cuab yeej tig, cov cuab yeej tho txawv, milling cutters thiab laum. khoom, reamers, countersinks, saw hniav, Carving riam, rab chais, thiab lwm yam.

Txawm hais tias kev txhim kho sai ntawm PCD thiab PCBN cov cuab yeej, qhov nyuaj ntawm cov cuab yeej sharpening vim lawv cov hardness siab ib txwm plagued feem ntau cov neeg siv, thiab cov rov sib tsoo ntawm cov hniav yog tsuas yog ua los ntawm cov thawj cov cuab yeej manufacturers. Tsis tsuas yog cov cuab yeej tus nqi siab thiab lub sij hawm xa khoom ntev, tab sis nws kuj occupies lub tuam txhab ua hauj lwm peev. Yog li ntawd, nws yog ib qho tsim nyog yuav tsum kawm txog kev sib tsoo cov yam ntxwv ntawm PCD thiab cov cuab yeej ntse ntawm PCD cov cuab yeej.

PCD txheej txheem tsim khoom

Cov txheej txheem ntawm PCD txiav cov cuab yeej feem ntau suav nrog polishing, txiav, kho, sharpening, tshuaj xyuas zoo thiab lwm yam. Txoj kab uas hla ntawm PCD cov khoom siv superhard feem ntau yog 1/2, 1, 2, 3, 4 ntiv tes, qhov saum npoo feem ntau ntxhib (Ra2 ~ 10μm), tsis tuaj yeem siv ncaj qha los ua cov cuab yeej, nws xav tau yuav tsum polished kom tiav daim iav nto (Ra tsawg dua los yog sib npaug rau 0.01μm), thiab tom qab ntawd ua tiav rau hauv cov hniav nrog qee cov duab geometric thiab qhov ntau thiab tsawg los ntawm laser txiav lossis xaim hluav taws xob txiav txiav, thiab tom qab ntawd ntxiv cov tshuab thiab tshuaj kho qhov chaw ntawm lub cov hniav thiab cov substrate yuav tsum tau tsau, thiab ces nyiaj-raws li brazing cov hniav Nws yog tsau rau ntawm substrate thiab thaum kawg sharpened los ntawm ib tug pob zeb diamond log.

Ib qho ntawm cov yuam sij rau PCD txiav cov cuab yeej tsim tshuab yog qhov zoo ntawm kev txiav ntug. Qhov tsis muaj qhov zoo tshaj plaws sharpening technology thiab technology rau high-zoo cutter lub taub hau cov ntaub ntawv yuav ua rau cov khoom pov tseg. Kev siv cov cuab yeej zoo sharpening yuav txhim kho cov khoom zoo ntawm cov cuab yeej thiab txo tus nqi ntawm kev siv cov cuab yeej.
