Mitundu ya Odula a CBN

Odula a CBN amapangidwa ndi cubic boron nitrite. Iwo ali ndi makhalidwe ambiri, monga:

1.Kuuma kwa cubic boron nitrite cutter ndikocheperako kuposa diamondi. Ndipo cubic boron nitrite imakhala ndi kukana kovala bwino ndipo imatha kukhala ndi moyo wautali wogwira ntchito;

Odula a 2.CBN ali ndi kukana kutentha kwakukulu, ndipo amatha kusungabe zinthu zake zokhazikika zakuthupi pansi pa kutentha kwakukulu, zomwe zimapereka chikhalidwe cha liwiro lapamwamba ndi kudula kutentha kwakukulu;

Zodula za 3.CBN ndizokhazikika pamankhwala, ndipo zimatha kuthana ndi mpweya. Iwo akhoza kusunga katundu wake khola mankhwala ngakhale kumvetsa 1000 ℃;

4.Kutentha kwabwino kwa zida za CBN kungapangitse kutentha kuchokera ku nsonga ya chida kufalikira mofulumira, zomwe zimapindulitsa kuwongolera kulondola kwa makina a workpiece.

5.Chigawo chochepa cha mkangano wa chida cha CBN chimapangitsa kuti tsambalo likhale ndi mphamvu zotsutsana ndi zomangira, zomwe zimathandiza kuti pakhale malo okonzedwa bwino.

Odula a CBN ali ndi mitundu itatu yayikulu, ndipo ndi chida cholimba cha CBN, zoyikapo za PCBN, ndi zoyikapo za CBN.

(1) Chida cholimba cha CBN

Pokonza zida zachitsulo zosakwana 10% ferrite, zida zolimba za CBN zodulira zimapereka kukana kwabwino komanso kukana kwamphamvu. Itha kugwiritsidwa ntchito kumalizitsa komanso kupanga makina ovuta okhala ndi malire ambiri, omwe amawonjezera mphamvu zamakina ndikuchepetsa mtengo wamakina. Chida chodulira chamtunduwu chidzakhala chodziwika kwambiri ndi makasitomala pomwe kuuma kwamphamvu kwambiri kumachulukira, ndipo gawo la msika lidzakhalanso ndi kukula kwakukulu m'zaka zikubwerazi.

(2) PCBN Insert

Zinthu za CBN zimawotcherera pamphepete mwa tsamba, ndipo chida chodulira cha PCBN chiyenera kugwiritsidwa ntchito ndi gawo lapansi lopangidwa bwino ndi simenti ya carbide. Imatha kukwaniritsa kusalala bwino komanso kulondola kwazithunzi ndipo imakhala ndi kukana kwabwino. Amagwiritsidwa ntchito kwambiri pomaliza njira ndi kuuma kwa HRC45 ndi malire ang'onoang'ono.

(3) Brazing CBN Insert

Mbali imodzi ya Brazing CBN Insert ili ndi mbali zingapo zodula chifukwa chapamwamba kwambiri, yomwe imayikidwa pagawo la carbide. Chida chodulira chamtunduwu chikhoza kupangidwa m'mbali zingapo, zomwe zimachepetsa kwambiri mtengo wopangira ndipo zimakhala zotsika mtengo kuposa zida zodulira. Koma gawo lomaliza ndilomwe limagwiritsidwa ntchito kwambiri.

Ngati muli ndi chidwi ndi zinthu za tungsten carbide ndipo mukufuna zambiri ndi zambiri, mutha KULUMIKIZANA NAFE pa lamya kapena makalata kumanzere, kapena TITUMIZANI MAIME pansi pa tsamba.
