CBN

Lub polycrystalline cubic boron nitride (CBN) inserts muab ib qho txiaj ntsig zoo rau cov cuab yeej pob zeb diamond. Txawm hais tias CBN qhov tshwj xeeb toughness / hardness tseem tsawg dua cov khoom siv pob zeb diamond, nws tseem nyob ruaj khov ntawm qhov kub txog li 1400 ° C, thaum pob zeb diamond pib decompose ntawm 800 ° C. Tsis tas li ntawd, nws cov tshuaj tiv thaiv rau cov ntaub ntawv ferrous zoo dua li ntawm PCD.
Qhov no ua rau CBN ntxig cov kev daws teeb meem (dhau pob zeb diamond) hauv ntau daim ntawv thov, tshwj xeeb tshaj yog cov uas koom nrog kev ua haujlwm ntawm hardened steels (45-72 HRC) ntawm txhua yam: Case hardened steel, cuab yeej steel, cua sov kho steel, thiab lwm yam. Lawv sib xws. nrog cov cuab yeej txheem tuav los ntawm lwm tus, ua manufacturers.
CCGW Inserts
Ib kab ntawm inserts nrog 80 ° txiav kaum sab xis, thiab ob lub tswv yim txiav. Cov ntawv ntxig no muaj lub kaum sab xis nruab nrab, thiab lub kaum sab xis ntawm 7 °.
Nta:

• Wiper geometry versions muaj

Nco tseg:

• CCGW 060201 thiab CCGW 09T301 inserts tsuas yog muaj nyob rau hauv qib CH25 thiab CK65
• CCGW 09T302-W wiper insert tsuas yog muaj nyob rau hauv qib CP25 / CP45 / CK65 / CK85

CBN: hu ua cubic boron nitride.
Kev ua tau zoo: ua cov ntaub ntawv nyuaj heev, nrog rau siab hardness, tshuaj inertness thiab kub kub.
Nws muaj qhov zoo thermal stability thiab hnav tsis kam. Qhov hnav tsis kam yog 50 npaug ntawm cov cemented carbide hniav, 30 npaug ntawm cov cemented carbide hniav, thiab 25 npaug ntawm cov hniav ceramic. Feem ntau yog siv los txiav hardened steel, chilled cam khwb cia hlau thiab nto thermal txau cov ntaub ntawv.
