Chitsulo champhamvu kwambiri chimawonjezedwa ndi zinthu zosiyanasiyana za alloying muzitsulo.Pambuyo pa chithandizo cha kutentha, zinthu zopangira ma alloying zimalimbitsa njira yolimba, ndipo mawonekedwe a metallographic nthawi zambiri amakhala martensite.Ili ndi mphamvu yayikulu komanso kuuma kwakukulu, ndipo kulimba kwake kumakhalanso kopitilira zitsulo 45.Mphamvu yodula panthawi yodula idzakhala 25% -80% kuposa mphamvu yodula ya 45, kutentha kwapamwamba kwambiri, ndipo kusweka kwa chip kumakhala kovuta.Kotero, pakupanga kwenikweni, kodi zitsulo zamphamvu kwambiri zimadula bwanji?
1. Chida
Pakudula movutikira komanso kosokoneza, chidacho chimafunikira kuti chikhale ndi kukana kugwedezeka kwamafuta.Kuphatikiza pa zida za diamondi, zida zamitundu yonse zimatha kudulidwa.Posankha zida za zida, ziyenera kusankhidwa molingana ndi mikhalidwe yodulira.
A. Chitsulo chothamanga kwambiri
Kusankhidwa kwazitsulo zothamanga kwambiri zopangira zitsulo zamphamvu kwambiri komanso zowonjezereka kwambiri ziyenera kukhazikitsidwa ndi katundu, mawonekedwe, njira yopangira ndi kukhazikika kwa ndondomekoyi, ndikuganizira mozama kukana kutentha, kuvala kukana ndi kulimba kwa chida.Pamene ndondomekoyi imakhala yolimba kwambiri ndipo mawonekedwe a chida ndi osavuta, tungsten-molybdenum-based, high-carbon low-vanadium-containing aluminium high-speed steel kapena tungsten-molybdenum-based high-carbon low-vanadium high-cobalt high- liwiro zitsulo angagwiritsidwe ntchito;pansi pazigawo zodula, tungsten-molybdenum ingagwiritsidwe ntchito.Chitsulo chokwera kwambiri cha vanadium.
B. zitsulo ufa mkulu liwiro zitsulo ndi malata TACHIMATA mkulu liwiro zitsulo
Ufa zitsulo mkulu-liwiro zitsulo ndi ufa mkulu-liwiro kuti mwachindunji mbamuikha pa kutentha ndi kuthamanga, ndiyeno anapeka mu chofunika chida mawonekedwe.Imakhala yakuthwa pambuyo pokonza ndipo imakhala ndi kuuma kwakukulu komanso kukana kwambiri kuvala.Ndizoyenera zitsulo zamphamvu kwambiri komanso zapamwamba.Kudula kwachitsulo champhamvu kwambiri.
C. Simenti ya carbide
Cemented carbide ndiye chida chachikulu chodulira zitsulo zamphamvu kwambiri komanso zolimba kwambiri.Nthawi zambiri, ma aloyi olimba olimba kwambiri kapena ma alloys olimba olimba ayenera kusankhidwa.
D. Mipeni ya ceramic
Kuuma kwake ndi kukana kutentha ndikwambiri kuposa ma aloyi olimba, kulola kuthamanga kwachangu 1-2 kuposa ma carbides opangidwa ndi simenti.Podula chitsulo champhamvu kwambiri komanso chitsulo champhamvu kwambiri, zida za ceramic zimagwiritsidwa ntchito makamaka pazitsulo zogwirira ntchito komanso kukonza bwino.
2. Kudula ndalama
Liwiro lodula la kutembenuza chitsulo champhamvu kwambiri kuyenera kukhala 50% -70% kutsika kuposa kuthamanga kwachitsulo wamba.Kukwera kwamphamvu ndi kuuma kwa zida zogwirira ntchito, kutsika kwachangu kumayenera kukhala.Kudula liwiro lachitsulo champhamvu kwambiri chodula chitsulo champhamvu kwambiri ndi (3-10) m/mphindi, chida cha carbide (10-60) m/mphindi, chida cha ceramic ndi (20-80) m/mphindi, chida cha CBN ndi (40) -220) m/mphindi.Kuzama kwa kudula ndi chakudya ndizofanana ndi chitsulo chotembenuza.
3. Chip kuswa njira
Chifukwa cha mphamvu yamphamvu yachitsulo champhamvu kwambiri, sikophweka kuthyola chip panthawi yotembenuka, zomwe zimabweretsa zovuta kwambiri pakuyenda bwino kwa kutembenuka.M'pofunika kumvetsera kwambiri izi pokonza.
