② Iyo cubic boron nitride chishandiso, modhi FD, inokwanisa kugadzira akasiyana simbi dzakaomeswa uye kupfapfaidza.akashandura zvikamupakucheka kukurumidza kusvika ku100 m / min, kuwana hutsinye hwepamusoro hweRa 0.80 kusvika 0.20 μm. Pamusoro pezvo, iyo composite cubic boron nitride chishandiso, DCS-F, iyo inogadzirwa neHurumende-inomiririra Capital Machinery Factory uye Guizhou Sixth Grinding Wheel Factory, inoratidza kuita kwakafanana.
Zvisinei, kushanda kwekugadzirisa kwezvishandiso izvi kwakaderera kune kweiyo simende carbide. Nepo kusimba kwecubic boron nitride maturusi akadzikira pane ecemented carbide, anopa hudzamu hudiki hwekubatanidzwa uye anodhura zvakanyanya. Uyezve, musoro wekushandisa unogona kukuvara nyore kana ukashandiswa zvisina kunaka.
⑨ Ceramic maturusi, kucheka kumhanya ndeye 40-60m/min, isina simba simba.
Zvishandiso zviri pamusoro zvine maitiro azvo mukutenderedza zvikamu zvakadzimwa uye zvinofanirwa kusarudzwa zvinoenderana nemamiriro chaiwo ekushandura zvinhu zvakasiyana uye kuoma kwakasiyana.
(3) Mhando dzesimbi dzakadzimwa zvikamu zvezvinhu zvakasiyana-siyana uye kusarudzwa kwebasa rekushandisa
Zvikamu zvesimbi zvakadzimwa zvezvinhu zvakasiyana zvine zvinodiwa zvakasiyana zvachose zvekushandisa kwechishandiso pakuoma kwakafanana, izvo zvinogona kukamurwa kuita zvikamu zvitatu zvinotevera;
① Yakakwira alloy simbi inoreva simbi yechishandiso uye simbi inofa (kunyanya dzakasiyana-siyana simbi inomhanya) ine yakazara alloying element yezvinhu zvinodarika gumi%.
② Alloy simbi inoreva simbi yekushandisa uye inofa simbi ine alloying chinhu chiri mukati me2-9%, senge 9SiCr, CrWMn, uye yakakwirira-yakasimba alloy simbi yekugadzira.
③ Carbon simbi: inosanganisira akasiyana kabhoni maturusi mashizha esimbi uye carburizing simbi seT8, T10, 15 simbi, kana makumi maviri simbi carburizing simbi, nezvimwe.
Kune kabhoni simbi, iyo microstructure mushure mekudzima ine tempered martensite uye shoma shoma yecarbide, zvichikonzera kuomarara kweHV800-1000. Izvi zvakaderera zvakanyanya pane kuomarara kwetungsten carbide (WC), titanium carbide (TiC) mune simende carbide, uye A12D3 mumaturusi eceramic. Pamusoro pezvo, kuomarara kwekabhoni simbi kushoma pane kwemartensite isina alloying element, kazhinji isingadarike 200°C.
Sezvo zviri mukati meiyo alloying zvinhu musimbi zvichiwedzera, iyo carbide yemukati muiyo microstructure mushure mekudzima uye kupisa inokwira zvakare, zvichitungamira kune yakanyanya kuomarara akasiyana e carbides. Semuenzaniso, musimbi inomhanya-mhanya, iyo carbide yemukati inogona kusvika 10-15% (nehuwandu) mushure mekudzima uye kupisa, kusanganisira mhando dzakadai seMC, M2C, M6, M3, uye 2C. Pakati peizvi, vanadium carbide (VC) ine kuomarara kwakanyanya kudarika iyo yechikamu chakaoma mune zvakajairika zvishandiso zvekushandisa.
Uyezve, kuvepo kweakawanda alloying element kunowedzera kuomarara kwekupisa kwemartensite, zvichiita kuti isvike kusvika 600 ° C. Nekuda kweizvozvo, machinability emasimbi akaomeswa ane macrohardness akafanana anogona kusiyana zvakanyanya. Usati washandura simbi dzakaomeswa zvikamu, zvakakosha kuti uone chikamu chazvo, unzwisise maitiro avo, uye usarudze akakodzera maturusi emidziyo, kucheka maparamita, uye chishandiso geometry kuti upedze kutendeuka nenzira kwayo.
Kana iwe uchida kuziva zvakawanda kana kubvunza, ndapota inzwa wakasununguka kubatainfo@anebon.com.
