CBN vs. PCD: Hondo yeSuperhard Kucheka Zvishandiso - Kunyura Kwakadzika muKugadzira uye Kuita.
CBN (Cubic Boron Nitride) CNC Kucheka Zvishandiso
CBN, kana Cubic Boron Nitride, chinhu chekugadzira chinozivikanwa nekuoma kwayo kwakanyanya uye kusimba. Iyo yechipiri chete kune dhaimani maererano nekuoma, izvo zvinoita kuti ive chinhu chakakodzera chekucheka maturusi anoshandiswa mune yakakwirira-kuita machining. CBN yekucheka maturusi anowanzo shandiswa kugadzira simbi dzakaomeswa, simbi dzakakandwa, uye zvimwe zvakakwirira-simba zvinhu zvinonetsa kugadzirisa neyakajairwa kucheka maturusi.
Kugadzira Maitiro eCBN Zvishandiso:
Kugadzirwa kweCBN yekucheka maturusi kazhinji kunosanganisira synthesis yeboron nitride (BN) pasi pekumanikidzwa kwakanyanya uye tembiricha. Iyo nzira inotanga ne boron powder uye nitrogen gasi, iyo inotarisana nemamiriro ezvinhu akaipisisa (pamusoro pe1500 ° C) kuti iite cubic boron nitride (c-BN) makristasi. Aya makristasi anobva asanganiswa neye matrix zvinhu, kazhinji cobalt binder, kugadzira yekuchekesa yekuisa kana chishandiso. Musanganiswa uyu unopa chishandiso cheCBN nekuoma kwayo kunoshamisa uye kuramba kupfeka.
CBN inoisa inogona kugadzirwa mune akasiyana maumbirwo uye saizi, zvichienderana neakananga machining zvinodiwa. Chishandiso chekupedzisira chinowanzo sinter, pasi, uye chakaputirwa kuti chiwedzere kuita kwayo uye kupera kwepamusoro. Iko kugona kwechishandiso kuchengetedza yakapinza yekucheka mipendero pakupisa kwakanyanya kunoita kuti ive sarudzo yakanaka kune inorema-basa rekushandisa mumaindasitiri akadai seaerospace, mota, uye kugadzira maturusi.
PCD (Polycrystalline Diamond) CNC Kucheka Zvishandiso
PCD, kana Polycrystalline Diamond, chinhu chinogadzirwa nekusunganidza pamwe chete makristasi edhaimani pasi pekumanikidzwa kwakanyanya uye tembiricha, zvichikonzera yakasimba, yakasimba yekucheka chishandiso. Zvishandiso zvePCD zvinozivikanwa nekusapfeka kwavo kusamira, kunyanya kana vachigadzira simbi dzisina-ferrous sealuminium, mhangura, nendarira, pamwe nezvinhu zvakaumbwa.
Kugadzira Maitiro ePCD Zvishandiso:
Kugadzirwa kwePCD zvishandiso kunotanga nekusikwa kwehupfu hwedhaimondi yakanaka, iyo inosanganiswa nesimbi binder, kazhinji cobalt kana mamwe mapfudze esimbi. Musanganiswa uyu unobva waiswa kune-high-temperature, high-pressure process inozivikanwa se "sintering" mumuchina wakakosha. Munguva iyi, makristasi edhaimani anobatana pamwechete, achigadzira dense, polycrystalline chimiro.
Zvishandiso zvePCD zvinowanzogadzirwa mumhando mbiri huru: monolithic uye brazed. Munzira ye monolithic, chimbo chacho chose chinogadzirwa kubva kuPCD, asi mune yakasvibiswa nzira, nhete yePCD inosungirirwa kune carbide substrate. Mushure mekunyunguduka, maturusi ePCD anogadzikwa uye akakwenenzverwa kusvika pachiyero chaihwo, kuve nechokwadi chekucheka mipendero yakapinza uye kupera kwepamusoro. Vanogona kuwedzererwa kurapwa nejasi kuti vawedzere kuramba kwavo kupfeka uye oxidation, izvo zvinogona kuvandudza mashandiro avo mune chaiwo maapplication.
Maturusi ePCD anowanzo shandiswa pakuita mabasa ekucheka akanyanya-chaiyo uye anonyanya kubatsira pakugadzira zvinhu zvinokonzeresa kupfeka kumidziyo yechinyakare. Nekuda kwekuomarara kwavo kwakasarudzika uye kushomeka kwemagetsi, vanopa mashandiro akatanhamara mukupedzisa uye nekumhanya-mhanya machining mashandiro.
Kuenzanisa pakati peCBN nePCD CNC Kucheka Zvishandiso
| Property | CBN (Cubic Boron Nitride) | PCD (Polycrystalline Diamond) |
|---|---|---|
| Kuumbwa Kwezvinhu | Yakaoma, yakagadzirwa boron nitride | Synthetic diamond zvidimbu zvakasungwa pasi pekumanikidzwa kukuru |
| Kuoma | Yakakwirira kwazvo, yechipiri chete kune diamond | Yakanyanya kukwirira, iyo yakaoma kwazvo inozivikanwa |
| Applications | Simbi dzakaomeswa, simbi dzakakandwa, alloys ekupisa kwepamusoro | Non-ferrous simbi, composites, aruminiyamu, mhangura, nezvimwe. |
| Pfeka Resistance | Yakanakisa, kunyanya neyakaoma, abrasive zvinhu | Yakanakisa, kunyanya kune yakapfava, isiri-ferrous simbi |
| Thermal Kugadzikana | Yakakwirira kwazvo, inobata kupisa kwakanyanya zvakanaka | Pakati nepakati, inonzwa kune tembiricha yakakwira |
| Tool Life | Hupenyu hurefu hwematurusi mukukasharara uye inorema-basa machining | Upenyu hurefu hwematurusi, kunyanya mukupedzisa mashandiro |
| Kucheka Speed | Yakanakira kucheka kunorema uye kumhanya kuri pakati nepakati | High kucheka kumhanya kwechiedza uye chepakati chekucheka |
| Mutengo | Kazhinji yakaderera pane PCD | Yakakwirira nekuda kwemaitiro ekugadzira uye zvinhu |
| Typical Industries | Aerospace, mota, kufa uye mold, maindasitiri esimbi | Motokari, aerospace, zvemagetsi, uye mapurasitiki |
| Surface Finish | Kunyatsonaka uye kupedzisa kwepamusoro muzvinhu zvakaoma | Yakanakisa pamusoro pekupedzisira mune zvisiri-ferrous zvinhu |
Misiyano Yakakosha:
Kuenderana kwezvinhu:
CBN inonyanya kukodzera zvinhu zvakaoma uye zvinoputika sesimbi dzakaomeswa uye simbi yakakandwa.
PCD yakanakira zvinhu zvakapfava sealuminium, mhangura, uye macomposites, ayo anowanzo pfeka pasi maturusi echinyakare nekukurumidza.
Performance at High Temperature:
Zvishandiso zveCBN zvinogona kumira tembiricha yepamusoro pasina kushatisa, zvichiita kuti zvive zvakanyanya kushanda kune yakakwirira-simba uye yakanyanya-kupisa machining mamiriro.
Zvishandiso zvePCD, nepo zvakaoma, hazvishiviriri zvakanyanya tembiricha uye zvinogona kurasikirwa nemucheto pasi pemamiriro akadaro.
Kufunga Kwemari:
Maturusi eCBN anowanzo kuve anodhura kupfuura maturusi ePCD, sezvo PCD inoda maitiro akaomarara ekugadzira uye iyo mbishi pachayo inodhura.
Surface Finish uye Precision:
Zvishandiso zvePCD zvakanyanyokodzera kuwana yekupedzisira-yakanaka pamusoro pekupedzisira, kunyanya mune zvisiri-ferrous zvinhu.
Zvishandiso zveCBN, nepo zviri izvo, zvinokunda zvakanyanya mukusimba uye kucheka kusimba pane kuwana iyo yepamusoro yepamusoro kupedzisa mune zvakapfava zvinhu.
Ose ari maviri CBN uye PCD CNC yekucheka maturusi anopa yakasarudzika mashandiro, asi anoitira akasiyana machining zvinodiwa. Zvishandiso zveCBN zvakanakira kuomarara, midziyo yakaoma uye yakakwirira-tembiricha maapplication, nepo PCD maturusi anopenya kana uchishanda nesimbi dzakapfava uye zvakaumbwa zvinhu, zvichipa hupenyu hurefu hwematurusi uye kuita kwakanakisa kwekucheka. Kusarudza pakati pezviviri zvinoenderana nechinhu chaicho chiri kugadzirwa, hupenyu hwematurusi hunodiwa, uye nharaunda yekugadzira.
