Polycrystalline Diamond (PCD) Zvishandiso zvekucheka

Kuvandudzwa kwePCD yekucheka maturusi

Dhaimondi sechinhu chakanyanya kuoma chishandiso chinoshandiswa mukucheka kugadzira, iyo ine nhoroondo yemazana emakore. Mukugadzira maturusi ekucheka kubva pakupera kwezana ramakore rechi 19 kusvika pakati pezana ramakore rechi20, zvishandiso zvematurusi zvainyanya kumiririrwa nesimbi inomhanya kwazvo. Muna 1927, Germany yakatanga kugadzira carbide tool zvinhu uye yakawana kushandiswa zvakanyanya.

Mumakore ekuma1950, Sweden neUnited States dzakatevedzana dzakagadzira maturusi ekucheka madhaimani, nokudaro kupinda munguva inomiririrwa nezvinhu zvakaomarara. Mumakore ekuma1970, polycrystalline diamond (PCD) yakagadziridzwa ichishandisa yakakwira-kumanikidza synthesis tekinoroji, iyo yakawedzera chiyero chekushandisa kwematurusi edhaimondi kune avhiyesheni, aerospace, mota, zvemagetsi, dombo, uye mamwe minda.

Kuita maitiro ePCD zvishandiso

Maturusi ekucheka madhaimani ane hunhu hwekuomarara kwepamusoro, kusimba kwakasimba kwesimba, yakanaka yekupisa conductivity, uye kupfeka kuramba, izvo zvinogona kuwana yakakwira machining kurongeka uye kushanda zvakanaka mukucheka-kumhanya kukuru.

Kushandiswa kwePCD zvishandiso

Kubva dhaimondi rekutanga repolycrystalline rakagadzirwa muSweden muna 1953, tsvakiridzo yekucheka mashandiro ePCD maturusi yakawana mhedzisiro yakawanda, uye chiyero chekushandisa uye kushandiswa kwePCD zvishandiso zvakakurumidza kuwedzera.

Parizvino, vagadziri vepasi rose vane mukurumbira madhaimondi epolycrystalline vanonyanya kusanganisira De Beers Company yekuUnited Kingdom, GE Company yekuUnited States, Sumitomo Electric Co., Ltd. yekuJapan, nezvimwewo. Zvinonzi muchikamu chekutanga cha1995. Kugadzirwa kwechishandiso chekuJapan kwePCD chete kwakasvika zvidimbu zve107,000. Iyo chiyero chekushandisa chePCD maturusi akawedzera kubva pakutanga kutendeuka maitiro kuenda kune yekuchera nekugaya. Ongororo pamusoro pematurusi akaomarara akaitwa nesangano reJapan yakaratidza kuti pfungwa huru dzekuti vanhu vasarudze maturusi ePCD dzinobva pane zvakanakira kurongeka kwepamusoro, kurongeka kwedimensional, uye hupenyu hwematurusi mushure mekugadzirisa nePCD zvishandiso. Iyo synthesis tekinoroji yemadhaimondi anoumbwa mapepa akagadzirwa zvakare zvakanyanya.

ZZBETTER PCD zvishandiso

ZZBETTER PCD maturusi anosanganisira akasiyana mamakisi uye dimensional masisitimu. Rudzi rwechigadzirwa runosanganisira mamakisi ane avhareji saizi yezviyo kubva pa5 kusvika 25 microns uye 62mm inogona kushandiswa dhayamita. Zvigadzirwa zvinowanikwa semadhisiki akazara kana matipi ekucheka mukusiyana kwese uye PCD layer ukobvu.

Mabhenefiti ekushandisa ZZBETTER PCD inopa yakavimbika uye inowirirana kuita pamutengo wemakwikwi. Inonatsiridza kugadzirwa nyore, inogonesa mareti epamusoro ekudyisa, uye inopa yakagadziridzwa kupfeka kuramba kweakasiyana workpiece zvinhu. Iyo ine mamakisi akawanda ane tungsten carbide yekuwedzera kune PCD layer, iyo inogonesa vagadziri vezvishandiso kuburitsa magetsi muchina (EDM) uye / kana magetsi anoburitsa grinds (EDG) nekukurumidza. Huwandu hwayo hwakawanda hwemagiredhi inobvumira kuchinjika mukusarudza iyo chaiyo zvinhu kune chero machining application

For Woodworking

Wedzera mareti ekudya uye uvandudze hupenyu hwechishandiso mukugadzira matanda senge yepakati-density fiberboard (MDF), melamine, laminates, uye particleboard.

Kune Heavy Industry

Kurisa kupfeka kuramba uye kuderedza nguva yekudzikira mumatombo ekugadzira, kongiri, simende bhodhi, uye mamwe abrasive workpieces.

Mamwe Maapplication

Deredza maturusi ezvishandiso uye uwedzere kuenderana kweyakaoma-kune-muchina zvinhu, senge kabhoni kompositi, acrylics, girazi, uye zvimwe zvakawanda zvisina ferrous uye zvisiri zvesimbi zvinhu.

Zvimiro zvichienzaniswa ne tungsten carbide zvishandiso:

1, Kuoma kwePCD kunosvika makumi masere kusvika zana nemakumi maviri nguva yetungsten carbide.

2. Thermal conductivity yePCD ndeye 1.5 kusvika 9 nguva iyo ye tungsten carbide.

3. Upenyu hwematurusi ePCD hunogona kudarika carbide cutting tool life 50 kusvika ku100 times.

Zvimiro zvichienzaniswa nemidziyo yedhaimani chaiyo:

1, PCD inoshingirira kupfuura madhaimondi echisikigo nekuda kweiyo isina kurongeka yekumisikidzwa kwezvikamu zvedhaimondi uye inotsigirwa necarbide substrate.

2, PCD inogara ichipfeka nekuda kweiyo yakazara dhizaini sisitimu yemhando yekudzora kusimba, dhaimondi rechisikigo ikiristaro imwe chete muzvisikwa uye ine zviyo zvakapfava uye zvakaoma kana zvaitwa mukushandisa. Hazvizoshandiswi zvakanaka nezviyo zvinyoro.

3, PCD yakachipa uye ine maumbirwo akasiyana uye saizi yekusarudza kubva kune yekushandisa, dhaimondi rechisikigo ndiro rinogumira pamapoinzi aya.

PCD yekucheka maturusi anoshandiswa zvakanyanya muindastiri nekuda kwehutano hwavo hwakanaka hwekugadzirisa uye kugadzirisa hupfumi. Inoratidza mabhenefiti ayo mamwe maturusi haakwanise kuenderana neNon-metallic zvinhu, asiri-ferrous simbi uye ayo alloy zvinhu, uye kumwe kuchekwa kwekucheka. Kudzika kwekutsvagisa kwedzidziso paPCD yekucheka maturusi anosimudzira chinzvimbo chePCD zvishandiso mumunda weakanyanya-akaoma maturusi. Iyo PCD ichawedzera kukosha, uye chiyero chekushandisa kwayo chichawedzerwawo.
