Mabasic coatings marudzi e end mill

Iyo carbide end mill inozivikanwawo secemented carbide end mill. Kuoma kwechishandiso pachacho kunowanzo kuve pakati peHRA88-96 madhigirii. Asi nejira riri pamusoro, musiyano unouya. Iyo yakachipa nzira yekuvandudza mashandiro echigayo chekupedzisira ndeyekuwedzera iyo chaiyo coating. Inogona kuwedzera hupenyu hwekushandisa uye kuita.

Ndeapi mabhangi ekutanga e end mill pamusika?

1.TiN - Titanium Nitride - yakakosha general-chinangwa kupfeka inodzivirira coating

TiN ndiyo yakajairika kupfeka uye abrasion inodzivirira yakaoma coating. Inoderedza kupokana, inowedzera kugadzikana kwemakemikari uye tembiricha uye inoderedza kunamatira kwezvinhu zvinowanzoitika panguva yekugadzira simbi dzakapfava. TiN inokodzera kupfekedzwa maturusi anogadzirwa necemented carbides- dhiri, zvigayo zvekugera, zvekucheka maturusi ekuisa, matepi, reamers, punch mapanga, kucheka maturusi, shear uye flexion maturusi, matrices, mafomu, nezvimwewo. Sezvo ichienderana, inogona kushandiswa pamidziyo yekurapa (yekuvhiya nemazino) nemidziyo inoisirwa. Nekuda kwe toni yeruvara rwegoridhe, TiN yakawana kushandiswa kwakakura zvakare sekushongedza kwekushongedza. Iyo yakashandiswa TiN coating inobviswa zviri nyore kubva mumidziyo simbi. Kugadziridzwazve kwemidziyo kunogona kuderedza mitengo kunyanya kana uchishandisa maturusi anodhura.

2.TiCN - Titanium Carbo-Nitride - pfeka jira risingachinji kurwisa ngura inonamira

TiCN yakanakisa-chinangwa coating. TiCN yakaoma uye yakanyanya kusimba kurwisa kupfuura TiN. Inogona kushandiswa kupfekedza maturusi ekucheka, kubaya nekugadzira maturusi, jekiseni mold zvikamu uye zvimwe zvinopfeka. Sezvo iri biocompatible, inogona kushandiswa pazviridzwa zvekurapa uye midziyo inodyarwa. Iyo yekumhanyisa machining inogona kuwedzerwa uye hupenyu hwekushandisa hunogona kukwidziridzwa nekuwanda se8x mukutsamira pane application, inotonhorera uye mamwe machining mamiriro. Iyo TiCN coating inokurudzirwa kuti ishandiswe kune yakaringana kuchekwa nekuda kwekudzika kwayo kudzika kwemafuta. Iyo yakashandiswa TiCN coating inobviswa zviri nyore uye chishandiso chinodzokororwa. Kugadziridzwazve kwemidziyo inodhura kunogona kuderedza mari zvakanyanya.

3. Iyo aluminium-titanium-nitride coating (AlTiN)

Mushonga wekemikari wezvinhu zvitatu zvealuminium, titanium, uye nitrogen. Ukobvu hwekuvharisa huri pakati pe1-4 micrometers (μm).

Chinhu chakakosha cheAlTiN coating ndiko kupikisa kwakanyanya kupisa uye oxidation. Izvi zvinokonzerwa nekuoma kwe nano kwe38 Gigapascal (GPa). Nekuda kweizvozvo, zvinotevera kuti iyo coating system kunyangwe ine kukurumidza kucheka uye tembiricha yekucheka yakakwirira inoramba yakagadzikana. Zvichienzaniswa nematurusi asina kuvharwa, AlTiN coating, zvichienderana nekushandisa, inowedzera hupenyu hwesevhisi hwakapetwa kagumi neina.

Iyo aluminium-containing coating inonyatso kuenderana nematurusi chaiwo, anocheka zvinhu zvakaoma senge e. simbi (N/mm²)

Tembiricha yepamusoro yekushanda i 900° Celcius (approx. 1,650° Fahrenheit) uye yakaenzanisa ne TiN coating 300° Celcius yepamusoro-soro isingadziye.

Kutonhodza hakusungirwe. Kazhinji, zvakadaro, kutonhora kunowedzera hupenyu hwesevhisi yechishandiso.

Sezvataurwa mu TiAlN coating sezvo zvinofanirwa kucherechedzwa kuti coating nesimbi yemudziyo zvinofanirwa kunge zvakafanira kushandiswa mumidziyo yakaoma. Ndosaka takaputira madhiri akakosha akagadzirwa netungsten-carbide neAlTiN.

4.TiAlN - Titanium Aluminium Nitride - pfeka inodzivirira coating yekucheka kukuru

TiAlN ndeyekuputira nekuomarara kwakanyanya uye yakanyanya kupisa uye oxidation kuramba. Kubatanidzwa kwealuminium kwakakonzera kuwedzera kwekupisa kwekupisa kweiyi inoumbwa PVD coating maererano neyakajairwa TiN coating ne100 ° C. TiAlN inowanzoputirwa pamaturusi ekumhanya anoshandiswa paCNC michina yekugadzira zvinhu zvekuoma kwepamusoro uye panguva yakaoma yekucheka mamiriro. TiAlN yakakodzera kunyanya kune monolithic hard metal milling cutters, drill bits, yekucheka maturusi ekuisa uye mapanga ekuumba. Inogona kushandiswa mune yakaoma kana pedyo-yakaoma machining application.
