Izinhlobo zama-basic coatings ze-end mill

I-carbide end mill yaziwa nangokuthi i-cemented carbide end mill. Ubulukhuni bethuluzi ngokwalo ngokuvamile buphakathi kwe-HRA88-96 degrees. Kodwa nge-coating ebusweni, umehluko ufika. Indlela eshibhile yokuthuthukisa ukusebenza kwesigayo sokuphela ukufaka i-coating efanele. Inganweba impilo yamathuluzi nokusebenza.

Ayini ama-coatings ayisisekelo e-end mill emakethe?

I-1.TiN - I-Titanium Nitride - inamathela eyisisekelo evikela ukugqokwa kwenjongo evamile

I-TiN iyona evame kakhulu ukuguga kanye nenamathela eqinile ekwazi ukumelana nemihuzuko. Yehlisa ukungqubuzana, ikhuphule ukuzinza kwamakhemikhali nezinga lokushisa futhi inciphise ukunamathela kokujwayelekile okwenzeka ngesikhathi somshini wezinsimbi ezithambile. I-TiN ifanele ukunameka ngamathuluzi enziwe nge-carbides enosimende- izingcezu zokubhoboza, izinsimbi zokugaya, izinsimbi zokusika, ompompi, ama-reamers, imimese yokubhoboza, amathuluzi okusika, amathuluzi okugunda kanye ne-flexion, ama-matrices, amafomu, njll. Njengoba i-biocompatible, ingakwazi zisetshenziswe kumathuluzi ezokwelapha (ukuhlinzwa namazinyo) kanye nezinto ezifakelwayo. Ngenxa yethoni yombala wayo osagolide, i-TiN ithole ukusetshenziswa okubanzi futhi njengokuhlobisa. I-TiN coating esetshenzisiwe isuswa kalula ezinsimbi zamathuluzi. Ukulungiswa kabusha kwamathuluzi kungehlisa kakhulu izindleko ikakhulukazi uma kusetshenziswa amathuluzi abizayo.

I-2.TiCN - i-Titanium Carbo-Nitride - gqoka ukunamathela okuqinile ngokumelene nokugqwala okunamathelayo

I-TiCN iyi-coating enhle kakhulu yezinjongo zonke. I-TiCN ilukhuni futhi imelana kakhulu kune-TiN. Ingasetshenziselwa ukumboza amathuluzi okusika, ukubhoboza nokwenza amathuluzi, izingxenye zesikhunta somjovo nezinye izinto zokugqoka. Njengoba i-biocompatible, ingasetshenziswa kumathuluzi ezokwelapha kanye namadivayisi afakelwayo. Ijubane lomshini lingandiswa futhi impilo yamathuluzi ingathuthukiswa ngokufinyelela ku-8x ekuncikeni kuhlelo lokusebenza, ekupholiseni kanye nezinye izimo zomshini. Ukufakwa kwe-TiCN kunconywa ukuthi kusetshenziselwe ukusika okupholile ngokwanele ngenxa yokuqina kwayo okuphansi kokushisa. I-TiCN esetshenzisiwe icwecwe kalula futhi ithuluzi liboshwe kabusha. Ukulungiswa kabusha kwamathuluzi abizayo kunganciphisa kakhulu izindleko.

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

Kuyinhlanganisela yamakhemikhali yezinto ezintathu i-aluminium, i-titanium, ne-nitrogen. Ugqinsi lwe-coating luphakathi ku-1-4 micrometers (μm).

Isici esikhethekile se-AlTiN coating ukumelana okuphezulu kakhulu nokushisa kanye ne-oxidation. Lokhu ngokwengxenye kungenxa yobulukhuni be-nano be-38 Gigapascal (GPa). Ngenxa yalokho, kulandela ukuthi isistimu yokumboza naphezu kwesivinini sokusika esiphezulu kanye nezinga lokushisa eliphezulu lokusika lihlala lizinzile. Uma kuqhathaniswa namathuluzi angamboziwe, i-AlTiN coating, ngokuya ngohlelo lokusebenza, ikhulisa ukuphila kwesevisi okuphindwe izikhathi eziyishumi nane.

I-coating ene-aluminium ephezulu ifaneleka kahle kakhulu kumathuluzi anembayo, asika izinto eziqinile njengesib. insimbi (N/mm²)

Izinga lokushisa eliphezulu lohlelo lokusebenza ngu-900° Celcius (approx. 1,650° Fahrenheit) futhi liqhathanise ne-TiN coating angu-300° Celcius ukumelana nokushisa.

Ukupholisa akuphoqelekile. Nokho, ngokuvamile, ukupholisa kwandisa impilo yesevisi yethuluzi.

Njengoba kushiwo ku-TiAlN coating ngokujwayelekile kufanele kuqashelwe ukuthi kokubili okokunamathisela nensimbi yensimbi kufanele kulungele ukusetshenziswa ezintweni eziqinile. Kungakho simboze izinsimbi ezikhethekile ezenziwe nge-tungsten-carbide nge-AlTiN.

I-4.TiAlN - I-Titanium Aluminium Nitride - gqoka ukumelana nokusika ukusika kwesivinini esikhulu

I-TiAlN iyinamathela enobulukhuni obuhle kakhulu nokumelana nokushisa okuphezulu kanye ne-oxidation. Ukufakwa kwe-aluminium kuholele ekwenyukeni kokumelana okushisayo kwalokhu kuhlanganiswe kwe-PVD okuhlanganiswe ngokuphathelene nokwembozwa kwe-TiN okujwayelekile ngo-100°C. I-TiAlN ivamise ukumbozwa kumathuluzi okusika ngesivinini esiphezulu asetshenziswa emishinini ye-CNC yokwenza izinto eziqinile futhi ezimeni ezinzima zokusika. I-TiAlN ifaneleka ngokukhethekile abasiki bensimbi abaqinile be-monolithic, izinsimbi zokubhoboza, okokufaka amathuluzi okusika nemibese yokubumba. Ingasetshenziswa ezinhlelweni zokusebenza zemishini ezomile noma eziseduze.
