Izinhlobo Eziyisisekelo Zokunamathela Zokuphela Kwemishini

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.

Yiziphi izimbobo eziyisisekelo zezigayo emakethe?

1. I-TiN - I-Titanium Nitride - inamathela eyisisekelo evamile yokumelana nokuguga

I-TiN iyona ejwayeleke kakhulu ukuguga kanye nenamathelayo eqinile engazweli imihuzuko. Yehlisa ukungqubuzana, ikhuphule ukuzinza kwamakhemikhali nezinga lokushisa, futhi yehlise ukunamathela kokujwayelekile okwenzeka ngesikhathi somshini wezinsimbi ezithambile. I-TiN ilungele amathuluzi okunameka enziwe nge-carbides enosimende- izingcezu zokubhola, izinqamuli zokugaya, okokufaka amathuluzi okusika, ompompi, ama-reamers, imimese yokubhoboza, amathuluzi okusika, amathuluzi okugunda kanye nama-flexion, omatikuletsheni, namafomu. Njengoba i-biocompatible, ingasetshenziswa emathuluzi ezokwelapha (okuhlinzwa namazinyo) kanye namadivayisi afakelwayo. 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 - inamathela engagqoki ngokumelene nokugqwala okunamathelayo

I-TiCN iyi-coating enhle kakhulu yezinjongo zonke. I-TiCN ilukhuni futhi imelana kakhulu kune-TiN. Ingasetshenziselwa ukumboza amathuluzi okusika, amathuluzi okubhoboza nokwenza, izingxenye zesikhunta somjovo, nezinye izinto zokugqoka. Njengoba i-biocompatible, ingasetshenziswa kumathuluzi ezokwelapha kanye namadivayisi afakelwayo. Isivinini somshini singanyuswa futhi impilo yamathuluzi ingathuthukiswa ngokufinyelela ku-8x ekuncikeni kuhlelo lokusebenza, ekupholiseni, nezinye izimo zomshini. Ukufakwa kwe-TiCN kunconywa ukuthi kusetshenziselwe ukusikwa 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-AlTiN-The Aluminium-Titanium-Nitride ()

Kuyinhlanganisela yamakhemikhali yezinto ezintathu i-aluminium, i-titanium, ne-nitrogen. Ugqinsi lokumboza luphakathi kwama-micrometer angu-1-4 (μm).

Isici esikhethekile se-AlTiN coating imelana kakhulu nokushisa kanye ne-oxidation. Lokhu ngokwengxenye kungenxa yobulukhuni be-nano be-38 Gigapascal (GPa). Ngenxa yalokho, kulandela ukuthi uhlelo lokugqoka naphezu kwejubane eliphezulu lokusika kanye nezinga lokushisa eliphakeme lokusika lihlala lizinzile. Uma kuqhathaniswa namathuluzi angagqokile, i-AlTiN enamathelayo, kuye ngohlelo lokusebenza, ikhulisa impilo yesevisi ephindwe izikhathi eziyishumi nane.

Inamathela equkethe i-aluminium ifaneleke kahle kakhulu kumathuluzi anembayo, asika izinto eziqinile njengensimbi (N/mm²)

Izinga lokushisa eliphezulu lokufaka isicelo ngu-900° Celcius (cishe u-1,650° Fahrenheit) futhi liqhathaniswa nembozwe ye-TiN eno-300° Celcius ukumelana nokushisa.

Ukupholisa akuphoqelekile. Ngokuvamile, ukupholisa kwandisa impilo yesevisi yethuluzi.

Njengoba kushiwo ku-TiAlN yokugqoka, kufanele kuqashelwe ukuthi kokubili ukugqoka kanye nensimbi yensimbi kufanele kuhambisane nesicelo ezintweni ezinzima. Kungakho simboze izinsimbi ezikhethekile ezenziwe nge-tungsten-carbide nge-AlTiN.

I-4.TiAlN - i-Titanium Aluminium Nitride - ukunamathela okungagqoki kokusika ngesivinini esikhulu

I-TiAlN iyinamathela enobulukhuni obuhle kakhulu nokumelana nokushisa okuphezulu kanye ne-oxidation. Ukufakwa kwe-aluminium kunyuse ukumelana nokushisa kwale nhlanganisela ye-PVD enamathelayo ngokuphathelene nembobo ye-TiN evamile ngo-100°C. I-TiAlN ivamise ukumbozwa kumathuluzi okusika anesivinini esikhulu asetshenziswa emishinini ye-CNC yokwenza izinto zokuqina okuphezulu 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.

Uma unentshisekelo emikhiqizweni ye-tungsten carbide futhi ufuna ulwazi olwengeziwe nemininingwane, UNGATHI XHUMANA NATHI ngocingo noma nge-imeyili kwesokunxele, noma SITHUMELE IMEYILI ezansi nekhasi.
