Iintlobo zokugquma eziSisiseko zoMll Mill

I-carbide end mill yaziwa ngokuba yi-cemented carbide end mill. Ukuqina kwesixhobo ngokwawo kuphakathi kwe-HRA88-96 degrees. Kodwa ngokutyabeka phezu komhlaba, umahluko uyeza. Eyona ndlela inexabiso eliphantsi yokuphucula ukusebenza kwe-end Mill kukongeza isambatho esifanelekileyo. Inokwandisa ubomi besixhobo kunye nokusebenza.

Zeziphi ezona zinto zisisiseko zokugquma ii-mills kwimarike?

1. I-TiN - i-Titanium Nitride - isiseko esisisiseko-injongo jikelele yokunxiba i-resistant coating

I-TiN yeyona nto ixhaphakileyo yokunxiba kunye ne-abrasion-resistant-standing coating. Yehlisa ukukhuhlana, yonyusa uzinzo lwekhemikhali kunye nobushushu, kwaye yehla ukuncamathela kwemathiriyeli ehlala isenzeka ngexesha lokwenziwa kweentsimbi ezithambileyo. I-TiN ifanelekile kwizixhobo zokugquma ezenziwe ngeekhabhidi ezinesamente- i-drill bits, i-milling cutters, izixhobo zokusika izixhobo, iimpompo, ii-reamers, iimela ze-punch, izixhobo zokusika, izixhobo zokucheba kunye ne-flexion, iimatriki kunye neefom. Ekubeni i-biocompatible, ingasetyenziselwa izixhobo zonyango (utyando kunye namazinyo) kunye nezixhobo ezifakelwayo. Ngenxa yethowuni yombala wegolide, i-TiN ifumene ukusetyenziswa ngokubanzi njengengubo yokuhombisa. Ingubo ye-TiN esetyenzisiweyo ikhutshwe ngokulula kwiintsimbi zesixhobo. Ukulungiswa ngokutsha kwezixhobo kunokunciphisa kakhulu iindleko, ngakumbi xa kusetyenziswa izixhobo ezibiza imali eninzi.

I-2.TiCN - i-Titanium Carbo-Nitride - isambatho esingagugiyo kwi-corrosion encamathelayo

I-TiCN yeyona nto igqwesileyo yenjongo zonke. I-TiCN inzima kwaye iyaxhathisa ngaphezu kwe-TiN. Ingasetyenziselwa ukugquma izixhobo zokusika, ukubethelwa kunye nokwenza izixhobo, iinxalenye zokungunda inaliti, kunye nezinye izinto zokunxiba. Ekubeni i-biocompatible, inokusetyenziswa kwizixhobo zonyango kunye nezixhobo ezifakelwayo. Isantya somatshini sinokunyuswa kwaye ubomi besixhobo bunokwandiswa ngokufikelela kwi-8x ekuxhomekeke kwisicelo, ukupholisa, kunye nezinye iimeko zomatshini. Ingubo ye-TiCN iyacetyiswa ukuba isetyenziswe ukusika okupholile ngokwaneleyo ngenxa yokuzinza kwayo okuphantsi kwe-thermal. I-coating ye-TiCN esetyenzisiweyo ikhutshwe ngokulula kwaye isixhobo siphinde sifakwe kwakhona. Ukulungiswa kwakhona kwezixhobo ezibizayo kunokunciphisa kakhulu iindleko.

3. I-AlTiN-I-Aluminium-Titanium-Nitride yokwaleka ()

Yikhompawundi yemichiza yezinto ezintathu ialuminiyam, ititanium, kunye nenitrogen. Ubunzima bokugquma buphakathi kwe-1-4 micrometers (μm).

Isici esikhethekileyo sokugquma kwe-AlTiN ixhathisa kakhulu ukushisa kunye ne-oxidation. Oku kuyingxenye ngenxa yobunzima be-nano ye-38 Gigapascal (GPa). Ngenxa yoko, kulandela ukuba inkqubo yokwambathisa nangona isantya esiphezulu sokusika kunye nobushushu obuphezulu bokusika buhlala buzinzile. Xa kuthelekiswa nezixhobo ezingagqunywanga, ukugquma kwe-AlTiN, kuxhomekeke kwisicelo, kwandisa amaxesha alishumi elinesine kubomi benkonzo obude.

I-aluminiyam ene-aluminiyam ephezulu ifaneleke kakhulu kwizixhobo ezichanekileyo, ezisika izinto eziqinileyo njengentsimbi (N/mm²)

Iqondo lokushisa eliphezulu lesicelo liyi-900 ° Celcius (malunga ne-1,650 ° Fahrenheit) kwaye lithelekisa ne-TiN yokugqoka kunye ne-300 ° Celcius yokumelana nokushisa.

Ukupholisa akunyanzelekanga. Ngokubanzi, ukupholisa ukongezelela kwandisa ubomi benkonzo yesixhobo.

Njengoko kukhankanyiwe kwi-TiAlN yokugqoka, kufuneka kuqatshelwe ukuba zombini iingubo kunye nesixhobo sensimbi kufuneka silungele isicelo kwizinto ezinzima. Yiyo loo nto siye sagquma iidrill ezikhethekileyo ezenziwe ngetungsten-carbide ngeAlTiN.

I-4.TiAlN-i-Titanium Aluminium Nitride-i-Aluminiyamu yeNyitridi yokunxiba enganxitywayo yokusika ngesantya esiphezulu

I-TiAlN yiyaleko enobunzima obugqwesileyo kunye nokumelana ne-thermal kunye ne-oxidation ephezulu. Ukufakwa kwe-aluminium kwandisa ukuxhathisa kwe-thermal yale ngqungquthela ye-PVD edibeneyo ngokumalunga nomgangatho oqhelekileyo we-TiN wokugquma nge-100 ° C. I-TiAlN idla ngokugqunywa kwizixhobo zokusika ngesantya esiphezulu ezisetyenziswa kumatshini we-CNC wokwenza izinto zomatshini wokuqina okuphezulu kunye neemeko ezinzima zokusika. I-TiAlN ifaneleka ngokukodwa kwi-monolithic hard metal milling cutters, i-drill bits, ukufaka izixhobo zokusika, kunye neemela zokubumba. Ingasetyenziswa kwizicelo zomatshini ezomileyo okanye ezikufutshane nezomileyo.

Ukuba unomdla kwiimveliso ze-tungsten carbide kwaye ufuna ulwazi oluthe kratya kunye neenkcukacha, ungaQHAGAMSHELANA NATHI ngefowuni okanye ngeposi ekhohlo, okanye SITHUMELE MAIL emazantsi ephepha.
