1. Kutheni ukhetha ukufaka i-carbide kwi-CNC machining?

I-Carbide ifaka, njengoko igama libonisa, imveliso yayo ephambili yi-carbide ene-cemented. I-carbide ene-cemented yenziwe nge-refractory metal carbide kunye ne-metal binder powder emva kokucubungula. Ngenxa yokuba ezi carbides zetsimbi zinezinga eliphezulu lokunyibilika, ubunzima obuphezulu kunye nokuzinza kakuhle kweekhemikhali, i-carbides ene-cemented equlethe isixa esikhulu se-refractory metal carbides nayo ineempawu zale carbides ye-refractory metal. Ke ngoko, ukufakwa kwe-carbide kunobunzima obuphezulu, ukumelana nokunxiba, kunye nokumelana nobushushu. Ubunzima bokufakwa kwe-carbide esetyenziswa ngokuqhelekileyo yi-89～93HRA, ephezulu kunobunzima bentsimbi yesantya esiphezulu (83～86.6HRA). Kwaye ukufakwa kwe-carbide kuchasene nokushisa okuphezulu. Ukufakwa kweCarbide kunokusika izinto kwiqondo lobushushu obuphezulu be-800～1000℃. Ukusebenza kokusika kokufakwa kwe-carbide kuphezulu kakhulu kunezixhobo zetsimbi ezikhawulezayo. Ukuqina kokufakwa kwe-carbide ngamaxesha amaninzi kwezinye izinto ezifakiweyo. Xa ukuqina kufana, ukufakwa kwe-carbide kunokunyusa isantya sokusika ngama-4 ukuya kwamaxesha angama-10.

2. Ukusetyenziswa kokufakwa kwe-carbide kwi-CNC machining

Ngenxa yobunzima obuphezulu kunye nokumelana nokushisa kokufakwa kwe-carbide. Ke ngoko, i-CNC machining ihlala ikhetha izixhobo zokusika i-carbide kwiileyile zokusika izixhobo. Izinto ezihlanganisiweyo, iiplastiki zemizi-mveliso, izinto zeglasi ephilayo kunye nezixhobo zetsimbi ezingenayo i-ferrous kwimarike zonke ziyasikwa kwaye zicutshungulwe ngezixhobo zokusika i-carbide kwiilayile. I-carbide ene-cemented ihlukaniswe ngamacandelo amabini: i-tungsten-cobalt alloy (YG) kunye ne-tungsten-cobalt-titanium alloy (YT). I-alloys ye-tungsten-cobalt inobunzima obuhle. Izixhobo ezenziwe nge-tungsten-cobalt alloys zilula ukukhubazeka kwinkqubo yokusika, ukusika kukhanya kwaye ngokukhawuleza, kwaye ii-chips akulula ukunamathela kwimela. Ngoko ke, ngokubanzi, siya kukhetha izixhobo ezenziwe nge-tungsten-cobalt alloy ukucubungula insimbi engenasici. I-Tungsten-cobalt-titanium alloy i-alloy-resistant ngakumbi kune-tungsten-cobalt alloy phantsi kweemeko eziphezulu zokushisa. Kodwa i-brittle kwaye ayixhathisi kwimpembelelo. Ngoko ke, siya kukhetha izixhobo ezenziwe nge-tungsten-cobalt-titanium alloy ukucubungula izinto zeplastiki, ezifana nentsimbi.

3. Uphuhliso lwexesha elizayo lokufakwa kwe-carbide kwi-CNC machining

Ngophuhliso oluqhubekayo lwesayensi kunye nobuchwepheshe kunye nokuphuculwa okuqhubekayo kwinqanaba lemveliso, ukutshintshwa kwezixhobo zoomatshini ukusuka koomatshini besiqhelo besiqhelo ukuya koomatshini be-CNC yinto engenakunqandwa. Izixhobo zokusika i-Carbide kwiileyile zidlala indima ebalulekileyo ekulungiseni nasekuphuculeni isakhiwo soshishino. Izixhobo zokusika i-Carbide ze-lathes zinokuphucula ngokufanelekileyo isivuno semveliso kunye nomgangatho. Ulawulo lwamanani omatshini yindlela yokuphucula ishishini lomatshini, kwaye imfuno yezixhobo zolawulo lwamanani nayo iya kwanda. Njengenxalenye ebalulekileyo ye-CNC yomatshini wokusika isinyithi, ukufakwa kwe-carbide kuya kuqhuba imfuno yabathengi bezixhobo ze-CNC, nokuba ziimfuno zezixhobo zezixhobo ze-stock machine okanye imfuno eyongezelelweyo yezixhobo ezintsha zomatshini minyaka yonke. Ngexesha elifanayo, ukufakwa kwe-carbide kukutya. Ukuba ukufakwa kwe-carbide kugqitywe kwinqanaba elithile, kufuneka batshintshwe ngexesha. Ke ngoko, imfuno yokufaka i-carbide kwimarike isenkulu.

Oku ngasentla ngumxholo weli nqaku, ndiyathemba ukuba eli nqaku linokusombulula ingxaki yakho kwaye likuncede ukhethe ukufakwa kwe-carbide engcono kakhulu. Ukuba uyayifuna, wamkelekile ukuba uqhagamshelane nathi. Singumvelisi oqeqeshiweyo kwaye sinokukubonelela ngeemveliso ezilungileyo kakhulu, ezinje nge-tungsten carbide inserts, carbide grooving insert, carbide threading insert.
