Carbide blade kuvala ndi kudula m'mphepete ndizochitika zofala. Pamene tsamba carbide amavala, zimakhudza workpiece processing kulondola, dzuwa kupanga, workpiece quality, etc.; pamene wogwiritsa ntchito awona kuti blade yavala, ayenera kuyankha mwamsanga vutolo. Njira yopangira makina imawunikidwa mosamala kuti adziwe zomwe zimayambitsa kuvala kwa masamba. Ikhoza kuwunikidwa kuchokera ku mbali zotsatirazi:

1. Zovala zapambali

Kuvala m'mbali kumatanthawuza kutayika kwa abrasion kwa mbali ya chida pansi pamphepete mwa choyikapo cha carbide ndipo nthawi yomweyo moyandikana nayo; tinthu tating'onoting'ono ta carbide muzopangira zogwirira ntchito kapena zolimba zolimba zimapaka pachoyikapo, ndi tiziduswa tating'ono ta Coating peeling ndi kukangana kwa tsamba; chinthu cha cobalt chomwe chili mu tsamba la carbide pamapeto pake chimachoka pagalasi la kristalo, ndikuchepetsa kumamatira kwa carbide ndikupangitsa kuti isungunuke.

Momwe mungaweruzire chovala cha flank? Pali kuvala yunifolomu m'mphepete mwake, ndipo nthawi zina zosenda zakuthupi zimamatira kumphepete, kupangitsa kuti malo owonongeka awoneke ngati akulu kuposa malo enieni; masamba ena a aloyi amawoneka akuda atatha kutha, ndipo masamba ena amawoneka onyezimira atavala. Chowala; wakuda ndi zokutira pansi kapena tsinde la tsamba lomwe limawonekera pambuyo pakuyanika pamwamba.

Zotsutsana nazo zikuphatikizapo: choyamba kuyang'ana liwiro la kudula, kuwerengeranso liwiro lozungulira kuti muwonetsetse kuti ndilolondola, ndi kuchepetsa kuthamanga kwa kudula popanda kusintha chakudya;

Chakudya: Wonjezerani chakudya pa dzino (chakudyacho chiyenera kukhala chokwanira kuti zisawonongeke chifukwa cha chitsulo chochepa chachitsulo);

Zida za blade: Gwiritsani ntchito chinsalu chosamva kuvala. Ngati mukugwiritsa ntchito tsamba losatchinga, gwiritsani ntchito mpeni wokutidwa m'malo mwake; yang'anani tsamba la geometry kuti muwone ngati ikukonzedwa pamutu wodula wofanana.

2. Mphepete yosweka

Flank chipping ndi chikhalidwe chomwe chimapangitsa kulephera kuyikapo pamene tinthu tating'ono tating'ono tating'ono tating'onoting'ono tawombedwa m'malo mosokonezedwa ndi kuvala m'mbali. Kuwombera m'mphepete kumachitika pamene pali kusintha kwa katundu, monga kudulidwa kododometsa. Kuwombera m'mphepete nthawi zambiri kumakhala chifukwa cha zinthu zosakhazikika, monga ngati chidacho chiri chachitali kwambiri kapena chogwirira ntchito sichikuthandizidwa mokwanira; kudula kwachiwiri kwa tchipisi kungayambitsenso kukwapula. Zotsutsana nazo zikuphatikiza: kuchepetsa kutalika kwa chipangizocho mpaka mtengo wake wocheperako; kusankha chida chokhala ndi ngodya yayikulu yothandizira; kugwiritsa ntchito chida chozungulira kapena chamfered; kusankha chinthu cholimba kwambiri chopangira chida; kuchepetsa kuthamanga kwa magazi; Kuonjezera kukhazikika kwa ndondomeko; kusintha chip kuchotsa zotsatira ndi zina zambiri. Kuwombera kumaso: Zipangizo zomata zimatha kuyambitsa kubwezeredwa kwa zinthu pambuyo pozidula, zomwe zimatha kupitilira mbali ya chida ndikupangitsa kukangana pakati pa mbali yakumbali ya chida ndi chogwirira ntchito; kukangana kungayambitse kupukuta komwe kungadzetse ntchito kuumitsa kwa workpiece; zidzawonjezera kukhudzana pakati pa chida ndi workpiece, zomwe zidzachititsa kutentha kuchititsa kukula kwa matenthedwe, kuchititsa kuti nkhopeyo ikhale yowonjezereka, zomwe zimachititsa kuti nkhopeyo iwonongeke.

Njira zothana nazo zikuphatikiza: kukulitsa ngodya ya chida; kuchepetsa kukula kozungulira m'mphepete kapena kuwonjezera mphamvu ya m'mphepete; ndikusankha zida zolimba bwino.

3. M'mphepete mwa nsonga

Mukamapanga zida zina zogwirira ntchito, m'mphepete mwake mutha kuchitika pakati pa chip ndi mphepete; kumangidwa m'mphepete kumachitika pamene wosanjikiza mosalekeza wa workpiece zakuthupi laminated mpaka m'mphepete. Mphepete mwam'mphepete mwake ndi mawonekedwe osinthika omwe amadula Malo odulidwa a m'mphepete mwazitsulo amapitirizabe kusungunuka ndikugwirizanitsa panthawiyi. Kutsogolo m'mphepete komanso nthawi zambiri amapezeka nthawi otsika processing kutentha ndi pang'onopang'ono kudula liwiro; liwiro lenileni la m'mphepete kutsogolo zimadalira zinthu kukonzedwa. Ngati zida zowumitsidwa ndi ntchito zimakonzedwa, monga austenitic Ngati thupi limapangidwa ndi chitsulo chosapanga dzimbiri, ndiye kuti m'mphepete mwake m'mphepete mwake mutha kudzikundikira mwachangu pakuya, zomwe zimapangitsa kuwonongeka kwachiwiri pakuwonongeka kwakuya.

Zotsutsana nazo zikuphatikizapo: kuonjezera liwiro la kudula pamwamba; kuonetsetsa kugwiritsa ntchito kozizira bwino; ndikusankha zida zopaka vapor deposition (PVD).

4. Mphepete mwazenera pamphepete

Zitha kuchitikanso pamtunda wambali pansi pamphepete mwa chida. Podula aluminiyamu yofewa, mkuwa, pulasitiki, ndi zipangizo zina, m'mphepete mwa nthiti imayambanso chifukwa cha kusakwanira pakati pa workpiece ndi chida; nthawi yomweyo, m'mphepete mwa tinthu tating'onoting'ono timalumikizana ndi zida zosiyanasiyana zogwirira ntchito. Aliyense workpiece zakuthupi amafuna chokwanira kuchuluka kwa chilolezo. Zida zina zogwirira ntchito, monga aluminiyamu, mkuwa, ndi pulasitiki, zimabwereranso pambuyo podulidwa; kasupe kungayambitse mikangano pakati pa chida ndi workpiece, zomwe zimapangitsa kuti zipangizo zina zogwirira ntchito zigwirizane. Mbali yodula kwambiri.

Zotsutsa zimaphatikizapo: kuonjezera mbali yaikulu ya chithandizo cha chida; kuwonjezera liwiro la chakudya; ndi kuchepetsa kuzungulira kwa m'mphepete komwe kumagwiritsidwa ntchito poyambira.

5. Kutentha ming'alu

Kuphulika kwa kutentha kumayambitsidwa ndi kusintha kwakukulu kwa kutentha; ngati Machining kumafuna wapakatikati kudula monga mphero, kudula m'mphepete adzalowa ndi kutuluka workpiece zakuthupi kangapo; izi zidzawonjezera ndi kuchepetsa kutentha komwe kumagwiritsidwa ntchito ndi chida, ndipo kusintha kobwerezabwereza kwa kutentha kumayambitsa kukula ndi kutsika kwa zigawo za pamwamba pa zida pamene zimatentha panthawi yodulidwa ndikuzizira pakati pa mabala; pamene choziziritsa sichinayikidwa bwino, choziziritsira chingayambitse kutentha kwakukulu, kufulumizitsa kung'ambika kotentha, ndi Kupangitsa chida kulephera msanga. Kutentha kumagwira ntchito yofunika kwambiri pa moyo wa zida ndi kulephera kwa zida; ming'alu yotentha ndi mawonetseredwe a ming'alu ya nthiti ndi m'mphepete mwa mphepete. Mayendedwe awo ali pa ngodya zolondola mpaka kumapeto. Ming'alu imayambira pamalo otentha kwambiri pamtunda, nthawi zambiri kutali ndi mphepete. Pali mtunda pang'ono pakati pa m'mphepete, ndiyeno umafika ku angatenge nkhope ndi m'mwamba pa m'mbali nkhope; ming'alu yotentha yomwe ili pankhope ndi m'mbali mwake imalumikizidwa pamapeto pake, zomwe zimapangitsa kuti mbali yakumbali ya m'mphepete mwake ikhale yodula.

Zotsutsana nazo zikuphatikiza: kusankha zida zodulira zomwe zili ndi tantalum carbide (TAC) zida zoyambira; kugwiritsa ntchito kozizira bwino kapena kusagwiritsa ntchito; kusankha zida zolimba kwambiri, etc.
