Ukunxitywa kwe-Carbide blade kunye ne-edge chipping zizinto eziqhelekileyo. Xa i-carbide blade inxiba, ichaphazela ukuchaneka kwe-workpiece processing, ukusebenza kakuhle kwemveliso, umgangatho womsebenzi, njl.; xa umqhubi ebona ukuguga kweeblade, kufuneka aphendule ngokukhawuleza kwingxaki. Inkqubo yomatshini ihlalutywa ngononophelo ukuze kuchongwe izizathu ezisisiseko zokugqoka i-blade. Inokuhlalutywa kule miba ilandelayo:
1. Ukunxitywa komphezulu weflanki
I-Flank wear ibhekisela ekulahlekeni kwe-abrasion ye-flank yesixhobo ngaphantsi komphetho wokusika we-carbide efakwe kwaye ngokukhawuleza isondele kuyo; amaqhekeza e-carbide kwizinto zokusebenza okanye izinto eziqiniweyo zixubha ngokuchasene nokufakwa, kunye neencinci ezincinci ze-Coating peeling kunye ne-blade friction; i-cobalt element kwi-carbide blade ekugqibeleni iyahlukana ne-crystal lattice, inciphisa ukunamathela kwe-carbide kwaye ibangele ukuba ihlambuluke.
Indlela yokugweba isinxibo seflank? Kukho i-uniform yokugqoka ecaleni kwe-cut cut, kwaye ngamanye amaxesha i-peeling workpiece material ibambelela kumda wokusika, okwenza ukuba ubuso obunxibileyo bubonakale bukhulu kunommandla wangempela; ezinye iincakuba zealloyi zibonakala zimnyama emva kokunxiba, kwaye ezinye iincakuba zibonakala zimenyezela emva kokunxiba. Bright; Umnyama ngumgquba ongezantsi okanye isiseko sencakuba eboniswe emva kokuba umphezulu wokwambathisa uxobukile.
Imilinganiselo yokuchasana ibandakanya: okokuqala ukujonga isantya sokusika, ukubala kwakhona isantya sokujikeleza ukuqinisekisa ukuchaneka kwayo, kunye nokunciphisa isantya sokusika ngaphandle kokutshintsha ukutya;
Ukutya: Yandisa isondlo ngezinyo ngalinye (isondlo kufuneka sibe phezulu ngokwaneleyo ukuthintela ukuguga okubangelwa bubungqingqwa bentsimbi encinci yentsimbi);
Imathiriyeli yeBlade: Sebenzisa imathiriyeli yencakuba ekwazi ukunxiba. Ukuba usebenzisa i-blade engagqunywanga, sebenzisa i-blade egqunyiweyo endaweni yoko; khangela ijiyometri yeblade ukugqiba ukuba icutshungulwa kwintloko yomsiki ehambelanayo.
2. Umphetho owaphukileyo
I-Flank chipping yimeko ebangela ukusilela kokufaka xa amasuntswana amancinci omgca wokusika egqabhukile kunokuba agqabhuke kukunxiba kweflank. I-Flank chipping yenzeke xa kukho utshintsho kwimithwalo yempembelelo, njengokusika okuphazamisekileyo. I-Flank chipping idla ngokuba sisiphumo seemeko ezingazinzanga, njengaxa isixhobo siside kakhulu okanye i-workpiece ingaxhaswanga ngokwaneleyo; ukusika okwesibini kweetshiphusi kunokubangela ukutshiphuza ngokulula. Amanyathelo okulwa abandakanya: ukunciphisa ubude beprotrusion yesixhobo ukuya kwixabiso eliphantsi; ukukhetha isixhobo esine-angle enkulu yokunceda; usebenzisa isixhobo esinomphetho ojikelezileyo okanye odibeneyo; ukukhetha into eqinile yokusika isixhobo; ukunciphisa isantya sokutya; Ukwandisa uzinzo lwenkqubo; phucula isiphumo sokususa itshiphu kunye neminye imiba emininzi. I-Rake face spalling: Izixhobo ezincamathelayo zinokubangela ukubuya kwemathiriyeli emva kokusikwa, ezinokudlulela ngaphaya kwe-engile yokukhulula yesixhobo kunye nokudala ingxabano phakathi komphezulu weflank wesixhobo kunye nesixhobo sokusebenza; ukukhuhlana kunokubangela umphumo wokugulisa onokuthi Kuya kukhokelela ekusebenzeni ukuqina komsebenzi; iya kwandisa uqhagamshelwano phakathi kwesixhobo kunye workpiece, nto leyo eya kubangela ukuba ubushushu kubangele ukwanda thermal, ebangela ukuba ubuso iraki ukwandisa, okubangela iharika ubuso ukutsalwa.
Amanyathelo okuthintela abandakanya: ukwandisa i-engile yeharika yesixhobo; ukunciphisa ubungakanani bomda ojikelezayo okanye ukwandisa amandla e-edge; kunye nokukhetha izixhobo ezinobunzima obuhle.
3. Umphetho wendawo kwirakhi
Xa usenza ezinye izinto zokusebenza, i-rake edge ingenzeka phakathi kwe-chip kunye ne-edge yokusika; i-edge eyakhiweyo iyenzeka xa i-layer eqhubekayo yezinto zokusebenza i-laminated kwi-cut cut. Umgca owenziweyo owenziweyo uyisakhiwo esiguquguqukayo esinqumle Umphezulu osikiweyo wecala elakhiweyo liqhubeka likhupha kwaye liphinde lidibanise ngexesha lenkqubo. Umphetho ongaphambili nawo uhlala usenzeka ngamaxesha athile kumaqondo obushushu obuphantsi kunye nezantya zokusika ezicothayo; isantya sangempela somphetho wangaphambili sixhomekeke kwizinto ezicutshungulwayo. Ukuba izinto ezinobunzima bokusebenza zicutshungulwa, ezifana ne-austenitic Ukuba umzimba wenziwe ngensimbi engenasici, ngoko i-rake yendawo yomda ingabangela ukuqokelela ngokukhawuleza kubunzulu bokusikwa, okukhokelela kwimodi yokungaphumeleli kwesibini komonakalo kubunzulu bokusika.
Amanyathelo okuthintela abandakanya: ukwandisa isantya sokusika umphezulu; ukuqinisekisa ukusetyenziswa okuchanekileyo kwesisipholisi; kunye nokukhetha izixhobo ezine-physical vapour deposition (PVD) coating.
4. Umphetho owakhelwe phezulu kwincakuba yeflanki
Inokuthi yenzeke kumphezulu weflank ngaphantsi komphetho wokusika isixhobo. Xa usikwa i-aluminium ethambileyo, ubhedu, iplastiki, kunye nezinye izinto, i-flank edge nayo ibangelwa kukukhutshwa okunganeleyo phakathi kwendawo yokusebenza kunye nesixhobo; kwangaxeshanye, umphetho weflanki Amaqhuqhuva anxulunyaniswa nezinto ezahlukeneyo zokusebenza. Isixhobo ngasinye somsebenzi sifuna isixa esaneleyo sokucocwa. Ezinye izixhobo zokusebenza, ezifana ne-aluminiyam, ubhedu, kunye neplastiki, ziya kuphinda zibuyele emva kokusika; i-spring back inokubangela ingxabano phakathi kwesixhobo kunye ne-workpiece, nto leyo ebangela ukuba ezinye izinto zokusebenza zibophe. Icala elibukhali.
Amanyathelo okulwa abandakanya: ukwandisa i-angle yokunceda engundoqo yesixhobo; ukwandisa isantya sokutya; kunye nokunciphisa ukujikeleza komphetho osetyenziselwa ukunyanga kwangaphambili.
5. Ukuqhekeka kwe-thermal
Ukuqhekeka kwe-Thermal kubangelwa utshintsho olugqithiseleyo kwiqondo lokushisa; ukuba i-machining ibandakanya ukusika okuphakathi okufana nokusila, i-edge yokusika iya kungena kwaye iphume i-workpiece material amaxesha amaninzi; oku kuya kwandisa kwaye kunciphise ubushushu obufunxwe sisixhobo, kwaye utshintsho oluphindaphindiweyo kwiqondo lobushushu luya kubangela ukwanda kunye nokucutheka kwezixhobo zomphezulu wezixhobo njengoko zifudumala ngexesha lokusikwa kunye nokupholisa phakathi kokusikeka; xa isisipholisi singasetyenziswanga ngokuchanekileyo, isisipholisi sinokubangela utshintsho olukhulu lobushushu, sikhawulezise ukuqhekeka okushushu, kwaye Ibangela isixhobo ukuba sisilele ngokukhawuleza. Ubushushu budlala indima ebalulekileyo kubomi besixhobo kunye nokusilela kwesixhobo; ukuqhekeka kwe-thermal kukubonakaliswa kokuqhekeka kwi-rake kunye ne-flank surfaces ye-edge yokusika. Ulwalathiso lwabo lukwi-angles ezichanekileyo ukuya kwinqanaba lokusika. Iintanda ziqala ukusuka kwindawo eshushu kakhulu kwindawo yeraki, ngokuqhelekileyo kude nomphetho wokusika. Kukho umgama omncinci phakathi kwemiphetho, kwaye emva koko udlulele kwi-rake ebusweni nangaphezulu kwi-flank face; Ukuqhekeka kwe-thermal kubuso beraki kunye nobuso beflank ekugqibeleni zidityanisiwe, okukhokelela ekuqhekekeni kobuso beflanki kumphetho wokusika.
Amanyathelo okuthintela abandakanya: ukukhetha izinto zokusika eziqulethe i-tantalum carbide (TAC) izinto ezisisiseko; ukusetyenziswa kwesipholisi ngokuchanekileyo okanye ukungasisebenzisi; ukukhetha izinto ezinzima zokusika, njl.
