Ukuqonda iiMilling Cutters: Iimpawu kunye neendidi

Iimpawu eziphambili zeMilling Cutters

Abasiki bokusika baneempawu ezithile zoyilo ezichaza ukusebenza kwazo kunye nokufaneleka kwazo kwimisebenzi eyahlukeneyo yokugaya. Ezi mpawu ziquka imo yazo iyonke, inani kunye noyilo lweeflute zazo, kunye nezinto eziziqulatheyo.

Izinto eziphambili zoyilo zichaza iimpawu zokusebenza kwesixhobo sokusika. Ezi ziquka:

• Imilo: Izicucu ziza ngeemilo ezahlukeneyo zemizi-mveliso.
• Iifluti/Amazinyo: Inani leeflute, okanye amazinyo, lichaphazela ngokuthe ngqo izinga lokususwa kwezinto. Amazinyo amaninzi adla ngokukhokelela ekususweni kwezinto ngokukhawuleza. Iiflute ziindlela ezinde ezijikelezileyo, kwaye incakuba ebukhali ecaleni komphetho yenza izinyo.
• I-Angle yeHelix: Iiflute ze-Helical zivumela izinyo ukuba lingene kancinci kancinci kwizinto ezisetyenzisiweyo. Olu yilo lunciphisa ukungcangcazela kwaye luphucula ukuchaneka kunye nomgangatho womphezulu. Izicucu zokugqiba zihlala zine-engile ephezulu yerake, oko kuthetha ukuba i-helix eqinileyo, ukuze igqitywe kakuhle. Ii-engile ze-helix eziphezulu zisebenza kakuhle kwiintsimbi ezithambileyo, ngelixa ii-engile ze-helix eziphantsi zilungele iintsimbi ezinzima okanye ezinzima. I-engile ephezulu ye-helix ikwaphucula isenzo sokucheba, nto leyo enciphisa amandla okusika kunye nobushushu. Olu yilo luphucula ukukhutshwa kwe-chip ngokuphakamisa ii-chips ziphume kwaye zihambe kwindawo yokusebenza. Ngokwahlukileyo koko, isixhobo se-helix esicothayo, esihlala singaphantsi kwama-40°, sinokusokola ukuphuma kwe-chip, okunokubangela ukugqitywa okunzima.

Ikwavumela nokudalwa kwemisonto emininzi, into engenakufezwa kukucofa kwendabuko.

Indlela Abasiki Bokusika Abasebenza Ngayo Nezicelo Zabo

Iindlela Zokusika Izinto Zokusika Izinto

Izicucu zokusila zisusa izinto ngokusebenzisana okuntsonkothileyo kwamandla kunye nejiyometri yesixhobo. Njengoko isixhobo sijikeleza kwaye sibandakanya umsebenzi, sisebenzisa amandla aliqela. Amandla e-tangential (Ft) aqhuba isenzo sokwenyani sokusika. Amandla e-radial (Fr) asebenza ngokuthe nkqo kwicala lokusika, ngelixa amandla e-axial (Fa) esebenza kwi-axis yesixhobo. Malunga ne-70% yamandla apheleleyo ngamandla e-tangential okusika, oyisa ukumelana nokujikeleza. Ijiyometri yomphetho wokusika ichaphazela kakhulu ukwakheka kwe-chip. Umphetho wokusika ogobileyo, umzekelo, unokubangela ukuba i-chip yahlukane, okubangela ubukhulu be-chip obulinganisiweyo obukhulu kunokuba kubalwe kunye nobude be-chip obuncitshisiweyo. Uyilo lwazo zombini izinto ezifakwayo kunye nemiphetho yokusika eqinileyo, kuquka iipateni ezijijekileyo nezirhabaxa, zibalulekile ekuqikeleleni ukusasazwa kobukhulu be-chip.

Ukusila okuqhelekileyo ngokuchaseneyo nokukhuphuka nge-Milling Cutters

Imisebenzi yokusila isebenzisa iindlela ezimbini: eqhelekileyo kunye neyokusila yokunyuka. Ezi ndlela zahlukile kwindlela isixhobo sokusika esibamba ngayo umsebenzi. Kwi-climb milling, ubukhulu be-chip buqala kubuninzi baso kwaye bunciphe kancinci kancinci. Le nkqubo inciphisa ukungqubana nobushushu. Ngokwahlukileyo koko, i-cutting milling eqhelekileyo iqala ngomphetho wokusika ongenabo ubukhulu, kwaye i-chip ifumana ubukhulu kancinci kancinci njengoko ibamba izinto. Oku kunokukhokelela ekukhuhleni endaweni yokusikwa okucocekileyo. I-climb milling iqondisa amandla okusika ezantsi, ngelixa i-climber milling isebenza phezulu. Lo mahluko uchaphazela ukuguguleka kwesixhobo, kunye ne-climb milling enciphisa ngenxa ye-thinning chip.

Ukusetyenziswa Okusebenzayo Kwezixhobo Zokusika

Izicucu zokusila zisetyenziswa kakhulu kumashishini ahlukeneyo. Kwicandelo leenqwelo-moya, zibalulekile ekucutshungulweni kweendawo ezichanekileyo, kuquka izinto zenjini, izakhiwo ze-fuselage, kunye nezihlanganisi.

Izinto Ezibalulekileyo Eziqwalaselwe Kwizixhobo Zokusika I-Milling Cutters

Izinto ezisetyenziswa kwisixhobo somsebenzi zichaza iimpawu ezifunekayo zesiseko somsiki wokugaya. Umatshini wokwakha izinto ezinobunzima obuphezulu, njengentsimbi eqinileyo kuluhlu lwe-60-70 HRC, uvelisa uxinzelelo olukhulu lobushushu kunye noomatshini. Le ndawo ifuna izinto ezisemgangathweni zesiseko ezifana ne-ultra-fine grain carbide. Ezi zinto zibonelela ngobunzima obuphezulu kunye nokumelana nokuqhekeka, zithintela ukuwohloka komphetho ngokukhawuleza, ukuqhekeka okuncinci, kunye nokuthamba kwezinto zesixhobo ngenxa yobushushu. Uhlobo lokurhawuzelela kwezinto eziqinileyo lukwanyusa ukuguguleka kwezixhobo, okwenza izinto eziqinileyo zibe yimfuneko ekugcineni ukuchaneka kunye nokwandisa ubomi bezixhobo. Ukongeza, iingubo ezikhethekileyo ezifana ne-AlTiN zisebenza kwezi substrates ukwenza isikhuselo sobushushu, ziqondisa ubushushu kude nesixhobo kwaye zigcine ukuqina kwesakhiwo saso phantsi kweemeko eziqhubekayo zomthwalo ophezulu.

Izinto ezithambileyo, ezifana neentsimbi ezingezizo i-ferrous (ISO N), zivumela isantya esiphezulu sokusika kunye nobomi bezixhobo obude kunye nee-inserts ezinemiphetho ebukhali. Oku kuthetha iimfuno ezingqongqo kakhulu zokuqina kwe-substrate kunye nokumelana nobushushu. Ukukhethwa kwejometri yesixhobo sokusika, inqanaba, kunye nedatha yokusika kuchaphazeleka ziimpawu ezizodwa zesixhobo ngasinye, kubandakanya izinto zokudibanisa, unyango lobushushu, kunye nobunzima. Izinto zokusebenza zahlulwe zangamaqela amathandathu amakhulu (ISO P, M, K, N, S, H) aneempawu ezizodwa zoomatshini. Umzekelo, i-ISO H ibandakanya iintsimbi ezinobunzima obuphakathi kwe-45-65 HRC, ezinzima ukuzisebenzisa ngomatshini, zivelise ubushushu, kwaye zirhabaxa kakhulu kumda wokusika.

Izinto zeJometri zeMilling Cutters

Uyilo lwejometri yesikhiphi sokusila luyichaphazela kakhulu indlela esebenza ngayo kunye nokuzinza kwayo ngexesha lokusebenza. Ububanzi obuphambili, inxalenye eqinileyo esembindini wesixhobo sokusila, bubalulekile ekuqineni nasekuxhathiseni kwayo ukugoba. Ububanzi obukhulu obuphambili buphucula ukuqina kwesixhobo, nto leyo eyenza singabi sengozini yokugoba phantsi kwamandla okusika, ingakumbi kwizixhobo ezineeflethi ezinde apho ukugoba kunokwandiswa khona. Ukwandisa ububanzi obuphambili ngobuchule kuphucula ukuqina, nto leyo enceda ekusebenzeni ngamandla aphezulu asecaleni okanye ekunqumleni okunzulu.

Ukuqina kwesixhobo kubalulekile ekunciphiseni ukujikajika. Ukugoba kuchaphazeleka ngokuthe ngqo bubude be-overhang kunye nobubanzi besixhobo; ukwandisa ukufikelela kwesixhobo kunciphisa uzinzo lwenkqubo. Ukuze kuphuculwe ubomi besixhobo, ukujikajika kufuneka kugcinwe ngaphantsi kwe-0.001 intshi, okanye ngaphantsi kwezixhobo ezincinci. Ukunciphisa ukujija kwesixhobo kuchaphazela kakhulu ukujikajika, kunye nokuncipha kwama-20% kubude be-overhang okukhokelela ekunciphiseni kwama-50% ekujikeni.

Cinga ngala manqaku ukuze uphucule uzinzo kunye nokunciphisa ukuphambuka:

• Khetha ii-end mills ezinobubanzi obukhulu ukuze uzinze ngakumbi.
• Nciphisa i-overhang ukusuka kwimpumlo ye-spindle ukuya kwincam yesixhobo.
• Sebenzisa ii-stub length end mills nanini na xa kunokwenzeka ukunciphisa ukuphambuka.
• Kwizixhobo zokusika ezingama-90°, amandla amakhulu e-radial abangela ukuphambuka ngee-overhangs ezinde.
• Soloko usebenzisa ubude besixhobo obufutshane kangangoko.
• Ukungcangcazela kubonakala ngakumbi xa ii-overhangs zidlula ubukhulu besixhobo ngokuphindwe kane.

Kwi-milling, zombini ii-engile ze-radial kunye ne-axial rake ziyachazwa kuba nganye inefuthe lokuphambuka kwe-chip kunye namandla omphetho kwiindlela ezahlukeneyo. Ezi engile zidibene zichaphazela iziphumo zoomatshini ngokubanzi ezifana nokwakheka kwe-chip, amandla okusika, kunye nokugqitywa komphezulu. I-engile ye-axial rake inefuthe ekuhambeni kwe-chip, amandla okusika, kunye nokusetyenziswa kwamandla. Abenzi bezixhobo banokulungisa le engile ukunciphisa amandla okusika, okuvumela oomatshini abanamandla angaphantsi kwamandla ukuba basetyenziswe ngokufanelekileyo. I-engile ye-radial rake, kwelinye icala, ibalulekile ekumiseleni ubukhali kunye namandla omphetho wokusika.

Ukugquma kunye nokusebenza kweMilling Cutters

Iingubo zokwaleka ziphucula kakhulu ukusebenza kunye nobude bexesha lezixhobo zokusika. Iingubo zokwaleka zeAluminium Titanium Nitride (AlTiN) zinzima kuneTitanium Aluminium Nitride (TiAlN), zinika ukumelana okuphezulu kokurhabaxa kunye nobushushu. Oku kwandisa ubomi bezixhobo kwaye kunciphisa imijikelo, ngakumbi kwizixhobo zokulungisa iinqwelo-moya kunye neenqwelo-moya, ii-alloys ze-nickel, iintsimbi ezingenasici, ii-alloys ze-titanium, isinyithi esityhidiweyo, kunye neentsimbi zekhabhoni.
