I. Yintoni i-High-Feed Milling?
I-High-Feed Milling (efinyeziweyo njenge-HFM) sisicwangciso esiphuhlileyo sokusila kumatshini wanamhlanje we-CNC. Eyona nto iphambili kuyo "bubunzulu obuncinci bokusika kunye nesantya sokutya okuphezulu". Xa kuthelekiswa neendlela zemveli zokusila, obu buchwephesha busebenzisa ubunzulu bokusika obuncinci be-axial (ngokuqhelekileyo busuka kwi-0.1 ukuya kwi-2.0 mm) kunye nezinga eliphezulu kakhulu lokutya kwezinyo (ukuya kumaxesha angama-5-10 okusila ngokwesiko), kudityaniswe nesantya esiphezulu sokuphotha, ukuphumeza umyinge wokutya okumangalisayo.
Ubume benguquko yale ngcamango yokucubungula ilele kuguquko olupheleleyo lwesalathiso samandla okusika, ukuguqula amandla e-radial ayingozi aveliswa ekusileni ngokwemveli abe yi-axial force enenzuzo, ngaloo ndlela yenze isantya esiphezulu kunye nokusebenza ngokufanelekileyo kwenzeke. Intloko yokugaya ukutya okukhawulezayo sisixhobo esikhethekileyo esenzelwe ukuphumeza esi sicwangciso kwaye iye yaba sisixhobo esibalulekileyo sokwenza umngundo wanamhlanje, i-aerospace, kunye nemizi-mveliso yeemoto, phakathi kwabanye.
II. UmGaqo wokuSebenza weHigh-Feed Milling Cutter
Imfihlelo esemva kwesixhobo sokusila esinesondlo esiphezulu silele kuyilo lwaso olukhethekileyo lwe-engile encinci. Ngokungafaniyo nabasiki besintu bokungqusha abane-engile engundoqo ye-45° okanye i-90°, intloko yokusila ekhawulezayo ithatha i-engile encinci ye-10° ukuya kuma-30°. Olu tshintsho kwijiyometri ngokusisiseko lutshintsha isalathiso samandla okusika.
Inkqubo yokuguqulwa komatshini: Xa iblade idibana nomsebenzi, uyilo oluncinci lweraki lweraki lubangela ukuba amandla okusika alathe ikakhulu kwicala le-axial (kunye ne-axis yomzimba wesixhobo) kunokuba isalathiso se-radial (perpendicular to axis) njengakwindlela yokusila yemveli. Olu tshintsho lukhokelela kwiziphumo ezintathu eziphambili:
1. Impembelelo yokunciphisa i-Vibration: Amandla amakhulu e-axial atsalela i-cutter disc "nga" kwi-shaft engundoqo, ebangela ukuba isixhobo sokusika - inkqubo ye-shaft engundoqo ibe kwimeko enzima. Oku kucinezela ngokufanelekileyo ukungcangcazela kunye ne-flutter, ivumela ukusika okugudileyo naphantsi kweemeko ezinkulu zokuxhoma.
2. Impembelelo yokukhusela umatshini: Amandla e-axial athwalwa yi-thrust bearing ye-shaft engundoqo yomatshini. Umthamo wayo wokuthwala uphezulu kakhulu kuneebheringi zeradial, ngaloo ndlela unciphisa umonakalo kwi-shaft engundoqo kunye nokwandisa ubomi besixhobo.
3. Isiphumo sokwandisa ukondla: Iphelisa imida yokungcangcazela, ivumela isixhobo ukuba sijongane namazinga aphezulu kakhulu esondlo ngezinyo ngalinye. Isantya sokutya sinokufikelela kwi-3 ukuya ku-5 amaxesha okugaya okuqhelekileyo, kunye nesantya esiphezulu sifikelela kwi-20,000 mm / min.
Olu yilo lomatshini olunobuchule lwenza ukuba intloko yokusila ngokukhawuleza igcine isantya esiphezulu sokususa isinyithi ngelixa inciphisa kakhulu ukungcangcazela kokusika, ibeka isiseko somgangatho ophezulu wokulungiswa komphezulu.
III. Ezona zinto ziluncedo kunye neempawu zeHigh-Feed Milling Cutter
1. Ukusebenza okuphezulu: Inzuzo ephawulekayo ye-high feed milling cutter yizinga elibalaseleyo lokususa isinyithi (MRR). Nangona ubunzulu bokusika be-axial bungekho nzulu kangako, isantya sokutya siphezulu kakhulu sibuyekeza oku kusilela. Ngokomzekelo, xa umatshini wokugaya i-gantry oqhelekileyo usebenzisa intloko yokugaya i-faed fast fast to process tool, isantya sokutya sinokufikelela kwi-4,500 - 6,000 mm / min, kunye nesantya sokususa isinyithi si-2 - 3 ngamaxesha aphezulu kunama-cutter okugaya amasiko.
2. Umgangatho ogqwesileyo womphezulu: Ngenxa yenkqubo yokusika egudileyo, ukugaya ukutya okukhawulezayo kunokufikelela ukugqiba umgangatho obalaseleyo, ngokuqhelekileyo ukufikelela kwi-Ra0.8μm okanye nangaphezulu. Kwiimeko ezininzi, iindawo ezicutshungulwayo ngokusebenzisa iintloko zokugaya ukutya ngokukhawuleza zinokusetyenziswa ngokuthe ngqo, ukuphelisa inkqubo yokugqiba isiqingatha kunye nokunciphisa kakhulu inkqubo yokuvelisa.
3. Impembelelo ephawulekayo yokonga amandla: Uphando lubonisa ukuba ukusetyenziswa kwamandla okugaya ukutya okukhawulezileyo ngama-30% ukuya kuma-40% angaphantsi kunoko kugutywa kwemveli. Amandla okusika asetyenziswa ngokufanelekileyo ukususwa kwezinto kunokuba asetyenziswe kwi-vibration yesixhobo kunye nomatshini, ukufezekisa ukusetyenzwa okuluhlaza okwenyani.
4. Inokwandisa kakhulu ubomi benkonzo yenkqubo yesixhobo: Inkqubo yokusika iyancipha impembelelo kunye nokugqoka kwisixhobo, kwaye ubomi besixhobo bunokwandiswa ngaphezu kwe-50%. Iimpawu zamandla eradial aphantsi nawo anciphisa umthwalo kumatshini wokuphotha wesixhobo, esenza ukuba afaneleke ngakumbi koomatshini abadala abanobulukhuni obungonelanga okanye iimeko zokusetyenzwa kwespan enkulu.
5. Izinto eziluncedo zokulungisa iindawo ezinodonga olucekethekileyo: Amandla eradial amancinci ngokugqithisileyo enza ukuba isisiki esikhulu sokusila sibe lolona khetho lufanelekileyo lokulungisa iindawo ezinodonga olucekethekileyo kunye nezikhubazeke ngokulula (ezinje ngezakheko ze-aerospace, amalungu omzimba wemoto). I-deformation ye-workpiece iyancipha ngama-60% -70% xa kuthelekiswa nokusila kwendabuko.
Ireferensi yeeparamitha zokusetyenzwa kwefeed ephezulu yokusika:
Xa usebenzisa i-high feed milling cutter enobubanzi obuyi-50mm kwaye ixhotyiswe ngeencakuba ezi-5 kumatshini we-P20 isixhobo sentsimbi (HRC30):
Isantya somjikelo: 1,200 rpm
Ireyithi yokutya: 4,200 mm / min
Ubunzulu bokusika kwe-Axial: 1.2mm
Ubunzulu bokusika iRadial: 25mm (ukutya okusecaleni)
Izinga lokususa isinyithi: Ukuya kuthi ga kwi-126 cm³/min
IV. Isishwankathelo
Umsiki wokusila ukutya okuphezulu ayisosixhobo nje; imele ingqiqo yoqhubekeko oluphambili. Ngokuyila ngobuchule koomatshini, iguqula izinto ezingeloncedo zokusika amandla zibe ziinzuzo, ukufikelela kwindibaniselwano egqibeleleyo yesantya esiphezulu, ukusebenza kakuhle okuphezulu, kunye nokucokiseka okuphezulu. Kumashishini okulungisa oomatshini ajongene noxinzelelo lokwandisa ukusebenza kakuhle kunye nokuhlangabezana neemfuno zokusetyenzwa komgangatho ophezulu, usetyenziso olunengqiqo lwetekhnoloji yentloko yokugaya ukutya okukhawulezayo ngokungathandabuzekiyo lukhetho lobuchule lokuphucula ukhuphiswano.
Ngophuhliso oluqhubekayo lwetekhnoloji ye-CNC, izixhobo zesixhobo kunye nesoftware ye-CAM, itekhnoloji yokugaya ukutya ngokukhawuleza iya kuqhubeka iguquka, ibonelela ngenkxaso eyomeleleyo yobugcisa botshintsho olukrelekrele kunye nokuphuculwa koshishino lokuvelisa. Ngoko nangoko faka intloko yokusila ekhawulezayo yokusila kwinkqubo yakho yemveliso kwaye ube namava oguqulo lwesiphumo sokusebenza kakuhle!
