Zithini iimfuno zezixhobo ezingenazilutho ezingenalo?

1. Khetha iiparamitha zejometri yesixhobo

Xa intsimbi ehamba intsimbi engenasitali, ijometri yenxalenye yokusika isixhobo kufuneka ithathelwe ingqalelo kukhetho lwe-rake andle. Xa ukhetha i-angle ye-rake, izinto ezinje ngeprofayili yeflethi, ubukho okanye ukungabikho komntu oshukumayo kunye ne-angle elungileyo nengalunganga yotyekelo lweBlade kufuneka luqwalaselwe. Nokuba sesi sixhobo, i-angle enkulu ye-rake kufuneka isetyenziswe xa i-teain yentsimbi. Ukonyusa i-angle yesixhobo inokukunciphisa ukuxhathiswa okhuphisana ne-Chip ukusika kunye nokucoca. Ukukhethwa kwengcaciso ye-engle ayingqongqo kakhulu, kodwa ayifanele ibe mncinci kakhulu. Ukuba i-angle icace incinci kakhulu, iya kubangela imbambano enkulu kunye nomphezulu womsebenzi, ibetha ubungqingqwa boomatshini bokwakhiwa komhlaba kunye nokukhawulezisa izixhobo. Kwaye ngenxa yengxabano eyomeleleyo, isiphumo sokukhula komgangatho wentsimbi engenanto kuyaphuculwa; Isixhobo se-cicle ifanele ukuba sikhulu kakhulu, sikhulu kakhulu, ukuze i-angile yesixhobo incitshisiwe, amandla omda osikiweyo ancitshiswa, kwaye ukusetyenziswa kwesixhobo kuyakhawuleziswa. Ngokubanzi, i-engile yokunceda ifanele ibe nkulu kakhulu kunexesha le-carbon yekhabhoni eqhelekileyo.

Ukukhetha i-angle ye-rake kwinkalo yokusika isizukulwana sobushushu kunye nokuchithwa kobushushu, kwaye i-rake angle inkulu kakhulu, kodwa iqondo lokungatshisi liya kuhlaselwa. Iphakanyisiwe. Ukunciphisa i-angle ye-rake kunokuphucula iimeko zokusebenzela ubushushu kwintloko yesikithi, kwaye amaqondo obushushu anokuncipha, kodwa ukuba i-rake angle incinci kakhulu, kwaye ubushushu obuveliswe ngokulula akuyi kudaniswa ngokulula. Ukuziqhelanisa kubonisa ukuba i-rake angle hamba = i-15 ° -20 ° yeyona ifanelekileyo.

Xa ukhetha i-angle yokucoca umatshini oqengqelekayo, amandla okusika izixhobo ezinamandla zokusika kufuneka ukuphakama, ke i-angle encinci kufuneka ikhethwe; Ngexesha lokugqiba, isixhobo sinxiba ikakhulu kwindawo yokucheba kunye nomphezulu weflethi. Intsimbi engenasimo, umbandela oqhele ukusebenza nzima, unempembelelo enkulu kumgangatho womhlaba kunye nokunxiba kwesixhobo okubangelwa kukungqubana komgangatho. I-angle yokunceda efanelekileyo kufuneka ibe: Kwintsimbi engenasibala (ngezantsi kwe-185Hb), iAngle yokuNgenisa inokuba i-6 ° - i-8 °; Ukuqhubela phambili intsimbi engenasithulo (ngaphezulu kwe-250Hb), i-angle icace i-6 ° 88 ° 2 ° Kwintsimbi ye-Martiaticic (ngezantsi kwe-250hb), i-angle icace i-6 ° -10

Ukhetho lwe-bladel angle ubungakanani kunye nolwalathiso lwe-blade i-angle ichonge indlela yokuhamba kwe-chip. Ukhetho olufanelekileyo lwe-blade i-ls i-LS idla -10 ° -20 °. Izixhobo ezinkulu zeBlades kufuneka zisetyenziswe xa kugqitywe umda we-microning, iingcango ezihamba kakuhle, kunye neenqwelomoya ezihle, kunye neendiza ezihle: I-LS45 ° I-775 ° isetyenzisiwe.

2. Ukukhetha izixhobo ezizasetyenziswa

Xa iqhubela phambili intsimbi engenasitali, umtya wesixhobo kufuneka abe namandla awoneleyo kunye nobungqongqo ngenxa yamandla amakhulu okusika ukunqanda ukuncokola kunye nokudakumba ngexesha lenkqubo yokusika. Oku kufuna ukuba kukhethwe indawo enkulu yendawo enamacandelo ecandelo, kunye nokusetyenziswa kwezinto ezinamandla okwenza umnini-mbi, njengokusetyenziswa kwentsimbi ecinywe kunye ne-45 yentsimbi okanye i-50 yentsimbi.

Izinto ezifunekayo kwinxalenye yokusika kwesixhobo xa kusenziwa intsimbi engenasitali, impahla yenxalenye yokusika isixhobo inyanzelekile ukuba ichithe ukusebenza okuphezulu kunye nokugcina intsebenzo ephantsi. Okwangoku izixhobo ezisetyenziswayo zezi: intsimbi enesikhafu esiphezulu kunye ne-carbide ye-carbide. Kungenxa yokuba isitya esinesantya esiphezulu sinokugcina kuphela ukusebenza kwe-600 ° C, ayifanelekanga ekunqumeni ngesantya esiphezulu, kodwa ilungele kuphela intsimbi engenasitali engenasiseko sezintya. Kungenxa yokuba i-carbide ye-carbide inobuchasi obufanelekileyo kwaye inxibe ukuchasana nentsimbi enesidima esiphakamileyo, izixhobo ezenziwe ngezinto eziziintloko ze-carbide ze-subbide zilungele kakhulu intsimbi engenasiseko.

I-carbide yamandla yahlulwe yangamacandelo amabini: I-Tungsten-Cobalt Allow (yg) kunye ne-tungsten-cobalt-titanium alloy (yt). I-Tungsten-Cobalt Alloys inobunzima obulungileyo. Izixhobo ezenziweyo zinokusebenzisa i-angle enkulu ye-rake kunye nomphetho obukhali wokugaya. Iitshipsi kulula ukuyigculela ngexesha lenkqubo yokusika, kwaye ukusikwa yibrisk. Iitshipsi azilula ukubambelela kwesi sixhobo. Kule meko, kufanelekile ukuqhubela phambili kwentsimbi engenasibala kunye ne-tungsten-cobalt alloy. Ingakumbi kuMatshini oQilekileyo kunye nokuThunyelwa kweXesha lokuNgena ngeViberes enkulu, i-tungsten-cobalt ye-tungtsty allotty kufuneka isetyenziswe. Akunzima kwaye brittle njenge-tungsten-cobalt-titanium, akukho lula ukulilola, kwaye kulula ukuvumba. I-Tungsten-Cobatanium-Titanium ye-titanium inobunzima obubomvu obungcono kwaye iphazamise ngakumbi kune-tungsten-cobalt ye-tungsten-cobalt phantsi kweemeko zobushushu obuphezulu, kodwa ayixhaleli ifuthe kunye nokuziqhelanisa ne-stainess yentsimbi entle.

Ukusebenza kokusika kwezinto ezibonakalayo kunxulumene nokuqina kunye nemveliso yesixhobo, kunye nokunikezelwa kwesixhobo sesixhobo kuchaphazela ukwenziwa kwemveliso kunye nomgangatho obukhali wesixhobo semveliso ngokwayo. Kucetyiswa ukukhetha izixhobo zezixhobo ezinobunzima obuphezulu, ukunganyangeki kakuhle kunye nobunzima, ukuba ungasebenzisi i-yt i-staide ye-staide, i-titanium (i-titanium (i-TITRE) kwi-IT-Cheed Speed ​​I-YARBIDE i-YARBIDE i Ubumbano, i-chips ingathatha lula i-TI kwi-alloy, ekhuthaza ukusetyenziswa kwesixhobo esandayo. Ukuziqhelanisa nokuziqhelanisa kubonisa ukuba ukusetyenziswa kwe-YG532, yg813 kunye ne-YW2 yamabakala amathathu ezixhobo ukuze kuqhubeke intsimbi engenasitali inesiphumo sokusebenza kakuhle

I-3. Ukukhetha isixa sokusika

Ukwenzela ukucinezela umda owakhelweyo kunye nesikali se-spurs kunye nokuphucula umgangatho womhlaba, xa kusenziwa isantya se-carbide, i-SEATE i-APREY i-AP = 0.15mm, kunye ne-0.15mm / r.

I-4. IIMFUNO ZOBUCHULE BENKCAZO YABASEBENZI

Ukuphuculwa komphezulu wokugqibela kwenxalenye yokusika kwenxalenye yesixhobo kunokunciphisa ukumelana xa iitshipsi zityhutyha kwaye ziphucule ukuqina kwesixhobo. Xa kuthelekiswa neSoftware eqhelekileyo ye-carbon, xa iqhubela phambili intsimbi engenasitali, isixa esisikiweyo kufuneka sincitshiswe ngokufanelekileyo sinxibe izixhobo zokunxiba; Kwangelo xesha, ukupholisa okufanelekileyo kunye nokuthambisa amanzi kufuneka khethwe ukunciphisa ubushushu obukhulu kunye nokusika amandla ngexesha lokusika, kunye nokwandisa ubomi benkonzo.
