Iimfuno zezixhobo zomatshini we-CNC kwizinto zesixhobo
Ubunzima obuphezulu kunye nokumelana nokunxiba
Ubunzima becandelo lokusika isixhobo kufuneka libe phezulu kunobunzima bezinto zokusebenza. Ukuphakama kobunzima besixhobo sesixhobo, bhetele ukuxhathisa kwayo ukunxiba. Ukuqina kwesixhobo kwiqondo lobushushu begumbi kuya kuba ngaphezulu kwe-HRC62. Ubunzima bunokuba phezulu kunobo buqhelekileyoCNC Machining iindawo.
Amandla aneleyo kunye nokuqina
Isixhobo sithwala uxinzelelo oluhle kakhulu kwinkqubo yokusika ngokugqithiseleyo. Ngamanye amaxesha, isebenza phantsi kweempembelelo kunye neemeko zokungcangcazela. Ukuthintela isixhobo ekuqhekekeni nasekuphuleni, izixhobo zesixhobo kufuneka zibe namandla okwaneleyo kunye nokuqina. Ngokubanzi, amandla okugoba asetyenziselwa ukumela amandla esixhobo, kwaye ixabiso lempembelelo lisetyenziselwa ukuchaza ukuqina kwesixhobo sesixhobo.
ukumelana nobushushu obuphezulu
Ukumelana nobushushu kubhekiselele ekusebenzeni kwezixhobo zokusebenza ukugcina ubulukhuni, ukuxhathisa ukunxiba, amandla, kunye nokuqina phantsi kobushushu obuphezulu. Isalathiso esikhokelayo sokulinganisa ukusebenza kokusika kwezixhobo zesixhobo. Le ntsebenzo ikwabizwa ngokuba bubulukhuni obubomvu bezixhobo zesixhobo.
Ukuqhuba kakuhle kwe-thermal
I-thermal conductivity ye-thermal material yesixhobo, ukushisa okungaphezulu kudluliselwa kwisixhobo, okulungele ukunciphisa ukushisa kwesixhobo kunye nokuphucula ukuqina kwayo.
Ukuqhubekeka kakuhle
Ukuququzelela ukusetyenzwa kwesixhobo kunye nokuveliswa, izixhobo zesixhobo kufuneka zibe neempawu ezintle zokucwangcisa, ezifana nokubumba, ukuqengqeleka, ukuwelda, ukusika kunye nokusila, iipropati zonyango lobushushu, kunye neempawu zeplastiki zokushisa eziphezulu zezixhobo zesixhobo. I-carbide ene-cemented kunye nezixhobo ze-ceramic izixhobo nazo zifuna i-sintering efanelekileyo kunye neempawu zokwenza uxinzelelo.
Uhlobo lwezixhobo zesixhobo
intsimbi enesantya esiphezulu
Intsimbi yesantya esiphezulu sisixhobo sensimbi esine-alloy esakhiwe yi-W, Cr, Mo, kunye nezinye izinto ze-alloy. Inozinzo oluphezulu lwe-thermal, amandla, ukuqina, kunye neqondo elithile lobunzima kunye nokumelana nokunxiba, ngoko ifanelekile ukusetyenzwa kwe-non-ferrnonferrous kunye nezixhobo ezahlukeneyo zetsimbi. Ukongeza, ngenxa yetekhnoloji yokucubungula isandi, ilungele ukwenza izixhobo zokwenza izixhobo ezintsonkothileyo, ngakumbi isinyithi sesinyithi esinesantya esiphezulu, esineempawu ze-anisotropic mechanical kunye nokunciphisa ukucima ukuguqulwa; ifanelekile ukwenza izinto ezichanekileyo kunye nezixhobo zokubumba ezintsonkothileyo.
I-alloy eqinile
I-carbide enesamente inobunzima obuphezulu kunye nokumelana nokunxiba. Xa usikaCNC ukuguqula iindawo, ukusebenza kwayo kungcono kunentsimbi yesantya esiphezulu. Ukuqina kwayo kuphindaphindwe kaninzi ukuya kwamashumi aphindwe kabini oko kwentsimbi enesantya esiphezulu, kodwa ukuqina kwempembelelo yayo kubi. Ngenxa yokusebenza kwayo okugqwesileyo kokusika, isetyenziswa ngokubanzi njengesixhobo sesixhobo.
Ukwahlula kunye nokumakishwa kwee-carbides ezine-cemented kwizixhobo zokusika
Iblade ecandiweyo
I-1) Izinto zokugqoka zendlela ye-CVD yi-TiC, eyandisa ukuqina kwezixhobo ze-carbide ze-cemented ngamaxesha angama-1-3. Ubunzima bokugquma: Umphetho wokusika awucacanga kwaye ulungele ukuphucula ubomi besantya.
I-2) Izinto zokugqoka ze-PVD indlela yokubeka umphunga womzimba yi-TiN, i-TiAlN, kunye ne-Ti (C, N), ephucula ukuqina kwezixhobo ze-carbide ze-cemented ngamaxesha angama-2-10. Ukwaleka obhityileyo; Uhlangothi olubukhali; Iluncedo ekunciphiseni amandla okusika.
★ Ubuninzi bobukhulu bengubo ≤ 16um
CBN kunye nePCD
I-Cubic boron nitride (CBN) Ukuqina kunye ne-thermal conductivity ye-cubic boron nitride (CBN) ingaphantsi kwedayimane, kwaye inozinzo oluphezulu lwe-thermal kunye neekhemikhali. Ke ngoko, ilungele ukwenza intsimbi eqinile, intsimbi eqinile, i-superalloy, kunye ne-samente carbide.
Idayimani yePolycrystalline (PCD) Xa i-PCD isetyenziswe njengesixhobo sokusika, i-sintered kwi-semented carbide substrate. Inokugqiba ukumelana nokunxiba, ubunzima obuphezulu, i-non-metallic, kunye ne-nonferrononferrousaterials ezifana ne-cemented carbide, i-ceramics, kunye ne-silicon ephezulu ye-aluminium alloy.

isantya sokusika
Ifomula yokubala yesantya sokusika Vc:
Kwifomula:
D - i-diameter ejikelezayo ye-workpiece okanye i-tooltip, iyunithi: mm
N - isantya esijikelezayo somsebenzi okanye isixhobo, iyunithi: r/min
Isantya soMsonto woMachining ngeLathe eqhelekileyo
Isantya sokusonta n sokujika intambo. Xa usika intambo, isantya sokusonta selathe sichatshazelwa zizinto ezininzi, ezinjengobungakanani bepitch yentambo (okanye ilothe) yesixhobo sokusebenza, iimpawu zokuphakamisa nokwehliswa kwemoto yokuqhuba, kunye nesantya sokudibanisa intambo. Ke ngoko, umahluko othile ukhona kwisantya sokusonta kumsonto wokujika weenkqubo ezahlukeneyo zeCNC. Oku kulandelayo yifomula yokubala isantya sokusonta xa ujika imisonto kwiileyile ze-CNC ngokubanzi:
Kwifomula:
I-P - i-pitch pitch okanye i-lead ye-workpiece thread, iyunithi: mm.
K - i-inshurensi yomlinganiso, ngokubanzi 80.
Ukubalwa ubunzulu feed nganye ukuze machining thread
Inani leendlela zesixhobo sokuthunga
1) Umatshini orhabaxa
Ifomula yokubala enobungqina bokutya komatshini orhabaxa: f rough=0.5 R
Apho: R ------ incam yesixhobo arc radius mm
F ------ rough Machining isixhobo feed mm
2) Ukugqiba
Kwifomula: Rt ------ ubunzulu becontour µ m
F ------ Isantya sokutya mm/r
r ε ------ Irediyo yesixhobo se-arc mm
Ukwahlula ukujikajika okurhabaxa kunye nokugqiba ngokwesantya sokutya kunye ne-chip-breaking groove
F ≥ 0.36 machining rough
0.36 ＞ f ≥ 0.17 isiqingatha sokugqiba
F ＜ 0.17 ukugqiba machining
Ayisiyonto ye-blade kodwa i-chip-breaking groove echaphazela i-rough kunye ne-machining egqityiweyo ye-blade. I-edge yokusika ibukhali ukuba i-chamfer ingaphantsi kwe-40um.
