Umu ndi momwe mungasankhire pang'ono potengera ma bits atatu: zakuthupi, zokutira ndi mawonekedwe a geometric.
01, momwe mungasankhire zinthu za kubowola
Zida zitha kugawidwa m'magulu atatu: chitsulo chothamanga kwambiri, chitsulo chothamanga kwambiri cha cobalt ndi carbide yolimba.
Chitsulo Chothamanga Kwambiri (HSS) :
Chitsulo chothamanga kwambiri chakhala chikugwiritsidwa ntchito ngati chida chodulira kwa zaka zoposa zana kuyambira 1910. Ndiwogwiritsidwa ntchito kwambiri komanso mtengo wotsika mtengo wodula zida zomwe zilipo masiku ano.Zitsulo zachitsulo zothamanga kwambiri zitha kugwiritsidwa ntchito pobowola pamanja komanso m'malo okhazikika monga makina osindikizira.Chifukwa chinanso cha kulimba kwa zitsulo zothamanga kwambiri n’chakuti zida zake, zomwe zimatha kukalika mobwerezabwereza, n’zotsika mtengo moti sizingangogwiritsidwa ntchito ngati zobowola komanso zotembenuza.
Cobalt High Speed Steel (HSSE):
Cobalt yokhala ndi chitsulo chothamanga kwambiri imakhala ndi kuuma bwino komanso kuuma kofiira kuposa chitsulo chothamanga kwambiri.Kuwonjezeka kwa kuuma kumawonjezeranso kukana kuvala, koma nthawi yomweyo, kulimba kwina kumaperekedwa nsembe.Monga chitsulo chothamanga kwambiri, amatha kupukutidwa kuti azigwiritsa ntchito bwino.
CARBIDE:
Cemented carbide ndi chinthu chophatikizika chazitsulo.Mwa iwo, tungsten carbide imagwiritsidwa ntchito ngati matrix, ndipo zida zina zazinthu zina zimagwiritsidwa ntchito ngati zomatira kudzera munjira zingapo zovuta monga kukanikiza kwa isostatic kwa sintering.Mu kuuma, kuuma kofiira, kukana kuvala ndi mbali zina poyerekeza ndi zitsulo zothamanga kwambiri, pali kusintha kwakukulu, koma mtengo wa chida cha carbide ndi wokwera mtengo kwambiri kuposa chitsulo chothamanga kwambiri.Cemented carbide mu moyo chida ndi processing liwiro kuposa zida m'mbuyomu zida ubwino zambiri, mu mobwerezabwereza akupera chida, kufunika kwa akatswiri akupera zida.
02, momwe mungasankhire zokutira pang'ono
Chophimbacho chikhoza kugawidwa m'magulu 5 otsatirawa malinga ndi momwe amagwiritsira ntchito.
Zosatsekedwa: Zida zodulira zosavala ndizotsika mtengo kwambiri, zomwe nthawi zambiri zimagwiritsidwa ntchito pokonza aloyi ya aluminiyamu, chitsulo chochepa cha carbon ndi zinthu zina zofewa.
Kupaka kwa okusayidi wakuda: zokutira za okosijeni zimatha kupereka bwino kuposa kutsekemera kwa zida zosavundikira, kumakhala ndi kukana kwa okosijeni bwino komanso kukana kutentha, ndipo kumatha kusintha moyo wautumiki wopitilira 50%.
Titaniyamu nitride ❖ kuyanika: Titaniyamu nitride ndi ambiri ❖ kuyanika zakuthupi, si oyenera pokonza kuuma mkulu ndi mkulu processing zipangizo kutentha.
Titaniyamu carbon nitride zokutira: Titaniyamu carbon nitride amapangidwa kuchokera titaniyamu nitride, ali ndi kutentha kukana ndi kuvala kukana, nthawi zambiri wofiirira kapena buluu.Amagwiritsidwa ntchito m'ma workshop a Haas popanga zida zachitsulo.
Kupaka kwa aluminium nitride titaniyamu: zokutira aluminium nitride titaniyamu kuposa zonse zomwe zili pamwambazi ndizosamva kutentha, kotero zimatha kugwiritsidwa ntchito pamalo odula kwambiri.Monga processing superalloys.Ndiwoyeneranso kukonzanso zitsulo ndi zitsulo zosapanga dzimbiri, koma chifukwa zili ndi zinthu zotayidwa, zotsatira za mankhwala zidzachitika pokonza aluminiyamu, choncho m'pofunika kupewa kukonza zipangizo zomwe zili ndi aluminium.
Nthawi zambiri, kubowola kokhala ndi cobalt ndi titaniyamu carbonitride kapena titaniyamu nitride zokutira ndi njira yochepetsera ndalama.
03. Makhalidwe a geometric a kubowola pang'ono
Zithunzi za geometric zitha kugawidwa m'magawo atatu awa:
Kutalika
Chiŵerengero cha kutalika kwa m'mimba mwake chimatchedwa kuwirikiza kawiri, ndipo chocheperako m'mimba mwake, chimakhala bwino kwambiri.Kusankha pang'ono ndi utali woyenerera wa m'mphepete mwa kuchotsa chip ndi kutalika kwaufupi kwambiri kungathe kusintha makina okhwima, potero kuwonjezera moyo wa zida.Kutalika kosakwanira m'mphepete kumatha kuwononga pobowola.
Kubowola nsonga Angle
Pobowola Angle ya 118 ° mwina ndiyomwe imapezeka kwambiri pamakina ndipo imagwiritsidwa ntchito kwambiri pazitsulo zofewa monga zitsulo zofatsa ndi aluminiyamu.Mapangidwe a Anglewa nthawi zambiri samangongoyang'ana okha, zomwe zikutanthauza kuti dzenje lolowera liyenera kupangidwa kaye.The 135 ° kubowola nsonga Angle nthawi zambiri kudzikonda, zomwe zimapulumutsa nthawi yochuluka pochotsa kufunikira kokonza dzenje limodzi lokhazikika.
Spiral Angle
A 30 ° spiral Angle ndi chisankho chabwino pazinthu zambiri.Komabe, m'malo omwe ma cuttings amachotsedwa bwino komanso m'mphepete mwake ndi amphamvu, pang'ono ndi ngodya yaing'ono yozungulira ikhoza kusankhidwa.Pazinthu zogwirira ntchito molimbika monga chitsulo chosapanga dzimbiri, chojambula chokhala ndi Angle yokulirapo chingagwiritsidwe ntchito kusamutsa torque.
