Ukukhethwa kwe-Angle: kusukela ezicini zesizukulwane sokusika ukushisa nokushisa kokushisa, wathi ngaphambi kokwandisa i-Angle kunganciphisa isizukulwane sokusika ukushisa, ukushisa okusika akukona okuphezulu, kodwa ngenxa yokushisa kokushisa kwamathuluzi okusika i-rake Angle ivolumu enkulu kakhulu. kuncipha, futhi izinga lokushisa lokusika liyenyuka.
Ukunciphisa i-Angle ye-rake kungathuthukisa isimo sokupholisa samathuluzi wokusika, izinga lokushisa lokusika linganciphisa, kodwa ngaphambi kokuba i-Angle incane kakhulu, i-deformation yokusika, ukusika ukushisa akulula.
Ukuzijwayeza kubonisa ukuthi uphondo lwangaphambili hamba = 15 ° ~ 20 ° lufaneleka kakhulu.
I-Angle yokuzikhethela: ngemuva komshini onzima, ithuluzi lokusika eliqinile lidinga ukusika kwe-blade ukuqina kuphezulu, kufanele uthathe ngemuva kwe-Angle encane;
Qeda imishini, ukuguga kwethuluzi kwenzeka ikakhulukazi endaweni yokusika kanye nommese, ngoba insimbi engagqwali kulula ukuvela ukuqina kwezinto ezibonakalayo, kulandelwa ukungqubuzana kobuso bommese ukuze kube nomthelela omkhulu kukhwalithi ye-machining surface kanye nokugqoka kwamathuluzi, ukucubungula okunengqondo. I-angle kufanele ibe: ngemuva kwensimbi engagqwali ye-austenitic (
Ngaphansi kuka-185 hb)
, kulandele i-Engela inketho 6 ° ~ 8 °;
Ukucubungula kanye nensimbi engagqwali ye-martensitic (
Ngaphezu kuka-250 hb)
, bese uthatha 6 - I-engeli
8.
Ukucubungula kanye nensimbi engagqwali ye-martensitic (
Ngaphansi kuka-250 hb)
, ilandelwa i-Angle kufanele ibe ngu-6 ° ~ 10 °.
I-Blade Angle yokuzikhethela: usayizi we-Angle ye-blade nesiqondiso, thola isiqondiso sokugeleza kwe-chip, ukukhetha okunengqondo i-ls blade Angle, ngokuvamile thatha -
Kunconywa ukuthi ufinyelele ku-10 ° ~ 20 °.
Ku-trace essence imoto eyi-cylindrical, izimbobo ezinhle, izinga lendiza, amathuluzi okusika okuthambekela okukhulu kufanele kwamukelwe: kufanele kuthathe ls45 ° ~ 75 °.
