Ngemva kokukhetha isisiki, abantu abaningi abacaci ekusetheni isivinini sokusika, zungezisa isivinini kanye nokujula kokusika.Lokhu kuyingozi kakhulu, kuzobangela ukuphuka kwe-cutter, izinto ezibonakalayo ziyancibilika noma zishise.Ingabe ikhona indlela yokubala?Impendulo ithi yebo!
1. Ijubane lokusika:
Isivinini sokusika sisho isivinini esisheshayo sephuzu elikhethiwe ethuluzini elihlobene nendawo ehambisanayo ku-workpiece.
Vc=πDN/1000
Vc- isivinini sokusika, Iyunithi: m/min
N- isivinini sokuzungezisa, Iyunithi: r/min
D- Umsiki ububanzi, Iyunithi: mm
Isivinini sokusika sithintwa izinto ezifana nempahla yamathuluzi, impahla yokusebenza, ukuqina kwezingxenye zamathuluzi omshini, noketshezi lokusika.Imvamisa isivinini esiphansi sokusika sivame ukusetshenziselwa umshini wezinsimbi eziqinile noma ama-ductile, okusika okunamandla kodwa kunganciphisa ukuguga kwamathuluzi nokwelula impilo yamathuluzi.Isivinini sokusika esiphezulu sivame ukusetshenziselwa umshini izinto ezithambile ukuze kutholwe isiphetho esingcono.Isivinini sokusika esiphezulu singasetshenziswa kusisiki esinobubanzi obuncane esisetshenziselwa ukwenza ukusika okuncane ezintweni zokusebenza eziphukayo noma izingxenye ezinembayo.Isibonelo, isivinini sokugaya sesisiki sensimbi esinesivinini esikhulu singu-91~244m/min nge-aluminium, kanye no-20~40m/min ngethusi.
2.Isivinini sokuphakelayo esisikayo:
Isivinini sokuphakelayo singesinye isici esibaluleke ngokulinganayo esinquma umsebenzi womshini ophephile futhi ophumelelayo.Isho isivinini sokuhamba esihlobene phakathi kwezinto zokusebenza nethuluzi.Kuma-multi-tooth milling cutters, njengoba izinyo ngalinye libamba iqhaza emsebenzini wokusika, ubukhulu be-workpiece okufanele inqunywe buncike kuzinga lokuphakelayo.Ubukhulu bokusikwa bungathinta impilo yomsiki wokugaya.Ngakho-ke amazinga okuphakela ngokweqile angabangela unqenqema lokusika noma ithuluzi liphuke.
Vf = Fz *Z * N
Isivinini se-Vf-feed, Iyunithi mm/min
Ukuhlanganyela kwe-Fz-feed，Iyunithi mm/r
Z-Cutter amazinyo
Isivinini sokuzungezisa se-N-Cutter，Iyunithi r/min
Kusukela kufomula engenhla, sidinga ukwazi kuphela ukubandakanyeka kokuphakelayo (inani lokusika) lezinyo ngalinye kanye nesivinini sokuzungezisa esingase sisuse isivinini sokuphakelayo.Ngamanye amazwi, ukwazi ukuzibandakanya kokuphakelayo kanye nesivinini sokuphakela ngezinyo ngalinye, isivinini sokujikeleza singabalwa kalula.
Isibonelo, i-high-speed steel milling cutter, lapho ububanzi bokusika buyi-6 mm, okuphakelayo ngezinyo ngalinye:
I-Aluminium 0.051;Ithusi 0.051;I-Cast Iron 0.025;Insimbi Engagqwali 0.025
3.Ukujula kokusika:
Isici sesithathu ukujula kokusika.Inqunyelwe inani lokusika le-workpiece, amandla ajikelezayo e-CNC, i-cutter kanye nokuqina kwethuluzi lomshini.Ngokuvamile, ukujula kokusikwa komshini wokugaya insimbi akufanele kudlule uhhafu wobubanzi bokusika.Ukusika izinsimbi ezithambile, ukujula kokusika kungaba kukhudlwana.Isigayo sokugcina kufanele sibe bukhali futhi sisebenze ngokugxilile ne-end chuck, futhi sibe ne-overhang encane ngangokunokwenzeka lapho ithuluzi lifakiwe.
I-Xiamen Ruicheng Industrial Design Co., Ltd inolwazi olucebile ku-CNC, zizwe ukhululekile ukusifinyelela uma unesidingo!
