tātai tātai miro

E mohio ana te katoa ki te miro. Hei hoa mahi i roto i te umanga whakangao, he maha nga wa e hiahia ana matou ki te taapiri i nga miro kia rite ki nga hiahia o nga kaihoko i te wa e tukatuka ana i nga taputapu taputapu penei i teNga waahanga miihini CNC, Nga waahanga hurihuri CNCaNga waahanga mira CNC.

1. He aha te miro?
Ko te miro he helix kua tapahia ki tetahi mea mahi mai i waho, mai i roto ranei. Ko nga mahi matua o nga miro ko:
1. Hangaia he hononga miihini ma te whakakotahi i nga hua miro o roto me nga hua miro o waho.
2. Whakawhiti i te nekehanga ma te huri i te nekehanga hurihuri ki te nekehanga raina me te huri ke.
3. Tikina nga painga miihini.
2. Te kōtaha miro me ngā kupu
Ko te kōtaha miro e whakatau ana i te āhuahanga o te miro, tae atu ki te diameter o te mea mahi (nga taima nui, pitch, me te iti); koki kōtaha miro; ware me te koki helix.
1. Nga kupu miro
① Raro: Ko te mata o raro e hono ana i nga taha miro e rua.
② taha: te mata taha miro e hono ana i te tihi me te raro o te niho.
③Crest: Ko te mata o runga e hono ana i nga taha e rua.
P = pitch, mm, miro ranei mo ia inihi (tpi)
ß = koki kōtaha
ϕ = koki helix miro
d = te diameter nui o te miro o waho
D = te diameter nui o te miro o roto
d1 = iti te diameter o te miro o waho
D1 = He iti te diameter o te miro o roto
d2 = te diameter o te miro o waho
D2 = te diameter pitch miro o roto
Te diameter o te papa, d2/D2
Te diameter whai hua o te miro. Tata ki te haurua i waenga i nga diameter nui me te iti.

Ko te ahuahanga o te miro kei runga i te diameter pitch miro (d, D) me te pitch (P): te tawhiti axial i te taha o te miro i runga i te mea mahi mai i tetahi ira i runga i te whaarangi ki te waahi e whai ake nei. Ka kitea hoki tenei he tapatoru e hipa ana i te taonga mahi.
vc = tere tapahi (m/min)
ap = hohonu miro katoa (mm)
moe = hohonu miro katoa (mm)
tpi = miro mo ia inihi
Whangai = pitch
