Dab tsi yog Cov Ntsiab Lus Tseem Ceeb Ntawm Qhov Sib Nrauj Ua Tshuab?

Qhov thiaj li-hu ua qhov sib sib zog nqus qhov machining yog ib lub qhov ntev rau lub qhov taub qhov sib piv yog ntau dua 6. Nyob rau hauv lub qhov sib sib zog nqus machining, qhov tob ratio L / d Ntau tshaj los yog sib npaug rau 100 nyob rau hauv feem ntau ntawm lub qhov sib sib zog nqus ua. Xws li lub tog raj kheej lub qhov, lub axial roj qhov ntawm lub ncej, hollow spindle qhov thiab hydraulic valve qhov thiab lwm yam.

Qee qhov ntawm cov qhov no xav tau kev ua haujlwm siab thiab qhov zoo, thiab qee qhov ntawm cov khoom siv tau ua haujlwm tsis zoo, uas feem ntau dhau los ua teeb meem loj hauv kev tsim khoom.

(1) Kev taw qhia thiab qhov nruab nrab qhov teeb meem

① Pre-drill the tapered centering hole, that is, first drill a tapered pit with a small apex angle (2=90 degree -100 degree ), a large diameter short twist drill or a center drill, and then drill a hole with a drill of the required size.

② Sharpen the drill bit, make the two main cutting edges as symmetrical as possible, so that the radial cutting forces cancel each other and reduce the radial deviation.

③ Regarding large-diameter holes (>30mm), txoj kev drilling ob zaug ntawm lub tshuab drilling feem ntau yog siv, uas yog, qhov thib ob drilling yog ua raws li qhov yuav tsum tau ua. Txij li thaum lub chisel hniav yog siv rau kev ua hauj lwm, lub laum me ntsis yuav tsis zoo li twisted. . Hais txog qhov me me thiab qhov tob tob, txhawm rau tiv thaiv lub axis ntawm lub qhov los ntawm kev sib txawv, xyaum lawv ntawm lub tshuab dhos kom ntau li ntau tau.

(2) Cov teeb meem cua txias

Hauv kev tsim khoom tiag tiag, kev ua kom txias txias lossis txias txias tuaj yeem siv raws li cov txheej txheem ua tiav kom paub tseeb tias qhov txias txias. Hauv kev ua haujlwm zoo tib yam, segmented drilling feem ntau yog siv, thiab cov txheej txheem ntawm kev taw qhia raws sijhawm yog siv los ua kom txias lub laum me ntsis thiab qhov chaw drilling. Tsis tas li ntawd, cov nyhuv txias tuaj yeem txhim kho los ntawm cov qauv ntawm cov laum me ntsis.

(3) Chip tshem tawm teeb meem

Ordinary drilling processing feem ntau siv txoj kev tawm ntawm lub sijhawm kom tshem tawm cov chips; Hauv kev sib sib zog nqus qhov ua tiav, cov qauv ntawm cov laum me ntsis thiab cov ntsuas cua txias tau ua ke, thiab cov chips raug yuam tawm los ntawm lub siab txias. Qhib nti grooves ntawm lub ntsiab txiav ntug, txo qhov dav txiav, ua rau cov chips yooj yim rau curl, kuj yog ib txoj hauv kev los txhim kho cov nyhuv ntawm nti tshem tawm.
