1. Txheeb xyuas qhov ceev nrawm: Lub nrawm noj yog feem ntau raws li kev paub. Cov lus hais ntau, feem ntau nws yog 0.08-0.12mm / RPM lossis 0.6-1.0mm / SEC. Cov kev pub ceev yog qhov tseem ceeb ua rau lub tshuab nruas


2. Txoj Haujlwm: Ntaus rau qee qhov taw tes hauv nruab nrab qhov chaw txhaws qhov yuav tsum tau tho lossis kos" hla" kab nrog lub koob txhaj hlau kom paub tseeb tias qhov tseeb ntawm drilling txoj hauj lwm. Nco tseg: thaum lub chaw chisel yog siv los teeb tsa txoj haujlwm, thov nco ntsoov tias lub chisel nruab nrab yog txiav mus rau sab saum npoo ntawm qhov chaw ua haujlwm kom tsis txhob cuam tshuam cov dej paug ntawm qhov txiav tawm cov tub ntxhais.


3. Pib xyaum: Thov kho qhov tsim nyog ceev, thiab paub tseeb tias hauv qab ntawm lub rooj muaj hlau nplaum yog huv ua ntej pib lub laum. Qhib lub rooj sib nqus sib nqus ua ntej thiab tom qab ntawd qhib lub cev muaj zog hloov.


4. Xaus kev drilling: Xaus lub cev muaj zog. Tom qab tus ntxaiv nres nres, tshem cov ntawv hlau tawm ntawm lub cev nrog cov hlau hlau, thiab tom qab ntawd txuas ntxiv ua haujlwm.
