Kupopera mchenga wonyowa kumachitika kudzera mu pampu yopopera ndi mpweya wopanikizika kudzera mu mfuti yopopera kuti mupopere madzi opopera mofulumira kwambiri pamwamba pa workpiece kuti
kukonzedwa, ndipo mchenga umapopedwa kuchokera mu valavu ya mchenga.
3. Pangani kusiyana pa malo ogwirira ntchito:
Kupukuta mchenga wouma pogwiritsa ntchito kungayambitse kuipitsa fumbi
Ntchito yonyowa mchenga siipanga fumbi, siitulutsa madzi otayira poizoni, siipanga kuipitsa chilengedwe, kukhazikitsa zida n'kosavuta komanso kosavuta, sikufuna malo ena ogwirira ntchito.
