Isizathu
1. I-blade enqamlezileyo ayibukhali kwaye i-blade edibeneyo emibini ayilingani-phezulu.
2. Indawo ye-drill kunye ne-shank concentricity ayifezeki kwiikhrayitheriya.
3. Umtshini ukwimeko yokuphela kwe-spindle engalunganga.
4. Inkqubo yebhodi (i-artifact) isendleleni.
5. Ukujikeleza kwe-Spindle kunye nesantya sokusika asihambelani.
6. I-adapter concentricity iphantsi kwaye enye idatha yobugcisa ayikho kumgangatho.
Isizathu
1. Indawo ephakathi kunye ne-shank i-misalignment, okanye indawo ephakathi ayibukhali.
2. I-artifact isendleleni ngexesha lokomba.
3. Ukujikeleza kwe-Spindle kunye nesantya sokutya isixhobo asihambelani.
4. I-adapter concentricity iphantsi kwaye enye idatha yobugcisa ayikho kumgangatho.
5. I-spindle yomatshini wokudinwa ikhululekile okanye yonakele.
Isizathu:
1. Umphetho we-blade awubukhali, i-drill bit kufuneka itshintshwe.
2. I-Spiral groove (i-chip groove) kukuxinana okuya kukhokelela ekususweni kwetshiphu kakubi.
3. I-Artifact (izinto eziphathekayo) ngumswakama ngaphezu komda okanye umgangatho weglue awulungile (ngakumbi ibhodi yefiber kunye neplywood).
4. Isantya sokutya isixhobo asihambelani nezinto kunye nobunzulu.
5. Khetha uhlobo olufanelekileyo lwe-drill bit yezinto zokucubungula.
