Daim duab qhia txog qhov sib txawv pitch xov nrog qhov dav ntawm cov hniav tas li. Thawj lub suab ntawm cov xov no yog 5 hli, thiab lub suab nce 1 hli txhua zaus cov ntxaiv tig. Tool dav 3mm
Hom ntawv: G34 X(U) Z(W) FK (incremental value of the pitch for one revolution of spindle);
Cov qauv ntawm qee lub tshuab yog G34 X (U) Z (W) FR (tus nqi nce ntxiv ntawm lub suab rau ib qho kev sib hloov ntawm spindle);
