Enspeksyon nan figi k ap travay nan nivo lespri
Pa gen okenn protrusion yo pèmèt sou sifas k ap travay nan nivo lespri a, ak plat li dwe satisfè kondisyon ki nan Tablo 6-10-54. Longè figi k ap travay la se 150-200 250-300, epi devyasyon plat la se<0.003 <0.005. For the grinding and grinding working face, the flatness is verified by the zero-level knife-edge ruler whose size is not less than the length of the inspected face, and the light gap method is used for verification , this verification work should be carried out at several positions in the longitudinal, transverse and diagonal directions of the working face. The largest gap seen is the flatness deviation of the surface. When estimating the size of the gap, it can be compared with the standard gap composed of gauge blocks.
Pou plat la nan sifas la k ap travay grate, sèvi ak plak la plat zewo-nivo pou teste pa metòd la koloran. Kantite tach nan yon zòn kare ki gen yon longè bò 25mm pa ta dwe mwens pase 25 pwen pou yon nivo ki gen yon valè divizyon 0.02 jiska 0.{{ 10}}5mm/m, epi yo pa ta dwe mwens pase 20 pou yon nivo ak yon valè divizyon 0.06 a 0.10mm/m Tach yo ta dwe distribye respire.
Dwat sifas k ap travay ki gen fòm V verifye pa metòd penti ak mandrin verifikasyon an. Mete mandrin an kouvwi ak poud plon wouj sou sifas ki gen fòm V pou vire, epi liy kontak yo wè sou sifas ki gen fòm V yo pa pèmèt yo gen yon diskontinuite ki gen plis pase 10mm.
