PDC OR PCD DILL BIT ? KUSIYANA NDI CHIYANI?
Kubowola kwa PDC kumatanthauza Polycrystalline Diamond Cutter core bit
Zitsime zakale kwambiri zinali zitsime zamadzi, maenje osaya omwe amakumbidwa ndi manja m'madera omwe madzi amayandikira pamwamba, nthawi zambiri amakhala ndi mipanda kapena makoma amatabwa.
PDC amapangidwa ndi kuphatikiza zigawo zina za diamondi polycrystalline (PCD) ndi wosanjikiza simenti carbide liner pa kutentha ndi kuthamanga kwambiri.
Ma PDC ndi ena mwa zida zolimba kwambiri pazida zonse za diamondi.
PCD imangotanthauza Daimondi ya Polycrystalline:
PCD nthawi zambiri amapangidwa ndi sintering ambiri yaying'ono diamondi makhiristo single pa kutentha kwambiri ndi kuthamanga kwambiri.
PCD ili ndi kulimba kwabwino kwa fracture ndi kukhazikika kwabwino kwa kutentha, ndipo imagwiritsidwa ntchito popanga mabowola a geological.
PDC ili ndi zabwino zake zokana kuvala kwa diamondi ndi kulimba kwabwino kwa carbide.
