Dowel Pin ke Eng?
Ka lehlakoreng le leng, aphini ea dowelke molamu o tiileng, o fatše hantle, oo hangata o entsoeng ka tšepe e sa hloekang kapa motsoako o thata. Bophara ba eona ba kantle bo boreleli, bo nepahetseng bo netefatsa boemo bo phetoang:
-
Mamello e thata:Ho otloloha ho tloaelehileng ka har'a 0.01 mm le mamello ea bophara ba ± 0.005 mm.
-
