Kugwiritsa Ntchito Mankhwala

Roller Reamer yapangidwa kuti igwiritsidwe ntchito mosiyanasiyana koma makamaka kuti ikhale yokhazikika pobowola m'njira zovutira kwambiri. Idzakwanira kukula kwa mabowo kuyambira mainchesi 4 5/8 mpaka 26. Kuphatikiza apo, thupi lililonse mwa kusintha kosavuta kwa mabuloko ndi kusankha bwino zida zodulira, lidzagwirizana ndi makulidwe osiyanasiyana a mabowo.

Mtundu wa chinthu

Mitundu itatu yosiyanasiyana ya zodulira (T,F ndi B) ikupezeka:

Mtundu T: Wopukutidwa, wopangidwa ndi mano olimba akuthwa kuti apange mawonekedwe ofewa.
Mtundu F: Wopukutidwa, wopangidwa ndi makina okhala ndi mano olimba athyathyathya, kuti apange mawonekedwe olimba apakatikati.
Mtundu B: Yokhala ndi mabatani a tungsten carbide osindikizidwa, kuti ikhale yolimba.
