Pontšo ea Sehlahisoa
Lisebelisoa tsa ho cheka lifofane li matla ho feta likotoana tsa boro tse nang le likotopo bolelele bohle ba tsona. Bakeng sa ho cheka masoba ka thepa e matla, e matla e phahameng e kang tšepe e sa hloekang, titanium le Inconel. E loketse bakeng sa ho cheka aluminium le li-alloys tsa tšepe tse mahareng ho isa tlase. Black oxide e tšoaroang HSS e matlafatsa ho hanyetsa mocheso le ho lelefatsa bophelo ba lisebelisoa, ka phekolo e tšesaane ea oxide e holim'a metsi ho feta black oxide e atisang ho sebelisoa ho khetholla lisebelisoa tsa tšepe ea cobalt; tshebetso e tšoana le lisebelisoa tse sa koaeloang. Shank e halefileng ea selemo e thibela ho kobeha ho sa feleng ha likoti tse phuntsoeng li sa tsamaisane ka kotloloho. Li-shank tse pota-potileng li ka sebelisoa ka mefuta e fapaneng ea lisebelisoa tsa lisebelisoa.
Ho cheka ho nang le ntlha e arohaneng ea likhato tse 118 kapa 135 ho bolela hore ho hlokahala matla a tlaase ho phunya ka har'a mosebetsi, ho thibela ho cheka ho thella holim'a thepa, ho itšepa le ho fokotsa matla a hlokahalang bakeng sa ho cheka. Ntle le ho cheka litšepe, aluminium le tšepe e sa hloekang, boro ena e ka boela ea sebelisoa ho cheka lehong, tšepe le lisebelisoa tse ling, kaha e entsoe ka tšepe ea boleng bo holimo ea lebelo le holimo. Ho feta moo, e ka boela ea sebelisoa ho cheka lisebelisoa tse ling tse ngata ka letsoho, e leng se etsang hore e be e 'ngoe ea lisebelisoa tse ngata tse fumanehang.
