Bothata ba bokaholimo ba mesebetsi e tloaelehileng e chitja bo ka lekanngoa ka ho toba ke mohlahlobi oa thatafalo oa Rockwell (sheba setšoantšo se ka tlase).
Leha ho le jwalo, bakeng sa mesebetsi e menyenyane e chitja (jwalo ka ha ho bontshitswe setshwantshong se ka tlase), teko e tobileng e sitiswa ke boholo ba yona bo bonyenyane le sebaka se thata. Re ka rarolla bothata bona jwang?
Ho rarolla mathata a ho leka mesebetsi e menyenyane e chitja, re fana ka ditharollo tse pedi tse pakiloeng tsa ho beha maemo:
Mokhoa oa ho Beha Lisebelisoa Sebakeng: Sebelisa linate tse tsamaellanang le litekanyo tsa mosebetsi e le lisebelisoa tsa ho beha. Beha li-workpiece tse chitja ka mokhoa o tsitsitseng ka har'a li-bore tsa linate, u netefatse hore li tiile ntle le ho sisinyeha kapa ho sekamela pele u etsa teko.
Mokhoa oa ho Hloma le ho Lokisa:Haeba ho se na lisebelisoa tse loketseng tse fumanehang, sebelisa mochine oa ho kenya oa metallographic joalo ka ka tlase ho kenya le ho lokisa karolo ea mosebetsi, e le ho fana ka tšehetso e tsitsitseng bakeng sa teko ea ho thatafala.
Kamora ho tiisa likarolo tsa mosebetsi, re etsa teko ea boima ka sesebelisoa sa ho leka boima ba Vickers sa 10kg. Mekhoa ea liteko ke e latelang:
1. Beha nate e nang le bolo ea aluminium butle-butle le bohareng tafoleng ea mosebetsi ea teko.
2. Bulela mohloli oa leseli oa sesebelisoa sa ho leka ho thatafala 'me u fetole khanya ho ea boemong bo nepahetseng, u qobe ho pepesehela ho feteletseng le meriti.
3. Potoloha lebili la letsoho le shebaneng butle ho fihlela setšoantšo sa bokaholimo ba bolo ea aluminium se hlakile ka mahlakore a bohale.
3. Suthisa tafole ea mosebetsi ea XY ea letsoho ho hokahanya bohareng ba lebala la pono le ntlha ea bolo ea aluminium, ho netefatsa hore ntlha ea teko e sebakeng se phahameng ka ho fetisisa sa bokaholimo bo chitja.
4. Beha diparamitha tsa teko ho sebopeho sa teko ya ho thatafala, mona re kgetha sekala sa HV2.
5.Tobetsa konopo ea Qala. Setei sa ho thatafala ha Vickers se tla theola indenter ka bohona, ebe se kenya -dwell-unloading ho fihlela indent e feletseng.
6.Kamora ho kenya letsoho, tobetsa Tekanyo e Iketsang. Sistimi ea ho lekanya ea teko ea thata ea Vickers e khetholla ho kenya letsoho ka bohona 'me e bala boleng ba thata, 'me sephetho sa thata ea HV se bontšoa skrineng.
Bakeng sa teko ea ho thatafala ha Rockwell e kaholimo, mochine oa ho thaepa oa metallographic le teko ea ho thatafala ha vickers, rea u amohela ho sheba webosaete ea rona. Re se re loketse ho araba lipotso tsa hau.
