Ukukhethwa kwempahla ye-chisel

Uma kuziwa ekukhetheni i-material yeshizolo, kubalulekile ukucabangela izici ezithile nezici zezinto ezitholakalayo. Esimeni se-40Cr, 42CrMo, 46A, kanye ne-48A, into ngayinye inezimfanelo zayo ezihlukile eziyenza ifanelekele izinhlelo zokusebenza ezahlukene. Nansi inkomba yokuthi ungayikhetha kanjani into efanele yeshizolo lakho:

I-40Cr: Lolu hlobo lwensimbi lwaziwa ngamandla alo aphezulu kanye nokuqina. Ngokuvamile isetshenziswa ekwenzeni amashizolo adinga ukuqina nokumelana nokuguga. Uma udinga i-chisel yezinhlelo zokusebenza ezisindayo ezifana nokusebenza kwensimbi noma ukwakha, i-40Cr ingaba yinketho efanelekile ngenxa yezakhiwo zayo ezinhle kakhulu zemishini.

I-42CrMo: Le nsimbi ye-alloy ibonakala ngamandla ayo aphezulu, ukuqina okuhle, nokumelana okuhle kakhulu nokugqoka nokuhuzuka. Amashizolo enziwe nge-42CrMo alungele izinhlelo zokusebenza ezidinga ukumelana nomthelela ophezulu kanye nekhono lokumelana nemithwalo esindayo. Lokhu okubalulekile kuvame ukukhethwa kumashizolo asetshenziswa ekwakheni, ezimayini, nakwezinye izimboni ezidinga kakhulu.

I-46A: I-46A insimbi iyinsimbi yesakhiwo sekhabhoni eyaziwa ngokushisela kwayo okuhle nokuqina kwayo. Amashizolo enziwe kusuka ku-46A afanele ukusetshenziswa kwenjongo evamile lapho kudingeka khona ibhalansi yamandla nokusebenza. Uma udinga ishizolo eliguquguqukayo elingalolongwa kalula futhi lilungiswe, i-46A ingaba inketho enhle.

I-48A: Lolu hlobo lwensimbi lwaziwa ngokuqukethwe kwayo okuphezulu kwekhabhoni, okuhlinzeka ngobulukhuni obuhle kakhulu nokumelana nokugqoka. Amashizolo enziwe kusuka ku-48A afaneleka kahle izinhlelo zokusebenza ezidinga imiphetho ebukhali kanye nokusebenza okuhlala isikhathi eside. Uma udinga itshizi ukuze usebenze ngokunemba njengokuqopha ngokhuni noma ukuqoshwa kwensimbi, i-48A ingaba yinketho efanelekile.
