Zofunikira zazikulu zamachubu owoneka bwino:
Chitoliro ndi khoma mwatsatanetsatane, kutsirizitsa apamwamba, sanali kutentha mankhwala zitsulo okusayidi wosanjikiza, khoma lamkati la ukhondo mkulu zitsulo kupirira kuthamanga, mapindikidwe ozizira, flaring, flattening palibe ming'alu, akhoza kupanga zosiyanasiyana mapindikidwe zovuta ndi processing makina. . Mtundu wa chitoliro: choyera chowala, chokhala ndi zitsulo zonyezimira kwambiri.

Zolinga zazikulu zamachubu owoneka bwino:
Galimoto, makina ndi Chalk zina ntchito mwatsatanetsatane zitsulo chitoliro, malizitsani zofunika makina mkulu. Ndipo tsopano kwa ogwiritsa ntchito mwatsatanetsatane zitsulo, malizitsani ogwiritsa ntchito kwambiri, ndipo chifukwa cha kulekerera kwabwino kwa chitoliro chapamwamba kwambiri kumatha kusungidwa pawaya wa 2-8, ogwiritsa ntchito machining ambiri kuti apulumutse ntchito, zida, kutaya nthawi, chitsulo chosasunthika. chitoliro kapena bala pang'onopang'ono kusandulika mwatsatanetsatane kuwala chitoliro.
