Masiku ano,chitsamba nyundo chidas kukhala wotchuka kwambiri. Zida zimenezi sizingangochitika zokha kapenanyundo yamtchirepamwamba pa miyala ndi konkire, kuti apeze mapeto okongoletsera kapena osakhala otsika, komanso amatha kuchotsa zokutira (monga mzere wa magalimoto). Monga zida zama diamondi akatswiri
ogulitsa ku China, Sunny Superhard Tools adayamba R&Dnyundo yamtchirezida msanga kwambiri. Titha kukupatsirani mitundu yonse ya nyundo zamtchire zamtengo wapatali, kuti zigwirizane ndi mitundu yosiyanasiyana ya makina opera ndi zokutira pansi.

Zopukusira pansi za Lavina zimagwiritsidwa ntchito kwambiri padziko lonse lapansi, ndipo zachidziwikire, tidapanga mutu wofananira wa nyundo kuti ugwirizane nawo. Mutu wa nyundo wa chitsamba ichi wa lavina uli ndi mano 30 YG8 carbide pa chogudubuza chachitsulo chopanda kanthu. Mkati mwa wodzigudubuza amapangidwa ndi kubala, manja, makina ochapira masika, ndi zina zotero, ndi kudzazidwa ndi mafuta. Mutha kuzungulira chogudubuza mosavuta ndi zala zanu. Kukonzekera koyenera kumatsimikizira kugwira ntchito kwapamwamba komanso moyo wautali.

• Zapangidwa mwapadera kuti zigwiritsidwe ntchito pa zopukusira pansi za Lavina
• Gwiritsani ntchito mano a carbide a 4.7mm apamwamba kwambiri a YG8
• Kapangidwe koyenera kwachitsamba nyundo wodzigudubuza
• Kuwunikiridwa bwino musanatumize
• 3 zidutswa pa bokosi ndi odzaza bwino
