Kufotokozera Kwachidule:
Multi-blade saw blade ndi chida chodula chomwe chimagwiritsidwa ntchito pokonza matabwa, nthawi zambiri chimapangidwa ndi chitsulo chothamanga kwambiri kapena carbide. Ili ndi mbali zingapo zodziyimira pawokha zomwe zimatha kudula matabwa angapo nthawi imodzi, motero amatchedwa "macheka amitundu yambiri."
Mapangidwe a tsamba la macheka ambiri ndi apadera kwambiri. Mphepete mwake iliyonse imagwira ntchito palokha, kotero kuti matabwa angapo amatha kudulidwa nthawi imodzi. Kapangidwe kameneka kamapangitsa kuti matabwa azitha kugwira bwino ntchito chifukwa amachepetsa nthawi yosintha macheka komanso amachepetsa kuwononga nkhuni.
Mitundu yambiri ya macheka imakhala ndi ntchito zambiri ndipo ingagwiritsidwe ntchito podula mitundu yosiyanasiyana ya matabwa, kuphatikizapo matabwa a softwood, hardwood ndi composite. Kuphatikiza apo, itha kugwiritsidwanso ntchito kudula zida zina zomwe si zamatabwa monga pulasitiki, mphira ndi zitsulo.
Ubwino wamtundu wamitundu yambiri ndi wofunika kwambiri, chifukwa ngati mtundu wa macheka suli wabwino, ukhoza kuchititsa kuti pamwamba pa matabwa asakhale osagwirizana kapena osweka.
