mphero zomaliza

Ndi zida ziti zomwe zimagwiritsidwa ntchito pogaya zida?

Zida zomwe zimagwiritsidwa ntchito pogaya zida zimaphatikizapo chitsulo chothamanga kwambiri, zitsulo za ufa wothamanga kwambiri, aloyi yolimba, PCD, CBN, cermet ndi zida zina zolimba kwambiri. Zida zachitsulo zothamanga kwambiri zimakhala zakuthwa komanso zimakhala zolimba bwino, pomwe zida za carbide zimakhala zolimba koma zolimba. Kuchulukana kwa chida cha carbide NC mwachiwonekere ndikwambiri kuposa chida chachitsulo chothamanga kwambiri. Zida ziwirizi ndizomwe zimagwiritsidwa ntchito pobowola, ma reamers, oyika mphero ndi matepi. Ntchito ya ufa zitsulo mkulu liwiro zitsulo ndi pakati pa zipangizo ziwiri pamwamba, amene makamaka ntchito kupanga akhakula mphero wodula ndi wapampopi.

Zida zachitsulo zothamanga kwambiri sizimakhudzidwa ndi kugunda chifukwa cha kulimba kwawo bwino. Komabe, tsamba la carbide NC limakhala lolimba komanso lolimba, lozindikira kwambiri kugundana, ndipo m'mphepete mwake ndi losavuta kulumpha. Choncho, pogaya, kugwira ntchito ndi kuika zida za simenti za carbide ziyenera kusamala kwambiri kuti zisawonongeke pakati pa zida kapena kugwa kwa zida.

Chifukwa chakuti kulondola kwa zida zachitsulo zothamanga kwambiri ndizochepa, zofunikira zawo zogaya sizokwera, ndipo mitengo yake siili yokwera, opanga ambiri amakhazikitsa zida zawo zogwirira ntchito kuti azipera. Komabe, zida zomangika za carbide nthawi zambiri zimafunika kutumizidwa ku malo ogawira akatswiri kuti apeye. Malinga ndi ziwerengero za malo opangira zida zapakhomo, zoposa 80% ya zida zomwe zimatumizidwa kuti zikonze ndi zida za simenti za carbide.
