Mano osiyanasiyana ali ndi zotsatirazi pa tsamba la macheka podula nkhuni:

1. Kuthamanga kosiyana kosiyana

2. Kunyezimira kosiyana

3. Mbali ya mano a tsamba lokhalokha ndi yosiyana

4. Kuuma kwa thupi, flatness, kulumpha kumapeto ndi zofunikira zina za tsamba la macheka ndizosiyana

5. Palinso zina zofunika pa liwiro la makina ndi liwiro la kudyetsa nkhuni

6. Imakhalanso ndi zambiri zokhudzana ndi kulondola kwa zida za macheka

Mwachitsanzo, kudula kwa mano 40 sikupulumutsa ntchito ndipo phokoso lidzakhala lopanda phokoso chifukwa cha kukangana kochepa, koma kudula kwa 60-mano kumakhala kosavuta. Nthawi zambiri, ukalipentala amagwiritsa ntchito mano 40. Ngati phokoso liri lotsika, gwiritsani ntchito zokhuthala, koma zoonda kwambiri ndi zabwinoko. Mano akachuluka, m'pamenenso macheka amawoneka bwino, ndipo phokoso limakhala lopanda phokoso ngati makina anu ali okhazikika.

Kuchuluka kwa mano a sowo, kunena zambiri, kuchuluka kwa mano, kuchulukira m'mphepete pa nthawi imodzi, kumagwira ntchito bwino, koma mano odula kwambiri amafunika kugwiritsa ntchito carbide yolimba kwambiri, mtengo wa tsamba la macheka. ndi okwera, koma sawtooth ndi wandiweyani kwambiri, mphamvu ya chip pakati pa mano imakhala yaying'ono, zomwe zimakhala zosavuta kuchititsa kuti tsamba la macheka liwotche; Komanso, ngati pali ambiri macheka mano, ngati mlingo chakudya si zikugwirizana bwino, kudula kuchuluka kwa dzino lililonse adzakhala laling'ono kwambiri, amene adzawonjezera kukangana pakati kudula m'mphepete ndi workpiece, ndi zimakhudza moyo utumiki wa tsamba. . Nthawi zambiri malo otalikirana ndi mano ndi 15-25mm, ndipo mano oyenerera ayenera kusankhidwa molingana ndi zomwe acheke.
