Kupanga machubu osasunthika otentha ndi gawo lofunikira kwambiri pakupindika, cholinga chake ndikuvala chubu cholimba chokulungidwa mu chubu chopanda kanthu. Malinga ndi kapangidwe ndi mapindikidwe makhalidwe kuboola ndondomeko kuboola makina akhoza kugawidwa mu njira ochiritsira perforating: kuboola oblique, kuboola kukankha ndi kuthamanga perforation, kuboola ndi oblique ambiri ankagwiritsa ntchito, mawonekedwe a rotary kuboola makina masikono ndi mpukutu, mabakiteriya chilinganizo. cone) ndi chimbale mitundu itatu kuboola mphero anagubuduza masikono mphero ntchito ang'onoang'ono, pamene mayunitsi lalikulu ntchito mabakiteriya mtundu kuboola masikono. Punch ya disc sigwiritsidwa ntchito kawirikawiri. Kaya mpukutu mawonekedwe bwanji, pofuna kuonetsetsa kuti chubu kuluma ndi kukwaniritsa kuboola ndondomeko ali perforated chulucho (mpukutu cholowera chulucho), akupera mphero chulucho (mpukutu chotuluka chulucho) ndi adagulung'undisa Mzere (mochuluka gawo la cholowa chulucho ndi kotulukira chulucho pakati) kupanga.

Mpukutu woboola amagwiritsa ntchito zodzigudubuza ndi kapangidwe ka manja odzigudubuza, zonse zosokoneza kapena kuphatikiza kusokoneza kuphatikiza makiyi. Choncho, pamene mpukutu zidutswa, odzigudubuza akhoza kupitiriza ntchito, kuchepetsa tooling ndalama. Zing'onozing'ono zodzigudubuza zowonjezera kusankha kwa 45 kapena 40Cr, kuzimitsidwa ndi kupsya mtima. Zodzigudubuza zazikulu za 42CrMo, kuzimitsa ndi kutenthetsa. Opanga zinthu zopukutira pakali pano akugwiritsa ntchito zovuta kwambiri, opanga ena amagwiritsa ntchito 45, 55 ndi zina zotero kupanga zitsulo zapamwamba kwambiri za carbon structural. Opanga ena amagwiritsa ntchito 50Mn, 65Mn, 70Mn, 70Mn2Mo, 60CrMnMo alloy cast kapena forged; Zofunikira zamtundu wa kuuma sizigwirizana, ndipo zina zimafuna HB180-220, zina zimafuna HB220-260. Kuti muwonjezere kuluma kwa chodzigudubuza chachikulu chodzigudubuza chakuya cha 0,8 ~ 1.2mm mauna chitsanzo cha chulucho cholowera.

Comprehensive zoweta ndi akunja opanga zinthu kusankha ndi ntchito, ine ndikuganiza: kusankha kuponyera mpukutu nkhonya 50Mn, 60CrMnMo mpweya zitsulo ndi zipangizo zina zoyenera, wina ali ndi mphamvu zabwino ndi kuvala kukana, chachiwiri umagwiritsidwa ntchito kwa aliyense anagubuduza mitundu ya zinthu chitoliro. . Kuuma Kuwongolera mu HB200-240 ndikoyenera.
