Mitundu Yosiyanasiyana Yamagudumu Opera
1. Malinga ndi abrasive ntchito, akhoza kugawidwa mu abrasive wamba (corundum, pakachitsulo carbide, etc.) mawilo akupera, zachilengedwe abrasive super abrasive (diamondi, kiyubiki boron nitride, etc.) akupera mawilo;
2. Malinga ndi mawonekedwewo, amatha kugawidwa kukhala gudumu lopukutira lathyathyathya, gudumu lopukutira la bevel, gudumu lopukutira la cylindrical, gudumu lopukutira chikho, gudumu lopukutira, etc;
3. Ikhoza kugawidwa m'magudumu a ceramic, gudumu lopukuta utomoni, gudumu lopukuta labala,zitsulo popera gudumu, etc. malinga ndi chomangira. The magawo khalidwe la gudumu akupera makamaka monga abrasive, mamasukidwe akayendedwe, kuuma, chomangira, mawonekedwe, kukula, etc.
Popeza kuti gudumu logaya nthawi zambiri limagwira ntchito pa liwiro lalikulu, kuyesa kozungulira (kuonetsetsa kuti gudumu lopera silingaduke pa liwiro lapamwamba kwambiri) komanso kuyesa kwa static (kuteteza kugwedezeka kwa gudumu).chida cha makina pa nthawi ya ntchito) ziyenera kuchitidwa musanagwiritse ntchito. Pambuyo pa gudumu lopera likugwira ntchito kwa nthawi, liyenera kukonzedwa kuti libwezeretse ntchito yopera ndi geometry yolondola.
Gwiritsani ntchito chitetezo cha gudumu lopera
Gonjetsani Njira Yoyikira
Pakuyika, chitetezo ndi khalidwe la gudumu lopera liyenera kufufuzidwa poyamba. Njirayo ndikugogoda m'mbali mwa gudumu lopera ndi nyundo ya nayiloni (kapena cholembera). Ngati phokoso likumveka bwino, zili bwino.
(1) Vuto la malo
Pomwe chopukusira chayikidwa ndi funso loyamba lomwe tiyenera kuliganizira muunsembe ndondomeko. Pokhapokha ngati tasankha malo oyenera, tingagwire ntchito ina. Ndizoletsedwa kukhazikitsa makina opukutira akuyang'anizana ndi zida zapafupi ndi ogwira ntchito kapena kumene anthu amadutsa nthawi zambiri. Kawirikawiri, chipinda chachikulu chiyenera kukhala ndi chipinda chokhala ndi magudumu opera. Ngati kuli kotheka kukhazikitsa chipinda cha makina opera odzipereka chifukwa cha kuchepa kwa malo omera, chotchingira chotchinga chokhala ndi kutalika kosachepera 1.8m chidzayikidwa kutsogolo kwa makina opera, ndipo chotchingacho chiyenera kuyikidwa. olimba ndi ogwira mtima.
(2) Vuto losalongosoka
Kusalinganika kwa gudumu lopera kumayamba makamaka chifukwa chosalondolakupangandi kukhazikitsa gudumu lopera, lomwe limapangitsa kuti pakati pa mphamvu yokoka ya gudumu lopera lisagwirizane ndi gwero lozungulira. Kuwonongeka koyambitsidwa ndi kusalinganika kumawonetsedwa makamaka m'mbali ziwiri. Kumbali imodzi, pamene gudumu lopera limayenda mothamanga kwambiri, limayambitsa kugwedezeka, zomwe zimakhala zosavuta kuchititsa zizindikiro za kugwedezeka kwa polygonal pamtunda wa workpiece; Kumbali ina, kusalinganika kumathandizira kugwedezeka kwa spindle ndi kuvala kwa bere, zomwe zingayambitse kuthyoka kwa gudumu lopera, kapena kuyambitsa ngozi. Chifukwa chake, pamafunika kuti static balance ichitike kaye chuck itayikidwa paofesi yamchenga yowongoka kuposa kapena yofanana ndi 200mm. Kukhazikika kwa static kudzabwerezedwa pamene gudumu logaya likukonzedwanso kapena kupezedwa mopanda malire panthawi ya ntchito.
