gudumu lopera la corundum

Magudumu a Brown corundum ndiye chida chofunikira kwambiri pogaya. Gudumu logaya ndi thupi lokhala ndi porous lomwe limapangidwa powonjezera binder mu abrasive, kukanikiza, kuyanika ndi kukuwotcha. Chifukwa cha ma abrasives osiyanasiyana, zomangira ndi njira zopangira, mawonekedwe a mawilo akupera ndi osiyana kwambiri, omwe amakhudza kwambiri kugaya khalidwe, zokolola ndi chuma. Makhalidwe a mawilo akupera makamaka anatsimikiza ndi abrasive, tinthu kukula, binder, kuuma, kapangidwe, mawonekedwe ndi kukula. Malinga ndi abrasives ntchito, akhoza kugawidwa mu abrasives wamba (corundum ndi silicon carbide, etc.) mawilo akupera. Malinga ndi mawonekedwe, akhoza kugawidwa mu lathyathyathya gudumu akupera, gudumu akupera bevel, cylindrical akupera gudumu, chikho akupera gudumu, mbale akupera gudumu, etc. Malinga ndi binder, akhoza kugawidwa mu ceramic akupera gudumu, utomoni akupera gudumu, mphira akupera gudumu ndi zitsulo akupera gudumu. The magawo khalidwe la akupera gudumu makamaka monga abrasive, tinthu kukula, kuuma, binder, gulu nambala, mawonekedwe, kukula, liniya liwiro ndi zina zotero. Chifukwa gudumu logaya nthawi zambiri limagwira ntchito mothamanga kwambiri, musanagwiritse ntchito, liyenera kuyesedwa kuti lizizungulira (kuonetsetsa kuti gudumu lopukuta silidzasweka pa liwiro lapamwamba kwambiri) ndi static balance (kuteteza chida cha makina kuti chisagwedezeke pogwira ntchito). Pambuyo pogwira ntchito kwa nthawi, gudumu lopera liyenera kukonzedwa kuti libwezeretse ntchito yopera ndikuwongolera ma geometry.
