Kudziwa zofunikira za gudumu lopera kudzakuthandizani kupeza yoyenera

gudumu loperandi mtundu wa ntchito kudula, ndi mtundu wa abrasive kudula zida.Mu gudumu lopera, abrasive ali ndi ntchito yofanana ndi ma serrations mu tsamba la macheka.Koma mosiyana ndi mpeni wa macheka, womwe umakhala ndi zopindika m'mphepete mwa gudumu, gudumu lopukutira limagawidwa pawiri.Zikwizikwi za abrasive particles amasunthidwa kudutsa chogwirira ntchito kuchotsa tiziduswa tating'onoting'ono.

 

Nthawi zambiri ogulitsa abrasive amapereka mitundu yosiyanasiyana yazinthu zosiyanasiyana zogaya pokonza zitsulo.Kusankha mankhwala olakwika kungawononge nthawi ndi ndalama zambiri.Pepalali limapereka mfundo zina zofunika pakusankha gudumu lopera bwino kwambiri.

 

Zowononga: mtundu wa mchenga

 

Gudumu lopera kapena mwala wina wopera uli ndi zigawo ziwiri zazikulu:

 

Ma grits omwe amaduladi, ndi kuphatikiza komwe kumagwira grits pamodzi ndikuthandizira grits pamene kudula.Mapangidwe a gudumu lopera amatsimikiziridwa ndi chiŵerengero cha abrasive, binder ndi kusowa pakati pawo.

Ma abrasives enieni omwe amagwiritsidwa ntchito mu gudumu lopera amasankhidwa malinga ndi momwe amachitira ndi zinthu zogwirira ntchito.Abrasive yabwino ndi yomwe imatha kukhalabe yakuthwa komanso yosasunthika mosavuta.Pamene passivation ikuyamba, abrasive idzasweka kuti apange mfundo zatsopano.Mtundu uliwonse wa abrasive ndi wapadera, ndi kuuma kosiyana, mphamvu, kulimba kwa fracture ndi kukana mphamvu.

Alumina ndiye abrasive omwe amagwiritsidwa ntchito kwambiri pogaya mawilo.

 

Nthawi zambiri amagwiritsidwa ntchito pogaya zitsulo za carbon, alloy steel, high speed chitsulo, malleable cast iron, chitsulo, bronze ndi zitsulo zofanana.Pali mitundu yambiri yosiyanasiyana ya aluminiyamu abrasives, iliyonse imapangidwa mwapadera ndikusakanikirana kwa mtundu wina wa ntchito yopera.Mtundu uliwonse wa aluminiyamu uli ndi dzina lake: nthawi zambiri kuphatikiza zilembo ndi manambala.Mayinawa amasiyana kuchokera kwa wopanga ndi wopanga.

 

Zirconia aluminiyamundi mndandanda wina wa abrasives, opangidwa ndi kusakaniza alumina ndi zirconia mosiyanasiyana.Kuphatikiza uku kumapanga abrasive yolimba, yolimba yomwe imagwira bwino ntchito pogaya movutikira, monga podulira.Komanso ntchito mitundu yonse ya zitsulo ndi aloyi zitsulo.

Monga aluminiyamu, mitundu ingapo ya zirconia alumina ilipo.

 

Silicon carbide ndi abrasive ina yomwe imagwiritsidwa ntchito pogaya chitsulo chotuwira, chitsulo chozizira, mkuwa, mkuwa wofewa ndi aluminiyamu, komanso miyala, mphira ndi zitsulo zina zopanda chitsulo.

 

Ceramic aluminiyamundiye chitukuko chaposachedwa kwambiri munjira ya abrasive.Ndi njere yoyera kwambiri yopangidwa ndi gel sintering process.Izi zitha kuphwanya sikelo ya micron pa liwiro lolamulidwa.Kenako, zikwi za mfundo zatsopano zikupanga.Ceramic alumina abrasives ndi olimba kwambiri ndipo amagwiritsidwa ntchito povuta kwambiri pogaya chitsulo.Nthawi zambiri amasakanizidwa ndi ma abrasives ena mosiyanasiyana kuti akwaniritse bwino ntchito yawo pazinthu zosiyanasiyana ndikugwiritsa ntchito.
