Malamba a mchenga wa alumina wophatikizika ndi nsalu zofewa
Ma abrasives a bulauni a aluminiyamu, nsalu yoyera ya thonje, mchenga wokulirapo wapakatikati, nsalu yong'ambika m'manja, mchenga ndi dzanja, yoyenera kumanja kwa mchenga waung'ono, wosayenerera lamba wa mchenga.
Amagwiritsidwa ntchito makamaka mu: matabwa a pine, matabwa a chipika, mipando, zopangidwa ndi manja, zopangidwa ndi rattan.
Grit: 60 # -600 #
Ma abrasives a bulauni ophatikizika a aluminiyamu, nsalu zophatikizika, mchenga wobzala wapakatikati, nsalu ya emery ndi yofewa komanso yolimba, yoyenera malamba opapatiza amchenga.
Amagwiritsidwa ntchito makamaka mu: matabwa a pine, matabwa a chipika, mipando, zinthu zopangidwa ndi manja, zinthu za rattan, komanso zoyenera pogaya zitsulo zonse.
Grit: 60 # -600 #
Pambuyo pa chithandizo, ma abrasives a bulauni osakanikirana, nsalu zosakanikirana, mchenga wobzalidwa kwambiri, nsalu ya emery ndi yofewa komanso yolimba, yoyenera malamba opapatiza.
Amagwiritsidwa ntchito makamaka mu: chitsulo chosapanga dzimbiri, chitsulo, super hard titanium alloy.

Mankhwala akuluakulu ndi AL2O3, omwe amapangidwa ndi kusungunula bauxite, zitsulo zachitsulo ndi anthracite mu ng'anjo yamagetsi yamagetsi pa kutentha kwambiri kuposa 2250 ℃.Mtundu wa Brown wosakanizidwa alumina abrasive ndi bulauni.Izi abrasive ali ndi kuuma kwina ndi kulimba, wamphamvu akupera mphamvu, ndipo akhoza kupirira kukakamizidwa kwambiri.Ili ndi mawonekedwe a kukana kutentha kwambiri, kukana kwa okosijeni, kukana kwa dzimbiri komanso kukhazikika kwamankhwala abwino.Chifukwa cha mphamvu zake zolimba kwambiri, ndizoyenera pogaya zida zolimba kwambiri, zoyenera chitsulo wamba, chitsulo cha carbon, alloy steel, ndipo chitha kugwiritsidwa ntchito pokonza matabwa olimba.Itha kugwiritsidwanso ntchito ngati choloweza m'malo ngati ma abrasives ena sakukwanira.Amatchedwa abrasive ndipo amagwiritsidwa ntchito kwambiri.
Kukula kwa njere ya abrasive lamba wa abrasive kumakhala ndi chikoka chachikulu pakukula kwa kugaya ndi kuuma kwapamwamba kwa kukonza.Pofuna kuonetsetsa kuti roughness ndi processing Mwachangu wa workpiece, ayenera kutengera zofunika zosiyanasiyana za processing, ntchito ya makina chida, ndi mikhalidwe yeniyeni ya processing, monga chiphaso processing wa workpiece, The mawonekedwe apamwamba, zakuthupi, chithandizo cha kutentha, kulondola, roughness ndizosiyana kusankha malamba a grit osiyanasiyana.Nthawi zambiri, grit wa coarse amagwiritsidwa ntchito pogaya ndipo grit imagwiritsidwa ntchito popera bwino.(Zotsatirazi ndizomwe zimangogwiritsidwa ntchito, ndipo zochitika zenizeni zogwirira ntchito zimagwirizana ndi machitidwe a makina opangira makina ndi zina.)
