Abrasivekuomarara (hardness) zvinoreva kuomarara kwezvikamu zvinokwenya zviri pamusoro peabrasive kuti zvidonhe pasi pekuita kwemasimba ekunze, kureva kusimba kweabrasive binding agent kuti ibate maabrasive particles.Kana zvidimbu zvinoputika zvinodonha nyore , kuoma kweabrasive kuchava kwakaderera, uye zvinopesana, kuoma kuchava kwakakwirira.
Sarudzo yeabrasivekuomarara kunonyanya kutarisisa kugona kwekugaya uye kunaka kwenzvimbo yakagadziriswa.Iyo abrasive yakanyatsosarudzwa, iyo yakashata mabrasive particles haisi nyore kudonha, gumbo rekukuya riri nyore kuvhara, kupisa kwekukuya kunowedzera, uye workpiece iri nyore kupisa, iyo inokanganisa hutano hwepamusoro hwebasa rekushanda.Iko kushanda kwekugaya kwakaderera.Kana iyo abrasive yakasarudzwa yakanyanya kupfava, iyo abrasive particles inodonha kana ichiri kupinza, iyo inowedzera kurasikirwa kweiyo abrasive chishandiso, uye panguva imwecheteyo zviri nyore kurasikirwa neiyo chaiyo abrasive geometry, iyo inokanganisa machining accuracy. iyo workpiece, saka sarudzo yeabrasive hardness inofanira kuva pakati nepakati.Ukama huri pakati pekuoma kweabrasive uye kuoma kwepamusoro kunoratidzwa muMufananidzo 9.
Figure Hukama huri pakati pekuoma kweabrasive nekuoma kwepasi
(1) Pakuumba, kukuya nekukuya nzvimbo dzinopindirana, kuoma kweabrasive kunofanira kunge kwakakwirira.
(2) Kuoma kwechishandiso chinoputika kunofanira kunge kwakapfava kana ndege ichikuya, uye kuoma kwechishandiso chinoputika kunofanira kunge kwakapfava kana kupera kwechiso kukuya kuri nani pane kukuya kwedenderedzwa.
(3) Kuoma kwezvishandiso zvinoputika zvakasarudzwa zvekukuya denderedzwa remukati zvakakwirira kudarika denderedzwa rekunze uye kukuya ndege.
(4) Paunenge uchirodza maturusi, sarudza maturusi akapfava anokwesha.
(5) Kuomarara kwemaabrasives ekukuya anomhanya-mhanya ari 1-2 mamakisi akadzikira pane aya akajairika ekukuya abrasives.
Abrasive hardness yekusarudza nheyo:
(1) Pakukuya zvinhu zvakaoma, sarudza mabrasives akapfava, uye pakukuya zvinhu zvakapfava, sarudza mabrasives akaomarara.
(2) Pakukuya zvinhu zvesimbi zvinyoro uye zvakasimba zvisina ferrous, kuoma kunofanira kunge kwakapfava.
(3) Pakukuya zvinhu zvine urombo hwekupisa conductivity (alloy simbi, simende carbide, nezvimwewo), mabrasives akapfava anofanira kusarudzwa.
Sarudzo yeabrasivekuoma pasi penzira dzakasiyana dzekukuya
Kuoma kweabrasivemidziyo inoshandiswa pakucheka nekukuya denderedzwa rekunze rakapfava pane rekunze denderedzwa rinoshandiswa pakukuya chikafu chelongitudinal.Iyo nzira yekucheka inogaya maworkpieces ane yakakwirira geometric chimiro zvinodiwa semakona madiki, arcs kana makona ekurudyi, uye mabhasi, uye kuomarara kwezvishandiso zveabrasive ndeye 1-2 mamakisi kumusoro.
