Nzira yekudzivirira sei kupisa pakucheka workpieces?

Iyo yekucheka disc inogadzirwa neresin sebinder, inowedzerwa negirazi fiber mesh, uye yakasanganiswa nezvinhu zvakasiyana.Kucheka kwayo kunonyanya kukosha kune zvakaoma kucheka zvinhu zvakadai sesimbi yealloy uye simbi isina tsvina.Nzira dzekucheka dzakaoma uye dzakanyorova dzinoita kuti kuchekwa kuwedzere kugadzikana.Panguva imwecheteyo, kusarudzwa kwezvinhu zvekucheka uye kuoma kunovandudza kucheka kushanda uye kunoderedza mari yekugadzira.Asi panguva yekucheka, panogona kunge painewo tsaona dzemaworkpieces anopiswa.

Tingadzivisa sei kupisa panguva yekucheka, izvo zvinogona kukanganisa kushanda kwekucheka kwakaderera?

1, Kusarudzwa kwekuoma

Kana iyo kuoma kwakanyanyisa, iyo metallographic chimiro chechinhu chichapiswa, uye microstructure yezvinhu haigoni kuongororwa zvakarurama, zvichiita zvikanganiso;Kana iyo yakaoma yakanyanya kuderera, ichaita kuti pave nekucheka kwakaderera uye kutambisa blade yekucheka.Kuti udzivise kupisa uye kupinza panguva yekucheka, chete kuoma kwezvinhu kunoda kuongororwa uye kushandiswa kwakakodzera kweinotonhorera.

2, Kusarudzwa kwezvinhu zvakasvibiswa

Iyo yakasarudzika zvinhu ndeye aluminium oxide, uye silicon carbide inosarudzwa kucheka zvisiri ferrous uye zvisiri-metallic zvinhu.Nekuti aruminiyamu oxide zvinhu zvinoshandiswa kucheka simbi zvinhu hazvibatike kemikari nemakemikari zvikamu musimbi, inobatsira pakucheka.Masimbi asina simbi uye asina ferrous ane yakaderera makemikari kuita, nepo silicon carbide zvinhu zvine yakaderera kemikari kuita zvichienzaniswa nealuminium, zvirinani kucheka kuita, kushoma kutsva, uye kushoma kupfeka.

3, Kusarudzwa kwegranularity

Kusarudza chiyero chepakati chepakati chinobatsira pakucheka.Kana kupinza kuchidikanwa, coarser saizi yezviyo inogona kusarudzwa;Kana kucheka kunoda kurongeka kwepamusoro, abrasive ine yakatsetseka particle size inofanira kusarudzwa.
