Sarudzo yebhainda uye abrasive yakabatana zvakanyanya.Semuenzaniso, kushandiswa kweCBN kunowanzoda vhiri rekukuya kuti richengete chimiro charo chisina kuchinjika panguva yekushandiswa uye kuti rirege kubviswa kubva muchina chishandiso kusvika chapedzwa zvachose.Sezvo thermal conductivity yeCBN yakanaka kwazvo, zviri nani kushandisa simbi bond.Iko kusanganiswa kwezviviri kunopa mamiriro ekucheka kunotonhora.Nokuti kupisa kwekucheka kunoparidzirwa kuburikidza neabrasive uyekugayavhiri, uye ndokutakurwa neinotonhorera, inokurumidza kupfuura kupinda muworkpiece.
Kune marudzi maviri esimbi bond: electroplating uye sintering.Electroplated grindingmavhiri haana kuchekwa, anogadzirwa muchimiro chakarurama pakutanga uye anoshandiswa kusvika apera.Sintered simbi yekukuya mavhiri anowanzo kuchekwa nemagetsi spark, obva aiswa pamaturusi emuchina senge electroplated kugaya mavhiri.Iyo radial runout ye sintered uye electroplated ekukuya mavhiri akaiswa pachirukwa achaita isingasviki 0.0125mm.Kune simbi yakasungirirwa mavhiri ekukuya, zvakakosha zvakanyanya kuderedza spindle runout.
Nokuti chinhambwe icho zviyo zvinoputika zvinobuda kubva pachisungo idiki kwazvo, kana iyo runout inosvika 0.025mm, imwe mugumo wekugayavhiri richaremerwa, zvichikonzera kupera zvakanyanya, uye imwe magumo icharemerwa uye ichiri kupinza.Mamwe mavhiri ekukuya ane electroplated anogona kugadzira diki contour arc radius (inenge 0.125mm).Nekudaro, iyo arc radius yeakawanda electroplated mavhiri ekukuya yakakura kupfuura 0.5mm.Kazhinji, electroplated kugaya mavhiri anoshandiswa pakukuya-kumhanya, nepo simbi sintered kugaya mavhiri akakodzera kukuya zvinhu zvedongo.
Monolithic simbi yakasungwavhiri rekukuyaine huwandu hudiki hwekuchinjika kune vibration, runout, inotonhorera kuyerera uye mamwe mamiriro ekushanda.Kana iyo kuomarara kweguyo, workpiece uye fixture isina kunaka, kana kutakurwa kwechishandiso chekare chisiri muchimiro chakanaka, uye pasina chiyero chekuenzanisa pamushini wemuchina, kushandisa electroplated grinding vhiri pasi pechiitiko ichi kuchatungamira matambudziko muhupenyu hwebasa regumbo rekukuya, workpiece kupera uye kuumbwa kwepamusoro.Zvinoenderana nekudengenyeka uye kugadzikana kwechishandiso chemuchina uye mamwe mamiriro chaiwo, dzimwe nguva zviri nani kushandisa resin yakasungirirwa mavhiri ekukuya.
Resin bond ine simba rekudzimisa simba kune vibration.Ehe, midziyo uye nguva inobatanidzwa mukugadzirisa uye kupfekedzwa kweresin yakasungirirwa mavhiri ekukuya kuchawedzera mutengo.Ceramic bond ndiyo inonyanya kushandiswa.Nekuda kwekuti vhiri rekukuya rakasungwa rine maburi, mvura yekucheka inogona kunyatsopinda muarc yekukuya, uye kune maburi mahombe ekubata marara akapfeka.Panguva imwecheteyo, iyo ceramic yakasungirirwa vhiri rekukuya inogona kugadzirwa nyore kune iyo chaiyo chimiro uye yakarodzwa nekushandisa maturusi edhaimani.
