Yintoni naUmatshini wokuhombisa?
Umatshini wokuhombisa sisixhobo esichanekileyo somatshini wokwenza isinyithi esisetyenziselwa ukuphucula ifom yejometri, ukuthungwa komphezulu, kunye nokuchaneka kwe-dimensional ye-workpiece ngokwenza inkqubo ye-honing. Isebenzisa amatye abrasive (honing izixhobo) ukuba zixhonywe mandrel kwaye ijikeleziswa lo gama ngaxeshanye ishukunyiswa ngendlela elawulwayo isindululo reciprocating ngaphakathi bore okanye ngaphaya komhlaba.
Yintoni iHoning?
Ukuhloniphayinkqubo yokugqiba apho iseti yeamatye abrasiveisusa izinto ezincinci kakhulu (imicrons) ukusuka kumphezulu wentsimbi yentsimbi ukuphucula:
Ukuchaneka komgangatho(ukuzisa imingxuma kubungakanani obuchanekileyo kunye nokungqukuva)
Ukugqitywa komphezulu(ukufumana indawo egudileyo okanye enqamlezileyo)
Ukulungiswa kwejometri(ukususa i-taper, ovality, okanye ukugqwesa emva komatshini wangaphambili njengokugrumba, ukubuyisela kwakhona, okanye ukudika)
Kutheni Usebenzisa umatshini wokuhombisa?
Ukuhoya kusetyenziswa xaukuchaneka okugqithisileyo kunye{0}}nomgangatho ophezulu wokugqitywa komphezuluziyafuneka, ngakumbi kwiindawo apho:
Ukunyamezela okuqinileyo (± 2-5 microns) kuyimfuneko.
Ubume obuthile bomphezulu (njengeipateni yokuwelakwiisilinda ze-injini) ziyafuneka ukuze kugcinwe ukuthambisa.
Umbhobho okanye umphezulu kufuneka ubeingqukuva, ithe tye, kwaye ayinamanqaku encokoishiywe zezinye iinkqubo zoomatshini.
Ngokufutshane: Ukugrumba, ukukruqula, kunye nokuphinda kufumaneke ukuchaneka okanye umgangatho womphezulu ofunekayo - ukuhoya sisisombululo.
Chaza iNkqubo yokuHlonipha
