Ukucisha okubili-okuphakathi: I-workpiece eshisiselwe izinga lokushisa lokucima kuqala ipholiswe endaweni ye-Ms endaweni yokucisha enamandla okupholisa enamandla, bese idluliselwa endaweni yokupholisa kancane ukuze iphole kuya kuzinga lokushisa elilingana negumbi ukuze kuzuzwe amazinga okushisa okupholisa ahlukene, futhi kukhona Izinga lokupholisa elifanele lokucisha. Isetshenziselwa izimo eziyinkimbinkimbi noma ama-workpieces amakhulu enziwe ngensimbi ephezulu ye-carbon steel ne-alloy steel, futhi insimbi yensimbi ye-carbon nayo isetshenziswa kakhulu kule ndlela. Imithombo yokupholisa evame ukusetshenziswa amanzi-amafutha, amanzi-nitrate, umoya-manzi, umoya kawoyela. Ngokuvamile, amanzi asetshenziswa njengendlela yokucima ukupholisa okusheshayo, uwoyela noma umoya usetshenziswa njengendlela yokucisha epholile kancane, futhi umoya usetshenziswa kancane.
