Uretse ibisabwa ku buryo bunoze bwa analog block mu bice by'igikoresho cyo kugenzura ikinyabiziga, ubuziranenge bw'uburebure bw'ibindi bice byemejwe ko ari plus cyangwa minus.±0.01MM, kandi imiterere ishobora kuba hagati ya 0.1mm yo kongera cyangwa gukuraho. Iyo uburyo bw'ubuto bukoreshejwe, bunatunganywa hakurikijwe 0.1mm yo kongera cyangwa gukuraho isanzwe n'uburebure hakurikijwe ubushobozi bwa 0.01mm yo kongera cyangwa gukuraho.

Uburyo bwo gutunganya agakoresho k'igenzura ry'imodoka bufite ibice bitatu, intebe y'agakoresho n'agakoresho k'ibumoso n'iburyo gafite imiterere ingana. Mbere yo gutunganya, ibikoresho by'ibikoresho byinjira birabanza kumenyekana, hanyuma hakamenyekana imiterere y'inyuma y'ibikoresho byinjira, niba hari 0.3 ~ 0.5.mm.Ingano y'imashini isya itangira gukubitwa. Kugira ngo byorohereze gutunganya nyuma, hagomba gukorwa aho hagomba kurebwa. Umwobo w'imashini ushyirwamo ukoresheje icyuma cya 2.5mm. Umwobo w'imashini ugomba gucibwa no kurangizwa nyuma yo kurangiza gusya. Nyuma y'uko imashini isya irangiye, gukubita byoherezwa. Ubushyuhe, gukomera ni HRC45° C ~ 48° C, ibifunga bisanzwe byatumijwe ku isoko ntibikomera, Kugira ngo harebwe igihe ibikoresho bimara, ibice byose by'icyuma birakomera kandi birangizwa nyuma yo gushyuha. Menya ko ubugari bw'intebe ipfundikiye n'agace k'inyuma bigomba kunozwa kugira ngo±0.01MM, kandi gutunganya insinga birarangira nyuma yo kurangiza. Umuyoboro n'umwobo wo gupfuka ni byo nyabyo. Mu gihe uhuza, ugomba kwita ku mwanya uhuye. Kugira ngo ibumoso n'iburyo bitazanyeganyezwa nyuma yo kurangiza ubufatanye, hakorwa uburyo bwiza bwo gupfuka.
