Izixhumi ziyizingxenye ezibalulekile ekuxhumekeni kwemishini, futhi ikhwalithi yazo ithinta ngokuqondile ukuphepha nokuthembeka kwezinto zokusebenza. Ukuqinisekisa ukuthi izinto zokubopha zihlangabezana namazinga asebenzayo, kufanele zihlolwe ngokuphelele ngenqubo yokuhlola ehlelekile.
Ukuhlolwa kokubukeka kuyisinyathelo sokuqala. Abahloli ngokubuka noma ngengilazi ekhulisayo bahlola indawo yokubopha ukuze bathole amaphutha afana nokuqhekeka, ukuklwebheka, ukugqwala, nama-burrs. Bagxila ekuhloleni ukuthi izintambo ziqinile futhi azilimalanga, nokuthi ukushintsha phakathi kwekhanda ne-shank kuhamba kahle, baqinisekise ukuthi awekho amaphutha asobala wokukhiqiza.
Ukulinganisa kobukhulu kusebenzisa amathuluzi okulinganisa anembayo njengama-caliper, ama-micrometer, namageji ochungechunge ukuze kuqinisekiswe ngokobuningi amapharamitha okubopha okubalulekile afana nobubanzi, ubude, nosayizi wentambo. Ukuhlola kufanele kuthobelane ngokuqinile nemidwebo yedizayini noma amazinga emboni (afana ne-ISO, i-DIN, ne-GB) ukuze kuqinisekiswe ukubekezelelana kobukhulu kungaphakathi kwemikhawulo eyamukelekayo. Kuzinto zokubopha{2}ezinjongo ezikhethekile, amapharamitha engeziwe afana nogqinsi lwekhanda nokujula kwe-groove nawo kufanele akalwe.
Ukuhlolwa kwempahla yemishini kuyisinyathelo esibalulekile. Umshini wokuhlola i-tensile usetshenziselwa ukuhlola amandla e-fastener aqine futhi unikeze amandla ukuze kuqinisekiswe ukuthi umthamo waso{1}wokuthwala uhlangabezana nezimfuneko zebanga lezinto ezibonakalayo. Ukuhlolwa kokuqina (okufana nokuqina kwe-Rockwell noma i-Brinell) nakho kwenziwa ukuze kuqinisekiswe ukuthi inqubo yokwelapha ukushisa iyahlangabezana nezindinganiso. Kuzinto zokubopha ezifana namabhawudi namantongomane, i-torque{4}}ukuhlola ukulayisha kuqala noma isikulufu-ekuhlolweni nakho kuyadingeka ukuze kuhlolwe ukusebenza kwenhlangano yazo.
Ukuhlola -okungonakalisi kulungele izinhlelo zokusebenza eziyisidingo. Ukuhlolwa kwezinhlayiyana kazibuthe (MT) noma ukuhlola kwe-penetrant (PT) kusetshenziselwa ukuthola indawo noma eduze-nokuqhekeka komhlaba; ukuhlolwa kwe-ultrasonic (UT) noma ukuhlolwa kwe-radiographic (RT) kusetshenziselwa ukuthola amaphutha angaphakathi, ikakhulukazi-amandla aphezulu noma izibopheli ezibucayi.
Ukuhlolwa kokwelashwa okungaphezulu kuhlanganisa ukukala ukujiya kokujiya (okufana nokufaka i-galvanizing), ukuhlolwa kwesifutho sikasawoti (ukumelana nokubola), nokuhlaziywa kwezinkomba zemvelo (njengokuqukethwe kwe-chromium ene-hexavalent) ukuze kuqinisekiswe ukumelana nokugqwala nokuhambisana.
Ekugcineni, yonke idatha yokuhlola ihlanganiswa ibe umbiko futhi isayinwe futhi iqinisekiswe abahloli bekhwalithi. Imikhiqizo engalungile ihlukaniswa futhi imbangela iyalandelelwa. Imikhiqizo efanelekayo kuphela engafaka ukupakishwa noma ukuhlanganisa. Le nqubo emisiwe iqinisekisa ngempumelelo ukuvumelana kwekhwalithi nokuphepha kobunjiniyela kwezixhumi.
