Ubukana bw'aho icupa riherereye bushobora gufasha gusuzuma ubukana bw'icupa, bityo bikagufasha kumenya niba icupa rifite imbaraga zikenewe, bityo uburyo bwo gupima ubukana bwa Vickers ni uburyo bufasha gusuzuma ubwiza bw'icupa.
Isosiyete ipima ubukana bwa Vickers yo muri Shandong Shancai / Laizhou Laihua ikora isuzuma ubukana bwa Vickers ishobora gukora isuzuma ry'ubukana ku bice byasutswe cyangwa ahantu ho gusudira. Mu gihe isuzuma ubukana bwa point yo gusudira, ibipimo by'ingingo nyinshi bizakorwa ku ntera runaka uvuye ku nkengero y'icyitegererezo cyangwa hejuru y'point yo gusudira. Nyuma yo kubona intero y'ingingo nyinshi, agaciro k'ubukana gashobora gupimwa hakoreshejwe gupima guhoraho kandi hakaboneka imbonerahamwe y'inyuguti.
Mu gihe ukoresha icyuma gipima ubukana bwa Vickers kugira ngo upime ibice byayo bisutswe, ugomba kwita ku bintu bikurikira:
1. Uburebure bw'icyitegererezo: Mbere yo gupima, dusya isudi igiye gupimwa kugira ngo ubuso bwayo burusheho kuba bwiza, budafite urwego rwa okiside, imyanya n'ibindi bitagira inenge.
2. Ku murongo wo hagati w'umushongi, fata akantu gato ku buso bugose buri mm 100 kugira ngo upime.
3. Guhitamo imbaraga zitandukanye zo gupima bizatanga ibisubizo bitandukanye, bityo tugomba guhitamo imbaraga zikwiye zo gupima mbere yo gupima.
Igipimo cy’ubukana bw’ubutare gifite ibisabwa kugira ngo ishusho y’ikizamini irangire neza, bigomba gutegurwa neza hakurikijwe icyitegererezo cy’icyuma.
Ihame ry’igerageza ry’ubukomere bw’udukoko mu buryo bwo gupima ubukomere bw’udukoko ni rimwe rwose n’iry’ubukomere bw’udukoko bwa Vickers, ariko umutwaro ukoreshwa ni muto ugereranije n’ubukomere bw’udukoko bwa Vickers bufite umutwaro muto, akenshi ukaba uri munsi ya garama 1000, kandi aho bivamo ni mikoroni nke gusa kugeza kuri mikoroni ebyiri nke, bityo isuzuma ry’ubukomere bw’udukoko ritanga uburyo bworoshye cyane bwo kwiga imiterere y’imiterere y’agace gashobora kwinjiramo. Rikoreshwa cyane mu kumenya ubukomere bwa buri cyiciro ku buso no mu gace gashobora kwinjiramo.
Ikimenyetso cy'ubukomere buto gikunze kugaragazwa na HV, kandi ihame ryacyo n'uburyo bwo kugipima bisa n'uburyo bwa Vickers hardness. Sisitemu yo gupakira, sisitemu yo gupima hamwe n'ubuhanga bwo gupima ubukomere buto birasaba cyane kurusha iy'igerageza ubukomere buto bwa Vickers. Muri iki gihe, igerageza ubukomere buto bukoreshwa cyane mu bikoresho bito, kandi kubera ko ubwiyongere bushobora kugera ku nshuro 400, akenshi ikoreshwa nka mikorosikopi yoroshye ya metallographic.
Mu gihe cyo gukoresha, hagomba kwitabwaho umutwaro, mikorometero n'indanga y'icyuma gipima ubukana bw'ubukana bw'ubukorikori, bigomba kugenzurwa mbere yo kubikoresha, kandi agace k'ubukana gakoreshwa mu kumenya neza agaciro kabyo.
Igipimo cy’ubukomere bw’imashini gikoresha umutwaro mu gikorwa cyo gupima neza kandi kimwe uko bishoboka kose, nta ngaruka cyangwa guhindagurika. Kugira ngo hamenyekane neza ko ibisubizo by’ikizamini ari ukuri, ubusanzwe ni ngombwa gupima inshuro nyinshi mu bice bitandukanye, no gushaka agaciro mpuzandengo gasobanura agaciro k’ubukomere bw’urwego rw’ikizamini cyo gupima cyangwa igice cy’imashini. Ku rwego rw’ikizamini cyo kwinjira gikoreshwa ku bushyuhe bwinshi, ubukomere bwacyo bushobora gupimwa hakoreshejwe igipimo cy’ubukomere bw’imashini cyo gupima ubushyuhe bwinshi.
