Uburyo bwo gutunganya ubuso bw'icyuma kitagira umugese bufite NO.1, 2B, No. 4, HL, No. 6, No. 8, BA, TR hard, Rerolled bright 2H, polished bright n'ibindi birangira ku buso, nibindi.

NO.1: Ubuso bwa No.1 buvuga ubuso buboneka binyuze mu gutunganya ubushyuhe no gusya nyuma yo gusya icyuma kitagira umugese. Ni ugukuraho igipimo cya okiside y'umukara cyakozwe mu gihe cyo gutunganya ubushyuhe no gusya hakoreshejwe gusya cyangwa ubundi buryo busa nabwo. Ubu ni ubuso bwa No.1 butunganya ubuso. Ubuso bwa No.1 ni umweru w'ifeza kandi butagira umugese. Bukoreshwa cyane cyane mu nganda zirwanya ubushyuhe kandi zirwanya ingese zidakenera ubushyuhe, nko mu nganda zikora inzoga, inganda zikora imiti n'ibikoresho binini.

2B: Ubuso bwa 2B butandukanye n'ubuso bwa 2D kuko bukozwe neza hakoreshejwe akantu koroshye, bityo bukaba bwiza kurusha ubuso bwa 2D. Ubukana bw'ubuso bw'ubushyuhe Igipimo cya Ra gipimirwa n'igikoresho ni 0.1 ~ 0.5μm, ari nabwo bukunze gukoreshwa cyane mu gutunganya. Ubu bwoko bw'ubuso bw'icyuma kitagira umugese ni bwo bukoreshwa cyane, bukwiriye imirimo rusange, bukoreshwa cyane mu nganda za shimi, impapuro, peteroli, ubuvuzi n'izindi, kandi bushobora no gukoreshwa nk'urukuta rw'inyubako.

Irangi rikomeye rya TR: Ibyuma bitagira umushongi bya TR nabyo byitwa icyuma gikomeye. Ibyiciro byabyo by'icyuma ni 304 na 301, bikoreshwa ku bicuruzwa bisaba imbaraga nyinshi n'ubukomere, nk'imodoka za gari ya moshi, imikandara yo gutwara ibintu, amasoko na gasket. Ihame ni ugukoresha imiterere y'icyuma gitagira umushongi cya austenitic kugira ngo wongere imbaraga n'ubukomere bw'icyuma hakoreshejwe uburyo bukonje nko kuzunguruka. Ibikoresho bikomeye bikoresha igice gito kugeza ku icumi ku ijana by'izunguruka ryoroheje kugira ngo bisimbuze ubugari bworoheje bw'ubuso bw'ibanze bwa 2B, kandi nta gufunga bikorwa nyuma yo kuzunguruka. Kubwibyo, ubuso bukomeye bwa TR bw'ibikoresho bikomeye ni ubuso buzunguruka bukonje.

Irabagirana mu buryo bwa 2H: Nyuma yo kuyizunguruka, urupapuro rw'icyuma kitagira umugozi ruzatunganywa neza cyane. Urupapuro rushobora gukonjeshwa vuba n'umurongo ukomeza gukurura. Umuvuduko w'urupapuro rw'icyuma kitagira umugozi ku murongo ni hafi metero 60 ~ 80m / min. Nyuma y'iyi ntambwe, ubuso buzaba bufite uburebure bwa saa 2.

No.4: Ubuso bwa No.4 ni ubuso bwiza busesuye kandi burusha ubuso bwa No.3. Buboneka no gusiga irangi ku gice cy'icyuma gikonje gikonje gifite ubuso bwa 2 D cyangwa 2 B nk'ishingiro hanyuma ugasiga irangi ukoresheje umukandara usanzwe ufite ingano ya 150-180# Ubuso bukozwe mu mashini. Uburemere bw'ubuso bwa Ra bupimwe n'igikoresho ni 0.2 ~ 1.5μm. Ubuso bwa No.4 bukoreshwa cyane mu bikoresho bya resitora n'ibikoni, ibikoresho by'ubuvuzi, imitako y'inyubako, ibikoresho byo mu gikoni, nibindi.

HL: Ubuso bwa HL bukunze kwitwa impera y'umusatsi. Igipimo cya JIS cyo mu Buyapani kivuga ko umukandara wo mu bwoko bwa 150-240# ukoreshwa mu gusiga irangi ku buso busanzwe bumeze nk'ubusatsi buboneka. Mu gipimo cya GB3280 cyo mu Bushinwa, amabwiriza ntasobanutse neza. Impera y'umusatsi wa HL ikoreshwa cyane mu gushariza inyubako nko mu byuma bitanga umusatsi, mu byuma bitanga umusatsi, no mu byuma bitanga umusatsi.

No.6: Ubuso bwa No. 6 bushingiye ku buso bwa No. 4 kandi burushaho gusigwa hakoreshejwe uburoso bwa Tampico cyangwa ibikoresho byo gusimbuza bifite ingano ya W63 yagenwe n'ibipimo bya GB2477. Ubu buso bufite ubwiza bw'icyuma kandi bufite ubushobozi bworoshye. Ishusho ni nto kandi ntigaragaza ishusho. Kubera ubu bwiza, bukwiriye cyane gukora inkuta z'amarido y'inyubako n'imitako y'inyubako, kandi bukoreshwa cyane nk'ibikoresho byo mu gikoni.

BA: BA ni ubuso buboneka hakoreshejwe ubushyuhe bwinshi nyuma yo gukonja. Ubushyuhe bwinshi ni ugushyira mu kirere gikingira gikingira ko ubuso budakonja kugira ngo bugumane ubwiza bw'ubuso bukonja, hanyuma ugakoresha agakoresho ko koroshya neza kugira ngo urumuri rurusheho kuba rwiza. Ubu buso buri hafi y'indorerwamo, kandi ubukana bw'ubuso bwa Ra bupimwe n'igikoresho ni 0.05-0.1μm. Ubuso bwa BA bufite uburyo bwinshi bwo gukoresha kandi bushobora gukoreshwa nk'ibikoresho byo mu gikoni, ibikoresho byo mu rugo, ibikoresho by'ubuvuzi, ibice by'imodoka n'imitako.

No.8: No.8 ni ubuso bukozwe mu ndorerwamo bufite ubushobozi bwo kugarura urumuri rwinshi budafite uduce duto two gukaraba. Inganda zitunganya ibyuma bitagira umugozi nazo ziyita plaque za 8K. Muri rusange, ibikoresho bya BA bikoreshwa nk'ibikoresho fatizo byo kurangiza indorerwamo binyuze mu gusya no gusiga irangi gusa. Nyuma yo kurangiza indorerwamo, ubuso buba bukozwe mu buryo bw'ubugeni, bityo bukoreshwa cyane mu mitako y'irembo ry'inyubako no mu mitako y'imbere.
