Ibikoresho byawe by'icyuma birakubeshya.
Ntabwo ari nkana. Ariko nyuma y'amezi atandatu yo gukoresha hasi mu iduka—gukoresha ibyuma bikonjesha, ubushyuhe buhinduka hagati ya mugitondo na nyuma ya saa sita, rimwe na rimwe bigana ku isahani y'icyuma gikozwe mu cyuma—iyo "mm 10" ishobora kuba 10.0003mm. Cyangwa 9.9997mm. Kandi niba ukoresha ubushobozi bwo gupima mikoroni 5, ayo makosa mato yiyongeramo ibice byacitse.
Iki ni ikibazo cy'agacerere nta muntu uvugaho mu bijyanye no gutunganya neza ibikoresho.
Dore uko bigenda mu by'ukuri ku bipimo by'icyuma mu bikorwa.
Icyuma kirangirika. Ndetse n'ibipimo "bidakoze neza" bishobora gutobora no kwangirika iyo bihuye n'ibikoresho bikonjesha, amavuta akatwa, cyangwa ubushuhe bwinshi uko igihe kigenda gihita. Iyo amaso akoze neza, ndetse n'imyitwarire yawe yo gutobora irahinduka. Ibice ntibikigaragara neza. Uburebure burahindagurika.
Icyuma kirashira. Igihe cyose uvangavanze agace k'icyuma gipima, uba ukuyemo uduce duto tw'ibikoresho mu maso. Nyuma y'ingendo zihagije—bitewe n'uko wakoresheje, wenda uduce tubarirwa mu magana—ubuziranenge bw'ibipimo buhita bugabanuka bitewe n'ubushobozi bwo kwihanganira. Icyemezo cyawe cyo gupima cyo mu myaka ibiri ishize gishobora kutagaragaza icyo upimye uyu munsi.
Icyuma gikoresha rukuruzi. Muri laboratwari z’ibipimo n’ibigo bikora imashini za CNC, ingaruka mbi ku bikoresho biri hafi aho zishobora kugira ingaruka ku mikorere y’icyuma. Si buri gihe, si ku buryo butangaje—ariko mu buryo bunonosoye cyane, “si byinshi” bishobora kuba byinshi cyane.
Ibyuma bikura bitewe n'ubushyuhe. Yego, icyuma gifite igipimo cyo kwaguka k'ubushyuhe kizwi, kandi laboratwari nziza ni zo zibitera. Ariko ihindagurika rito ry'ubushyuhe mu gihe cy'umunsi wo gukora rituma ibipimo bito ariko nyabyo bihindagurika.
Ibikoresho byo gupima bya ceramic bikuraho ibi bibazo byose.
Kandi si ubumaji—ni ubutabire na fiziki gusa bikora akazi kabyo.
Fata zirconia ceramic. Ubukomere bwa 1200-1450 HV1, ugereranije na 700-800 HV ku byuma bikomeye. Ibyo bivuze ko ibipimo bya gauge brickes bikozwe muri zirconia bihura na kimwe cya cumi cy'umuvuduko wo kwangirika. Mu gice kimwe cyanditseho uburyo bwo gusya neza, guhindura ibipimo bya gauge brickes byongereye igihe cyo gupima kuva buri mezi make kugeza buri mwaka. Ingese yateraga ibyuma byabo mu gihu gikonjesha yashize.
Imiterere idakoresha ingufu za rukuruzi ihindura ibintu bimwe na bimwe. Zirconia ifite ubushobozi bwo guhangana n'ubuso burenga 10^14 Ω·cm—irinda ubushyuhe mu buryo bw'amashanyarazi, ntabwo ikoresha ingufu za rukuruzi rwose. Ibyo bikuraho ibintu bikurura ingufu za rukuruzi bishobora guhindura ibisubizo by'igenzura. Niba upima ibice by'icyuma gipima amashanyarazi cyangwa ukorera hafi y'ibikoresho byo gucukura ingufu za rukuruzi, ibi ni ingenzi.
Kandi imyitwarire y'ubushyuhe iratangaje. Igipimo cya Zirconia cyo kwaguka k'ubushyuhe kiri kuri 1 × 10 ^ - 5 / °C. Ibyo bisa nkaho ari icyuma, bivuze ko imibare yawe yo kwishyura ubushyuhe idakeneye ivugurura ryuzuye. Ariko ceramic ntabwo ikora ubushyuhe kimwe, bityo ubushyuhe buri mu gikoresho ubwacyo ni buke. Ishusho ubona nyuma y'amasegonda 30 yo gukoraho irahamye, ntabwo igenda buhoro buhoro kuko igikoresho kigenda gihwana buhoro buhoro.
Noneho, ikibazo nyacyo: zirconia cyangwa alumina?
Zirconia iratsinda bitewe n'ubukomere bwayo. Ifite icyo bita "gukomera mu mpinduka" - iyo ihutishijwe, ihinduka gato mu buryo butuma idakwirakwira neza. Ibi bituma irushaho kuba nziza iyo uguye ku gipimo cy'icyuma gipima. Alumina irakomeye ariko irushaho kuba mbi; ingaruka zishobora gutera gucikagurika.
Ingufu za Zirconia zo kuzunguruka zingana na 1100 MPa zingana na gatatu ugereranyije n'iza alumina. Niba ibikoresho byawe bikoreshwa nabi, zirconia iba nziza cyane.
Ariko alumina ifite umwanya wayo. Irahendutse, iracyakomeye cyane (HV 1200+), kandi ku bijyanye n'ikoreshwa aho ukeneye kwaguka k'ubushyuhe gato cyane—nk'isuzuma ry'amatara—ingufu nke za alumina zo mu bwoko bwa CTE zishobora kuba ingirakamaro. Amwe mu maduka acuruza amatara akoresha uburyo bworoshye akunda alumina cyane cyane kuko idahindagurika cyane bitewe n'ubushyuhe.
Ku bikorwa byinshi byo gutunganya neza, zirconia niyo ikoreshwa cyane. Inyungu yo kuramba ni iy'ukuri, kandi ikiguzi cy'ikiguzi cyishyurwa iyo umuntu amaze igihe kirekire kandi akazi kagakoreshwa gake.
Ibi bisa bite mu bikorwa?
Mu gukora ibyuma bipima uburebure bw'icyuma, ibyuma bipima uburebure bw'icyuma bigenzura uburebure bw'icyuma imbere n'inyuma umunsi wose. Ibintu bipima uburebure bw'icyuma muri ubwo buryo? Guhura n'ibikoresho bikonjesha, kwanduza uduce tw'icyuma, no gufata neza. ibyuma bipima uburebure bw'icyuma ntibitera kwangirika, ntibikurura imyanda y'icyuma, kandi ubukana bwinshi butuma ubuso bupimisha buguma mu buryo bwo kwihanganira ibintu igihe kirekire. Umwe mu bakora ibyuma bipima uburebure yavuze ko igipimo cyo gusimbuza ibyuma bipima cyagabanutseho hafi 80% nyuma yo guhindura ibyuma bipima uburebure bw'icyuma.
Mu maduka acuruza ibikoresho by'ibumba n'ibibumbano, ibice bya V bya ceramic n'impande zigororotse bipima uburebure bw'aho hantu, ubugari bw'icyuma, n'uburyo gishyirwa mu mwanya wacyo. Aha hantu nta kwita ku kintu ni ingenzi cyane—nta mavuta yasizwe, nta gusuzuma ingese, nta guhangayikishwa no kumenya niba icyo gice cy'inyuma cyarasigaye hanze mu ijoro ryose. Kijugunye, gisukure, ugikoreshe.
Mu gukora ibice by'indorerwamo, ibikoresho byo gupima indorerwamo bikora ku mboni n'ama prismu adashobora gushwanyaguzwa. Ubukana bw'ubuso bw'ibipimo by'indorerwamo nziza ya ceramic—Ra ≤ mikorometero 0.2—ntibwangiza ikirahuri cy'indorerwamo gikozwe mu buryo bwa shimi. Kandi kubera ko ceramic idakora neza mu buryo bwa shimi, nta ngaruka zo kwanduza iyoni y'icyuma zigira ingaruka ku irangi ry'indorerwamo cyangwa ku ikwirakwizwa ry'indorerwamo.
Mu bikoresho bya semiconductor na elegitoroniki, imiterere idakoresha ingufu za rukuruzi ikuraho ingaruka mbi ku buryo bwo gupima bushingiye ku bushobozi bwo gupima no ku gupima hakoreshejwe induction. Ibikoresho by'icyuma biri hafi y'ibice by'ingenzi bishobora guteza ibibazo byinshi bigoye kubibona.
Ibintu bike bifatika bikwiye kumenywa.
Guhitamo amanota bikora nk'ibipimo by'icyuma: Icyiciro cya 0, 1, 2, na 3, hakurikijwe amahame ya ISO 3650. Porogaramu nyinshi zo gutunganya neza zikenera Icyiciro cya 0 cyangwa Icyiciro cya 1. Niba ukora akazi kadasaba ubwo buryo bwo gutunganya neza, ntukishyure.
Kubika biroroshye kurusha icyuma. Nta mavuta, nta bipfunyika bibuza ingese, nta kabati gacungwa n'ubushuhe gakenewe. Gusa ububiko burasukuye mu gasanduku kazanwa. Ntabwo byoroshye, ariko kubitunganya bigabanya igihe cyo kubaho k'igikoresho icyo ari cyo cyose.
Gupima biracyakenewe. Ceramic ntikuraho burundu guhindagurika kw'amazi—igenda buhoro cyane kurusha icyuma. Gupima buri mwaka ni ibisanzwe ku bikoresho bikoreshwa mu musaruro; amwe mu maduka yimura amezi 18-24 iyo ikoreshwa ari rito.
Igiciro cy'ubwishingizi ni ukuri ariko kirahagije. Tega kwishyura mbere y'igihe amafaranga angana na 30-50% kurusha ibyuma bingana nabyo. Ariko iyo ugereranyije n'igihe cyo gupima igihe kirekire, igihe cyo gusimbuza kigabanuka, kandi nta kwangirika gushingiye ku ingese, ikiguzi cyose cyo gutunga mu myaka itanu akenshi kivamo neza cyangwa kirenze.
Dore igereranya ryihuse ribigaragaza neza.
Seti yawe y'icyuma gipima, uko ikoreshwa, imiterere y'aho iduka rikorera:
- Gupima buri mezi 3-6 bitewe no kwangirika no kwangirika
- Gusimbuza ibiti bikoreshwa cyane buri myaka 2-3
- Amakosa yo gupima rimwe na rimwe aturuka ku kwangirika cyangwa kwangirika k'ubuso
- Gusukura no kwisiga amavuta buri munsi kugira ngo hirindwe ingese
Ikoreshwa rimwe, ibipimo bya ceramic:
- Gupima buri mezi 12-18
- Gusimbuza gusa iyo byangiritse ku mubiri
- Imyitwarire ihamye kandi ishoboka yo gupima
- Hanagura, bika, warangije
Iryo tandukaniro mu mikorere ni ukuri. Kandi mu iduka rihuze aho umuhanga mu by'ikoranabuhanga (QC) wawe yamaze kugabanuka, gukuraho ikintu kimwe cyo kubungabunga muri icyo kigereranyo ni ingenzi cyane.
Niba ibikoresho byo gupimisha bya ceramic bifite ishingiro mu mikorere yawe biterwa n'imimerere yawe yihariye.
Niba ukoresha ubushobozi bwo kwihanganira ibintu byinshi, ukorera ahantu hagoye, cyangwa umara igihe kinini urwanya uburyo bwo kubungabunga bloki, birashoboka ko iyi switch ikwiye gusuzumwa. Tangira n'itsinda rimwe—agakoresho k'ibanze k'agakoresho gapima mu rugero rusanzwe—maze urebe uko gakora ukurikije uko ugenda ubu.
Amaduka menshi agerageza gukoresha ibumba ntabwo asubira mu byuma.
