Ithini indinganiso kazwelonke yobubanzi bokubekezelela usayizi wezingxenye zokujova zemoto?
Izinga likazwelonke lobubanzi bokubekezelela usayizi wezingxenye zomjovo wezimoto yi-GB/T 14486-2008 “Ukubekezelela Usayizi Wezingxenye Ezibunjwe Ngepulasitiki”.Leli zinga licacisa ukubekezelelwa kwe-dimensional kwezingxenye ezibunjiwe zepulasitiki, futhi lifanele izingxenye ezibunjiwe zepulasitiki ezijovwayo, ezicindezelwe nezijovwe.
Ngokwezinga likazwelonke, uhla lokubekezelela usayizi wezingxenye zomjovo wezimoto luhlukaniswe ngamamaki A no-B.Izidingo zokunemba zekilasi A ziphezulu, zilungele izingxenye zokujova ezinembayo;Izidingo zokunemba zeBanga B ziphansi, zilungele izingxenye ezijwayelekile zomjovo.Ibanga elithile lokubekezelelana limi kanje:
(1) Ukubekezelela komugqa:
Ubukhulu bomugqa bubhekisela kubukhulu ngobude.Ezingxenyeni ezibunjiwe zomjovo we-Class A, ububanzi bokubekezelelana bosayizi womugqa ± 0.1% kuya ku-±0.2%;Ezingxenyeni ezibunjiwe zomjovo we-Class B, ububanzi bokubekezelela ubukhulu bomugqa ±0.2% ukuya ku-±0.3%.
(2) Ukubekezelelana kwe-engeli:
Ukubekezelelana kwe-engeli kubhekisela ekuchezukeni kwe-engeli ekubumbeni nasekubekezeleleni isikhundla.Ezingxenyeni ezibunjiwe zomjovo we-Class A, ukubekezelelana kwe-Angle kungu-±0.2° kuya ku-±0.3°;Ezingxenyeni ezibunjiwe zomjovo Wekilasi B, ukubekezelelwa kwe-engeli kungu-±0.3° ukuya ku-±0.5°.
(3) Ukubekezelelana kwefomu kanye nesikhundla:
Ukubekezelelwa kwefomu nesikhundla kuhlanganisa ukujikeleza, ukuqina kwe-cylindricity, parallelism, ukuma, njll. Ezingxenyeni zomjovo wesigaba A, ukubekezelelwa kwefomu nokubekezelela kunikezwa ngokwesigaba K ku-GB/T 1184-1996 “Ukubekezelela Komumo Nesikhundla okungacacisiwe Ivelu Lokubekezelela”;Ezingxenyeni zomjovo wekilasi B, ukubekezelelwa kwefomu nokubekezelela kunikezwa ngokuya ngekilasi M ku-GB/T 1184-1996.
(4) Ubulukhuni bobuso:
Ubulukhuni bobuso bubhekisela ezingeni lokungalingani kwe-microscopic endaweni emshinini.Ezingxenyeni ezibunjiwe zomjovo wekilasi A, ubulukhuni obungaphezulu bungu-Ra≤0.8μm;Ezingxenyeni ezibunjiwe zomjovo wekilasi B, ubulukhuni obungaphezulu bungu-Ra≤1.2μm.
Ngaphezu kwalokho, kwezinye izimfuneko ezikhethekile zezingxenye zomjovo wezimoto, njengamaphaneli wezinsimbi, ikhonsoli emaphakathi, njll., izimfuneko zokubekezelelwa kohlangothi zingase zibe phezulu, futhi zidinga ukulawulwa ngokuya ngezidingo ezithile zomkhiqizo.
Ngamafuphi, indinganiso kazwelonke yobubanzi bokubekezelela izingxenye zemijovo yezimoto yi-GB/T 14486-2008 “Ukubekezelela Dimensional kwezingxenye ezibunjiwe zePlastiki”, elicacisa izidingo zokubekezelelana kobukhulu, ukwakheka nokubekezelelana kwesikhundla kanye nobulukhuni bobuso bepulasitiki ebunjiwe. izingxenye.Ekukhiqizeni kwangempela, kuyadingeka ukulungisa nokwandisa ngokuya ngezidingo zomkhiqizo kanye nokwakheka kwesikhunta ukuze kuqinisekiswe ukuthi izingxenye zomjovo wemoto ziyahlangabezana nezidingo.
