Mabuloko anu achitsulo akukunamizani.
Osati mwadala. Koma patatha miyezi isanu ndi umodzi ndikugwiritsa ntchito pansi m'sitolo—kupopera madzi ozizira, kutentha kumasintha pakati pa kusintha kwa m'mawa ndi masana, kugwera pang'onopang'ono pa mbale yachitsulo—boloko la “10mm” limenelo lingakhale 10.0003mm. Kapena 9.9997mm. Ndipo ngati mukugwiritsa ntchito ma tolerance a 5-micron, zolakwika zazing'ono zimenezo zimapangika kukhala zidutswa zotayidwa.
Ili ndi vuto losamveka bwino lomwe palibe amene amalankhulapo pankhani yokonza zinthu molondola.
Izi ndi zomwe zimachitika ndi ma gauge achitsulo m'malo opangira zinthu.
Chitsulo chimawononga. Ngakhale "zopanda banga" zimatha kuwononga zinthu zikagwiritsidwa ntchito ndi zinthu zoziziritsira, mafuta odulira, kapena chinyezi chambiri pakapita nthawi. Nkhope zogwirira ntchito zikayamba kuwononga ngakhale pang'ono, khalidwe lanu lopotoka limasintha. Mabuloko sakukhazikika bwino. Kutalika kumayandama.
Chitsulo chimawonongeka. Nthawi iliyonse mukapotoza mulu wa gauge block, mukuchotsa zinthu zazing'ono m'maso. Pambuyo pozungulira mokwanira—kutengera momwe mwagwiritsira ntchito, mwina ma stack mazana angapo—kulondola kwa muyeso kumachoka chifukwa cha kulolerana. Satifiketi yanu yoyezera zaka ziwiri zapitazo mwina siingasonyeze zomwe mukuyezera lero.
Chitsulo chimachita maginito. Mu malo oyezera zinthu ndi malo opangira makina a CNC, kusokoneza kwa maginito kuchokera ku zida zapafupi kungakhudze momwe chitsulo chimagwirira ntchito. Sikuti nthawi zonse, osati modabwitsa—koma mu ntchito zolondola kwambiri, “zosachuluka” zimakhala zochuluka kwambiri.
Chitsulo chimakula ndi kutentha. Inde, chitsulo chili ndi kuchuluka kwa kutentha komwe kumadziwika, ndipo ma laboratories abwino ndi omwe amachititsa izi. Koma kusinthasintha pang'ono kwa kutentha nthawi zonse patsiku lopanga kumapanga kusagwirizana pang'ono koma kwenikweni kwa muyeso.
Zipangizo zoyezera za ceramic zimapewa mavuto onsewa.
Ndipo si matsenga—ndi chemistry ndi physics zomwe zimachita ntchito yawo.
Tengani zirconia ceramic. Kulimba kwa 1200-1450 HV1, poyerekeza ndi mwina 700-800 HV ya chitsulo cholimba. Izi zikutanthauza kuti ma gauge blocks opangidwa kuchokera ku zirconia amakumana ndi gawo limodzi mwa magawo khumi a kuchuluka kwa kuwonongeka. Mu selo imodzi yolembedwa yopukutira molondola, kusinthana ndi ma gauge blocks a ceramic kunawonjezera nthawi yowerengera kuyambira miyezi ingapo mpaka chaka chilichonse. Dzimbiri lomwe linkavutitsa zitsulo zawo mu utsi woziziritsa linatha.
Kapangidwe kake kosakhala ndi maginito kamasintha kwambiri ntchito zina. Zirconia ili ndi mphamvu yolimbana ndi pamwamba yoposa 10^14 Ω·cm—yoteteza magetsi, yopanda maginito konse. Izi zimachotsa zinthu zokopa maginito zomwe zingasokoneze zotsatira za kuwunika. Ngati mukuyeza zigawo za bearing kapena kugwira ntchito pafupi ndi zida zamaginito, izi ndizofunikira.
Ndipo khalidwe la kutentha ndi lothandiza modabwitsa. Kuchuluka kwa kutentha kwa Zirconia kuli pafupifupi 1 × 10 ^ - 5 / °C. Izi zikufanana ndi chitsulo, zomwe zikutanthauza kuti mawerengedwe anu ochiritsira kutentha safunikira kukonzedwanso kwathunthu. Koma ceramic siimapangitsa kutentha mofanana, kotero kutentha mkati mwa chidacho chokha kumakhala kochepa. Kuwerenga komwe mumapeza mukatha masekondi 30 mutakhudza kumakhala kokhazikika, sikumasuntha pamene chidacho chikufanana pang'onopang'ono.
Tsopano, funso lenileni: zirconia kapena alumina?
Zirconia imapambana chifukwa cha kulimba kwake. Ili ndi chomwe chimatchedwa "kulimba kwa kusintha" - ikapanikizika, imasinthasintha pang'ono gawo lomwe limakana kufalikira kwa ming'alu. Izi zimapangitsa kuti ikhale yokhululuka kwambiri ngati mwangozi mwagwetsa chipika cha gauge. Alumina ndi yolimba koma yofooka kwambiri; kugunda kungayambitse kusweka.
Mphamvu ya kupindika kwa zirconia ya pafupifupi 1100 MPa ndi pafupifupi katatu kuposa ya alumina. Ngati zida zanu zikugwira ntchito molakwika, zirconia imakhala yolekerera kwambiri.
Koma alumina ili ndi malo ake. Ndi yotsika mtengo, imakhala yolimba kwambiri (HV 1200+), ndipo pa ntchito zomwe mukufuna kutentha kochepa kwambiri—monga metrology ya kuwala—CTE yotsika ya alumina ingakhale yopindulitsa. Masitolo ena odziwa bwino kuwala amakonda alumina makamaka chifukwa imathamanga pang'ono ndi kutentha.
Komabe, pa ntchito zambiri zogwiritsira ntchito makina olondola, zirconia ndi yabwino kwambiri. Ubwino wake ndi wolimba, ndipo mtengo wake umabwerera chifukwa cha nthawi yayitali yogwira ntchito komanso kuchepa kwa ma calibration.
Kodi izi zimawoneka bwanji pochita?
Pakupanga ma bearing, ma ceramic gauge pini amawunika kukula kwa ma race diameter amkati ndi akunja tsiku lonse. Ma ceramic pini ali pamalo amenewo? Kuwonekera kwa coolant, kuipitsidwa kwa tinthu tachitsulo, kugwira ntchito nthawi zonse. Ma ceramic pini sachita dzimbiri, samakopa zinyalala zachitsulo, ndipo kuuma kwakukulu kumatanthauza kuti nkhope zoyezera zimakhalabe zolekerera kwa nthawi yayitali. Wopanga ma bearing wina adati chiŵerengero chawo chosinthira ma pin owunikira chatsika ndi pafupifupi 80% atasintha kupita ku ceramic.
M'masitolo ogulitsa zinthu zopangidwa ndi nkhungu ndi zida, ma V-blocks a ceramic ndi m'mbali molunjika amayesa kuya kwa dzenje, makulidwe a tsamba, ndi kukhazikika kwa zinthu. Mbali yosasamalira bwino ndi yayikulu apa—palibe mafuta, palibe dzimbiri, palibe nkhawa ngati mbale ya m'mphepeteyo yasiyidwa usiku wonse. Igwetseni, itsukeni, igwiritseni ntchito.
Pakupanga zinthu zowunikira, zida zoyezera za ceramic zimakhudza magalasi ndi ma prism omwe sangakandane. Kukhwima kwa pamwamba pa ma blocks abwino a ceramic gauge—Ra ≤ 0.2 micrometers—sikuwononga galasi lowala lopukutidwa. Ndipo chifukwa ceramic ndi yopanda mankhwala, palibe chiopsezo cha kuipitsidwa kwa ayoni yachitsulo kukhudza zokutira za lens kapena transmissivity.
Mu semiconductor ndi zamagetsi, mphamvu zosagwiritsa ntchito maginito, komanso zosagwiritsa ntchito maginito zimachotsa kusokoneza kwa makina oyezera omwe amagwiritsa ntchito capacitive komanso induction. Zipangizo zachitsulo zomwe zili pafupi ndi zinthu zofewa zimatha kuyambitsa mavuto osiyanasiyana omwe ndi ovuta kuwazindikira.
Zinthu zingapo zothandiza zomwe muyenera kudziwa.
Kusankha magiredi kumagwira ntchito ngati ma block achitsulo: Giredi 0, 1, 2, ndi 3, malinga ndi miyezo ya ISO 3650. Mapulogalamu ambiri opangira zinthu molondola amafunikira Giredi 0 kapena Giredi 1. Ngati mukugwira ntchito yomwe sikufuna kulondola kotereku, musamalipire.
Kusunga zinthu n'kosavuta kuposa chitsulo. Palibe mafuta, palibe zophimba zoletsa dzimbiri, kapena kabati yowongolera chinyezi. Kungosunga zinthu zoyera ngati zili ndi chikwama. Sizofooka, koma kuzikonza kumafupikitsa moyo wa chida chilichonse.
Kukonza zinthu ndikofunikirabe. Sitima yadothi siichotsa kugwedezeka konse—imangokhala yochedwa kwambiri kuposa chitsulo. Kukonza zinthu pachaka ndi njira yodziwika bwino yogwiritsira ntchito zipangizo zopangira; masitolo ena amawonjezera nthawi yogwiritsira ntchito mpaka miyezi 18-24 ngati ntchitoyo ndi yopepuka.
Mtengo wake ndi weniweni koma ndi wokwanira. Yembekezerani kulipira mwina 30-50% kuposa zitsulo zofanana ndi zitsulo. Koma mukaganizira za nthawi yayitali yowerengera, kuchepa kwa nthawi yosinthira, komanso kulephera konse chifukwa cha dzimbiri, ndalama zonse zomwe mumagwiritsa ntchito pazaka zisanu nthawi zambiri zimakhala zabwino kapena zabwino.
Nayi kufananiza mwachidule komwe kukuwonetsa izi momveka bwino.
Seti yanu ya chitsulo choyezera, momwe mungagwiritsire ntchito, momwe pansi pa shopu imagwirira ntchito:
- Kukonza miyezi 3-6 iliyonse chifukwa cha kuwonongeka ndi dzimbiri
- Kusintha mabuloko omwe amagwiritsidwa ntchito kwambiri zaka 2-3 zilizonse
- Zolakwika zina zoyezera chifukwa cha dzimbiri kapena kuwonongeka kwa pamwamba
- Kutsuka ndi kudzola mafuta tsiku ndi tsiku kuti mupewe dzimbiri
Kugwiritsa ntchito komweko, ma ceramic gauge blocks:
- Kukonza miyezi 12-18 iliyonse
- Kusintha kokha ngati kwawonongeka mwakuthupi
- Khalidwe loyezera lokhazikika komanso lodziwikiratu
- Pukutani, sungani, mwamaliza
Kusiyana kumeneku kwa ntchito ndi kwenikweni. Ndipo m'sitolo yotanganidwa komwe katswiri wanu wa QC ali kale wochepa, kuchotsa chinthu chimodzi chokonzera zinthu kuchokera mu equation ndikofunikira kwambiri.
Kudziwa ngati zida zoyezera za ceramic zili zomveka pa ntchito yanu kumadalira momwe zinthu zilili.
Ngati mukugwiritsa ntchito njira zolimba, kugwira ntchito m'malo ovuta, kapena kuthera nthawi yochuluka mukumenyana ndi kukonza ma gauge block, switch iyi mwina ndi yoyenera kuifufuza. Yambani ndi seti imodzi—kit yoyambira ya gauge block yomwe mumakonda kwambiri—ndipo onani momwe imagwirira ntchito poyerekeza ndi momwe mumagwirira ntchito panopa.
Masitolo ambiri omwe amayesa ceramic sagwiritsanso ntchito chitsulo.
