Vickers kuuma HV (makamaka poyezera kuuma kwa pamwamba)
Gwiritsani ntchito diamondi square cone indenter yokhala ndi katundu wokwanira 120 kg ndi ngodya yapamwamba ya 136 ° kuti mutsike pamwamba pa zinthuzo ndikuyesa kutalika kwa diagonal ya indentation. Njirayi ndi yoyenera kuwunika kuuma kwa zida zazikulu zogwirira ntchito komanso zigawo zakuya pamwamba.
Leeb hardness HL (choyesa cholimba)
Njira yolimba ya Leeb imagwiritsidwa ntchito poyesa kuuma kwa zinthu. Mtengo wa kuuma kwa Leeb umatsimikiziridwa ndi kuyeza liwiro lobwereranso la thupi lomwe limakhudzidwa ndi sensa ya hardness pokhudzana ndi kuthamanga kwamphamvu pamtunda wa 1mm kuchokera pamwamba pa chogwirira ntchito panthawi yomwe ikukhudzidwa, ndiyeno kuchulukitsa chiŵerengerochi ndi 1000.
Ubwino:The Leeb hardness tester, yotengera mfundo ya Leeb hardness, yasintha njira zoyesera zachikhalidwe. Kukula kwakung'ono kwa sensa yolimba, yofanana ndi cholembera, imalola kuyesa kulimba kwa m'manja pazida zogwirira ntchito mbali zosiyanasiyana pamalo opangira. Kuthekera uku ndikovuta kuti oyesa kuuma pakompyuta ena agwirizane.
Pali zida zosiyanasiyana zopangira makina, kutengera mtundu wazinthu zomwe zikugwiritsidwa ntchito. Zida zomwe zimagwiritsidwa ntchito kwambiri ndizotsamira kumanzere, kutsamira kumanja, ndi kutsamira kwapakati, monga momwe zikusonyezedwera mu chithunzi chomwe chili pansipa, kutengera mtundu wa abwana omwe amapangidwa. Kuphatikiza apo, zida za tungsten carbide zokhala ndi zokutira zotentha kwambiri zitha kugwiritsidwa ntchito kudula chitsulo kapena zinthu zosavala.
2. Kuwunika kwa chida
Yang'anani mosamala mpeni wodulidwa musanaugwiritse ntchito. Ngati mukugwiritsa ntchito zitsulo zothamanga kwambiri (HSS), nolani mpeniwo kuti muwonetsetse kuti ndi wakuthwa. Ngati mukugwiritsa ntchito mpeni wolekanitsa wa carbide, onetsetsani kuti tsambalo lili bwino.
3. Kwezani kukhazikika kokhazikika kwa mpeni wodula
Kuuma kwa chida kumakulitsidwa ndikuchepetsa kutalika kwa chida chotuluka kunja kwa turret. Ma diameter akulu kapena zolimba zogwirira ntchito ziyenera kusinthidwa kangapo pamene chida chikudula muzinthu panthawi yolekanitsa.
Pazifukwa zomwezo, kupatukana kumachitidwa nthawi zonse pafupi ndi chuck momwe zingathere (kawirikawiri pafupifupi 3mm) kuti muwonjezere kuuma kwa gawolo panthawi yopatukana, monga momwe tawonetsera pachithunzichi.
4. Gwirizanitsani chida
Chidacho chiyenera kugwirizanitsidwa bwino ndi x-axis pa lathe. Njira ziwiri zodziwika bwino zochitira izi ndikugwiritsa ntchito chotchinga choyika zida kapena choyezera choyimba, monga momwe zikuwonekera pachithunzichi.
Kuti muwonetsetse kuti mpeni wodulira umakhala wolunjika kutsogolo kwa chuck, mutha kugwiritsa ntchito chipika cha geji chokhala ndi malo ofanana. Choyamba, masulani turret, kenako gwirizanitsani m'mphepete mwa turret ndi chipika cha geji, ndipo potsiriza, limbitsaninso zomangirazo. Samalani kuti geji isagwe.
Kuonetsetsa kuti chidacho ndi perpendicular chuck, mungagwiritsenso ntchito dial gauge. Gwirizanitsani choyezera choyimba ku ndodo yolumikizira ndikuyiyika panjanji (osayenda motsatira njanji; konzani pamalopo). Lozani cholumikizira pa chida ndikuchisuntha motsatira x-axis mukuyang'ana zosintha pa dial gauge. Cholakwika cha +/-0.02mm ndichovomerezeka.
5. Onani kutalika kwa chida
Mukamagwiritsa ntchito zida pazingwe, ndikofunikira kuyang'ana ndikusintha kutalika kwa mpeni wotsatsira kuti ukhale pafupi ndi mzere wapakati wa spindle momwe mungathere. Ngati chida cholekanitsa sichili pamtunda wapakati, sichingadulidwe bwino ndipo chikhoza kuonongeka panthawi ya Machining.
Monga mipeni ina, mipeni yogawanitsa iyenera kugwiritsa ntchito lathe level kapena wolamulira kuti nsonga yake ikhale pakatikati.
6. Onjezerani mafuta odulidwa
Mukamagwiritsa ntchito galimoto yokhazikika, musagwiritse ntchito kudyetsa basi, ndipo onetsetsani kuti mumagwiritsa ntchito mafuta ambiri odula, chifukwa kudula kumatulutsa kutentha kwambiri. Choncho, kumatentha kwambiri pambuyo podula. Pakani mafuta odula kwambiri kunsonga ya mpeni wodula.
7. Kuthamanga kwapamwamba
Podula pagalimoto wamba, wodulayo nthawi zambiri amayenera kudulidwa pa 60% ya liwiro lomwe likupezeka mu bukhuli.
Chitsanzo:Custom mwatsatanetsatane Machiningndi chodulira carbide kuwerengera liwiro la 25.4mm m'mimba mwake aluminiyamu ndi 25.4mm m'mimba mwake wofatsa zitsulo workpiece.
Choyamba, yang'anani liwiro lovomerezeka, High Speed Steel (HSS) Parting Cutter (V-Aluminium ≈ 250 ft / min, V-Steel ≈ 100 ft / min).
Kenako, werengani:
N Aluminiyamu [rpm] = 12 × V / (π × D)
=12 mu/ft × 250 ft/mphindi / ( π × 1 mu/rpm)
≈ kuzungulira kwa 950 pamphindi
N chitsulo [rpm] = 12 × V / (π × D)
=12 mu/ft × 100 ft/mphindi / ( π × 1 mu/rpm)
≈ kuzungulira kwa 380 pamphindi
Zindikirani: N aluminiyamu ≈ 570 rpm ndi N zitsulo ≈ 230 rpm chifukwa cha kuwonjezera pamanja kwa kudula mafuta, omwe amachepetsa liwiro la 60%. Chonde dziwani kuti awa ndi ma maximums ndipo chitetezo chiyenera kuganiziridwa; Choncho zing'onozing'ono zogwirira ntchito, mosasamala kanthu za kuwerengera, sizingadutse 600RPM.
Ngati mukufuna kudziwa zambiri, chonde omasuka kulumikizananiinfo@anebon.com.
Ku Anebon, timakhulupirira kwambiri "Kasitomala Woyamba, Wapamwamba Nthawizonse". Pokhala ndi zaka zopitilira 12 mumakampani, takhala tikugwira ntchito limodzi ndi makasitomala athu kuti tiziwapatsa ntchito zabwino komanso zapaderacnc kutembenuza zigawo, CNC machined mbali zotayidwa, ndizigawo zoponya kufa. Timanyadira makina athu othandizira othandizira omwe amaonetsetsa kuti zinthu zili bwino komanso zotsika mtengo. Tathetsanso ogulitsa omwe ali ndi khalidwe loipa, ndipo tsopano mafakitale angapo a OEM agwirizana nafenso.
