Mu dziko la ntchito zachitsulo, kulondola ndiye chinthu chofunikira kwambiri. Limodzi mwa mafunso omwe amafunsidwa kwambiri ndi ogulitsa ndi ogwiritsa ntchito ndi awa: "Kodi RPM yolondola ya drill bit yanga ndi iti?" Kukhazikitsa liwiro loyenera ndiko kusiyana pakati pa dzenje loyera ndi chida chowonongeka. Ngati liwiro lili lalikulu kwambiri, kukangana kumabweretsa kutentha kwambiri, zomwe zimapangitsa kuti nsonga "yoyaka". Ngati ili yotsika kwambiri, mphamvu imachepa, ndipo mumakhala pachiwopsezo chothyoka bit chifukwa cha torque yambiri.
Kumvetsetsa Zoyambira: Kuchepetsa Liwiro vs. RPM
Musanawerenge liwiro, muyenera kumvetsetsa Cutting Speed Vc. Izi zikuyimira liwiro lomwe m'mphepete mwa chobowoleracho mumadutsa pamwamba pa workpiece.
Ngakhale kuti Liwiro Lodulira limatsimikiziridwa ndi zinthu zomwe zili mu workpiece, RPM (Revolutions Per Minute) ndi momwe mumasinthira makina anu osindikizira kapena CNC.
Fomula ya Masamu Yolondola
Kuti mupeze RPM yeniyeni yofunikira pa ntchito yanu yeniyeni, mainjiniya aluso amagwiritsa ntchito njira yokhazikika iyi:
Deta Yofotokozera Yokhazikika ya Makampani
Deta yotsatirayi ikuchokera pa miyezo ya uinjiniya yodziwika padziko lonse lapansi (monga ISO 3685 ndi DIN 1414) ya zida za High-Speed Steel (HSS). Makhalidwe awa ndi muyezo wapadziko lonse wa chitetezo ndi magwiridwe antchito a zitsulo.
Malangizo Abwino: Mukamagwiritsa ntchito ma drill bits a HSS-Co (Cobalt), nthawi zambiri mutha kuwonjezera liwiroli ndi 20% chifukwa cha kukana kutentha kwa chipangizocho.
Zinthu Zitatu Zofunika Kwambiri Zomwe Zimakhudza Zotsatira Zanu
Kupatula njira imeneyi, zinthu zitatu zakunja zidzatsimikizira kupambana kwanu:
- Kusamalira Kutentha ndi Mafuta
Kutentha ndiye mdani wamkulu wa HSS. Kugwiritsa ntchito mafuta odulira kapena choziziritsira chapamwamba kwambiri kumakupatsani mwayi wogwiritsa ntchito kumapeto kwa RPM yovomerezeka. Popanda mafuta odzola, muyenera kukhala kumapeto "kotetezeka" kwa sikelo kuti chitsulo chisafe.
- Kuchotsa Chip (Njira ya "Peck")
Pa mabowo akuya, RPM iyenera kulinganizidwa ndi kuchotsa zipsera. Ngati zipsera (zopindika zachitsulo) sizingatuluke mu zitoliro, zidzatsekeka ndikutentha kwambiri. Tikukulimbikitsani "kuboola zipsera" - kubweza zipsera nthawi ndi nthawi kuti muchotse zinyalala.
- Kukhazikika kwa Makina
Ngati mukugwiritsa ntchito chobowolera chamagetsi chogwiridwa ndi dzanja, nthawi zonse gwiritsani ntchito RPM yocheperako kuposa mtengo wowerengedwa. Zipangizo zogwiridwa ndi dzanja zimakhala ndi kugwedezeka kwambiri komanso kukhazikika kochepa kuposa chobowolera chokhazikika, zomwe zimawonjezera chiopsezo cha "kuyenda" kapena kusweka.
Mapeto
Kugwiritsa ntchito RPM yoyenera ndiyo njira yosavuta yowonjezera moyo wa zinthu zanu za Jiacheng Tools. Mwa kutsatira miyezo yapadziko lonse lapansi iyi, mukutsimikiza kuti zidutswa zanu za HSS drill zimakhala zakuthwa, mabowo anu amakhala olondola, komanso ndalama zomwe mumagwiritsa ntchito popanga zimakhala zochepa.
