Mu ma workshop komwe zoletsa zida zimatsutsana ndi mapulojekiti akuluakulu, HSS 42411/2 Chobowola Chochepetsedwa cha ShankMndandandawu ukubwera ngati njira yosinthira mawonekedwe. Zopangidwa kuti zigwirizane ndi mphamvu zokhazikika za chuck ndi kufunikira kwakukulu kwa kubowola, zida zatsopanozi zimapatsa mphamvu akatswiri azitsulo, akalipentala, ndi opanga zinthu kuti athe kuthana ndi mabowo a 13-60mm pogwiritsa ntchito mabowo a tsiku ndi tsiku—sipafunikira kukweza makina.
Kuchepetsa Shank Geometry: Kuchulukitsa kwa Torque
Pakati pa chitukukochi pali kapangidwe ka shank kotsatizana, komwe kamachepetsa kukula kwa grip kufika pa 1/2" (12.7mm) pamene kumasunga kukula kwa dayamita mpaka 60mm. Kapangidwe kabwino aka kakutsegula zabwino zitatu zosintha masewera:
Kuboola Mogwirizana: Kumakwanira machuck wamba a 1/2" pa ma drill amanja, ma bench drill, ndi ma CNC routers—zipangizo zomwe sizingathe kunyamula ma shank a diameter yonse.
Kusamutsa Mphamvu Yowonjezera: Shank yofupikitsidwayo imachepetsa kugwedezeka, zomwe zimapangitsa kuti 25% ikhale yokhazikika poyerekeza ndi ma adapter ofikira kutali.
Kuchepetsa Kugwedezeka: Kusanthula kwa zinthu zomaliza kumatsimikizira kuti kugwedezeka kwa harmonic kumachepa ndi 30% pobowola chitsulo cholimba mozama.
Zitoliro zozungulira za 32° helix angle—zokonzedwa bwino kuti zitulutse chip mwachangu—zimaletsa kuwotcherera zinthu mu aluminiyamu, pomwe nsonga yogawanika ya 135° imachotsa mabowo oyambira mumatabwa ndi mapulasitiki.
Moyo wa nthawi zitatu poyerekeza ndi HSS yachizolowezi mu chitsulo chotuwa (kuboola kosalekeza, 800 RPM)
Chotchinga cha kutentha cha 600°C chisanachitike kutentha—chofunika kwambiri pa chitsulo chosapanga dzimbiri ndi titaniyamu
Kuchepetsa kukangana kwa 40% kudzera m'malo opukutidwa a chitoliro, kuchepetsa kukhuthala kwa chingamu mu pulasitiki yofewa
Kusinthasintha kwa Zinthu: Chimodzi, Makampani Asanu ndi Awiri
Kuchokera m'masitolo okonza magalimoto mpaka m'malo opangira sitima, shank yochepetsedwa ya 1/2" imakula m'madera osiyanasiyana:
Kupanga Zitsulo: Kuboola mabowo a 20mm m'mafelemu a galimoto pogwiritsa ntchito zida zopanda zingwe (pamafunika kuyikapo choziziritsira ndi chifunga)
Kukonza Matabwa: Kumiza mabowo a dowel a 60mm m'mitengo ya oak popanda kung'ambika
Kuikapo pulasitiki: Kumapanga ma venti opanda burr mu nkhungu za polycarbonate pa 3,000 RPM
Kupanga/Kumanga: Kulowa m'malo mwa macheka a mabowo a PVC payipi ndi machubu amagetsi
Pazochitika zokonza zadzidzidzi, kusinthasintha kumeneku n'kofunika kwambiri—anthu odziwa bwino ntchito yokonza ma turbine a mphepo akuboola madoko a chingwe a 45mm pogwiritsa ntchito ma drill onyamulika a maginito.
Mayeso Ogwira Ntchito: Shank Yaing'ono, Zotsatira Zazikulu
Kuwonjezeka kwa Chiwongola dzanja cha Chakudya: Kulowa mwachangu kwa 18% muzitsulo zachitsulo za ASTM A36 poyerekeza ndi zodulira za annular
Kusunga Ndalama: 60% yotsika mtengo kuposa njira zina zochepetsera shank zomwe zingagwire mabowo >30mm
Kulondola: ± 0.1mm kulekerera m'mabowo 100 mu ntchito za CNC
Kusunthika: Kumathandiza kuboola mabowo a 40mm mu chitsulo cha I-beams pogwiritsa ntchito ma drill opanda zingwe a 18V
Pa malo ogulitsira ntchito, izi zikutanthauza kuti ndalama zokwana $5,000 pamwezi zimasungidwa pobwereka zida zogwirira ntchito zazikulu zobowola.
Ma Protocol Ogwira Ntchito: Kudziwa Bwino Kayendedwe ka Ntchito
Kuti muwonjezere phindu la ndalama zomwe mumapeza:
Chilango cha Kuzizira:
Zitsulo: Mafuta osungunuka (kuchuluka kwa 8–10%)
Mapulasitiki: Mpweya woponderezedwa
Matabwa: Kudula kouma kumaloledwa
Malangizo a Liwiro:
Chitsulo Chopangidwa: 500–700 RPM
Aluminiyamu: 1,500–2,500 RPM
Pulasitiki ya ABS: 3,000+ RPM
Kuboola Peck: Chotsani kuya kulikonse kwa 2xD kuti zipsu zichotsedwe mu zitsulo
Mapeto
HSS 4241 1/2" Reduced Shank Drill Bit si chida chokha—ndi choyezera zachuma. Mwa kuswa mgwirizano wachikhalidwe pakati pa kukula kwa dzenje ndi kukula kwa zida, imapatsa mphamvu malo ogwirira ntchito ang'onoang'ono kuti apikisane ndi osewera mafakitale. Kwa ogwira ntchito yokonza, imachotsa zochitika za "sangathe kuboola"; kwa opanga, imatsegula luso lotha kugwira ntchito mwachangu. Munthawi yovuta yogwira ntchito, yankho la shank iyi yocheperako limatsimikizira kuti nthawi zina, kugwira pang'ono kumapereka kukula kwakukulu.
Nthawi yotumizira: Meyi-20-2025
