Iwe unoziva aya mazwi: Helix angle, point kona, huru yekucheka muganho, mbiri yenyere? Kana zvisiri, iwe unofanirwa kuramba uchiverenga. Isu tichapindura mibvunzo yakaita seiyi: Ndeipi yechipiri yekucheka? Chii chinonzi helix angle? Vanokanganisa sei kushandiswa kuri mukushandisa?
Nei zvichikosha kuti uzive zvinhu izvi: zvigadzirwa zvakasiyana nzvimbo dzakasiyana siyana pane chishandiso. Nechikonzero ichi, kusarudzwa kweiyo twist kudhiraivha nechimiro chakakodzera chakanyanya kukosha pakukwevera kwemhedzisiro.
Ngatitarisei zvinhu zvisere zvakakosha zvechisere. Point angle
Kuti uzadzise iyo yakanakisa yekucheka kuita mune dzakasiyana zvinhu, zvese zvisere zvinhu zvinofanirwa kuenderana kune mumwe nemumwe.
Kuenzanisira izvi, isu tinofananidza zvinotevera zvinotevera zvinodhonza kune mumwe nemumwe:
Poindi angle
Iyo poindi angle iri mumusoro weiyo twist drill. Iyo angle yakayerwa pakati pemapepa maviri makuru ekucheka kumusoro. Pfungwa angle inodikanwa kuti ive pakati peiyo twist kudhiraivha mune izvo zvinyorwa.
Iyo diki iyo poindi angle, zviri nyore centering mune izvo zvinyorwa. Izvi zvinoderedzawo njodzi yekutsvedza pane yakakombama nzvimbo.
Iyo yakakura iyo nzvimbo yakakora, kupfupika nguva yekubatira. Nekudaro, kudzvinyirira kwepamusoro kwekutaurirana kunodiwa uye kuiswa mune izvo zvinyorwa zvakaoma.
Geometrically yakarongedzwa, kadiki kadiki kona zvinoreva kuti yakareba yekucheka mativi, nepo hombe point kona inoreva kupfupi mapfupi ekucheka mativi.
Main Kucheka Edges
Iyo huru yekucheka edges inotora pamusoro peiyo chaiyo yekudhirowa maitiro. Kureba kwekucheka mativi kuve nekucheka kwepamusoro kwekucheka kuenzaniswa nemipendero yepfupi yekucheka, kunyangwe kana mutsauko uri mudiki kwazvo.
Iyo twist drill inogara ine maviri makuru ekucheka matura akabatana neakacheka chisel chisel.
Cheka chisel kumucheto
Iyo yakacheka chisel kumadokero iri pakati peiyo yekudhirowa tip uye isina kuchema. Nekudaro, zvakakosha pakuvaka kweiyo twist dring, sezvo ichibatanidza iyo mbiri huru yekucheka mipendero yekucheka.
Iyo yakatemwa chisel yemucheto ndeyekupinda mukati mezvinyorwa uye zvine simba kumanikidzwa uye kupokana pane izvo zvinyorwa. Izvi zvivakwa, izvo zvisina kunaka pakudhiraivha, zvinoguma nekuwedzera kupisa chizvarwa uye kuwedzera simba rekushandisa simba.
Nekudaro, izvi zvivakwa zvinogona kuderedzwa neinonzi "kuonda".
Point cuts uye point kuonda
Iyo poindi yakatetepa kuderedza iyo akacheka chisel yemucheto kumusoro kweiyo twist kudhiraivha. Iyo inotetepa inoguma mukudzikiswa kwakakura kweiyo mauto ekupokana mune izvo zvinyorwa uye nekudaro kuderedzwa kweiyo yakakodzera yekupa simba.
Izvi zvinoreva kuti kutetepa ndiyo chinhu chinonzwisisika chekuzadzisa mune izvo zvinyorwa. Inovandudza kuteya.
Iyo Yakasiyana-siyana Point Finnings yakaenzana muHin 1412 Maumbirwo. Maumbirwo akanyanya kuwanda ndiyo helical point (chimiro n) uye kupatsanura nzvimbo (chimiro c).
NHOROONDO YEMAHARA (Groove Mbiri)
Nekuda kwebasa rayo sechiteshi, iyo nhoroondo yeyepfeka inosimudzira chip chekubata uye kubvisa.
Iyo yakawedzera iyo groove mbiri, iri nani chipekuro uye kubviswa.
Kumberi chip
Wide groove profiles iri furati, dzakatetepa dzemahara dzakadzika. Kudzika kweiyo Groove Mbiri inosarudza iyo ukobvu kweiyo Drill Core. Flat groove profiles inobvumira yakakura (gobvu) core core diamita. Yakadzika Groove profiles inobvumira zvidiki (zvakaonda) core core diamita.
Musimboti
Iyo core brickness ndiyo nzira yekusarudzika yekugadzikana kweiyo twist kudhiraivha.
Twist anodhiraivha neakakura (gobvu) core core Diameter ane yakakwira kugadzikana uye saka yakakodzera kune yakakwira torques uye zvakaoma zvinhu. Ivo zvakare vakanyatsokodzera kushandiswa mune ruoko kudhiraivha sezvavanonyanya kuramba kuita vibrations uye vanozotevera mauto.
Kuti vafambise kubviswa kwemachipisi kubva kuGroove, iyo Core Brickness inowedzera kubva kuChilling tip kune shank.
Kutungamira chamfers uye sekondari yekucheka matura
Iwo maviri ekufambisa machira ari pamiti. Iyo inopinza pasi chamfers inoshanda pamusoro pemativi emativi eiyo borehole uye rutsigiro kutungamirirwa kweiyo twist kudhiraivha mune yakadhirowa gomba. Hunhu hwemasvingo emabhoriyamu hunotsamira pane yekufambisa chamfers.
Iyo yechipiri yekucheka kumucheto inoumba shanduko kubva kuChidimbu Chamfers kusvika Groove Mbiri. Inosunungura uye inocheka machipisi yakanamatira kune izvo zvinyorwa.
Kureba kweiyo nzira dzekutungamira uye sekondari yekucheka mativi inotsamira zvakanyanya pane helle angle.
Helix Angle (Spiral Angle)
Chinhu chakakosha chekudhirowa twist ndeye helle angle (spiral kona). Iyo inosarudza maitiro echiputi chechip.
Yakakura Helix Angles inopa kubviswa kunobudirira kwekubvisa kwakapfava, refu-chipping zvinhu. Diki helix angles, kune rumwe rutivi, anoshandiswa kune yakaoma, pfupi-chipping zvinhu.
Twist Dries ine idiki diki helix kona (10 ° - 19 °) ine yakakwana spiral. Mukudzoka, twist Drill Swith A Helini Helix Agle (27 ° - 45 °) Iva neyakagadzirwazve (pfupi) spiral. Twist kufambisa neyakajairika spiral ine helix angle ye19 ° - 40 °.
Mabasa ehunhu hwekushandisa
Pakutanga kutarisa, nyaya yetsvina twist inoita kunge yakanaka yakaoma. Ehe, kune zvakawanda zvikamu uye zvinhu zvinoparadzanisa kudhiraivha kwemhepo. Nekudaro, maitiro mazhinji anoenderana.
Kuti uwane iyo yekurudyi yekukwira kumusoro, iwe unogona kumutsidzira iwe pachako kune yako application mune yekutanga nhanho. Iyo Din Manual yedhirivhari uye CounterseryKs inotsanangura, pasi din 1836, chikamu chemapoka ekushandisa muzvikamu zvitatu n, h, uye w:
Mazuva ano hauzombowana aya matatu emhando n, h, uye w, uye w Pser pamusika, mhando dzakarongedzwa zvakasiyana nekuita kuti twist dress yezvinhu zvakakosha. Saka, mafomu ekuurayiwa akaumbwa ayo ane mazita ekutumidza mazita asina kugadzirwa mune din bhuku. PaMSK iwe uchawana kwete chete mhando n asi zvakare mhando dze Uni, UTL kana VA.
Mhedziso uye Pfupiso
Iye zvino iwe unoziva izvo zvikamu zveiyo twist kudhirowa kukurudzira maitiro ekukwevera. Tafura inotevera inokupa iwe kuongorora kwezvinhu zvakakosha zvemabasa azvo.
| Basa | Zvimiro |
|---|---|
| Kucheka Kuita | Main Kucheka Edges Iyo huru yekucheka edges inotora pamusoro peiyo chaiyo yekudhirowa maitiro. |
| Hupenyu hweBasa | NHOROONDO YEMAHARA (Groove Mbiri) Iyo profitle yedombo rinoshandiswa sechiteshi chehurongwa hwechiputi chekunyudza uye kubviswa uye, saka, chinhu chakakosha chehupenyu hwesistm twist dring. |
| Application | Point angle & helix angle (spiraral kona) Iyo poindi angle uye iyo helle angle ndiyo yakakosha zvinhu zvekushandisa mune zvakaoma kana zvakapfava zvinhu. |
| Centuring | Point cuts uye point kuonda Pfungwa dzinocheka uye point kuonda zvinhu zvinosarudza zvinhu zvekuita muchinyorwa. Nekutsaura iyo yakatemwa chisel yemupendero unoderedzwa kusvika sezvinobvira. |
| Kuita chokwadi | Kutungamira chamfers uye sekondari yekucheka matura Kutungamira chamfers uye sekondari yekucheka mipendero inokanganisa kurongeka kwekutenderera kweiyo twist drill uye kunaka kwegomba rekuchera. |
| Kugadzikana | Musimboti Iyo core ickness ndiyo chiyero chekusimbisa kwekugadzikana kweiyo twist kudhiraivha. |
Chaizvoizvo, iwe unogona kuona yako application uye zvinyorwa zvaunoda kudhiraira mukati.
Tarisa uone kuti ndechipi chinodhirawa chinopihwa uye chienzanisa zvinhu zvine chekuita uye mabasa aunoda kuti zvinhu zvako zviite kuti zvidwe.
