Unoziva mazwi aya here: Helix angle, point angle, main cutting edge, profile of flute? Kana zvisina kudaro, unofanira kuramba uchiverenga. Tichapindura mibvunzo yakaita seyi: Chii chinonzi secondary cutting edge? Chii chinonzi helix angle? Anokanganisa sei kushandiswa muapplication?
Nei zvichikosha kuziva zvinhu izvi: Zvinhu zvakasiyana-siyana zvinoda chishandiso zvakasiyana. Nekuda kweizvi, kusarudzwa kwechibhorani chinotenderedzwa chine chimiro chakakodzera kwakakosha zvikuru pamhedzisiro yekuboorwa.
Ngatitarisei zvinhu zvisere zvinokosha zve drill yekumonera: point angle, main cutting edge, cut chisel edge, point cut and point thinning, profile of flute, core, secondary cutting edge, uye helix angle.
Kuti zviite basa rakanaka rekucheka zvinhu zvakasiyana-siyana, zvese zvisere zvinofanira kuenzaniswa.
Kuti tienzanise izvi, tinoenzanisa madhiri matatu anotevera ekugadzirisa bhora:
- Chibooreso che twist DIN 338, HSS-E
- Zvidhiraivho zveTwist DIN 338, HSSE-Co M35
- Kuboorera kwakamonyoroka DIN 338, HSS 4341
Kona yepfungwa
Kona yekona iri pamusoro pechibhora chinotenderedzwa. Kona yacho inoyerwa pakati pemipendero miviri mikuru yekucheka iri pamusoro. Kona yekona inodiwa kuti chibhora chinotenderedzwa chive pakati pechinhu chacho.
Kana kona yekona iri diki, zviri nyore kuisa pakati pechinhu chacho. Izvi zvinoderedzawo njodzi yekutsvedza panzvimbo dzakakombama.
Kana kona yekona yakakura, nguva yekubaya ipfupi. Zvisinei, kumanikidzwa kwakanyanya kunodiwa uye kuisa pakati pechinhu kwakaoma.
Zvakagadziriswa nejometri, kona diki yenzvimbo inoreva mipendero mirefu yekucheka, nepo kona hombe yenzvimbo inoreva mipendero mipfupi yekucheka.
Micheto mikuru yekucheka
Micheto mikuru yekucheka inotora basa rekugadzira bhora chairo. Micheto mirefu yekucheka ine simba rekucheka rakakwirira zvichienzaniswa nemicheto mipfupi yekucheka, kunyangwe musiyano wacho uri mudiki.
Chibhorani chinotenderedza madziro chine mipendero miviri mikuru yekucheka yakabatana nemupendero wechisel wakachekwa.
Cheka mucheto wechisel
Mupendero wechisel wakachekwa uri pakati pemuromo wechibooreso uye hauna simba rekucheka. Zvisinei, zvakakosha pakuvaka chibooreso chakatenderedzwa, sezvo chinobatanidza mipendero miviri mikuru yekucheka.
Mupendero wechisel wakachekwa ndiwo unokonzera kupinda kwechinhu uye unomanikidza uye unokwesha chinhu chacho. Hunhu uhwu, husina kunaka pakuboorwa, hunokonzera kuwedzera kwekupisa uye kushandiswa kwesimba.
Zvisinei, zvinhu izvi zvinogona kuderedzwa nezvinonzi "kuonda".
Kucheka kwepoinzi uye kutetepa kwepoinzi
Kutetepa kwepoindi kunoderedza mupendero wechisel wakachekwa pamusoro pechibhorani chinotenderedza. Kutetepa uku kunoguma nekuderera kukuru kwemasimba ekukweshana ari muchigadzirwa uye nokudaro kuderera kwesimba rekudya rinodiwa.
Izvi zvinoreva kuti kutetepa ndicho chinhu chinonyanya kukosha pakuisa pakati pechinhu. Zvinovandudza kugocha.
Kupatsanurwa kwemapoinzi akasiyana-siyana kwakaenzana muchimiro cheDIN 1412. Maumbirwo akajairika ipoinzi yemupendero (chimiro N) uye poindi yakapatsanurwa (chimiro C).
Mbiri yeflute (mbiri yegroove)
Nekuda kwebasa rayo senzira yekufambisa flute, chimiro cheflute chinokurudzira kunyudzwa kwetsvina uye kubviswa kwayo.
Kana groove yacho yakakura, zvinoita kuti chips ikwanise kunyudzwa uye kubviswa zvakanaka.
Kubvisa machipisi zvisina kunaka zvinoreva kuti kupisa kwakanyanya, izvo zvinogona kukonzera kupwanyika kwesimbi uye pakupedzisira kutyoka kwechibhorani chetwist.
Mapurofayiro akafara akati sandara, mapurofayiro akatetepa akadzama. Kudzika kwepurofayiro yepurofayi ndiko kunosarudza ukobvu hwepakati pechibooreso. Mapurofayiro akatetepa epurofayiro anobvumira dhayamita hombe (dzakakora). Mapurofayiro akadzama epurofayiro anobvumira dhayamita diki (dzakatetepa) dzepakati.
Core
Ukobvu hwepakati ndicho chinoyera kugadzikana kwechibhorani chinotenderedza.
Mabhora ekumonera ane dhayamita hombe (core dayamita) ane kugadzikana kwakanyanya uye nekudaro akakodzera ma torque akakwira uye zvinhu zvakaoma. Akakodzerawo kushandiswa mumabhora emaoko sezvo anodzivirira kuzununguka uye simba remativi.
Kuti zvive nyore kubvisa machipisi kubva mumugero, ukobvu hwepakati hunowedzera kubva pamucheto wekuboorera kusvika pahunde.
Machamfer anotungamira uye mipendero yekucheka yechipiri
Machamfer maviri ekutungamira ari pamigero. Machamfer akakweshwa anoshandawo pamativi egomba uye anotsigira kutungamira kwechibhorani chakatenderedzwa mugomba rakaboorwa. Hunhu hwemadziro egomba hunoenderanawo nehunhu hwechamfers dzekutungamira.
Mupendero wechipiri unogadzira shanduko kubva pakuva machamfer anotungamira kuenda kuchimiro chemugero. Unosunungura nekucheka machipisi akanamira pachinhu chacho.
Kureba kwemachamfer ekutungamira uye mipendero yekucheka yechipiri zvinoenderana zvakanyanya nekona yehelix.
Kona yeHelix (kona inotenderera)
Chinhu chakakosha che twist drill i helix angle (spiral angle). Ndiyo inosarudza maitiro ekuumbwa kwechip.
Makona makuru e helix anobvisa zvinobudirira zvinhu zvakapfava uye zvinocheka-cheka kwenguva refu. Makona madiki e helix, kune rumwe rutivi, anoshandiswa pazvinhu zvakaoma uye zvinocheka-cheka kwenguva pfupi.
Madrill ekutenderedza ane kona diki kwazvo yehelix (10° – 19°) ane spiral refu. Mukudzosera, twist drill ine kona hombe yehelix (27° – 45°) ine spiral yakakombama (pfupi). Madrill ekutenderedza ane spiral yakajairika ane helix angle ye19° – 40°.
Mabasa ehunhu mukushandiswa
Pakutanga, nyaya yetwist drills inoita kunge yakaoma. Ehe, kune zvakawanda zvinhu zvinosiyanisa twist drill. Zvisinei, hunhu hwakawanda hunoenderana.
Kuti uwane nzira chaiyo yekuboorera, unogona kuzvitungamira kune yako application muchikamu chekutanga. Bhuku reDIN remaboorera nema countersinks rinotsanangura, pasi peDIN 1836, kupatsanurwa kwemapoka eapplication kuita mhando nhatu N, H, uye W:
Mazuva ano hauzongowani mhando nhatu idzi N, H, naW chete dziri pamusika, nekuti nekufamba kwenguva, mhando idzi dzakarongwa zvakasiyana kuti dzigadzirise madhiri etwist kune mamwe mashandisirwo akakosha. Saka, mafomu ehybrid akaumbwa ane masisitimu ekutumidza mazita asina kurongeka mubhuku reDIN. PaMSK hauzowani mhando N chete asiwo mhando dzeUNI, UTL kana VA.
Mhedziso uye pfupiso
Iye zvino wava kuziva kuti ndeapi maficha echibhorani chinotenderedza maitiro ekuboorera. Tafura inotevera inokupa ruzivo rwezvinhu zvakakosha zvemabasa acho.
| Basa | Zvinhu zvirimo |
|---|---|
| Kucheka mashandiro | Micheto mikuru yekucheka Micheto mikuru yekucheka inotora maitiro chaiwo ekuboorera. |
| Hupenyu hwebasa | Mbiri yeflute (mbiri yegroove) Hunhu hwenyere inoshandiswa senzira yekufambisa nyere hune basa rekubvisa machipisi uye kuanyudza, saka, chinhu chakakosha pahupenyu hwebasa remuchina wekupinza nyere. |
| Kushandiswa | Kona yekona & kona yeHelix (kona yekona inotenderera) Kona yekona nekona yehelix ndizvo zvinhu zvakakosha pakushandisa zvinhu zvakaoma kana zvakapfava. |
| Kuisa pakati | Kucheka kwepoinzi uye kutetepa kwepoinzi Kucheka kwepoinzi uye kutetepa kwepoinzi ndizvo zvinhu zvikuru zvinoita kuti pave nepakati pechinhu chacho. Nekuchekerera chisel, mupendero wayo unodzikira zvakanyanya sezvinobvira. |
| Kururama kweConcentricity | Machamfer anotungamira uye mipendero yekucheka yechipiri Machamfer anotungamira uye mipendero yekucheka yechipiri inokanganisa kururama kwechero rinotenderedzwa uye kunaka kwegomba rekuboorera. |
| Kugadzikana | Core Ukobvu hwepakati ndicho chiyero chakakosha chekugadzikana kwechibooreso chinotenderedza. |
Chaizvoizvo, unogona kusarudza mashandisirwo aunoita uye zvinhu zvaunoda kudzidzira.
Tarisa kuti ndeapi madhiri ekukwesha anowanikwa uye enzanisa maficha nemabasa aunoda kuti chinhu chako chiboorwe.
