Nyaya: Nei Zvidimbu zveDrill Zvichikundikana | Chinyorwa 15
Mazwi akakosha: kuchera simbi isingatsvi, nei simbi isingatsvi yakaoma kuboora, kusimbisa simbi isingatsvi, kuchera chidimbu chesimbi isingatsvi 304 316, M35 cobalt HSS drill bit, kupwanya chip yesimbi isingatsvi, simbi isingatsvi inopisa zvakanyanya, simbi isingatsvi yakavakwa mumucheto, 135 split point stainless steel, red hardness drill bit, work hardening drill failure, stainless steel drilling RPM feed
Bvunza chero ani zvake akamboboora 304 kana 316 stainless floor muchitoro kuti dambudziko nderei, uye uchawana izwi rimwe chete usati wawana sainzi: sticky. Chibooreso hachingorambi chete - zvinoita sekunge zvinoomera kusunda kana wava mugomba kwenguva yakareba. Tsananguro iyoyo yakarurama. Haina kukwanawo.
Simbi isina ngura haisi yakaoma kuiboora nekuti yakaoma. Kana yave yakabatidzwa, mhando dzakajairika dzakadai se304 ne316 dzinowanzova dzakapfava kupfuura simbi yesimbi yakaoma. Chinoita kuti simbi isina ngura ive yakasiyana ndechekuti kuiboora kunotanga maitiro mana akasiyana panguva imwe chete, uye imwe neimwe inoita kuti dzimwe nhatu dzive dzakaipa. Kunzwisisa kuti denderedzwa iri - kwete kungoziva kuti "stainless yakaoma" - ndiko kunoparadzanisa maitiro ekuboora anoshanda kubva kune anodya zvidimbu.
Haisi Dambudziko reKuoma
Kana kuomarara kwega ndiko kwakatsanangura dambudziko, chidimbu chakaoma chekuboorera chaizogadzirisa dambudziko racho. Muchokwadi, zvitoro zvakawanda zvinochinja kuita chidimbu chakaoma uye zvichiri kupisa kuburikidza nacho mumaburi akafanana. Izvi zvinodaro nekuti michina mina iri pazasi haishande imwe panguva imwe - inodyidzana muchidimbu, uye chidimbu ndicho chinoparadza chidimbu chekuboorera.
● Kushanda zvakanaka uye kusashanda zvakanaka kwezvimedu — chinhu chacho hachibvi zvakanaka
● Kupisa kushoma — kupisa kunogadzirwa hakuna kwekuenda
● Kuomesa basa — pamusoro pacho panonyanya kuoma panzvimbo chaiyo yauri kuedza kucheka
● Kupisa kwakanyanya pamucheto wepamusoro — chibooreso chinotora chirango chisingagone kunwiwa nechinhu chebasa
Imwe neimwe yeiyi inozivikanwa ne austenitic stainless stainless pachayo. Vatengi vanowana failure mode ndizvo zvinoitika kana ese ari mana achishanda panguva imwe chete.
Sei Zvisina Kunaka Zvichinzwika "Zvichinamira" - Kugadzikana uye Kusaputsika Kwemachipisi
304 na316 dzakapfava kupfuura simbi yekabhoni, zvinoreva kuti zvinhu zvinoshanduka uye zvinotambanuka pamberi pemucheto wekupedzisira pane kuchekwa kuita chip pfupi. Mugumisiro wacho i chip refu, rinoramba riripo, rinotenderera panzvimbo pezvidimbu zvidiki zvakaputsika zvaungawana musimbi isina kupfava.
Mareferensi ekugadzirwa kwesimbi isina ngura anotsanangura mamakisi e austenitic nemashoko aya chaiwo — seane "huwandu hwakawanda hwekushanda nesimba uye hunhu husina kunaka hwekupwanya machipisi" panguva yekugadzira.
Kwakabva: mabhuku ekuongorora mashandiro esimbi isingasvibi (nhungamiro yehunyanzvi muindasitiri yekugadzira).
Machipisi marefu anotenderera haangotaridzike seasina kurongeka chete. Anoputira muviri wechibooreso, oisa mufirita, uye kana zvisina kunaka anovhara chishandiso chose. Firita yakasungirirwa haigone kutakura machipisi - kana kupisa - kubva mugomba, izvo zvinosundidzira dambudziko zvakananga muchikamu chinotevera.
Kupisa Kusina Kwekuenda
Kupisa kwesimbi isina ngura kunosvika chikamu chimwe muzvitatu chesimbi yekabhoni — kazhinji iri pakati pe15–30 W/m·K zvichienzaniswa ne30–60 W/m·K yesimbi yakajairwa yekabhoni. Muchokwadi, izvi zvinoreva kuti kupisa kunobva pamucheto wekabhoni hakupararire muchinhu chakakomberedza sezvainoita musimbi isina ngura. Kunoramba kwakabatana chaizvo panzvimbo inonyanya kushandiswa nedhiri.
Kazhinji, chikamu chikuru chekucheka kupisa chinobuda nechip. Asi chip yatatsanangura — yakareba, ine tambo, yakaputirwa muflutes — haisi kubvisa gomba zvakanakawo. Kupisa kushoma kunobuda nechip, uye zvinosara zvinotorwa nemudziyo nepamusoro patsva. Ndiyo hukama hwakananga pakati pekubvisa chip zvisina kunaka nekupisa kwemucheto: haisi matambudziko maviri akasiyana, idambudziko rimwe chete rinozviwedzera.
Kuomesa Basa — Kana Gomba Richirwisa
Iyi ndiyo inowanzouraya chidhiraivho, uye imhaka yekupisa kwatsanangurwa pamusoro apa. Kana mucheto wekucheka uchikwesha panzvimbo pekucheka — kudya kushoma, kumhanya kwakanyanya, kana nguva yekuzeza pakati pegomba — kukweshana nekumanikidzwa kunoshanda jira rakatetepa repamusoro. Rutivi irworwo runosimba. Kana risina ngura, nzvimbo yakakanganiswa inogona kusvika pa40–50 HRC, yakaoma kupfuura iyo dhiraivho inowanzo gadzirwa kuti icheke.
Musungo: kana bhora raoma, bhora rinotonyanya kuoma parinozobuda, izvo zvinokonzera kukwesha zvakanyanya, izvo zvinoita kuti pamusoro paro pave pakaoma. Rinozvisimbisa — uye rinotanga kana bhora ramira kucheka zvakanaka.
Ndosaka mutemo wepasi pechitoro wekuti simbi isapinda tsvina wakanyatsojeka: usamborega kudya simbi ichitenderera. Kumbomira kwesekondi imwe chete kana mbiri, chidimbu chichiri kutenderera chakabatana nechinhu chacho, kazhinji zvakakwana kuti nzvimbo iyoyo iome kupfuura zvingaitwa nechibooreso chimwe chete mushure mezvo.
Maonero Anoita Zvinhu Zvina
Yakarongwa secheni, kurongeka kwekukundikana kunotaridzika seizvi:
Kwainopinda Drill Bit
Zvichitevera zvese zvataurwa pamusoro apa, zvinokwezva kutsvaga chinhu chakaomarara uye kufunga kuti dambudziko ragadziriswa. Ndiyo frame isiriyo. Chikonzero nei M35 cobalt HSS ichiita zvakanaka kupfuura M2 HSS yakajairwa mu stainless steel hachisi chekuti M35 inongooma - ndechekuti M35 inoramba yakasimba uye ine simba rekucheka patembiricha yakakwira. M2 HSS inotanga kurasikirwa nekuoma kwayo kwemucheto pa400°C; huwandu hwe cobalt muM35 hunosundira chiyero chekuoma kutsvuku kusvika pa600°C.
Sezvo dambudziko guru mukuboorera kusina ngura riri kupisa kusina kwekuenda, giredhi rekuboorera rinochengetedza mucheto waro wepamusoro pakupisa kwakanyanya riri kugadzirisa mashandiro chaiwo - kwete kungoramba kupera zvachose. Kurongeka kwacho kwakakodzera kutaurwa zvakajeka:
Stainless inogadzira kupisa kwakasimba → tembiricha yepamusoro inokwira → HSS yakajairwa inorasikirwa nekuomarara uye inodzima nekukurumidza → kukwesha kusingafadzi pachinzvimbo chekucheka → kukwesha kunofambisa kuomarara kwebasa → kupisa kwakawanda → kukundikana. M35 cobalt inomisa denderedzwa iri padanho rekuti "kumucheto kunorasikirwa nekuomarara" - kwete padanho rekushanda, uye kwete padanho reRPM/feed.
Mapoinzi ejometri akakosha nekuda kwechikonzero chimwe chete, kubva pakona yakasiyana. Nzvimbo yakakamurwa ne135° (yakafukidzwa muchikamu cheGeometry chino) inoderedza kusvetukira nekufamba pakutanga kwegomba, izvo zvinopfupikisa hwindo apo chikamu chiri kukwesha pane kucheka zvakachena. Kusvetukira kushoma pakupinda zvinoreva mikana mishoma yekuomesa basa gomba risati ratanga.
Hapana chimwe cheizvi chinotsiva maitiro akarurama. M35 cobalt bit yakarongwa zvakanaka inomhanya paRPM isiriyo, isina kumanikidzwa kwekudya, kana ine mid-hole, icharamba ichishanda-ichiomesa zvinhu uye yokundikana - kunonoka zvishoma pane zvaingaitwa neHSS bit yakajairwa. Bhodhi rekuboorera rinosimudza denga; harigadzirise maparamita asina kunaka pasi paro.
Izvi Zvinorevei Kana Uchitsvaga Zvidimbu zveDrill zveStainless Work
Kana kuchera simbi isingasvibi kuri chinhu chinogara chichiitwa pakugadzira chigadzirwa chako kana kuti chiri kushandiswa nevatengi vako, mibvunzo mishoma inokosha kubvunzwa usati watenga:
● Ko mhando ye cobalt M35 kana M42 ndiyo chaiyo here — inosimbiswa nehuwandu hwe cobalt, kwete chete "yesimbi isingasvibi" iri papakeji?
● Ko geometry yemapoinzi inosanganisira poindi yakapatsanurwa ye135° here, kana poindi yakajairwa ye118° yakarongedzerwa simbi isina kusimba?
● Ko RPM/feed values dzinokurudzirwa dze stainless steel dzinotaurwa kune mushandisi wekupedzisira here, kana kuti dzinosiyiwa kuti vafungidzire?
● Ko mafuta anotonhodza kana ekucheka akavakirwa mumaitiro anokurudzirwa here, kana kuti anofungidzirwa chinyararire?
Hapana kana imwe yemibvunzo iyi ine mhinduro chaiyo — inoenderana nerudzi rwesimbi isina ngura, kudzika kwegomba, uye michina. Asi mutengesi anogona kuverenga nezvayo newe kazhinji anonzwisisa nzira yekukundikana kupfuura uyo anongopa zita rechigadzirwa rinonzwika serakaoma.
Nezvenyaya iyi
Chikonzero nei Drill Bits Isingashande inyaya yehunyanzvi yakanyorwa nechikwata chedu chekugadzira. Chinyorwa chimwe nechimwe chinotarisa pane chimwe chinhu chaicho mukushanda kwedrill bit - kubva pazvinhu zvisina kugadzirwa kusvika pakurongedza. Chinangwa chiri nyore: kubatsira vatengi kunzwisisa zvavari kutenga chaizvo, uye mibvunzo yekubvunza.
