Munyika yekushanda nesimbi, kunyatsoita zvinhu nemazvo ndicho chinhu chikuru. Imwe yemibvunzo inowanzo bvunzwa nevanotengesa zvinhu nevashandisi ndeyekuti: "Ndeipi RPM chaiyo ye drill bit yangu?" Kuisa kumhanya kwakakodzera ndiko musiyano uripo pakati pegomba rakachena nechishandiso chakaora. Kana kumhanya kwacho kwakanyanya, kukweshana kunounza kupisa kwakanyanya, zvichikonzera kuti "tip" itsve. Kana kwakaderera, kushanda zvakanaka kunodzikira, uye unogona kutyora bit nekuda kwe torque yakawandisa.
Kunzwisisa Zvinonyanya Kukosha: Kucheka Kumhanya vs. RPM
Usati waverenga kumhanya, unofanira kunzwisisa Cutting Speed Vc. Izvi zvinomiririra kumhanya uko kumucheto kwe drill bit kunofamba pamusoro pe workpiece.
Kunyange hazvo Kumhanya Kwekucheka kuchitsanangurwa nezvinhu zviri pachinhu chacho, RPM (Revolutions Per Minute) ndiyo gadziriro yaunogadzirisa padhiri rako redhiri kana muchina weCNC.
Fomura yemasvomhu yeKunyatsorurama
Kuti uwane RPM chaiyo inodiwa pabasa rako, mainjiniya vane hunyanzvi vanoshandisa fomura inotevera:
Ruzivo rweMaitiro Eindasitiri
Ruzivo runotevera rwakavakirwa pamitemo yeinjiniya inozivikanwa pasi rose (yakadai seISO 3685 neDIN 1414) yekushandisa High-Speed Steel (HSS). Aya maturusi anoshanda sechiyereso chepasi rose chekuchengetedza uye kushanda zvakanaka kwebasa resimbi.
Zano Repamusoro: Paunenge uchishandisa mabhora eHSS-Co (Cobalt), unogona kuwedzera kumhanya uku ne20% nekuda kwekudzivirira kupisa kwakanyanya kwechigadzirwa.
Zvinhu Zvitatu Zvakakosha Zvinokanganisa Zvaunowana
Kupfuura fomura, zvinhu zvitatu zvekunze ndizvo zvichasarudza kubudirira kwako:
- Kutarisira Kupisa uye Kuzora Mafuta
Kupisa ndiko muvengi mukuru weHSS. Kushandisa oiri yekucheka yepamusoro kana chinhu chinotonhodza kunoita kuti ushande pamucheto wepamusoro weRPM inokurudzirwa. Pasina mafuta ekuzora, unofanirwa kugara pamucheto wepasi "wakachengeteka" wechikero kudzivirira simbi kuti isapfave.
- Kubvisa Chips (Nzira ye "Peck")
Kune maburi akadzika, RPM inofanira kuenzaniswa nekubvisa machipisi. Kana machipisi (simbi dzakakombama) asingakwanise kubuda mumafirita, anovhara uye anopisa zvakanyanya. Tinokurudzira "kuboorera peck" - kudzosera chidimbu nguva nenguva kuti ubvise marara.
- Kugadzikana kwemuchina
Kana uchishandisa chidhiraivha chemagetsi chinobatwa nemaoko, gara uchishandisa RPM yakaderera pane kukosha kwakaverengerwa. Zvishandiso zvinobatwa nemaoko zvine vibration yakawanda uye kusagadzikana kushoma pane chidhiraivha chakagadzika, izvo zvinowedzera njodzi yekuti chidimbu "chifambe" kana kutyoka.
Mhedziso
Kushandisa RPM chaiyo ndiyo nzira iri nyore yekuwedzera hupenyu hwezvigadzirwa zvako zveJiacheng Tools. Nekutevera mitemo iyi yepasi rose, unoita shuwa kuti maburi ako eHSS drill anoramba akapinza, maburi ako anoramba akakwana, uye mari yekugadzira inoramba yakaderera.
