Kwihlabathi lokusebenza ngentsimbi, ukuchaneka yinto yonke. Omnye wemibuzo eqhelekileyo evela kubasasazi kunye nabasebenzisi bokugqibela ngulo: "Yintoni i-RPM echanekileyo ye-drill bit yam?" Ukuseta isantya esifanelekileyo ngumahluko phakathi komngxuma ococekileyo kunye nesixhobo esonakeleyo. Ukuba isantya siphezulu kakhulu, ukungqubana kuvelisa ubushushu obugqithisileyo, okukhokelela kwincam "etshisiweyo". Ukuba iphantsi kakhulu, ukusebenza kakuhle kuyehla, kwaye usengozini yokuqhawula i-bit ngenxa ye-torque ephezulu.
Ukuqonda Iziseko: Ukusika Isantya vs. RPM
Ngaphambi kokubala isantya, kufuneka uqonde iSisantya sokusika i-Vc. Oku kumele isantya apho umphetho wokusika we-drill bit uhamba khona phezu komphezulu wesixhobo somsebenzi.
Nangona isantya sokusika simiselwa zizinto ezisetyenziswa kwindawo yokusebenza, i-RPM (iiRevolutions ngoMzuzu) yindlela oyilungisa ngayo kwi-drill press yakho okanye kumatshini we-CNC.
Ifomula yeMathematika yokuChaneka
Ukuze ufumane i-RPM echanekileyo efunekayo kumsebenzi wakho othile, iinjineli ezingoochwephesha zisebenzisa le fomyula ilandelayo:
Idatha yeReferensi yoMgangatho woShishino
Le datha ilandelayo isekelwe kwimigangatho yobunjineli eyaziwayo kwihlabathi liphela (efana ne-ISO 3685 kunye ne-DIN 1414) yezixhobo ze-High-Speed Steel (HSS). La maxabiso asebenza njengomlinganiselo wehlabathi jikelele wokhuseleko kunye nokusebenza kakuhle kokusebenza kwesinyithi.
Icebiso Elilungileyo: Xa usebenzisa ii-drill bits ze-HSS-Co (Cobalt), ngokubanzi ungazonyusa ezi santya nge-20% ngenxa yokumelana nobushushu okuphezulu kwezixhobo.
Izinto ezi-3 ezibalulekileyo ezichaphazela iziphumo zakho
Ngaphaya kwefomyula, izinto ezintathu zangaphandle ziya kumisela impumelelo yakho:
- Ulawulo lobushushu kunye nokuthambisa
Ubushushu lolona tshaba luphambili lwe-HSS. Ukusebenzisa ioyile yokusika esemgangathweni ophezulu okanye i-coolant kukuvumela ukuba usebenze kwisiphelo esiphezulu soluhlu lwe-RPM olucetyiswayo. Ngaphandle kokuthambisa, kufuneka uhlale kwisiphelo esisezantsi "esikhuselekileyo" sesikali ukuthintela intsimbi ukuba ithambe.
- Ukukhupha iiChip (Indlela "yokuPeck")
Kwimingxuma enzulu, i-RPM kufuneka ilinganiswe ngokususwa kweetships. Ukuba iitships (ii-metal curls) azikwazi ukuphuma kwiiflutes, ziya kuvala kwaye zitshise kakhulu i-bit. Sicebisa "ukubhoboza iipecks" - ukurhoxa i-bit rhoqo ukuze kususwe inkunkuma.
- Uzinzo loomatshini
Ukuba usebenzisa i-power drill ephathwa ngesandla, soloko usebenzisa i-RPM ephantsi kunexabiso elibaliweyo. Izixhobo eziphathwa ngesandla zinokungcangcazela okukhulu kwaye azinzi kangako kune-fixed drill press, nto leyo enyusa umngcipheko wokuba i-bit "ihambe" okanye iphuke.
Isiphelo
Ukusebenzisa i-RPM echanekileyo yeyona ndlela ilula yokwandisa ubomi beemveliso zakho zeJiacheng Tools. Ngokulandela le migangatho yamazwe ngamazwe, uqinisekisa ukuba ii-HSS drill bits zakho zihlala zibukhali, imingxunya yakho ihlala ichanekile, kwaye iindleko zakho zokuvelisa zihlala ziphantsi.
