Ezweni lokusebenza ngensimbi, ukunemba kuyikho konke. Omunye wemibuzo evame kakhulu evela kubasabalalisi kanye nabasebenzisi bokugcina uthi: "Iyini i-RPM efanele ye-drill bit yami?" Ukubeka isivinini esifanele umehluko phakathi komgodi ohlanzekile nethuluzi elonakele. Uma isivinini siphezulu kakhulu, ukungqubuzana kudala ukushisa okweqile, okuholela ekutheni "kushiswe". Uma siphansi kakhulu, ukusebenza kahle kuyehla, futhi usengozini yokunqamuka kwe-bit ngenxa ye-torque eyeqile.
Ukuqonda Okuyisisekelo: Isivinini Sokusika vs. I-RPM
Ngaphambi kokubala ijubane, kufanele uqonde i-Cutting Speed Vc. Lokhu kumelela ijubane lapho unqenqema lokusika lwe-drill bit luhamba khona phezu kobuso be-workpiece.
Nakuba ijubane lokusika linqunywa yizinto ezisetshenziswayo, i-RPM (Revolutions Per Minute) iyisethingi oyilungisayo ngempela kumshini wakho wokubhoboza noma umshini we-CNC.
Ifomula Yezibalo Yokunemba
Ukuze uthole i-RPM eqondile edingekayo emsebenzini wakho othize, onjiniyela abangochwepheshe basebenzisa ifomula ejwayelekile elandelayo:
Idatha Yezinkomba Ezijwayelekile Zemboni
Idatha elandelayo isekelwe ezindinganisweni zobunjiniyela eziqashelwa emhlabeni wonke (njenge-ISO 3685 kanye ne-DIN 1414) zamathuluzi e-High-Speed Steel (HSS). Lawa manani asebenza njengesilinganiso somhlaba wonke sokuphepha nokusebenza kahle kokusebenza kwensimbi.
Icebiso Elihle: Uma usebenzisa ama-drill bits e-HSS-Co (Cobalt), ngokuvamile ungawandisa lawa majubane ngo-20% ngenxa yokumelana nokushisa okuphezulu kwale nto.
Izinto Ezi-3 Ezibalulekile Ezithonya Imiphumela Yakho
Ngale kwefomula, izici ezintathu zangaphandle zizonquma impumelelo yakho:
- Ukuphathwa Kokushisa Nokugcoba
Ukushisa kuyisitha esiyinhloko se-HSS. Ukusebenzisa uwoyela wokusika osezingeni eliphezulu noma i-coolant kukuvumela ukuthi usebenze ekugcineni okuphezulu kobubanzi be-RPM obunconywayo. Ngaphandle kokuthambisa, kufanele uhlale ekugcineni "okuphephile" okuphansi kwesikali ukuvimbela insimbi ukuthi ithambe.
- Ukususwa Kwezicucu (Indlela "Yokugoba")
Uma kunemigodi ejulile, i-RPM kumele ilinganiswe nokususwa kwe-chip. Uma ama-chip (ama-curls ensimbi) engakwazi ukuphuma kuma-flute, azovala futhi ashise kakhulu i-bit. Sincoma "ukubhoboza i-peck" - ukuhoxisa i-bit ngezikhathi ezithile ukuze kusulwe imfucuza.
- Ukuqina Komshini
Uma usebenzisa i-power drill ephethwe ngesandla, sebenzisa njalo i-RPM ephansi kunenani elibalwe. Amathuluzi aphethwe ngesandla anokudlidliza okukhulu kanye nokuqina okuncane kunomshini wokubhoboza ohleliwe, okwandisa ingozi yokuthi ingxenye "ihambe" noma iphuke.
Isiphetho
Ukusebenzisa i-RPM efanele kuyindlela elula yokwandisa impilo yemikhiqizo yakho ye-Jiacheng Tools. Ngokulandela lezi zindinganiso zomhlaba wonke, uqinisekisa ukuthi izingcezu zakho zokubhoboza ze-HSS zihlala zibukhali, imigodi yakho ihlala iqondile, futhi izindleko zakho zokukhiqiza zihlala ziphansi.
