Mu isi y’ubukorikori bw’ibyuma, gukora neza ni byo byose. Kimwe mu bibazo bikunze kubazwa n’abakwirakwiza ibikoresho n’abakoresha ni iki: "Ni iyihe RPM ikwiye kuri drill bit yanjye?" Gushyiraho umuvuduko ukwiye ni itandukaniro riri hagati y’umwobo usukuye n’igikoresho cyangiritse. Iyo umuvuduko uri hejuru cyane, gukururana bitera ubushyuhe bwinshi, bigatuma umutwe "utwikwa". Iyo uri hasi cyane, ubushobozi buragabanuka, kandi ushobora gucikamo bit bitewe n’imbaraga nyinshi.
Gusobanukirwa iby'ibanze: Kugabanya umuvuduko ugereranije na RPM
Mbere yo kubara umuvuduko, ugomba gusobanukirwa umuvuduko wo gukata Vc. Ibi bigaragaza umuvuduko aho inkombe y'icyuma cyo gucukura inyura hejuru y'icyuma gikorerwaho.
Nubwo umuvuduko wo gukata ugenwa n'ibikoresho by'igikoresho, RPM (Revolutions Per Minute) ni imiterere uhindura ku mashini yawe yo gucukura cyangwa CNC.
Uburyo bwo gukoresha imibare mu gutunganya neza
Kugira ngo ubone RPM nyayo ikenewe ku murimo wawe wihariye, injeniyeri z'inzobere zikoresha formula isanzwe ikurikira:
Amakuru Asanzwe ku Nganda
Amakuru akurikira ashingiye ku mahame y’ubuhanga yemewe ku rwego mpuzamahanga (nka ISO 3685 na DIN 1414) ku bikoresho by’icyuma cyihuta cyane (HSS). Aya mahame ni yo akoreshwa ku rwego mpuzamahanga mu kurinda umutekano no kunoza imikorere y’icyuma.
Inama y'ingirakamaro: Mu gihe ukoresha utubuto twa HSS-Co (Cobalt), muri rusange ushobora kongera uyu muvuduko ho 20% bitewe n'uko ubushyuhe bw'ibikoresho budashobora kwiyongera.
Ibintu 3 by'ingenzi bigira ingaruka ku musaruro wawe
Uretse formula, ibintu bitatu byo hanze bizagena intsinzi yawe:
- Gucunga ubushyuhe no gusiga amavuta
Ubushyuhe ni umwanzi w’ibanze wa HSS. Gukoresha amavuta yo gukata cyangwa icyuma gikonjesha cyiza bigufasha gukora ku mpera yo hejuru y’urugero rwa RPM rwasabwe. Udafite amavuta yo kwisiga, ugomba kuguma ku mpera yo hasi "y’umutekano" y’urupi kugira ngo wirinde ko icyuma cyoroha.
- Gukuraho Chips (Uburyo bwa "Peck")
Ku myobo miremire, RPM igomba kuringanizwa no gukuraho uduce duto. Niba uduce duto (imigozi y'icyuma) tudashobora kuva mu miyoboro, turaziba kandi tugashyushya cyane igice. Turakugira inama yo "gucukura uduce duto"—gukuramo igice buri gihe kugira ngo ukureho imyanda.
- Gukomera kw'imashini
Niba ukoresha drill ikoresha intoki, buri gihe koresha RPM iri hasi ugereranije n'agaciro kabazwe. Ibikoresho bikoresha intoki bifite vibration nyinshi kandi ntibigire umuvuduko ukabije ugereranije n'imashini ikoresha drill, ibyo byongera ibyago byo "gugenda" cyangwa kuvunika.
Umwanzuro
Gukoresha RPM ikwiye ni bwo buryo bworoshye bwo kongera igihe cy'ibicuruzwa byawe bya Jiacheng Tools. Ukurikije aya mahame mpuzamahanga, uba wizeye ko uduce twa HSS drill dukomeza kuba duto, imyobo yawe igakomeza kuba ndende, kandi ikiguzi cyo kuyikora kigakomeza kuba gito.
