Sanibonani nonke!
Uma uvame ukwenza amaphrojekthi okulungisa imigodi, uvame ukuba nemibuzo efana nalokhu: Kungani i-drill bit yami engu-10mm ikhiqiza imbobo engu-10.1mm? noma Kungani i-drill bit yami iphuka kalula kangaka?
Ezimweni eziningi, inkinga akuyona ukuqina kwe-drill bit okwanele, kodwa ukugeleza kwe-radial okungabonakali.
Kulesi sihloko, sizochaza ukuthi yini i-runout nokuthi kungani ibalulekile ngamazwi alula.
Kuyini i-runout?
Ngamafuphi, i-runout ibhekisela ekuxegaxekeni noma ekunyakazeni kwe-drill bit ngesikhathi sokujikeleza.
Cabanga ngokujikeleza okuphelele. Lapho i-drill bit ijikeleza ngaphakathi komshini, umugqa wayo ophakathi kufanele uvumelane kahle nomugqa ophakathi we-spindle yomshini. Kuleli qophelo, i-drill bit ibonakala ingashintshi ngokuphelele futhi izinzile kakhulu.
Kodwa-ke, uma i-drill bit ingaqondile kahle noma i-machine chuck ingakagxili kahle, i-drill tip izolandela indlela eyindilinga njengoba ijikeleza. Ubukhulu balokhu kuhamba okuxegayo bubizwa ngokuthi i-runout.
Yiziphi izinkinga zokuphelelwa yisikhathi?
Kuma-drill e-twist ensimbi esheshayo (i-HSS), ukungasebenzi kahle okukhulu kubi kakhulu. Kubangela izinkinga eziningi:
1. Imigodi emikhulu kakhulu (imigodi emikhulu): Lena yinkinga evame kakhulu. Ngenxa yokuthi i-drill iyaxega, empeleni isika indawo enkulu kunobubanzi bayo.
2. Izindonga ezinemigodi eqinile: I-drill enyakazayo ikhuhla izindonga zangaphakathi zembobo, okubangela indawo elukhuni. Imbobo ingase ilahlekelwe ngisho nokuba yindilinga kwayo bese iba yi-elliptical.
3. Ukuncipha kwesikhathi sokubhoboza: Ukusatshalaliswa kwamandla okungalingani kuzo zombili izinqe zokusika ngenxa yokuzamazama kubangela ukuthi unqenqema olulodwa lusebenze kakhulu, okuholela ekugugeni nasekubuthakatheni okusheshayo.
4. Ingozi eyengeziwe yokuphuka kwebholi: Ukugeleza kwe-radial kudala ukudlidliza okukhulu. Lapho kubholwa imigodi ejulile, lokhu kudlidliza kuphula kalula ibholi.
Kungani kwenzeka ukugeleza kwegazi?
Ukungasebenzi kahle kwe-drill bit akuyona njalo iphutha. Ngokuvamile kuba “yinkinga yesistimu”:
• Izinkinga zamathuluzi omshini noma ze-chuck: Ingabe i-drill chuck yakho ingcolile ngama-chips ensimbi? Ingabe i-chuck igugile kakhulu? Lena inkinga evame kakhulu. Ukubopha okungalungile kuzokwenza i-drill bit inyakaze.
• Izinkinga zokufaka: I-drill bit ivele kakhulu noma ayiboshiwe kahle.
• I-drill bit ngokwayo: Yiqiniso, ezinye izingcezu zekhwalithi ephansi zingase zigobe ngokwemvelo noma zibe nemiphetho yokusika engalingani. ikakhulukazi, ama-twist drill enziwa kusetshenziswa izinqubo ezimbili: ukugoqa nokugaya. Ama-ground drill ngokuvamile anokugijima okungcono kune-rolled drills.
Unganquma kanjani?
Kunezindlela ezimbili eziyinhloko zokunquma ukugeleza kwebhodlela: ukuhlola okulula okubonakalayo kanye nokulinganisa okunembile. Ukuhlola okubonakalayo okuyisisekelo ukufaka i-drill bit bese uyijikeleza ngesivinini esiphansi bese ubheka i-drill bit ngezinga lamehlo akho. Uma i-drill top ibonakala icacile futhi izinzile, kuvamile; uma kwenzeka ukubona kabili, ukufiphala, noma ukwanda okubonakalayo "kwendilinga ejikelezayo", kubonisa ukugeleza okukhulu.
Indlela enembile kakhulu ihilela ukusebenzisa inkomba yokudayela (noma i-micrometer): qala ubambe i-drill bit ngokuphephile, bese ubeka i-indicator probe ngokumelene nomphetho osikiwe noma indawo ebushelelezi ye-shank. Jikelezisa i-spindle ngesandla indilinga eyodwa egcwele bese uqopha umehluko phakathi kwamanani aphezulu naphansi aboniswe yi-pointer. Lo mehluko umele i-total indicator runout (TIR).
Isiphakamiso sethu
Lapho sikhiqiza ama-drill ensimbi asheshayo, sinezindinganiso eziqinile zokuhlola ukuthi umzimba we-drill uqondile kangakanani kanye nokulingana kwemiphetho yokusika, okuqinisekisa ukuthi yonke i-drill bit ihlangabezana nezindinganiso zokunemba ngaphambi kokushiya ifektri yethu.
Futhi, ihhashi elihle lifanelwe isihlalo esihle. Ukuze uthole imiphumela emihle yokubhoboza, sicela ukhumbule ukuhlanza njalo nokuhlola i-chuck yamathuluzi omshini wakho!
Uma unemibuzo ngesikhathi sokulungisa, zizwe ukhululekile ukuxhumana nathi nganoma yisiphi isikhathi.
