Emkhakheni wokucubungula insimbi yesimanje, ukunemba nokusebenza kahle kwenqubo yokubhoboza kunquma ngqo ikhwalithi kanye nezindleko zokukhiqiza umkhiqizo. Ukuphendula lesi sidingo esiyinhloko, i-HRC 4241 HSSi-drill eqondile yokujika kwe-shanksekuyisinqumo esidumile ekukhiqizeni kwezimboni, ekucubungulweni kwemishini ngisho nasemakethe ye-DIY ngomklamo wayo omusha kanye nokuthembeka okuphezulu. Lesi sihloko sizohlaziya ngokujulile izici zobuchwepheshe kanye nezimo zokusetshenziswa kwaleli thuluzi, siveze ukuthi linikeza kanjani izixazululo eziguquguqukayo nezisebenzayo kubasebenzisi emazingeni ahlukene.
1. Umklamo wesakhiwo omusha: umqondo wokuziphendukela kwemvelo wemifula ejikelezayo
Njengo-"umphefumulo" we-twist drill, uhlelo lwe-spiral groove lwe-HRC 4241 lusebenzisa umqondo womklamo we-modular we-groove engu-2-3. Phakathi kwazo, inguqulo ye-double-groove ifinyelela ibhalansi ephelele phakathi kokusebenza kahle kokususa ama-chip kanye namandla esakhiwo "ngesilinganiso segolide" - i-engeli ye-helix ilungiswa yi-fluid mechanics ukuqinisekisa ukuthi ama-iron chips akhishwa ngokushesha ngesimo seribhoni eqhubekayo, ngenkathi kugcinwa ukuqina komzimba we-drill ukuze kugwenywe ukuphambuka kokudlidliza. Uhlobo lwe-three-groove lugxile ezimweni ezinembe kakhulu. Ngokwandisa isiteshi sokususa ama-chip, kunciphisa kakhulu ukuqongelela kokushisa lapho kukhishwa imigodi ejulile. Ifaneleka kakhulu ekusebenzeni okuqhubekayo kwezinto ezinamathelayo njengensimbi engagqwali kanye ne-titanium alloy.
2. Isiqongo sobuchwepheshe bezinto ezibonakalayo
Lolu chungechunge lwemikhiqizo lusebenzisa isu lezinto ezilandelanayo ezimbili ze-HSS (insimbi yamathuluzi eshesha kakhulu) kanye ne-carbide. Izinto eziyisisekelo ze-HSS zizinzile ebangeni le-HRC63-65 ngenqubo yokwelapha ukushisa yezinga elingu-4241. Ngobuchwepheshe obukhethekile bokumboza, umkhawulo wokumelana nokushisa udlula u-600°C, futhi unqenqema lungaba lubukhali ngesikhathi sokucubungula okuqhubekayo. Inguqulo ye-carbide ethuthukisiwe isebenzisa ubuchwepheshe bokushiswa kwezinhlamvu ezincane, futhi ukumelana kwayo nokuguguleka kungaphezu kokuphindwe kathathu kunokwemishini yokuzivocavoca yendabuko. Ifaneleka kakhulu ezintweni okunzima ukuzicubungula njengensimbi eqinile nezinto ezihlanganisiwe, okunikeza isivikelo sesikhathi eside sokukhiqiza ngobuningi.
3. Izici ze-Universal ziyahambisana nazo zonke izimo
I-matrix yomkhiqizo ephelele enobubanzi obungu-1mm-20mm, kanye nomklamo we-ISO standard straight shank, kwenza i-HRC 4241 ikwazi ukuzivumelanisa kalula nemishini ehlukahlukene kusukela kuma-drill kagesi aphathwayo kuya ezikhungweni zomshini ezine-axis ezinhlanu. Eshabhu lokulungisa okuzenzakalelayo, abasebenzi bangayilayisha ngqo ku-drill ejwayelekile yebhentshi ukuze bacubungule imigodi yediski yamabhuleki; uma ingena ensimini yokukhiqiza ephezulu, ingabambisana ngokuphelele ne-ER spring chuck yethuluzi lomshini we-CNC ukuze yenze ukubhola kokubeka ngokunemba okungu-±0.02mm. Lokhu kuhambisana kwezinga eliphakathi kwenza kube yisisombululo sokushintsha okubushelelezi sokuthuthukiswa kwemishini yebhizinisi.
Umbono Wemakethe:
Ngokuthuthukiswa okuhlakaniphile kwemboni yokukhiqiza yomhlaba wonke, uchungechunge lwe-HRC 4241 olunezindleko eziphezulu zokusebenza kanye nokuguquguquka kwenqubo lungena ngokushesha emakethe yamathuluzi e-carbide yendabuko. Idatha yenkampani yangaphandle ikhombisa ukuthi isabelo semakethe salo mkhiqizo ensimini yesikhunta sezimoto zasekhaya sifinyelele ku-19%, futhi sigcina isilinganiso sokukhula kwe-compound yonyaka esingu-7%. Esikhathini esizayo, ngokwethulwa kobuchwepheshe obusha njenge-nano-coating, le "evergreen" yezimboni izoqhubeka nokubhala isahluko esisha ekucutshungulweni okuphumelelayo.
Kungakhathaliseki ukuthi ukulawulwa kwezindleko okulandelwa ama-workshop amancane okusebenza ngomshini noma ukuzinza kwenqubo okuthinteka yizinkampani ezinkulu zokukhiqiza, i-HRC 4241 HSSi-drill bit eqondile ye-shankibonise ukuzivumelanisa nezimo okunamandla kwendawo. Ngokusebenzisa izindlela ezimbili ezintsha zokwakha kanye nokwenza ngcono isakhiwo, ichaza kabusha amazinga okusebenza kahle kwemisebenzi yokubhoboza yesimanje futhi inikeze ukwesekwa kobuchwepheshe okuyisisekelo kokuguqulwa nokuthuthukiswa kwemboni yokukhiqiza.
