Molweni nonke!
Ukuba uhlala usenza iiprojekthi zokulungisa imingxunya, ngaba usoloko unemibuzo efana nale: Kutheni i-10mm drill bit yam ivelisa umngxuma we-10.1mm? okanye Kutheni i-drill bits zam zaphuka lula kangaka?
Kwiimeko ezininzi, ingxaki ayikokuba nzima ngokwaneleyo ukubhola, kodwa kukubaleka kwe-radial engabonakaliyo.
Kweli nqaku, siza kuchaza ukuba yintoni i-runout kunye nesizathu sokuba ibaluleke ngamazwi alula.
Yintoni i-runout?
Ngamafutshane, i-runout ibhekisa ekugungqeni okanye ekushukumeni kwe-drill bit ngexesha lokujikeleza.
Khawucinge ngokujikeleza okugqibeleleyo. Xa i-drill bit ijikeleza ngaphakathi komatshini, umgca wayo ophakathi kufuneka uhambelane ngokugqibeleleyo nomgca ophakathi we-spindle yomatshini. Ngeli xesha, i-drill bit ibonakala ingashukumi kwaye izinzile kakhulu.
Nangona kunjalo, ukuba iqhekeza lokubhola liphazanyiswe kancinci okanye i-machine chuck ayilunganga kakuhle embindini, incam yokubhola iya kulandelela indlela ejikelezayo njengoko ijikeleza. Ubukhulu bale ntshukumo yokungcangcazela bubizwa ngokuba yi-runout.
Zithini iingxaki zokubaleka kwebhola?
Kwi-high-speed steel (HSS) twist drills, ukuxinana okukhulu kubi kakhulu. Kubangela iingxaki ezininzi:
1. Imingxunya emikhulu kakhulu (imingxunya emikhulu): Le yeyona ngxaki ixhaphakileyo. Ngenxa yokuba i-drill iyaxengaxenga, inqumla indawo enkulu kunobubanzi bayo.
2. Iindonga ezinemingxunya erhabaxa: I-drill eqhaqhazelayo ikrwela iindonga zangaphakathi zomngxuma, nto leyo ebangela ukuba umphezulu orhabaxa ube rhabaxa. Umngxuma usenokulahlekelwa bubungqukuva bawo kwaye ube yi-elliptical.
3. Ubomi bokubhola obunciphileyo: Ukusasazwa kwamandla okungalinganiyo kuzo zombini iikona zokusika ngenxa yokushukuma kubangela ukuba olunye uhlangothi lusebenze kakhulu, nto leyo ebangela ukuba ukonakala ngokukhawuleza nokudinwa.
4. Umngcipheko ophezulu wokwaphuka kwe-drill: Ukuvuza kwe-radial kuvelisa ukungcangcazela okukhulu. Xa kugqojozwa imingxuma enzulu, oku kungcangcazela kuyaphula lula i-drill.
Kutheni kwenzeka ukuqunjelwa?
Ukuqhushumba kwe-drill akusoloko kuyingxaki ye-drill bit. Ngokuqhelekileyo yingxaki yenkqubo:
• Iingxaki zezixhobo zomatshini okanye i-chuck: Ngaba i-drill chuck yakho ingcolile ngeetships zesinyithi? Ngaba i-chuck yonakele kakhulu? Le yeyona ngxaki ixhaphakileyo. Ukuxinwa okungafanelekanga kuya kubangela ukuba i-drill bit inyibilike.
• Iingxaki zokufakela: I-drill bit iphuma kakhulu okanye ayibotshelelwanga ngokukhuselekileyo.
• I-drill bit ngokwayo: Kakade ke, ezinye ii-bits ezikumgangatho ophantsi zinokuba zigobile ngokwemvelo okanye zibe nemiphetho yokusika engalinganiyo. ngakumbi, ii-twist drills zenziwa kusetyenziswa iinkqubo ezimbini: ukuqengqeleka kunye nokusila. Ii-ground drills zihlala zine-runout engcono kunee-rolled drills.
Ungayichonga njani?
Kukho iindlela ezimbini eziphambili zokufumanisa ukugqobhoza: ukujonga okubonakalayo okulula kunye nokulinganisa ngokuchanekileyo. Eyona ndlela ilula yokujonga okubonakalayo kukufaka i-drill bit uze uyijikelezise ngesantya esiphantsi uze ujonge incam yokugqobhoza ngenqanaba lamehlo akho. Ukuba incam yokugqobhoza ibonakala icacile kwaye izinzile, kuyinto eqhelekileyo; ukuba kukho ukubona kabini, ukufiphala, okanye ukwanda okubonakalayo "kwesangqa esijikelezayo", oko kubonisa ukugqobhoza okukhulu.
Indlela echanekileyo ngakumbi ibandakanya ukusebenzisa isalathisi sokudayela (okanye i-micrometer): qala ubambe i-drill bit ngokukhuselekileyo, uze ubeke i-indicator probe nxamnye nomphetho wokusika okanye indawo egudileyo ye-shank. Jikelezisa i-spindle ngesandla isangqa esinye esipheleleyo uze urekhode umahluko phakathi kwamaxabiso aphezulu kunye nawona mancinci aboniswe yi-pointer. Lo mahluko umele i-total indicator runout (TIR).
Ingcebiso yethu
Xa senza iidrili zentsimbi ezijijekileyo ngesantya esiphezulu, sinemigangatho engqongqo yokuvavanya ukuba umzimba wedrili uqondile kwaye ulungelelene kangakanani na, siqinisekisa ukuba yonke into ejijekileyo iyahlangabezana nemigangatho echanekileyo ngaphambi kokuba siphume kwifektri yethu.
Kwakhona, ihashe elilungileyo lifanelwe yisihlalo esihle. Ukuze ufumane iziphumo ezigqibeleleyo zokubhola, nceda ukhumbule ukucoca nokujonga ityhubhu yesixhobo sakho somatshini rhoqo!
