Ukugrumba yindlela eqhelekileyo yokwenziwa kwemveliso.Xa kuthengwa i-drill bits, i-drill bits iza kwizinto ezahlukeneyo kunye nemibala eyahlukeneyo.Ke inceda njani imibala eyahlukeneyo ye-drill bits?Ngaba umbala unento yokwenza nomgangatho we-drill bit?Ngowuphi umbala we-drill bit engcono ukuyithenga?
Okokuqala, kufuneka sicacise ukuba umgangatho we-drill bit awukwazi ukugwetywa nje ngombala wayo.Akukho budlelwane buthe ngqo kwaye bungenakuphepheka phakathi kombala kunye nomgangatho.Imibala eyahlukeneyo ye-drill bits ingenxa yeendlela ezahlukeneyo zokucwangcisa.Ewe kunjalo, singenza ugwebo olurhabaxa olusekwe kumbala, kodwa iintwana zanamhlanje ezikumgangatho ophantsi ziya kuphinda ziqhubele eyazo imibala ukuze zifezekiseke inkangeleko yomgangatho ophezulu wokubhola.
Ke yintoni umahluko phakathi kwamasuntswana edrill enemibala eyahlukeneyo?
Iziqwenga zentsimbi ezikumgangatho ophezulu eziphantsi ngokupheleleyo zifumaneka kumhlophe.Kakade ke, i-rolled drill bit nayo inokwenziwa mhlophe ngokucolwa kakuhle isangqa sangaphandle.Yintoni eyenza ukuba umgangatho ophezulu ungabi yinto kuphela ngokwayo, kodwa kunye nokulawula umgangatho ngexesha lokugaya.Ingqongqo kwaye akusayi kubakho kutsha kumphezulu wesixhobo.Ezimnyama zii-Nitride drill bits.Yindlela yeekhemikhali ebeka isixhobo esigqityiweyo kumxube we-ammonia kunye nomphunga wamanzi kwaye yenza unyango lokulondoloza ukushisa kwi-540 ~ 560C ° ukuphucula ukuqina kwesixhobo.Uninzi lwamasuntswana amnyama okubhola okwangoku akwimarike amnyama kuphela ngombala (ukwenzela ukugquma ukutsha okanye ulusu olumnyama kumphezulu wesixhobo), kodwa eyona mpembelelo yokusetyenziswa ayiphucukanga ngokusebenzayo.
Kukho iinkqubo ezi-3 zokuvelisa i-drill bits.Ukuqengqeleka okumnyama kokona kubi.Ezimhlophe zineencam ezicacileyo nezikhazimlisiweyo.Ekubeni i-oxidation yobushushu obuphezulu ingafuneki, isakhiwo senkozo yentsimbi asiyi kutshatyalaliswa, sinokusetyenziselwa ukugaya izixhobo zokusebenza ezinobunzima obuphezulu.Amasuntswana e-Yellow-brown drill aqukethe i-cobalt, umthetho ongathethwayo kwishishini le-drill bit.Iidayimani ezine-Cobalt zimhlophe ekuqaleni, kodwa kamva ziye zenziwa iathom ibe tyheli-mdaka (eyaziwa ngokuba yi-amber).Zezinye zezona zihamba phambili ngoku zisasazwa.I-M35 (Co 5%) ikwanayo nombala wegolide obizwa ngokuba yi-titanium-plated drill bit, eyahlulahlulwe ngokweengubo zokuhombisa kunye nokwaleka kwimizi-mveliso.I-decorative plating ayintle, ikhangeleka intle.Isiphumo se-industrial electroplating sihle kakhulu.Ukuqina kunokufikelela kwi-HRC78, engaphezulu kunobulukhuni be-cobalt drill (HRC54 °).
Indlela yokukhetha i-drill bit
Ekubeni umbala awuyiyo inqobo yokugweba umgangatho we-drill bit, indlela yokukhetha i-drill bit?
Ngokusuka kumava, xa sithetha ngokubanzi, amasuntswana okubhola amhlophe adla ngokucolwa ngokupheleleyo ngesantya esiphezulu kwaye kufuneka abe nowona mgangatho uphezulu.Ezo zegolide zine-titanium nitride coating kwaye zidla ngokuba zezona zigqwesileyo okanye ezimbi kwaye zinokukhohlisa abantu.Umgangatho wobumnyama nawo uyahluka.Abanye basebenzisa izixhobo zekhabhoni ezikumgangatho ophantsi, ekulula ukuzibamba kunye nokugqwala, ngoko ke kufuneka wenziwe mnyama.
Kukho uphawu lokurhweba kunye nokunyamezela ukuphawula ububanzi kwi-shank ye-drill bit, ehlala icacile, kwaye umgangatho we-laser kunye ne-electro-etching akufanele ube mbi kakhulu.Ukuba iimpawu ezibunjiweyo zinemiphetho yeconvex, oko kubonisa ukuba isuntswana le-drill likumgangatho ophantsi, kuba ulwandlalo lweconvex lwabalinganiswa luya kubangela ukuchaneka kwe-drill bit clamping kusilele ukuhlangabezana neemfuno.Umphetho wegama uxhunywe kakuhle kwi-cylindrical surface ye-workpiece, kunye ne-drill bit enomphetho ocacileyo wegama ngumgangatho omhle.Kuya kufuneka ujonge i-drill bit enomphetho olungileyo wokusika kwincam.Ukugrumba umhlaba ngokupheleleyo kunemiphetho emihle kakhulu yokusika kwaye ihlangabezana neemfuno zomgangatho we-helix, ngelixa iidrill ezikumgangatho ophantsi zinendawo yokucolwa engalunganga.
