I-HSS Asme Extra Long Drill Bit

Incazelo emfushane:

Lona umshini wokubhoboza insimbi onesivinini esikhulu ofanele ukusetshenzwa ngezimbobo nezimbobo ezimaphakathi ensimbi yengxubevange, insimbi emnene, izinsimbi ezingezona ayoni, insimbi ekhonjiwe, i-cast iron, ipulasitiki, izinkuni nezinye izinto.Nakuba izinsimbi ezithatha isikhathi eside zingasetshenziswa emishinini emile, ngokuvamile zisetshenziswa ekuzilolongeni okubanjwa ngesandla ukuze kungene izindawo okunzima ukuzifinyelela lapho ukubhola okude kungakwazi.Le drill ifanele izimbobo zokubhoboza ezingeke zenziwe nge-dresser noma i-taper drill, okwenza kube elinye lamathuluzi ahlukahlukene kakhulu.Izingcezu zokubhola zensimbi ezinesivinini esiphezulu zilungele ukusetshenziswa okujwayelekile, okuhlinzeka ngenhlanganisela yobulukhuni nokuqina kokumelana nokugqokwa.

Umbukiso Womkhiqizo

Ngokungeziwe ekukhuliseni ukuthambisa, ukwelashwa kwe-oxide emnyama futhi kudala amaphakethe amancane endaweni yamathuluzi akwazi ukubamba isipholile eduze komkhawulo wokusika isikhathi eside.Njengomphumela wokwelashwa kwe-black oxide surface kunsimbi enesivinini esikhulu, ithuluzi liyathuthukiswa ekumelana nokushisa futhi linwetshwe empilweni yalo yamathuluzi, ngongqimba lwe-oxide oluncane kunalolo oluvame ukusetshenziselwa ukukhomba amathuluzi ensimbi ye-cobalt;ukusebenza kwayo kufana nokwamathuluzi angagqokile.Kungenzeka ukusebenzisa ama-shanks ayindilinga anezinhlobo eziningi ezahlukene zabaphathi bamathuluzi.

Ama-drill anephuzu elihlukanisiwe lama-degree angu-118 noma angu-135 asho amandla amancane adingekayo ukuze ubhoboze ku-workpiece, ukuvimbela umshini wokubhoboza ukuthi ungasheleli phezu kwezinto ezisetshenziswayo, ukuzinikela ngokwakho kanye nokunciphisa ukugxila okudingekayo ukuze ubhoboze.Lokhu kuprakthiza kunomklamo oyingqayizivele onethiphu eligxile kuwe elivimbela ukushelela, ukwenza umsebenzi usheshe futhi ube lula.Ukwenyuka kwesivinini sokubhoboza kusho ukushisa okuncane okukhiqizwayo futhi kufinyelelwa ukuguga okwengeziwe, okunweba impilo yokubhoboza.Unqenqema lokusika luhlala lubukhali futhi lumelana nokusetshenziswa okuqhubekayo.Uma zisebenza ngendlela ephambene newashi (ukusika kwesokudla), abasiki be-helical-fluted bakhipha ama-chips phezulu ngokusikwa ukuze kuncishiswe ukuvala.
