Ukusika akuwona umsebenzi wamandla aqatha: Sebenzisa ama-blade e-carbide band saw ukuze ufeze ukucubungula okuhlakaniphile
Lapho kusahwa izinto okunzima ukuzicubungula (njenge-titanium alloys, insimbi engagqwali, i-alloys engashisi ukushisa kanye nezinsimbi eziqiniswe ebusweni), ama-carbide tooth band saw blades asephenduke amathuluzi asetshenziswa kabanzi ngenxa yobuhle bawo obuhle kakhuluukusikaukusebenza kahle nokuqina. Eminyakeni yamuva nje, abasebenzisi abaningi baqale ukuzisebenzisa ekucutshungulweni kwezinto ezivamile futhi bathole ukuthi zinesivinini sokusika esisheshayo, ukuqeda kahle ubuso, futhi zingandisa impilo yesevisi cishe ngo-20% uma kuqhathaniswa nama-blade e-saw e-bimetallic avamile.
1. Isakhiwo samazinyo kanye ne-geometry
Izimo zamazinyo ezivamile zama-blade e-carbide band saw zihlanganisa ukusika amazinyo amathathu kanye namazinyo okugaya e-trapezoidal. Phakathi kwazo, isimo samazinyo okusika amazinyo amathathu sivame ukusebenzisa ukwakheka kwe-angle ye-rake enhle, okusiza "ukuluma" ngokushesha izinto bese kwakha ama-chips ezintweni ezinamandla noma ezinzima, futhi kufanelekile ezimweni zokukhiqiza eziphumelelayo. Lapho kucutshungulwa izinto eziqinile ebusweni (njengezinduku zesilinda noma imiphini ye-hydraulic), kunconywa kakhulu ukusebenzisa isimo samazinyo se-angle ye-rake engalungile. Lesi sakhiwo sisiza "ukusunduza" ungqimba oluqinile ebusweni ngaphansi kwezimo zokushisa okuphezulu, ngaleyo ndlela siqede ukusika kahle.
Kwezinto ezihudulayo ezifana ne-casti-aluminium, ama-band saw blades ane-tooth pitch ebanzi kanye nomklamo we-cutting groove obanzi afaneleka kakhulu, okunganciphisa ngempumelelo amandla okubopha kwezinto ezingemuva kwe-saw blade futhi kwandise impilo yamathuluzi.
2. Izinhlobo ezahlukene ze-saw blade kanye nobubanzi bazo obufanele
· Izinto ezincane ezinobubanzi (<152mm): Zifanelekela ama-carbide saw blades anesakhiwo samazinyo amathathu kanye nesimo samazinyo esiqondile se-rake angle, kanye nokusebenza kahle kokusika kanye nokuzivumelanisa nezimo kwezinto.
· Izinto ezinkulu ezinobubanzi: Kunconywa ukusebenzisa ama-saw blades anomklamo onqenqemeni oluningi, ngokuvamile ukugaya izindawo zokusika ezifika kwezinhlanu esicongweni ngasinye sezinyo ukuze kuthuthukiswe ikhono lokusika nokuthuthukisa izinga lokususa izinto.
· Ihadiwe yokuqinisa ubuso: I-Negative rake angle kanye nama-saw blades anamazinyo amathathu kufanele akhethwe, okungafinyelela ukusika okushisa okuphezulu kanye nokususwa kwama-chip ngokushesha, futhi kunqume ngempumelelo igobolondo eliqinile langaphandle.
· Izinsimbi ezingezona i-ferrous kanye ne-aluminium ephothiwe: Zifanelekela ama-saw blades anomklamo obanzi wokugoba kwamazinyo ukuze kugwenywe ukubanjwa okugobile nokunciphisa ukwehluleka kusenesikhathi.
· Izimo zokusika ezijwayelekile: Kunconywa ukusebenzisa ama-blade e-carbide band saw ajwayelekile anomumo wezinyo ongathathi hlangothi noma omncane one-positive rake angle, afanelekela izinhlobo ezahlukene zezinto zokwakha kanye nezidingo zokusika.
3. Ithonya lohlobo lwamazinyo ekhwalithini yokusika
Izinhlobo ezahlukene zamazinyo zihambisana nezindlela ezahlukene zokwakheka kwama-chip. Isibonelo, umklamo owodwa usebenzisa amazinyo amane aphansi ukwakha ama-chip ayisikhombisa. Ngesikhathi senqubo yokusika, izinyo ngalinye labelana ngokulinganayo ngomthwalo, okusiza ukuthola indawo yokusika ebushelelezi neqondile. Omunye umklamo usebenzisa isakhiwo samazinyo amathathu ukusika ama-chip amahlanu. Nakuba ukugoba kobuso kuphakeme kancane, isivinini sokusika siyashesha, okufanelekela izimo zokucubungula lapho ukusebenza kahle kubekwa phambili.
4. Ukumboza nokupholisa
Amanye ama-blade esaha se-carbide anikeza izembozo ezengeziwe, njenge-titanium nitride (TiN) kanye ne-aluminium titanium nitride (AlTiN), ukuthuthukisa ukumelana nokuguguleka kanye nokumelana nokushisa, futhi afanele ukusetshenziswa okusheshayo nokuphakelwa okuphezulu. Kubalulekile ukuqaphela ukuthi izembozo ezahlukene zifanele izimo zokusebenza ezahlukene, nokuthi ukusebenzisa izembozo kudinga ukucatshangelwa ngokuphelele ngokusekelwe ezimweni ezithile zokusetshenziswa.
