Ukusika akuwona umsebenzi we-brute force: Sebenzisa i-carbide band saw blades ukuze ufeze ukucubungula okuhlakaniphile
Lapho usaha izinto okunzima ukuzisebenzisa (njenge-titanium alloys, insimbi engagqwali, ama-alloys ukumelana nokushisa nezinsimbi eziqinile), amasaha ebhande le-carbide tooth band asephenduke amathuluzi asetshenziswa kakhulu ngenxa yobuhle bawo.ukusikaukusebenza kahle nokuqina. Eminyakeni yamuva, abasebenzisi abaningi baye baqala ukuzisebenzisa ekucutshungulweni kwezinto ezijwayelekile futhi bathola ukuthi banesivinini sokusika ngokushesha, ukuqeda kahle kwendawo, futhi bangakhuphula impilo yesevisi cishe ngo-20% uma kuqhathaniswa nama-saw blades endabuko e-bimetallic.
1. Ukwakheka kwezinyo kanye nejometri
Izinyo ezivamile zomumo we-carbide band saw blades zihlanganisa ukusika amazinyo amathathu kanye namazinyo okugaya e-trapezoidal. Phakathi kwazo, ukwakheka kwamazinyo okusika amazinyo amathathu ngokuvamile kuthatha umklamo omuhle we-rake angle, okusiza ukushesha "ukuluma" izinto futhi wenze ama-chips ezintweni eziqinile noma ezinobunzima obukhulu, futhi ifanele izimo zokukhiqiza eziphumelelayo. Lapho ucubungula izinto eziqiniswe phezulu (njengezigxobo zesilinda noma ama-hydraulic shafts), kutuswa kakhulu ukusebenzisa umumo wezinyo le-rake angle elingalungile. Lesi sakhiwo sisiza "ukucindezela" ungqimba oluqinile ngaphansi kwezimo ezishisa kakhulu, ngaleyo ndlela kugcwalise ukusika kahle.
Okwezinto eziqhumayo ezifana nokuphonswai-aluminium, ama-band saw blades ane-wide tooth pitch kanye ne-wide cutting groove design afaneleka kakhulu, anganciphisa ngempumelelo amandla okugoqa wento engemuva kwesaha futhi andise impilo yamathuluzi.
2. Izinhlobo ezahlukene zamasaha kanye nobubanzi bazo obusebenzayo
· Izinto ezisetshenziswayo ezinobubanzi obuncane (<152mm): Ifanele izindwani zesaha ze-carbide ezinesakhiwo samazinyo amathathu kanye nezinyo eliphozithivu le-rake angle, elisebenza kahle kakhulu lokusika nokuvumelana nezimo.
· Izinto ezinobubanzi obukhulu: Kunconywa ukusebenzisa ama-saha ama-saha anomklamo onama-multi-edge, ngokuvamile ugaya izindawo zokusika ezifika ezinhlanu kuthiphu lezinyo ngalinye ukuze kuthuthukiswe ikhono lokusika futhi kuthuthukiswe izinga lokususa izinto.
· Izingxenyekazi zekhompuyutha eziqinisa ubuso: I-rake angle engalungile kanye nama-saw blades anamazinyo amathathu kufanele kukhethwe, okungafinyelela ukusika okuphezulu nokususwa kwe-chip ngokushesha, futhi kusikwe ngempumelelo igobolondo eliqinile langaphandle.
· Izinsimbi ezingenayo insimbi ne-aluminium ecijile: Ifanele ama-saha anomklamo obanzi wezinyo ukuze kugwenywe ukugoqana nokunciphisa ukwehluleka kwangaphambi kwesikhathi.
· Izimo ezijwayelekile zokusika: Kunconywa ukusebenzisa amasaha ebhande elijwayelekile le-carbide anesimo sezinyo le-rake engela hlangothi noma elincane eliphozithivu, elifanele ukuhlukahluka kwempahla kanye nezidingo zokusika.
3. Umthelela wohlobo lwamazinyo kwikhwalithi yokusika
Izinhlobo ezahlukene zamazinyo zihambisana nezindlela ezihlukene zokwakheka kwe-chip. Ngokwesibonelo, idizayini eyodwa isebenzisa amazinyo amane aphansi ukuze kwakhe ama-chips ayisikhombisa. Phakathi nenqubo yokusika, izinyo ngalinye lihlanganyela ngokulinganayo umthwalo, okusiza ukuthola indawo yokusika elula futhi eqondile. Omunye umklamo usebenzisa isakhiwo samazinyo amathathu ukusika ama-chips amahlanu. Nakuba ubulukhuni bangaphezulu buphakeme kancane, ijubane lokusika liyashesha, elifanele ukucubungula izimo lapho ukusebenza kahle kubekwa phambili.
4. Ukumboza nokupholisa
Amanye ama-carbide saw blades ahlinzeka ngezingubo ezengeziwe, ezifana ne-titanium nitride (TiN) ne-aluminium titanium nitride (i-AlTiN), ukuthuthukisa ukumelana nokugqoka nokumelana nokushisa, futhi ifanele izicelo zejubane eliphezulu nezokudla okuphezulu. Kuyaqapheleka ukuthi izimbotshana ezihlukene zifanele izimo zokusebenza ezihlukene, futhi ukuthi ngabe ukusebenzisa izigqoko kudinga ukucatshangelwa ngokuphelele ngokusekelwe ezimweni ezithile zohlelo lokusebenza.
