1.Band blade ububanzi

Ububanzi be-blade ngumlinganiselo ukusuka phezulu kwezinyo ukuya kumphetho ongasemva wencakuba. Iincakuba ezibanzi ziqinile ngokubanzi (isinyithi esingaphezulu) kwaye zithande ukulandela umkhondo ngcono kumavili ebhendi kuneencakuba ezimxinwa. Xa usika izinto ezityebileyo, i-blade ebanzi inamandla amancinci okuphambuka ngenxa yokuba umva wokugqibela, xa usikiwe, unceda ukuqhubela phambili kwi-blade, ngakumbi ukuba ukukhutshwa kwecala akugqithisi. (Njengendawo yereferensi, sinokubiza iblade eyi-1/4 ukuya kwi-3/8 intshi ngobubanzi “incakuba yobubanzi obuphakathi”.)

Inqaku elikhethekileyo: Xa uphinda usarha iqhekeza lomthi (oko kukuthi, ukulenza libe ziziqwenga ezibini ezinobungqingqwa njengeyantlandlolo), iblade emxinwa ngokwenene iya kusika ngokuthe ngqo kunencakuba ebanzi. Amandla okusika aya kwenza ukuba i-blade ebanzi iphambuke emacaleni, ngelixa i-blade emxinwa, i-force iya kuyityhala ngasemva, kodwa ingabi ngasecaleni. Oku ayisiyiyo into enokulindelwa, kodwa yinyani ngokwenene.

Iincakuba ezimxinwa zinokuthi, xa zisika igophe, zisike ijiko leradiyasi elincinane kunencakuba ebanzi. Umzekelo, i-¾-intshi-i-blade ebanzi inokusika i-5-1/2-intshi yeradiyasi (malunga) ngelixa i-3/16-intshi yeblade inokusika i-5/16-intshi yeradiyasi (malunga nobukhulu bedime). (Qaphela: I-kerf imisela i-radius, ngoko ke le mizekelo mibini ngamaxabiso aqhelekileyo. I-kerf ebanzi, ethetha uthuli lwamaplanga kunye ne-slot ebanzi, ivumela ukusikwa kwe-radius encinci kune-kerf emxinwa. Kodwa i-kerf ebanzi ithetha ukuba ukusika okuthe tye kuya kuba rhabaxa kwaye ubhadula ngakumbi.)

Xa usarha amaplanga aqinileyo kunye noxinaniso oluphezulu lwemithi ethambileyo efana ne-Southern yellow pine, ndikhetha ukusebenzisa iblade ebanzi kangangoko; Umthi ophantsi woxinaniso unokusebenzisa i-blade encinci, ukuba ifunwa.

2.Band blade ubukhulu

Ngokubanzi, i-blade ityebile, kokukhona uxinzelelo olunokuthi lusetyenziswe. Iincakuba ezityebileyo nazo zizincakuba ezibanzi. Ukuxinana okungaphezulu kuthetha ukusikwa okuthe ngqo. Nangona kunjalo, iiblades ezishinyeneyo zithetha uthuli lwamaplanga. Iiblade ezishinyeneyo zikwanzima kakhulu ukugoba malunga namavili ebhendi, ngoko ke uninzi lwabavelisi beesarha baya kuchaza ukutyeba okanye uluhlu lokutyeba. Amavili ebhanti amancinci amancinci afuna iincakuba ezibhityileyo. Umzekelo, ivili le-12-intshi ububanzi lihlala lixhotyiswe nge-0.025-intshi ubukhulu (ubuninzi) blade eyi-intshi eyi-½ okanye encinci. I-18-intshi ye-diameter yevili ingasebenzisa i-0.032-intshi yeblade etyebileyo eyi ¾ intshi ububanzi.

Ngokubanzi, iiblades ezityebileyo kunye ezibanzi ziya kuba yinto ekhethekileyo xa ubona iinkuni ezixineneyo kunye neenkuni ezinamaqhina aqinileyo. Ukhuni olunjalo ludinga ukomelela okongeziweyo kwe-blade ebanzi, ebanzi ukuphepha ukuphuka. Iincakuba ezishinyeneyo nazo ziyaphambuka kancinci xa usarha kwakhona.
