Ndikhetha Njani iBlede yokuSarha eLungileyo

Ukwenza amanxeba agudileyo, akhuselekileyo ngesarha yetafile yakho, isarha ye-radial-arm, isarha yokunqunqa okanye isarha edibeneyo yokutyibilika kuxhomekeke ekubeni nencakuba echanekileyo yesixhobo kunye nohlobo lokusikwa ofuna ukulenza. Akukho kunqongophala kokhetho olusemgangathweni, kwaye umthamo opheleleyo wamacwecwe akhoyo unokudida nomchweli onamava.

Iza kusetyenziswa koluphi uhlobo isarha? Ezinye iincakuba ziyilelwe ukuba zisetyenziswe kwiisarha ezithile, ngoko ke uya kufuna ukuqiniseka ukuba ufumana iblade elungileyo yesixhobo. Ukusebenzisa uhlobo olungalunganga lweblade kwisarha kusenokwenzeka ukuba kuvelise iziphumo ezibi kwaye kusenokuba yingozi kwezinye iimeko.

Zeziphi izinto eziya kusetyenziselwa ukusika incakuba? Ukuba ufuna ukusika uluhlu olubanzi lwezixhobo, oko kuya kuchaphazela ukhetho lwakho. Ukuba usike uhlobo olunye lwemathiriyeli (imelamine, umzekelo) olo lwazi lunokuchaphazela ukhetho lwakho.

I-Saw Blade Essentials I-Saw blade ezininzi ziyilelwe ukubonelela ngezona ziphumo zingcono kumsebenzi othile wokusika. Unokufumana iiblade ezikhethekileyo zokukrazula amaplanga, ukunqumla amaplanga, ukusika i-plywood ene-veneered kunye neepaneli, ukusika i-laminates kunye neeplastiki, ukusika i-melamine kunye nokusika iintsimbi ezingenayo i-ferrous.

Uninzi lwee-saw blades zenzelwe ukubonelela ngeziphumo zabo ezilungileyo kumsebenzi othile wokusika. Unokufumana iiblade ezikhethekileyo zokukrazula amaplanga, ukunqumla amaplanga, ukusika i-plywood ene-veneered kunye neepaneli, ukusika i-laminates kunye neeplastiki, ukusika i-melamine kunye nokusika iintsimbi ezingenayo i-ferrous. Kukwakho injongo ngokubanzi kunye neeblades ezidityanisiweyo, eziyilelwe ukusebenza kakuhle kwiintlobo ezimbini okanye ngaphezulu zokusikwa. (Iincakuba ezidityanisiweyo ziyilelwe ukunqumla kunye nokukrazula.

Iincakuba zenjongo ngokubanzi ziyilelwe ukwenza zonke iindidi zokusikeka, kuqukwa neplywood, iplanga elaminethiweyo kunye nemelamine.) Eyona blade yenza ngcono igqitywe, ngokuyinxenye, linani lamazinyo, ubungakanani bomthungo, ubume bezinyo i-hook angle (i-angle yezinyo).

Ngokuqhelekileyo, iincakuba ezinamazinyo amaninzi ziphuma lula, yaye amazinyo anamazinyo ambalwa akhupha izinto ngokukhawuleza. I-10 ″ blade eyenzelwe ukukrazula amaplanga, umzekelo, idla ngokuba namazinyo angama-24 kwaye yenzelwe ukususa ngokukhawuleza izinto kunye nobude beenkozo. I-blade yokukrazula ayilungiselelwe ukuba ivelise isibuko esisikiweyo, kodwa i-blade efanelekileyo yokukrazula iya kuhamba ngomthi onzima kunye nomzamo omncinci kwaye ushiye ukusika okucocekileyo kunye namanqaku amancinci.

Kwelinye icala, iblade ebizwa ngokuba yi-crosscut blade, yenzelwe ukuvelisa ukusika okugudileyo kwiinkozo zomthi, ngaphandle kokuqhekeka okanye ukukrazuka. Olu hlobo lwencakuba ludla ngokuba namazinyo angama-60 ukuya kwangama-80, kwaye inani eliphezulu lamazinyo lithetha ukuba izinyo ngalinye kufuneka likhuphe izinto ezincinci. I-crosscut blade yenza ukusika kwabantu abaninzi ngakumbi njengoko ihamba kwisitokhwe kune-blade yokukrazula kwaye, ngenxa yoko, ifuna isantya sokutya esicothayo. Isiphumo kukusikwa okucocekileyo kumaphethelo kunye nomgangatho osikiweyo. Ngomgangatho ophezulu we-crosscut blade, umphezulu osikiweyo uya kubonakala uphucukile.

Umbhobho sisithuba esiphambi kwezinyo ngalinye esivumela ukususwa kwetshiphu. Kumsebenzi wokukrazula, umyinge wesondlo uyakhawuleza kwaye ubungakanani betshiphu bukhulu, ngoko ke umgudu kufuneka ube nzulu ngokwaneleyo kubuninzi bemathiriyeli ekufuneka iwuphathe. Kwi-blade yokunqumla, ii-chips zincinci kwaye zincinci ngezinyo, ngoko i-gullet incinci kakhulu. Imibhobho kwezinye iincakuba ezinqamlezileyo nazo zenziwa ubungakanani obuncinci ngenjongo ukunqanda umyinge wesondlo okhawuleza kakhulu, nto leyo enokuba yingxaki ingakumbi kwiisarha ze-radial-arm kunye ne-sliding miter. Imingxuma emikhulu phakathi kwamaqela amazinyo inceda ekukhupheni izixa ezikhulu zezinto eziveliswe ekukrazuleni. Imingxuma emincinci phakathi kwamazinyo adibeneyo ithintela isantya sokutya esikhawuleza kakhulu ekunqumleni.

Ii-sawblades ezijikelezayo ziza noluhlu olubanzi lwamanani amazinyo, yonke into ukusuka kwi-14 ukuya kwi-120 yamazinyo. Ukufumana amanxeba acocekileyo, sebenzisa i-blade enenani elichanekileyo lamazinyo kwisicelo esinikezelweyo. Isixhobo esisikwayo, ubukhulu bayo, kunye necala lenkozo xa lithelekiswa nesarha kunceda ukufumanisa ukuba yeyiphi iblade eyona ilungileyo. Mhlawumbi into ephambili ekufuneka uyiqwalasele xa ukhetha i-sawblade yisiphumo esifunwayo. Iblade enezinyo ezisezantsi ithande ukusika ngokukhawuleza kunencakuba enenani eliphezulu lamazinyo, kodwa umgangatho wokusikwa urhabaxa, akukhathaliseki nokuba uyifreyimu. Ngakolunye uhlangothi, i-blade enezinyo eliphezulu kakhulu kwisicelo ivelisa ukusika okucothayo okugqiba ukutshisa izinto eziphathekayo, okungekho umenzi wekhabhinethi unokunyamezela.

Iblade enamazinyo ambalwa njenge-14 isika ngokukhawuleza, kodwa ngokurhabaxa. Ezi blades zikrazula nakwesona sitokhwe sishinyeneyo ngokulula, kodwa ukusetyenziswa kwazo kulinganiselwe. Ukuba uzama ukusika iimpahla ezicekethekileyo zeshiti ngencakuba enamazinyo angaphantsi kwama-24, uya kuyicola loo nto.

Iblade yokuqulunqa ngokubanzi.eyona iza neninzi ye-71.4-in. isarha sesetyhula.inamazinyo angama-24 kwaye inika i-rip cut entle ecocekileyo kodwa i-rougher crosscut. Ukuba wenza ifreyimu yesitokhwe se-2x, apho ukuchaneka kunye nokucoceka kokusikwa kukwesibini kwisantya kunye nokulula kokusikwa, inokuba kuphela kweblawudi oya kuyidinga.

Iblade yamazinyo angama-40 isebenza kakuhle kuninzi lokusikeka kwiplywood. Amagqabi anamazinyo angama-60 okanye angama-80 kufuneka asetyenziswe kwiplywood eveyiweyo kunye nemelamine, apho iingcango ezicekethekileyo zinokuphephetheka kumzantsi wesikiweyo, uphawu olwaziwa ngokuba yi tearout. I-MDF ifuna amazinyo angaphezulu (ama-90 ukuya kwi-120) ukuze ufumane awona mazinyo acocekileyo.

Ukuba wenza umsebenzi omninzi wokugqiba-ufakela ukubumba isithsaba, umzekelo-udinga ukusika okucocekileyo okudinga amazinyo amaninzi. Ukusika iimitha kukunqumlana kwi-engile, kwaye iincakuba ezinobalo lwamazinyo oluphezulu zisebenza ngcono xa zisikwa ngapha kweenkozo. Iblade enamazinyo angama-80 okanye ngaphezulu inika ukusika kwemiter ekrwada oyifunayo.
