Ndingayikhetha njani iBlade yeSaw efanelekileyo

Ukwenza iziqwenga ezigudileyo nezikhuselekileyo ngesarha yakho yetafile, isarha yesandla esijikelezayo, isarha yokusika okanye isarha yemiter edibeneyo etyibilikayo kuxhomekeke ekubeni neblade efanelekileyo yesixhobo kunye nohlobo lokusika ofuna ukulwenza. Akukho kunqongophala kweendlela zokukhetha ezisemgangathweni, kwaye ubungakanani beeblade ezikhoyo bunokudida nomchweli onamava.

Iblade iza kusetyenziswa kuhlobo luni lwesarha? Amanye amablade enzelwe ukusetyenziswa kwiisarha ezithile, ngoko ke kuya kufuneka uqiniseke ukuba ufumana iblade efanelekileyo yesixhobo. Ukusebenzisa uhlobo olungalunganga lweblade kwisarha kunokubangela iziphumo ezimbi kwaye kwezinye iimeko kunokuba yingozi.

Zeziphi izinto eziza kusetyenziswa i-blade ukusika? Ukuba ufuna ukusika uluhlu olubanzi lwezinto, oko kuya kuchaphazela ukhetho lwakho. Ukuba usika uhlobo olunye lwezinto (umzekelo, i-melamine) olo lwazi lunokuchaphazela ukhetho lwakho.

Izinto Ezibalulekileyo Zesarha Iiblade ezininzi zesarha zenzelwe ukubonelela ngeziphumo zazo ezilungileyo kumsebenzi othile wokusika. Ungafumana iiblade ezikhethekileyo zokukrazula imithi, ukusika imithi enqamlezileyo, ukusika iplywood ene-veneered kunye neepaneli, ukusika iilaminates kunye neeplastiki, ukusika i-melamine kunye nokusika iintsimbi ezingezizo i-ferrous.

Iiblade ezininzi zesarha zenzelwe ukubonelela ngeziphumo zazo ezilungileyo kumsebenzi othile wokusika. Ungafumana iiblade ezikhethekileyo zokukrazula imithi, ukusika imithi enqamlezileyo, ukusika iplywood ene-veneered kunye neepaneli, ukusika iilaminate kunye neeplastiki, ukusika i-melamine kunye nokusika iintsimbi ezingezizo i-ferrous. Kukwakho neeblade ezisetyenziselwa injongo ngokubanzi kunye nezidibeneyo, ezenzelwe ukusebenza kakuhle kwiintlobo ezimbini okanye ngaphezulu zokusika. (Iiblade ezidibeneyo zenzelwe ukusika imithi enqamlezileyo kunye nokukrazula imithi.

Iiblade ezisetyenziswa ngokubanzi zenzelwe ukwenza zonke iintlobo zokusikwa, kuquka iplywood, umthi oqinisiweyo kunye nemelamine.) Oko kwenziwa ngcono yiblade kuxhomekeka, ngokuyinxenye, kwinani lamazinyo, ubungakanani bomqala, ubume bezinyo kunye ne-engile yehoko (i-engile yezinyo).

Ngokubanzi, iiblayidi ezinamazinyo amaninzi zivelisa ukusika okuthambileyo, kwaye iiblayidi ezinamazinyo ambalwa zisusa izinto ngokukhawuleza. Umzekelo, iblayidi eyi-10 intshi eyenzelwe ukukrazula imithi, idla ngokuba namazinyo ambalwa ukuya kuma-24 kwaye yenzelwe ukususa izinto ngokukhawuleza kubude bengqolowa. Iblayidi yokukrazula ayenzelwanga ukuvelisa ukusika okuthambileyo njengesipili, kodwa iblayidi yokukrazula elungileyo iya kuhamba phakathi komthi onzima ngaphandle komgudu omkhulu kwaye ishiye ukusika okucocekileyo ngaphandle kokufumana amanqaku amaninzi.

Kwelinye icala, i-crosscut blade yenzelwe ukuvelisa ukusika okuthambileyo phezu kwengqolowa yomthi, ngaphandle kokuqhekeka okanye ukukrazuka. Olu hlobo lwe-blade ludla ngokuba namazinyo angama-60 ukuya kuma-80, kwaye inani eliphezulu lamazinyo lithetha ukuba izinyo ngalinye kufuneka lisuse izinto ezincinci. I-crosscut blade yenza ukusika okuninzi ngokukodwa njengoko ihamba esitokhweni kune-blade ekrazukileyo kwaye, ngenxa yoko, ifuna izinga lokutya elicothayo. Isiphumo sisisikelo esicocekileyo emaphethelweni kunye nomphezulu osikiweyo ogudileyo. Nge-crosscut blade yomgangatho ophezulu, umphezulu osikiweyo uya kubonakala ucocekile.

I-gullet yindawo ephambi kwezinyo ngalinye ukuvumela ukususwa kwe-chip. Kwinkqubo yokukrazula, isantya sokutya siyakhawuleza kwaye ubungakanani be-chip bukhulu, ngoko ke i-gullet kufuneka ibe nzulu ngokwaneleyo ukuze ikwazi ukuphatha izinto ezininzi. Kwi-crosscutting blade, ii-chips zincinci kwaye zincinci ngezinyo ngalinye, ngoko ke i-gullet incinci kakhulu. Ii-gullets kwezinye ii-crosscutting blades nazo zincinci ngabom ukuze kuthintelwe isantya sokutya esikhawulezayo, nto leyo enokuba yingxaki ngakumbi kwi-radial-arm kunye ne-sliding miter saws. Ii-gullets ze-combination blade zenzelwe ukuphatha zombini ukukrazula kunye nokukrazula. Ii-gullets ezinkulu phakathi kwamaqela amazinyo zinceda ekususeni inani elikhulu lezinto eziveliswa ekukrazuleni. Ii-gullets ezincinci phakathi kwamazinyo aqokelelweyo zithintela isantya sokutya esikhawulezayo ekukrazuleni.

Iiblade zesarha ezijikelezayo ziza noluhlu olubanzi lwamazinyo, yonke into ukusuka kumazinyo ali-14 ukuya kwi-120. Ukuze ufumane amanxeba acocekileyo, sebenzisa iblade enenani elichanekileyo lamazinyo ukuze uyisebenzise. Izinto ezisikiweyo, ubukhulu bayo, kunye nendlela ezibekwe ngayo iinkozo xa kuthelekiswa neblade yesarha zinceda ekumiseleni ukuba yeyiphi iblade efanelekileyo. Mhlawumbi into ephambili ekufuneka uyiqwalasele xa ukhetha iblade yesarha sisiphumo esifunekayo. Iblade enenani eliphantsi lamazinyo idla ngokusika ngokukhawuleza kuneblade enenani eliphezulu lamazinyo, kodwa umgangatho wokusikwa urhabaxa, nto leyo engenamsebenzi nokuba ungumfoti. Kwelinye icala, iblade enenani eliphezulu lamazinyo ukuze uyisebenzise ivelisa amanxeba amancinci aphela etshisa izinto, nto leyo engenakuvunyelwa ngumenzi weekhabhathi.

Incakuba enamazinyo ambalwa ukuya kwi-14 iyasika ngokukhawuleza, kodwa inzima. La mazinyo akrazula neyona nto ityebileyo ngokulula, kodwa ukusetyenziswa kwawo kulinganiselwe. Ukuba uzama ukusika izinto ezincinci ngencakuba enamazinyo angaphantsi kwama-24, uya kuyicola loo nto.

I-blade yokuyila ngokubanzi. Leyo iza neesarha ezijikelezayo ezingama-71.4-intshi. inamazinyo angama-24 kwaye inika ukusika okucocekileyo kodwa okuqinileyo. Ukuba uyifaka kwi-frame nge-stock ephindwe kabini, apho ukuchaneka nokucoceka kokuyila kulandela isantya kunye nokulula kokuyila, isenokuba yi-blade kuphela oza kuyidinga.

Iblade enamazinyo angama-40 isebenza kakuhle kwiintlobo ezininzi zokusikwa kweplywood. Iiblade ezinamazinyo angama-60 okanye angama-80 kufuneka zisetyenziswe kwi-plywood ene-veneer kunye ne-melamine, apho ii-veneer ezincinci zinokuqhuma ngaphantsi kwe-cut, uphawu olwaziwa ngokuba yi-tearout. I-MDF ifuna amazinyo angaphezulu (90 ukuya kwi-120) ukuze ifumane ukusika okucocekileyo.

Ukuba wenza umsebenzi omninzi wokugqiba—umzekelo, ukufaka i-crown molding—udinga isikali esicocekileyo esifuna amazinyo amaninzi. Ukusika ii-miter ngokuyintloko kukunqumla i-engile, kwaye ii-blades ezinamazinyo aphezulu zihlala zisebenza kakuhle xa zisika kwi-grain. I-blade enamazinyo angama-80 nangaphezulu inikezela ngezikali ze-miter ezicacileyo ozifunayo.
