Ngingayikhetha Kanjani I-Blade Efanele Yokusaha

Ukwenza izicucu ezibushelelezi neziphephile ngesaha lakho letafula, isaha lengalo eliqondile, isaha lokusika noma isaha le-sliding compound miter kuncike ekubeni ne-blade efanele ithuluzi kanye nohlobo lokusika ofuna ukulwenza. Akukho ukushoda kwezinketho zekhwalithi, futhi inani elikhulu lamakhasi atholakalayo lingadida ngisho nomsebenzi wokhuni onolwazi.

I-blade izosetshenziswa kuluphi uhlobo lwesaha? Amanye ama-blade aklanyelwe ukusetshenziswa kuma-saha athile, ngakho-ke kuzodingeka uqiniseke ukuthi uthola i-blade efanele ithuluzi. Ukusebenzisa uhlobo olungalungile lwe-blade kusaha cishe kuzoletha imiphumela emibi futhi kwezinye izimo kungaba yingozi.

Yiziphi izinto ezizosetshenziswa i-blade ukusika? Uma udinga ukusika izinto eziningi ezahlukene, lokho kuzothinta ukukhetha kwakho. Uma usika uhlobo olulodwa oluningi lwezinto (i-melamine, isibonelo) lokho kuchwephesha kungathinta nokukhetha kwakho.

Izinto Ezibalulekile Ze-Saw Blade Ama-saw blade amaningi aklanyelwe ukunikeza imiphumela yawo emihle kakhulu ekusebenzeni okuthile kokusika. Ungathola ama-blade akhethekile okuklebhula amapulangwe, ukusika amapulangwe axubile, ukusika i-plywood enama-veneered namaphaneli, ukusika ama-laminate namapulasitiki, ukusika i-melamine nokusika izinsimbi ezingezona i-ferrous.

Ama-blade amaningi esaha aklanyelwe ukunikeza imiphumela emihle kakhulu ekusebenzeni okuthile kokusika. Ungathola ama-blade akhethekile okuklebhula izingodo, ukusika izingodo ezihlanganisiwe, ukusika i-plywood ene-veneered kanye namaphaneli, ukusika ama-laminate namapulasitiki, ukusika i-melamine kanye nokusika izinsimbi ezingezona i-ferrous. Kukhona futhi ama-blade ajwayelekile kanye nezinhloso ezihlanganisiwe, aklanyelwe ukusebenza kahle ezinhlotsheni ezimbili noma ngaphezulu zokusikwa. (Ama-blade ahlanganisiwe aklanyelwe ukusika nokuklebhula.

Ama-blade ajwayelekile aklanyelwe ukwenza zonke izinhlobo zokusikwa, kufaka phakathi i-plywood, ukhuni olunama-laminated kanye ne-melamine.) Lokho i-blade ekwenzayo kangcono kunqunywa, ngokwengxenye, yinani lamazinyo, usayizi womhubhe, ukwakheka kwezinyo kanye ne-hook angle (i-angle yezinyo).

Ngokuvamile, ama-blade anamazinyo amaningi akhipha ukusika okubushelelezi, kanti ama-blade anamazinyo ambalwa asusa izinto ngokushesha. I-blade engu-10″ eyenzelwe ukuklebhula izingodo, isibonelo, ivame ukuba namazinyo ambalwa afinyelela ku-24 futhi yenzelwe ukususa izinto ngokushesha ubude bezinhlamvu. I-blade yokuklebhula ayiklanyelwe ukukhipha ukusika okubushelelezi njengesibuko, kodwa i-blade yokuklebhula enhle izodlula okhunini oluqinile ngomzamo omncane futhi ishiye ukusika okuhlanzekile ngaphandle kokuthola amaphuzu amaningi.

Ngakolunye uhlangothi, i-crosscut blade yenzelwe ukukhiqiza ukusika okubushelelezi phezu kwenhlamvu yokhuni, ngaphandle kokuqhekeka noma ukudabuka. Lolu hlobo lwe-blade luvame ukuba namazinyo angu-60 kuya kwangu-80, futhi inani lamazinyo aphezulu lisho ukuthi izinyo ngalinye kufanele lisuse izinto ezincane. I-crosscut blade yenza ukusika okuningi ngakunye njengoba ihamba esitokisini kune-crap blade futhi, ngenxa yalokho, idinga izinga lokuphakela eliphansi. Umphumela uba ukusika okuhlanzekile emaphethelweni kanye nobuso obushelelayo. Nge-crosscut blade yekhwalithi ephezulu, ubuso obusikiwe buzobonakala bucwebezelisiwe.

I-gullet yindawo ephambi kwezinyo ngalinye ukuze kuvunyelwe ukususwa kwe-chip. Emsebenzini wokuklebhula, izinga lokuphakelwa liyashesha futhi usayizi we-chip mkhulu, ngakho-ke i-gullet idinga ukujula ngokwanele ukuze ikwazi ukuphatha inani elikhulu lezinto okufanele ikwazi ukuziphatha. Ensikeni yokusika, ama-chip mancane futhi mancane ngezinyo ngalinye, ngakho-ke i-gullet incane kakhulu. Ama-gullet kwamanye ama-crosscutting blades nawo mancane ngamabomu ukuze kuvinjelwe izinga lokuphakelwa elisheshayo kakhulu, okungaba yinkinga ikakhulukazi kuma-radial-arm kanye nama-sliding miter saws. Ama-gullets ensikeni ehlanganisiwe aklanyelwe ukuphatha kokubili ukuklebhula kanye nokusika. Ama-gullet amakhulu phakathi kwamaqembu amazinyo asiza ekususeni inani elikhulu lezinto ezikhiqizwa ekuklebhuleni. Ama-gullet amancane phakathi kwamazinyo aqoqwe avimbela izinga lokuphakelwa elisheshayo kakhulu ekuklebhuleni.

Ama-sawblade ayindilinga anezinhlobo eziningi zamazinyo, konke kusuka kumazinyo ayi-14 kuya kwangu-120. Ukuze uthole ukusika okuhlanzekile, sebenzisa i-blade enenani elifanele lamazinyo ukuze usetshenziswe. Izinto ezisikwayo, ubukhulu bayo, kanye nokuqondiswa kwezinhlamvu uma kuqhathaniswa ne-sawblade kusiza ekunqumeni ukuthi iyiphi i-blade engcono kakhulu. Mhlawumbe isici esibalulekile okufanele usicabangele lapho ukhetha i-sawblade umphumela ofiselekayo. I-blade enenani eliphansi lamazinyo ivame ukusika ngokushesha kune-blade enenani eliphezulu lamazinyo, kodwa ikhwalithi yokusika iqinile, okungabalulekile ukuthi ungumhleli wefreyimu. Ngakolunye uhlangothi, i-blade enenani elikhulu lamazinyo ukuze isetshenziswe iveza ukusika okuhamba kancane okugcina kushise impahla, okungekho umenzi wekhabethe ongayibekezelela.

I-blade enamazinyo ambalwa afinyelela ku-14 isika ngokushesha, kodwa ngamandla. Lawa ma-blade adabula ngisho ne-stock ejiyile kalula, kodwa ukusetshenziswa kwawo kulinganiselwe. Uma uzama ukusika izimpahla ezincane nge-blade enamazinyo angaphansi kuka-24, uzoyicola leyo nto.

I-blade ejwayelekile yokubiyela. Leyo eza ne-saw eziyindilinga engu-71.4-intshi. inamazinyo angu-24 futhi inikeza ukusika okuhlanzekile kodwa okuqinile. Uma ufaka uhlaka oluphindwe kabili, lapho ukunemba nokuhlanzeka kokusika kulandela isivinini kanye nobulula bokusika, kungaba yi-blade kuphela oyoyidinga.

I-blade enamazinyo angu-40 isebenza kahle kakhulu ekusikeni okuningi kwe-plywood. Ama-blade anamazinyo angu-60 noma angu-80 kufanele asetshenziswe ku-plywood ene-veneer kanye ne-melamine, lapho ama-veneer amancane engase aqhume khona ngaphansi kokusikwa, isici esaziwa ngokuthi i-tearout. I-MDF idinga amazinyo engeziwe (90 kuya ku-120) ukuze ithole ukusikwa okuhlanzekile kakhulu.

Uma wenza umsebenzi omningi wokuqeda—ukufaka i-crown molding, isibonelo—udinga ukusika okuhlanzekile kakhulu okudinga amazinyo engeziwe. Ukusika ama-miter empeleni kuwukusika nge-engeli, futhi ama-blade anamazinyo amaningi ngokuvamile asebenza kahle kakhulu lapho esika uhlamvu. I-blade enamazinyo angu-80 noma ngaphezulu inikeza ukusika kwama-miter okuqinile okufunayo.
