(7) i-engeli ye-sawtooth

Imingcele ye-engeli ye-sawtooth iyinkimbinkimbi kakhulu futhi ichwephesha kakhulu, futhi ukukhethwa okulungile kwemingcele ye-engeli ye-saw blade kuyisihluthulelo sokunquma ikhwalithi yokusaha. Amapharamitha ama-engeli abaluleke kakhulu i-rake angle, i-engeli yokusiza kanye ne-wedge angle.

I-engeli ye-rake ithinta kakhulu amandla asetshenziswa ekusaheni amapulangwe okhuni. Uma i-engeli ye-rake iba nkulu, kuba ngcono ukucija kwe-sawtooth, ukusaha kulula, kanye nomzamo omncane wokusunduza impahla. Ngokujwayelekile, uma impahla ezocutshungulwa isithambile, kukhethwa i-engeli ye-rake enkulu, ngaphandle kwalokho kukhethwa i-engeli encane ye-rake.

(8) Ukukhetha indawo yokuvula

I-aperture iyipharamitha elula, ekhethwa ngokuyinhloko ngokuvumelana nezidingo zemishini, kodwa ukuze kugcinwe ukuzinza kwe-saw blade, kungcono ukusebenzisa imishini ene-aperture enkulu yama-saw blades angaphezu kuka-250MM. Njengamanje, ububanzi bezingxenye ezijwayelekile eziklanyelwe ngaphakathiokwasekhayaizimbobo eziningi ezingu-20MM ezinobubanzi obungu-120MM nangaphansi, izimbobo ezingu-25.4MM ezingu-120-230MM, nezimbobo ezingu-30 ezingaphezu kuka-250. Ezinye izinto zokusebenza ezingeniswa kwamanye amazwe nazo zinezimbobo ezingu-15.875MM. Ukuvuleka komshini kwamasaha anama-blade amaningi kuyinkimbinkimbi. , Okuningi kufakwe ukhiye wokuqinisekisa ukuzinza. Kungakhathaliseki ukuthi ubukhulu be-aperture, ingashintshwa nge-lathe noma umshini wokusika ucingo. I-lathe ingakwazi ukuguqula i-gasket ibe yindawo enkulu yokuvula, futhi umshini wokusika ucingo unganweba imbobo ukuze uhlangabezane nezidingo zemishini.

Uchungechunge lwamapharamitha afana nohlobo lwekhanda lokusika ingxubevange, impahla ye-substrate, ububanzi, inombolo yamazinyo, ubukhulu, ukuma kwezinyo, i-engeli, kanye nendawo yokuvula kuhlanganiswe kube okuphelele.i-carbidei-saw blade. Kufanele ikhethwe ngokunengqondo futhi ifaniswe ukuze inikeze umdlalo ogcwele izinzuzo zayo.
