1. Ukukhethwa kwe-engeli ye-sawtooth

Imingcele ye-engeli yengxenye ye-sawtooth iyinkimbinkimbi futhi iphrofeshinali, futhi ukukhethwa okufanele kwamapharamitha e-engeli ye-saw blade kuwukhiye wokunquma 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, i-sawing ilula, kanye nomzamo omncane odingekayo ukusunduza into. Ngokujwayelekile, uma impahla ezocutshungulwa isithambile, kukhethwa i-engeli ye-rake enkulu, ngaphandle kwalokho kukhethwa i-engeli encane ye-rake.

I-engeli ye-sawtooth yindawo ye-sawtooth lapho usikwa. I-angle yamazinyo ithinta ukusebenza kokusika. Umthelela omkhulu ekusikeni i-engeli yerake engu-γ, i-engeli yokukhulula engu-α, kanye ne-engeli ye-wedge engu-β. I-engeli yeraki γ yi-engeli  yokungena ye-sawtooth. Uma i-engeli ye-rake iba nkulu, ukusika kuba lula. I-engeli ye-rake ngokuvamile iphakathi kuka-10-15 ° C. I-engeli yokusiza i-engeli ephakathi kwe-sawtooth nendawo ecutshunguliwe, umsebenzi wayo ukuvimbela ukungqubuzana phakathi kwe-sawtooth nendawo ecutshunguliwe, i-engeli yokukhulula inkulu, i-friction encane, kanye nokushelela komkhiqizo ocutshunguliwe. I-engeli yangemuva ye-saha ye-carbide saw blade ngokuvamile isethwe ku-15°C. I-engeli ye-wedge isuselwa ku-rake nama-engeli okusiza. Kodwa i-angle ye-wedge ayikwazi ukuba yincane kakhulu, idlala indima ekugcineni amandla, ukuchithwa kokushisa nokuqina kwamazinyo. Isamba se-engeli ye-rake γ, i-engeli yangemuva engu-α kanye ne-engeli ye-wedge β ilingana no-90°C.

2. 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 eziklanywe eShayina ngokuvamile ziyizimbobo ezingu-20MM ezinobubanzi obungu-120MM nangaphansi, izimbobo ezingu-25.4MM ezingu-120-230MM, nezimbobo ezingu-30 ezingaphezu kuka-250. Eminye imishini engenisiwe nayo inezimbobo 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 ingafakwa nge-gasket endaweni enkulu, futhi umshini wokusika ucingo unganweba imbobo ukuze uhlangabezane nezidingo zemishini.

Uchungechunge lwamapharamitha njengohlobo lwekhanda lokusika ingxubevange, izinto ze-substrate, ububanzi, inombolo yamazinyo, ukujiya, ukuma kwezinyo, i-engeli, kanye nendawo yokuvula kuhlanganiswe ibe i-hard alloy saw blade. Kufanele ikhethwe ngokunengqondo futhi ifaniswe ukuze inikeze umdlalo ogcwele izinzuzo zayo.
