1. Ukukhethwa kobubanzi 

Ububanzi be-saw blade buhlobene nemishini yokusaha esetshenziswayo kanye nobukhulu bomsebenzi osikwayo. Ububanzi be-saw blade buncane, futhi ijubane lokusika liphansi; ububanzi be-saw blade buphakeme, futhi izidingo ze-saw blade nemishini yokusaha ziphakeme, nokusebenza kahle kwe-sawing nakho kuphezulu. I-diameter yangaphandle ye-saw blade kufanele ikhethwe ngokuvumelana namamodeli ahlukene we-circular saw machine. Sebenzisa i-saw blade enobubanzi obungaguquki. Ububanzi bezingxenye ezijwayelekile yilezi: 110MM (4 amayintshi), 150MM (6 amayintshi), 180MM (7 amayintshi), 200MM (8 amayintshi), 230MM (9 amayintshi), 250MM (10 amayintshi), 300MM (12 amayintshi), 350MM ( Amayintshi angu-14), 400MM (16 amayintshi), 450MM (18 amayintshi), 500MM (20 amayintshi), njll. Izindwani zamasaha aphansi amasaha ephaneli aklanywe kakhulu ukuthi abe ngu-120MM. 

2. Ukukhethwa kwenani lamazinyo

Inani lamazinyo amazinyo asaha. Ngokuvamile, uma kukhona amazinyo amaningi, imiphetho yokusika ingasikwa ngesikhathi seyunithi futhi ngcono ukusebenza kokusika. Kodwa-ke, amazinyo amaningi okusika adinga i-carbide enosimende, futhi intengo ye-saw blade izoba phezulu, kodwa amazinyo asaha aminyene kakhulu. , umthamo we-chip phakathi kwamazinyo uba mncane, ongabangela kalula ukushisa kwe-saw blade; ngaphezu kwalokho, kunamazinyo amasaha amaningi kakhulu, futhi lapho izinga lokudla lingafaniswa kahle, inani lokusika izinyo ngalinye lizoba lincane kakhulu, elizoqinisa ukungqubuzana phakathi komkhawulo wokusika kanye ne-workpiece, okuthinta impilo yesevisi ye- blade. . Imvamisa ukuhlukana kwamazinyo kuba ngu-15-25mm, kanti inani elanele lamazinyo kufanele likhethwe ngokuya ngezinto ezisahayo.
