1) Freze b\u0131\u00e7a\u011f\u0131 \u00e7ok di\u015fli bir kesicidir. Frezeleme yaparken kesicinin her bir kesicisi torna tak\u0131m\u0131 ve matkap ucu gibi s\u00fcrekli kesmez, fas\u0131lal\u0131 keser ve kesicinin \u0131s\u0131 da\u011f\u0131l\u0131m\u0131 ve so\u011futma ko\u015fullar\u0131 iyidir.

T\u0131rmanman\u0131n yukar\u0131daki dezavantajlar\u0131 yoktur. Ancak frezeleme i\u015flemi s\u0131ras\u0131nda i\u015f par\u00e7as\u0131n\u0131n ilerlemesi tabla tahrik vidas\u0131 ile somun aras\u0131ndaki bo\u015fluktan etkilenir. Frezelemenin yatay bile\u015feni, i\u015f par\u00e7as\u0131n\u0131n besleme y\u00f6n\u00fc ile ayn\u0131 oldu\u011fu i\u00e7in, frezeleme kuvveti \u00e7ok b\u00fcy\u00fck ve k\u00fc\u00e7\u00fck olacak, bu da tablan\u0131n hareket etmesine ve besleme miktar\u0131n\u0131n e\u015fit olmamas\u0131na, hatta b\u0131\u00e7a\u011fa veya makineye zarar vermesine neden olacakt\u0131r. Bu nedenle, a\u015fa\u011f\u0131 kesimli frezelemeyi benimsemek i\u00e7in uzunlamas\u0131na besleme vidas\u0131ndaki bo\u015flu\u011fu ortadan kald\u0131racak bir cihaza sahip olmak gereklidir. Bununla birlikte, genel freze makinesi vida somununun bo\u015flu\u011funu ortadan kald\u0131rmaz ve sadece yukar\u0131 kesme y\u00f6ntemi kullan\u0131labilir. Ek olarak, d\u00f6k\u00fcm ve d\u00f6vme y\u00fczeyinin p\u00fcr\u00fczlendirilmesi i\u00e7in, a\u015fa\u011f\u0131 frezeleme \u00f6nce tak\u0131m\u0131n a\u015f\u0131nmas\u0131n\u0131 \u015fiddetlendirir \u00e7\u00fcnk\u00fc di\u015f \u00f6nce siyah deri ile temas eder. \u015eu anda, yukar\u0131 y\u00f6nl\u00fc frezeleme i\u00e7in de uygundur.<\/p><\/div>\n
