Vītņu frēzēšanai ir divu veidu instrumenti:
1, ) viens zobs
2, ) blīvi zobi
1. Frēzēšanas vītņu efektivitāte ar blīviem zobiem ir augsta, bet griešanas spēks ir liels!
2. Programmējot ar G02/G03 trīsasu savienojumu, ja XY tiek izmantots kā apļveida interpolācija, rīks pazeminās soli (P) Z virzienā, un smalko zobu griezējam tas samazināsies par n * P, (n ir blīvā griezēja zobu skaits).
3. Pirms vītnes frēzēšanas jāapstrādā vītnes apakšējais caurums:
1, ) Parasti urbjus izmanto nelielas apertūras apstrādei
2, ), kamēr lielais caurums tiek izfrēzēts ar gala frēzēm vai urbts ar urbšanas instrumentu
1,) viena zoba griezējs
