MASTERING THREAD ROLLING – SETUP PROCESS

MASTERING THREAD ROLLING – SETUP PROCESS

The fourth step in proper rolling is setup of the Process. Using sacrifice material- program a .600” length to test roll a .500” long part, Insure the material will not hit faceplate. Pre-turn for rolling = Mean of the Pitch or .465” 30’ chamfer starting at .010” +0.0...
