A precision grinding method for screw rotors using a computer numerical control (CNC) grinding wheel dressing is presented in this study. A mathematical model for screw rotor grinding is developed for a prototype based on the new screw rotor grinding machine SK7032. A spatial contact curve equation for screw rotor grinding is proposed, which includes three …

NOTE: Helix Angle has to be calculated if you are going to grind threads. The reason is that if the grinding wheel head is not rotated to the same as the lead angle the thread will have either a drunken lead or a zero lead, both of which are unacceptable. Things to Remember When Cutting Threads on a Lathe.

2. Continuous dressing, which is beneficial in large-quantity production in materials that are difficult to machine or grind.The continuous dressing enables the grinding wheel to stay sharp constantly, while maintaining intricate forms. Continuous-dress creep-feed grinding uses an overhead diamond dressing roll to plunge dress continuously during the grinding cycle.
