Cold Rolling VS Grinding Ball Screw in CNC

  • Cold rolling: A milling process that uses extrusion (plastic deformation) between two rollers to roll the thread into a thread shape in one go. It has high processing efficiency, fast delivery and low price. Generally, it can process screws with c7 and c10 precision. It is used for general precision equipment.
  • Grinding: The ball screw is ground by a high-precision thread grinder. Generally, it can process c5, c3, c0 precision screws. It is suitable for precision CNC equipment. Such as CNC milling machines, CNC lathes, machining centers, etc.
