ball mill trajectory

  • USAMethod of determining cutting trajectory in N

    In a numerical control machining system a leftover area on a work produced by cutting the work with a larger diameter ball end mill is cut with a small diameter ball end mill. When the cutting trajectories of the small diameter ball end mill are determined the leftover portions are identified in the directions of the cutting trajectories for the larger diameter ball end mill which are set at

  • Choose right speed to improve ball mill grinding

    In order for the ball mill to perform normal grinding operations its working speed must be less than the critical speed. Ball mills generally work in a "dropped" state. There are many working speeds to achieve this working state but there must be the most favorable working speed. 1. If the rotating speed is low the ball in the ball mill
