Construction of Ball Mill. The ball mill consists of a hollow metal cylinder mounted on a shaft and rotating about its horizontal axis. The cylinder can be made of metal, porcelain, or rubber. Inside the cylinder balls or pebbles are placed. The balls occupy between 30 and 50% of the volume of the cylinder. The diameter of the balls depends on ...

I took the calibration sphere from our CMM and used it to calibrate the probe. For anyone who is interested here is the program. You could do the same thing with a good ball bearing you just need to change the to the diameter of the ball bearing. I am also working a on a way to inspect the sphere after calibration to verify the calibration.

Measure the B axis of rotation parallelism to the YZ plane: For a machine with a Classic Haas Control, change Parameter 151:20 (B axis CHK TRAVL LIM) to 0.. For a machine with a Next Generation Control, change Parameter (B axis CHK TRAVL LIM) to FALSE.. Measure the parallelism of the platter to the YZ plane with the B axis at 90° and then the B axis at 90° as shown in the picture.

1. Fill the container with small metal balls. Most people prefer to use steel balls, but lead balls and even marbles can be used for your grinding. Use balls with a diameter between ½" (13 mm) and ¾" (19 mm) inside the mill. The number of balls is going to be dependent on the exact size of your drum.

Introduction. This procedure outlines how to calibrate the Active Ballscrew Compensation system. Note: The system should be calibrated only after the machine has been idle for at least 5 hours so that the axis ballscrew is at room temperature. A calibration should be done after any linear sensor part or ballscrew is replaced.
