Rod mills are very similar to ball mills, except they use long rods for grinding media. The rods grind the ore by tumbling within the the mill, similar to the grinding balls in a ball mill. To prevent the conditions leading to rod charge tangling, the length to diameter ratio is maintained at to
Employing Finite Element Analysis (FEA) of the shaft and housing under load can predict the amount of distortion that will occur. A computer analysis of the internal workings of the bearing can show the stress distribution. Next, optimized roller crowning can be applied to minimize the reduction in bearing life.
You will calculate the RISE based on your cutter diameter. We never use a rise that is less than 2 times the cutter diameter (2X dia). If the material we are testing is fairly narrow, and we want to run several different tests, we will increase the RISE so that we can interleave the patterns together in .

Feb 09, 2007· Dave, from using my own mill I found that you can really feel when an end mill is happy with your feed rate. As long as the rotational speed is in the ball park for the size of cutter in question you'll see what I mean. Too slow and it doesn't seem to take the cut as nicely. Too fast and the machine will start complaining.
Quick setup, in which many surfaces and holes can be machined. Great for true positions and critical relationships. Face mill may be used instead of a ball nose for better finish. Excellent for multifaced prismatic parts. Removing more stock with fewer cuts. Cutting internal sharp corners.
