Materials have rated surface speeds for a given type of cutter.The harder the material the slower the speed.Given the diameter of the tool and the surface speed, the rpms of the spindle can be calculated.Then if the tooth load for the cutter is know, and the number of teeth, the feed rate can be determined.
We have a variety of crushing and mining equipment, if you need to know about our products, please contact us directly.
The equivalent bearing load, p, used in the rating life formula, needs to be calculated when combined radial and axial loads occur.This calculation can be somewhat complicated as it depends on the relative magnitudes of the radial and thrust loads to each other and the contact angle developed by the bearing.
