For slide milling, if depth of cut is more that 1.5D then reduce the recommended feed rate, start with 75% of the above values then increase to the above values to find the ideal parameters for your setup ideally the max run out should max <0.010mm with the maximum rigidity possible.

If the machine can't make the RPM then try the following Vf=fz*n*z (n=actual RPM of the machine)
