Hi I have a 1999 Haas VF0 that I'm fighting deflection.
Have to make multiple repeat passes to get close to my feature dimensions.
I have installed: all new ball screws in all axis, Z axis linear rails and a new spindle all within the last 6 months.
For example - 1/2 niagra 3 flute 2" loc in Haimer shrink fit .0002" runout
Cutting Aluminum
7500 rpm.
1.5" doc
.020" radial
50ipm
I have 2000 lbs drawbar pressure.
getting .007" off of programmed feature at the top and .013" at the bottom both X and Y are the same.
after running 2 more (spring passes) i was .001" over on top and .0025" on bottom.
Because of the taper it makes most sense that the problem is in Z.
Open to any suggestions.
