Gunn Machine & Tool Company can restore the precision and accuracy of machine spindle taper seats, on-site. We use special precision grinding & valve grinding machine equipment, designed and built by us, for this purpose.

 

Our machines feature a set up gage, which is indicated in to your machine’s spindle, setting the proper geometry for grinding the seat, on taper, regardless of the machines alignments.

 

Rotating the machine spindle, as we grind, ensures the seat will be concentric to the spindle’s rotation within its bearing center line, just as in the machines normal operation.

 

This method eliminates the error of tolerance stacked up upon assembly and is the most accurate method of grinding the taper seat true to spindle rotation. We have used this method on new spindles, for machine and spindle manufacturers, when closer tolerances than the norm, are required by their customers.
