Precision Grinding

Fertilla provides comprehensive roll grinding services for a variety of industries. Our precision roll grinding experience provides our customers with the assurance that tolerances will be met and well documented.

At Fertilla, precision tolerances are not a problem! We can hold precision tolerances down to .000030 TIR and .000050 straightness on certain applications. We routinely hold .0002 T.I.R. and straightness tolerances on paper industry calendar rolls.
