I.D. Honing

Midway Grinding Inc. provides its customers with supreme quality I.D. honing services. We hone quantities from single pieces to yearly volumes in the hundreds of thousands.

I.D. honing is a specialty internal bore finishing process that provides exceptional roundness, surface finish, as well as bore sizing accuracy and precision.

The rotational and stroke movement of the honing tool produces a bore action that removes peak points present on the inside of components

Close tolerances are achieved and maintained throughout the process.

Since certain internal grinding operations also require I.D. honing in order to properly maintain specifications, it has been beneficial in providing a one stop solution for our customers.

Cross grinding and single stroke finishing applications are also offered at Midway Grinding Inc to compliment our traditional honing machines.

We use Sunnen Bore Gauging and Federal Air Gauging to measure the internal bores, and Federal Formscan and Taylor Hobson Taylorond 365 for roundness, concentricity and cylindricity measurements.

  • High Precision bore sizing
  • Roundness to .000030" Max
