Honing produces a precision surface on the ID of a machined part.  The process is primarily used to improve the geometric form of a surface, but may improve surface texture or finish. High-precision parts are usually ground then honed.  Grinding determines the size and honing improves the shape.

We can grind all types of materials from .175  to 3 inch bores.  We are able to hold .0002 tolerance with a 4 micron finish.
