Precision Honing Process

Honing is an abrasive machining process used to create a precision ID surface suitable for sealing. A honing head containing honing stones grinds a bore to a desired size and surface finish. Honing a cylinder can correct ovality and a scratched surface, commonly found on repair cylinders. Honing is also used to create a consistent bore size at the right clearance.

Maximum Honing Length 30′
Maximum Inside Diameter 22″
Minimum Inside Diameter 2.0″
Tolerance Achievable as per customer spec
Typical Surface Finish as per customer spec

Honing FAQs

We can hone from a 2.0” to 22” inside diameter up to a length of 30’.

Yes, we recommend honing the barrel on most cylinder repairs. It removes light scratches and ovality to ensure optimal seal performance. Honing can also fix deeper scratches but doing so may require additional work or replacement of the piston and gland if the clearance becomes too great.
