How much material can be removed by honing?
The amount of Material Removal when Honing(abrasive flow machining) can be controlled to remove as little as . 001” and will depend on target set by customer. The rougher the starting surface finish is, the more material removal will be needed to achieve the best finish possible.”
What grit is best for honing cylinders?
In the case of most automotive combustion cylinders, 120 grit works for older cast ring sets or where the cylinder has been re-bored and is a little rough. Hones with 180 to 240 grits are good choices for general deglazing where the cylinder is not going to be bored or honed.
Do you need new piston after honing?
More often than not, you will need to hone your cylinder when replacing the piston rings. That is because honing creates small crosshatches in the surface of the cylinder, to allow the wall of the component to retain oil and provide lubrication for the piston ring.
What size hone do I need?

What grit hone for seals rings?
Recommended hone grit specification: moly-face or cast iron top ring 280-320 grit. Chrome face top ring: 220-280 grit. Finished hone with a 22 to 24 degree cross-hatch pattern off horizontal axis.
