- Precision finish of a cylinder bore
- Honing may be considered a self-truing grinding process - [1]
Other Means to Bore Finishing
- Dedicated machines and cutters can also be used (boring machines), but the boring bit can also be mounted on a mill - [2]
- Drilling - good for only 10 mil in 1" or larger drills - [3]
- Milling holes - 1 mil with a boring bar [4], from Practical Machinist - [5]
Seamless Tube, Seamed, and DOM
- DOM has a seam, so it's not seamless. It is processed over a mandrel to hide seam.
- Seamless is actually extruded - a seam is never formed
- Seamed is welded
- DOM is welded then drawn over a mandrel
