Line Honing Machines

Line Honing Machines

Sunnen line honing equipment is fast and accurate. Our line honing machines will do the complete job of alignment and sizing main bearing bores in about 30 minutes with maximum precision. You can expect to meet or exceed original factory accuracy for alignment, roundness and size. And you can install after market four-bolt main caps and bore blocks for roller cam bearings.

In addition, Sunnen line honing machines are easy to setup and operate, allowing any shop person to operate - whether the old pro or the new hire. Upon grinding and replacing the caps, you position the block, insert and adjust the Honing Units, engage the drive arm, and set the limit stops—
you’re then ready to hone.

What is Line Honing?

A line honing machine is generally used in engine building applications, in order to bring a crankshaft bore to final size. The bore is sized by using abrasive honing stones within a mandrel that is stroked back and forth through the bore until the proper size is achieved.
