What is a Honing machine?

A honing machine is one of the machines used for surface finishing, and it rotates while crushing the inner surface of a cylinder with multiple grindstones attached in a stick shape to finish the inner surface. Since it is not possible to cut a lot at once, it is common to use a honing machine as the final finish after cutting a cylinder with a boring machine. Similar to an internal grinding machine, but a honing machine can machine with more precise hole accuracy, roundness, and even higher surface roughness.

Application of Honing machine

It is often used to machine the inner surface of engine cylinders, which require extremely high precision, for the final finishing of cylindrical workpieces. The surface roughness is almost mirror-finished, but if you look closely, small linear scratches will cross, and engine oil will adhere to these small scratches to keep the oil film on the piston. Since it has the function of protecting the cylinder from friction with, it is a perfect machine tool for processing engine cylinders that constantly circulate high-pressure oil.
