Hand honing apparatus
On an existing processing machine – like a milling machine or a lathe – Mu-Tools offers manual honing devices that allow the machine to be converted into a low-cost honing machine.
Thanks to the expansion system of these devices, geometry and repeatability within the micron can be achieved, even for people who have no experience in honing.
Each division of the micrometric drum represents 1 micron of expansion of the honing tool and is easily visible during the entire honing operation.
Mu-Tools 814
Hand honing apparatus type 814 for diameters of 0.6 to 1.5 mm
In the 814 honing apparatus, a friction-clutch system is incorporated to protect the small diameter honing tools.

Procedure
The tool is inserted into the bore to be machined and moved by turning and oscillating (longitudinally back and forth). The cutting edges of synthetic, natural and CBN (borazon) diamonds are pressed against the bore with a pressure which can be adjusted by a micrometric drum where each division represents a 1 micron expansion in the tool diameter.
The rotational speed of the drum allows the pressure of the diamond in the material to be adjusted ‒ by hand ‒ for rapid machining or polishing. This gives the surface of the inner wall of the cylinder its characteristic appearance with grooves (usually at an acute angle) that cross each other and extend diagonally in the cylinder (also called cross grinding). This gives the cylinder defined roughness properties with high residual adhesion for engine lubricant (hydraulic oils, engine oils).
