Precision to the micron. It’s essential for honing machines. A micron is really small (.001 millimeter). To give you some perspective, a single human hair is about 80 microns in diameter. We are talking about very precise measurements indeed.
During the honing process, an abrasive rotating tool removes metal from the interior surface of a cylinder. It finishes the cylinder to an extremely uniform and precise diameter, down to the micron. It also creates a specific geometric pattern or cross-hatching on the surface.
When done right, the honing process corrects even the smallest geometric errors in the cylinder bore. The cross-hatching patterns allow for better performance with lubricants and oils, such as in engine cylinder applications.
The video below shows an example of a horizontal honing machine manufactured by Sunnen Products Company. It’s for hydraulic service facilities that resurface and repair actuators for construction, mining, farming, and forestry equipment:
Sunnen has been a global leader in honing technology and innovation since 1924. It provides precision honing solutions for an incredibly wide range of products and industries, such as fuel injectors, hydraulics, gears, small engines, oil and gas equipment, gun barrels, aerospace, and gas flow meter tubes.

Headquartered in St. Louis, Missouri, the company operates from a number of locations around the world. Technical centers, such as Sunnen AG in Ennetaach-Erlen, Switzerland, also design and manufacturer custom high-precision solutions to fit specialized honing requirements. Sunnen’s technical experts and designers work to create turnkey solutions that meet machine model, tooling, fixture design, automation, and other customer requirements.
As part of its design solutions, Sunnen AG uses Creo and Windchill PDMLink. Windchill includes integrated 3D model viewing capabilities with Creo View MCAD, a feature Sunnen AG has found particularly helpful for sharing design information with other parts of the organization.
Creo View MCAD can improve productivity by allowing everyone in an organization to easily and quickly share visual design information. For example, manufacturing engineers can define and visualize manufacturing process plans, including tooling design and work instructions, for factory-floor operations and product assembly.
In a recent article, Development Engineer Christoph Frei explained that Sunnen AG’s manufacturing fitters use Creo MCAD View to access assembly models. (The article is written in German, but you can use your browser to translate to English). Manufacturing personnel can rotate and zoom the assemblies, which saves the development team time and effort because they don’t need to create detailed drawings. Freis says that he hopes to project the models on the assembly facility walls, making it even easier for personnel to visualize and interact with the parts assemblies.
Creo View MCAD is an easy-to-use and powerful tool for anyone on the product team, from management to documentation to tooling to the assembly floor. It is one of the ways Sunnen stays true to its mission of keeping pace with customer needs while maintaining the highest standards of precision.
Here’s how one of Sunnen’s U.S. customers uses the company’s products for honing engine cylinders:
