Surface Finishing for the Watch- and Clockmaking Industry

Application Range

Industry-Specific Requirements

Manufacturing of watches and clocks is one of the most challenging mechanical tasks in production. Surface finishing of parts ranging from arbors, pivots, wheels, and crowns to cases and straps is an important aspect of this.


The extremely complex mechanism used in watches and clocks requires that each individual part be optimally deburred and polished while adhering to close dimensional tolerances.

Our Solutions for the Watch Industry

Deburring and Polishing for Extremely Smooth Surfaces

Unlike mechanical machining techniques (e.g., grinding and honing), chemical deburring does not involve mechanical loading and heating of part surfaces. With it, inaccessible edges and corners can be reached and treated very effectively. Roughness is reduced and surface defects are eliminated, leading to improved fatigue strength behavior of parts. Rounding of the edges creates thread-smooth surfaces.


Surface Treatment for Greater Functionality

Gloss, roughness, cleaning properties, and corrosion behavior are optimized through electropolishing. A part can achieve its full functionality with an electropolished surface. Sharp-edged surfaces can be reliably deburred and polished.
