DEBURRING

Deburring is the operation that consists of removing burrs — fine ridges or sharp edges of Metal — left on a part after mechanical processing such as machining, Profile turning, Stamping, drilling or filing. These burrs, though unavoidable, are undesirable: they hinder the fitting of parts, can break off and contaminate the Movement, cause injuries during handling and degrade the appearance. In watchmaking, where tolerances are minimal and cleanliness is essential, deburring is a systematic finishing step. It is carried out in multiple ways depending on the piece and the series: by hand (File, scraper, Tweezers, brush), by tribofinishing (the parts are agitated with abrasives in a drum or vibrating tank), by brushing, or by specific processes for micro-components. Good deburring removes sharp edges without altering functional dimensions or working surfaces. It often precedes cleaning, Surface treatments and Assembly. Discreet but essential, deburring ensures cleanliness, operational safety, and the perceived quality of watch components.
